Where 1996 figures have not yet been produced, data for the latest available year are given. HIGHLIGHTS • There were 649 thousand live births in England and Wales in 1996, about one thousand more than in 1995. • The mean age of mother at childbirth continued to increase, reaching 28.6 years in 1996. • The number of abortions to women resident in England and Wales rose by 9 per cent to 168 thousand. This was the first increase since 1990. • There were 563 thousand deaths registered in England and Wales, a fall of three thousand compared with 1995. • In 1995 there were 283 thousand marriages, eight thousand fewer than in 1994. • The number of divorces fell for the third consecutive year reaching 154 thousand in 1996. T OTA L P O P U L AT I O N The mid-1996 resident population of England and Wales was estimated to be 52.0 million. This was an increase of 190 thousand (0.4 per cent) since mid-1995. Of the total increase between 1995 and 1996, 71 thousand was due to natural change (the excess of births over deaths) and 119 thousand to migration and other changes. This was the fourth consecutive year that the natural increase declined and net migration and other changes increased. (Figure 1) O f f i c e f o r N a t i o n a l S t a t i s t i c s 1 P o p u l a t i o n Figure 1 250 T r e n d s 9 0 | Wi n t e r 1 9 9 7 Population change and its components, 1972–73 to 1995–96, England and Wales Total change in population Thousands 200 150 100 Increase Increase 50 0 -50 Thousands 150 Decrease Natural change 100 Natural increase 50 0 Natural decrease 150 Net migration (and other changes) Thousands 100 50 Net inflow 0 -50 Net outflow -100 1972/73 77/78 82/83 The age structure of the population continues to change as a result of variation in the number of births and in net migration and increases in life expectancy (Table A and Figure 2). For example, the number of people aged 30-44 increased by 625 thousand (5.8 per cent) between 1991 and 1996 as the people born during the 1960s baby boom entered this age group while the number of 1629 year olds declined by 1,082 thousand (9.9 per cent) reflecting the decline in fertility which took place in the 1970s. Similarly, since 1994 there has been an increase in the population aged 75-84 and a decrease in the population aged 60/65-74 which can be attributed to the baby boom which followed World War I and the subsequent period of low fertility in the 1930s. The number of people aged 85 years and over increased by 160 thousand (19.8 per cent) between 1991 and 1996, largely due to improvements in life expectancy. Year 87/88 92/93 95/96 P O P U L AT I O N P R O J E C T I O N S The population of England and Wales is projected to increase slowly from 51.6 million in 1994 to 54.4 million in 2024 when it will start to decline. The age structure will change significantly over the next 40 years. The number of children under 16 will increase slightly until 2000 before declining, while the population over pensionable age is expected to increase by over 50 per cent between 1994 and 2034. The dependency ratio (the ratio of the sum of the population aged under 16 and over pensionable age to the population of working age) will remain close to the present level of 0.64 for the next 20 years and will then increase rapidly, reaching 0.80 by 2034, as people born in the ‘baby boom’ reach pensionable age. B I RT H S Local change Table B shows the population change between 1991 and 1996 for the government office regions of England and for Wales. It should be noted that estimates of subnational change from year to year are less precise than those at a national level because of greater uncertainty about migration. The only government office regions to experience a decrease in population between 1991 and 1996 were Merseyside and the North East. The South East, London, Eastern, South West and East Midlands government office regions showed the greatest population increase during this period. 2 O f f i c e f o r N a t i o n a l There were 649 thousand live births in 1996, about one thousand (0.2 per cent) more than in 1995. This was the first increase in the annual number of births since 1990. The total period fertility rate (the average total number of children that would be born per woman if current age-specific fertility rates continued) also rose slightly from 1.72 in 1995 to 1.73 in 1996. Age-specific fertility rates increased for all age groups between 1995 and 1996 except for women aged 25-29 years.

Consequently the mean age of mother at childbirth has increased over the same period, reaching 28.6 years in 1996 compared with 28.5 years in 1995 and a low of 26.1 years in the early 1970s. The percentage of births outside marriage increased from 34 per cent in 1995 to 36 per cent in 1996.

There were an estimated 790 thousand conceptions in 1995 which led to maternities or legal abortions in either 1995 or 1996. This is a fall of 11 thousand (1.4 per cent) compared with 1994 and 9 per cent lower than the peak in 1990. The underage conception rate rose by 2 per cent to 8.5 conceptions per thousand girls aged 13-15, compared with 8.3 in 1994.

This reversed the downward trend in abortions to non-residents which began in 1984. M O R TA L I T Y In 1996 some 563 thousand deaths were registered in England and Wales, a fall of nearly three thousand (0.5 per cent) compared with 1995. Between 1995 and 1996 male deaths decreased by 1.1 per cent while the number of female deaths remained the same. In 1995 life expectancy at birth was 74.2 years for men and 79.6 years for women. M A R R I AG E There were 283 thousand marriages in 1995, 8 thousand (2.7 per cent) fewer than 1994 (Figure 7). Apart from a slight increase in 1992, the number of marriages has declined each year since 1987. The average ages at first marriage and at remarriage have been increasing steadily over the last 15 years and continued to rise in 1995. Based on provisional 1995 data, average age at first marriage was 28.9 years for bachelors and 26.9 years for spinsters compared with 28.5 years and 26.5 years respectively in 1994. The average age at remarriage for divorced men and women was 41.3 years and 38.4 years respectively in 1995 compared with 41.1 years and 37.9 years in 1994. There has been a long-term decline in the age-specific mortality rates for men and women in all age groups with the exception of men aged 15-44 years (Figure 5). The reduction is particularly marked for the 1-14 and 45-64 year olds. Figure 6 shows the proportion of deaths by age in 1981 and 1996 due to selected major causes. The broad pattern has remained similar over this period although there have been some notable changes. For example, there has been an increase in the proportion of deaths due to infectious and parasitic diseases in younger age groups. This partly reflects a decline in deaths from other major causes together with an increase in meningococcal infection among 1-14 year olds, and in HIV infection among 15-44 year olds. There has also been an increase in the proportion of deaths due to cancer in men and women over 45. The infant mortality rate fell from 6.1 per thousand live births in 1995 to 6.0 in 1996, the lowest rate ever recorded in England and Wales. The perinatal mortality rate (stillbirths and deaths under 7 days per thousand live and still births) also fell in 1996, from 8.8 in 1995 to 8.6. There were 3.5 thousand stillbirths (babies born dead after 24 or more completed weeks gestation) in England and Wales in 1996.

The most important source of error in the 1991 Census was the relatively high level of under-enumeration. As a result, the Census Offices have put reducing under-enumeration, and its differential nature, as top priority in the 2001 Census research programme. The 1997 Census test provided an opportunity to try out new ideas on delivering and collecting census forms, so that enumerator resource could be concentrated on difficult areas. The census form was also redesigned to try to make it easier for households to complete for those households most susceptible to under-enumeration. national census-based estimate, and compared with the population estimate rolled forward during the previous decade (the demographic estimate.) The proposed strategy is that if the 2001 census-based estimate comes within an agreed range of plausible values, then the census count should be accepted. If not, then the demographic estimate will be believed. Despite such efforts, it is inevitable that some people will be missed. The One Number Census (ONC) is concerned with measuring the level of under-enumeration in the 2001 Census. Stages 3 and 4 The production of adjusted census counts for small areas, say wards, and ultimately to adjust, at the micro level the census output database, represent the final goals of the ONC process. Models developed from information collected in the CCS for very small areas (postcodes) would be used to estimate the number of people missed in both enumerated households and wholly missed households, for each postcode. The precise method for creating individual records and allocating them to household units has not yet been developed. The aim of the ONC project is to adjust the census for under-enumeration so that the census, the estimated under-count and rebased population estimates are integrated to give ‘one number’. The methodological work is being carried out by a joint ONS/Academic team, under the direction of Professor Ian Diamond from the University of Southampton. The work is at a development stage and may well change, but the current thinking involves four stages, namely: Stages 1 and 2 The first two stages involve producing the best estimate of the population, cross-analysed by age and sex, at national and county levels. Counts from the 2001 Census would be adjusted at county level for estimated net under-enumeration using a Census Coverage Survey (CCS) and administrative records. The county level estimates would be aggregated to produce a A consultation paper will be issued in early 1998 to all interested parties. This paper will describe the ONC methodology, as currently envisaged, including some indication on the timing of the 2001 Census outputs, and the marketing strategy for census products as far as will be know at that stage. Comments from users will be welcomed up to the end of April 1998.

O f f i c e f o r Young teenagers and alcohol in 1996 Young teenagers who drink alcohol are drinking more than they were at the beginning of the decade, according to survey findings published by ONS in October. The research was carried out among secondary school children aged 11-15 in England and 12-15 in Scotland. The increase in alcohol consumption among this age group has been fairly steady, and has occurred to a similar degree among both boys and girls. The survey found that those who drank were drinking more frequently. In England, the proportion who drank in the week before the survey was carried our rose from 21 per cent in 1990 to 27 per cent in 1996. In Scotland it rose from 14 per cent to 23 per cent over the same period. Although the proportion of pupils who drank alcohol in the week before the survey was lower than in England, in Scotland, those who did drink drank more. The average number of units of alcohol a week drunk by children of this age (based on all children, not just those who had drunk alcohol in the previous week) more than doubled over the period from 0.8 units in 1990 in both England and Scotland to 1.8 units in England, and 1.9 units in Scotland, in 1996. The average consumption figures conceal wide variations in the amounts children of this age drink. The overwhelming majority had drunk little or nothing in the previous seven days, and most of the remainder had drunk only modest amounts. However, at the other end of the scale, five per cent of boys and three per N a t i o n a l S t a t i s t i c s 7 P o p u l a t i o n T r e n d s 9 0 | cent of girls, in both countries, had drunk 15 or more units in the previous week. The survey results are published in separate volumes for England and Scotland. For publication details (and details of the related reports on Smoking among secondary school children in 1996) see page 9. Wi n t e r 1 9 9 7 II). The level for middle-aged men in Social Class V is slightly higher than for men past retirement age in Social Classes I and II.

Health in Wales A report entitled Social Class and Health has been prepared by the Welsh Office Health Statistics and Analysis Unit, based on Welsh Health Survey data. The Welsh Health Survey 1995 was a postal survey designed to provide a picture of the health of the people of Wales, the way the NHS is used and area where services could be improved. The report gives the results of a series of analyses of the survey data relating social class to a range of health-related issues. Social class is defined using six standard groups based on the work people do. The report shows that people who do unskilled manual work (Social Class V) have higher than average levels of most physical and mental illnesses and have very unhealthy lifestyles. People who do skilled or partly skilled manual work (Social Classes IV and IIIM have higher than average levels of some physical illnesses and have unhealthy lifestyles. People in professional occupations (Social Class I) have lower than average levels of some illnesses, have healthy lifestyles, and use GP and hospital services less. As an illustration of the differences found between the occupational groups, the level of ‘limiting long-term illness’ for young men in Social Class V is the same as for middle aged men in Social Class I (and not much different from that of middle-aged men in Social Class 8 O f f i c e f o r Boys have outnumbered girls at birth since records began in 1838. Over the period 199496, there were around 105 boys born for every 100 girls. A breakdown of these data by social class of father (as defined by father’s occupation) shows that boys outstrip girls regardless of occupation: sex ratios ranged from 103 to 107 boys per 100 girls in each of the social class groups (see Figure A). A magazine article published in July suggested that professional couples were more prone to have a baby boy than the general population, and were lacking baby girls. In fact, ONS birth statistics for 1994-96, based on a 10 per cent sample of records, show that professional couples gave birth to more girls than boys than any other social class. Those in social class IIIN - such as clerks and sales reps were also well endowed with girls. Social Class II - which includes business proprietors and works managers - had the highest ratio of boys to girls. The monitoring of infectious diseases started just over 100 years ago in 1895. The statistics, originally published in the Registrar General’s Weekly Return, gave the number of cases of scarlet fever, diphtheria and enteric fever, under treatment during the week, in the Metropolitan Asylum and London Fever Hospitals, together with a return from the Highgate Smallpox Hospital. The series was expanded in 1901 to include other diseases such as typhus and cholera, and to cover certain large towns. National coverage dates back to 1922 and is based on returns sent to the Registrar General by medical officers of health (now environmental health) who keep a record of all cases which have been notified to him or her under the Public Health Acts and Regulations. The last infectious disease figures published by ONS, for the quarter ending March 1997, were published in Population and Health Monitor MB2 97/3 on 24 September (see page 9 for publication details.)

This article describes the timing of the winter peak, the population affected and the main causes of death.The relationship between excess winter mortality, temperature and influenza is also explored.The peak in the number of deaths in December 1996 and January 1997 coincided with a peak in the number of deaths attributed to influenza and with low temperatures. However, the excess winter mortality was higher than expected, based on the experience of previous winters. INTRODUCTION Mortality in England and Wales is consistently higher in winter than during the rest of the year. In January 1997 a particularly sharp rise in the total number of registered deaths was observed during the routine publication of weekly death figures. The peak in deaths from all causes coincided with a sharp increase in deaths from influenza. This article quantifies the excess mortality during the 1996/7 winter and describes the timing of the winter peak. The profile of winter deaths in terms of age, sex and cause of death is examined and the results are compared with the previous three winters. The relationship between influenza, temperature and excess winter mortality in 1996/7 is explored with reference to earlier winters including 1989/90 when the last major influenza epidemic occurred. METHOD AND DEFINITIONS Throughout this article winter is defined as the four month period from December to March. Excess winter mortality (EWM) is defined as the difference between the number of deaths which occurred in winter and the average number of deaths during the preceding four months (August to November) and the subsequent four months (April to July)1. The number of excess winter deaths was calculated for separate causes of death, by ICD chapter and selected major causes, and for age and sex. The EWM provides a useful indication of the increase in mortality during winter, but it is a crude measure which can give a distorted picture of the actual effect of winter conditions on mortality. For example, any increase in mortality associated with cold temperatures in November is classified as non-winter mortality and O f f i c e f o r N a t i o n a l S t a t i s t i c s 11 P o p u l a t i o n Figure 1 T r e n d s 9 0 | Wi n t e r 1 9 9 7 Daily deaths in November 1996 to March 1997 from all causes, respiratory and circulatory diseases compared with the average daily deaths from all causes on the same days during the previous three years, England and Wales 3000 2500 Daily deaths 2000 Average 93/94 - 95/96 All causes 1500 96/97 All causes 1000 96/97 Circulatory diseases 500 96/97 Respiratory diseases 0 November December January The analysis was based on daily and monthly occurrences of deaths in England and Wales. The data were extracted from the Office for National Statistics mortality database on 17 October 1997. A small proportion of deaths which occurred during the period covered by the analysis (August 1993 to July 1997) would not have been registered when the data were extracted and are therefore excluded from the analysis. As a large proportion of these deaths would have occurred during the most recent, non-winter months (from April to July 1997), the figures presented here may slightly overestimate the EWM. The results for deaths due to injury and poisoning will be most affected by delayed registrations2. The average number of deaths during the three previous winters, from 1993/4 to 1995/6, was used as a baseline for comparison with the 1996/7 winter. Using data from only the previous three winters avoids any complications associated with the changes in the coding of the underlying cause of death and with the termination of medical enquiries, which took place in 1993.3 Of particular relevance to the current analysis is the effect these changes had on the number of deaths for which pneumonia was recorded as the underlying cause. In order to compare the main causes of death in 1996/7 with 1989/90, conversion factors were used to make allowances for these changes. SIZE AND TIMING OF THE WINTER PEAK Mortality was 29 per cent higher during the 1996/7 winter relative to the preceding and subsequent four-month periods, resulting in approximately 49 thousand excess winter deaths (EWDs). This compares with an average of 31 thousand EWDs in each of the three previous winters, when mortality was about 17 per cent higher than during non-winter periods. Figure 1 shows the number of deaths occurring on each day from November 1996 to April 1997 compared with the average number O f f i c e f o r April 1997 will lower the overall calculated EWM. This measure should therefore be interpreted with some caution. 12 March February 1996 N a t i o n a l of daily deaths over the same months during the previous three years. There was a deficit of deaths during November 1996 compared with the baseline. The number of daily deaths increased sharply during the second half of December 1996, peaking on 2 January 1997 with 2,643 deaths. Mortality remained high for about a week before declining fairly steeply during the rest of the month. The number of daily deaths continued to decline, but at a slower rate in February, falling below the average level of the previous three winters by the middle of the month. The number of daily deaths remained below the baseline for most of March and April 1997. The mortality during the 1996/7 winter was therefore characterised by a sharp peak at the beginning of January followed by a small but prolonged deficit, compared with the baseline, in March and April. This winter peak was much more pronounced than each of the three previous winters (see Figure 2a). Although the excess winter mortality in 1996/7 was higher than the baseline by about 18 thousand deaths, over the period from November 1996 to April 1997 there were only about three thousand more deaths compared with the average for these months in the three previous winters. This is partly due to the trough following the January peak and partly because the daily number of deaths was below the baseline in November 1996. The deficit of deaths following the sharp peak in January suggests that the deaths of a number of vulnerable people, who would otherwise have died within the next few months, may have been brought forward. Similarly, the size of the winter peak may have been more pronounced because a number of people whose deaths were imminent survived the preceding weeks but were then affected by some change in conditions during the peak period. Although EWM was higher during the 1996/7 winter compared with the baseline, this disguises considerable variation in previous years (see Figure 2a). For example, the figures are distorted by the fact that much of the increase in mortality during 1993/4 occurred in November and was therefore excluded from the EWM as defined here.

Respiratory diseases were recorded as the underlying cause of death for nearly half of the excess winter deaths (23 thousand deaths) (see Table 2), compared with an average of 42 per cent (13 thousand deaths) in the previous three winters. Conversely, the proportion of excess winter deaths attributed to circulatory diseases fell from 45 per cent in the baseline years to 36 per cent in 1996/7. This represents a substantial reduction from several earlier reviews which attributed at least half of all excess winter mortality to circulatory diseases.4,5 EWD per 1000 population* Males Females Males Females 0–14 15–44 45–64 65–74 75–84 85+ 1.11 1.11 1.12 1.18 1.30 1.39 1.07 1.11 1.16 1.21 1.32 1.45 0.02 0.03 0.27 1.86 7.78 22.61 0.01 0.02 0.23 1.33 5.37 20.19 All ages 1.24 1.33 0.77 1.09 *based on mid-1996 population estimates.

Mortality from circulatory diseases on the other hand increased by just 24 per cent during the winter relative to the non-winter periods. The timing and shape of the peak in daily deaths from respiratory diseases during December 1996 and January 1997 closely matches that for deaths from all causes. Although the number of deaths attributed to circulatory diseases peaks at around the same time, the preceding increase and subsequent decline in the number of deaths were more gradual than for deaths from all causes.

The fact that mortality was lower than previous years during the autumn of 1996 and spring of 1997 further exaggerates the EWM in 1996/7 compared with the baseline. DEMOGRAPHY OF THE EXCESS WINTER MORTALITY As would be expected, the majority of excess winter deaths in 1996/7 occurred in older age groups (see Figure 3). Over three quarters of the excess winter deaths were to people aged 75 years and over, with women aged 85 years and over accounting for nearly a third of the EWM. A significant proportion of the deaths which occur in younger age groups are due to injury and poisoning and are therefore often registered late2 . It is therefore likely that the figures for EWM in younger age groups, which are based on deaths which had been registered and entered onto the ONS database by 17 October 1997, may overestimate the actual number of excess deaths in these age groups. Deaths to females accounted for approximately 60 per cent of the excess winter mortality largely because of the high proportion of women in the older age groups relative to men. In each of the older age groups the percentage increase in mortality in winter was higher for women than for men but the number of winter deaths per 1,000 population was higher for men (see Table 1). Deaths from most other causes, according to ICD chapters, also increased to some extent during the winter. There was a particularly notable increase in deaths due to mental disorders and signs and symptoms which can largely be attributed to diseases associated with old age such as senile dementia and ‘senility without mention of psychosis’. Neoplasms, on the other hand, which account for a quarter of all deaths, increased by only 2 per cent during the winter, resulting in just 2 per cent of the total EWM. The number of excess winters deaths attributed to injury and poisoning is likely to be an overestimate as a significant proportion of these deaths, particularly those which occurred during the most recent, non-winter months would not have been registered when the data was extracted from the database. In terms of specific causes of death, four causes accounted for over 70 per cent of the excess winter mortality in 1996/7: pneumonia, ischaemic heart disease, cerebrovascular disease and bronchitis (see Table 3). Pneumonia accounted for nearly one third of the excess winter mortality and approximately two thirds of all respiratory deaths, while ischaemic heart disease accounted for just under one fifth of the EWM. There was an increase in mortality in the 1996/7 winter for many other specific causes of death, particularly chronic disabling diseases associated with old age such as Parkinson’s, Alzheimer’s and osteoporosis, all of which increased by about a third during the winter compared with the average non-winter levels. Other diseases which recorded a marked increase in mortality in winter included asthma (56 per cent increase), fractured neck of femur (43 per cent), hypertensive disease (34 per cent), pulmonary embolism (29 per cent), diabetes (26 per cent) and ulcer of the stomach and duodenum (24 per cent).There was a substantial increase (364 per cent) in deaths from hypothermia in the winter relative to the rest of the year although only about 100 excess winter deaths were attributed to it.

Only 375 deaths were attributed directly to influenza in the winter of 1996/7 and there were just 50 deaths for which influenza was mentioned on the death certificate other than as the underlying cause of death. However, it is likely that influenza is frequently undiagnosed and is a causal or contributory factor in many more excess winter deaths, particularly those attributed to other respiratory diseases. It has been estimated that between 1949 and 1985 there were on average 2.6 ‘hidden deaths’ associated with each death attributed to influenza and during the 1989/90 influenza epidemic this hidden factor increased to approximately nine.6 14 O f f i c e f o r N a t i o n a l J 1995 Months 1994 A S O N D J F M A M J 1996 J A S O N D J F M 1997 C O M PA R I S O N W I T H T H E 1 9 8 9 / 9 0 I N F L U E N Z A EPIDEMIC The last major influenza epidemic in England and Wales occurred during the winter of 1989/90.

The peak in the total number of daily deaths coincided with a particularly cold period from 31 December 1996 to 9 January 1997 (based on daily mean central England temperatures). Most of the deaths from influenza were also concentrated over this relatively short period with a sharp rise in deaths from 24 December to a peak of 22 deaths on 8 January followed by a steep decline to very low levels by the end of January. 15 46 22 2 28 49 20 10 *Using conversion factors to account for changes in medical enquiries and in the coding of the underlying cause of death. 7 All causes Respiratory Circulatory Influenza Temperature 10000 R E L AT I O N S H I P BETWEEN INFLUENZA, TEMPERATURE AND EXCESS WINTER MORTALITY Percentage of excess deaths 1996/7* 1989/90 Table 5 Female 12000 0 Underlying cause of death for the excess deaths occurring during the ‘epidemic periods’ in the winters of 1996/7 and 1989/90, England and Wales Circulatory disease Respiratory disease Pneumonia Influenza Male 2000 *International Classification of Diseases Ninth Revision.

In both cases the ‘epidemic period’ lasted approximately two months and was followed by a deficit of daily deaths. However, the excess mortality during the ‘epidemic period’ in 1989/90 was much higher, with about 25 thousand excess deaths compared with 15 thousand in 1996/7. Table 4 shows the proportion of EWD during the ‘epidemic periods’ in 1989/90 and 1996/7 attributable to selected causes of death. Conversion factors have been used to account for the effects of changes in the coding of the underlying cause of death and in medical enquiries which took place in 1993. The proportion of excess deaths attributable to pneumonia and to all respiratory diseases was similar during both ‘epidemic periods’. However, less than 2 per cent of the excess deaths during the ‘epidemic period’ in 1996/7 were attributed to influenza compared with 10 per cent in 1989/90 (see Table 4). The proportion due to circulatory diseases was also much lower during 1996/7. Monthly data relating to the total number of deaths from all causes and from influenza and to the mean central England temperature from August 1993 to March 1997 reveal a similar relationship between these variables (see Figure 2). There was a large increase in mortality during the 1993/4 and 1995/6 winters both of which experienced low temperatures and high numbers of influenza deaths. During the 1994/5 winter, which was relatively mild, there were fewer deaths from influenza and a smaller increase in mortality overall. The 1996/7 winter mortality appears to fit this pattern, although the total excess winter mortality appears to be higher than would be expected, particularly as 1996/7 was not an exceptionally cold winter, based on mean monthly central England temperatures. This is supported by applying the following regression equation (developed by Curwen and Devis1), describing the relationship between winter mortality, temperature and influenza: Expected EWM = 3.64I + 7,750 (5.05 - T) - 534Y + 51,870 , where T is the mean temperature ( oC) recorded for England and Wales over the four winter months I is the number of registered influenza deaths during the four winter months and Y is an additional factor relating to year number (1949-50 = 1) to allow for the underlying reduction in EWM over time. This equation was found to account for 88 per cent of the total annual variation in EWM from 1949 to 1985. Substituting 1996/7 figures into this equation gives an expected excess winter mortality of 26,634 which is considerably lower than the observed number of 49 thousand excess winter deaths.

The fact that this model, which uses temperature data averaged over long periods, fails to fit the 1996/7 data is probably related to the fact that the cold weather and associated EWM in 1996/7 were concentrated over an unusually short period compared to previous winters. There may also have been a change in the underlying downward trend of EWM over time. Although the pattern of winter deaths in 1996/7 was similar to earlier years in some respects, there were certain distinctive features. Circulatory and respiratory diseases remained the main causes of excess winter mortality, although respiratory diseases were relatively more important than during previous winters. This may suggest that influenza, which tends to be more strongly correlated with respiratory than circulatory deaths, was an important factor in the EWM in 1996/7.5 However, the proportion of excess deaths due to influenza in 1996/7 was much lower than during the previous influenza epidemic in 1989/90. Based on monthly figures, the relationship between temperature, influenza and excess winter mortality appears to have changed over time with higher excess winter mortality than expected from the temperature and levels of influenza observed during the winter of 1996/7. This may be partly explained by the fact that the excess mortality was concentrated over a short period of approximately three weeks. Moreover, the low mortality during the preceding autumn and subsequent spring exaggerated the level of EWM in 1996/7 relative to the baseline. More detailed analysis using daily and regional data from 1996/7 and previous winters would provide a fuller understanding of the link between temperature, influenza and EWM during the 1996/7 winter.

Under the Eurostat baseline scenario, the EU population will continue to grow slowly until around the year 2025 before starting to decline.The number of young people will continue to fall, while the number of older people will increase.To greater or lesser extents, all EU INTRODUCTION countries will experience declining population growth and an ageing population. National population projections by age and sex are produced by all national statistical institutes within the European Union.1 In the United Kingdom, national population projections are produced by the Government Actuary’s Department (GAD) in consultation with the Registrars General. New 1996-based projections (replacing the previous 1994-based projections2 ) are scheduled to be issued at the end of November 1997; a summary of the proposed assumptions was given in the previous issue of Population Trends3 and details of the results will be published in an ONS Population and Health Monitor early next year. However, the projections made by national institutes are not directly comparable. They can differ in a number of respects, for example in methodology, the detail of what is projected and in the frequency with which they are produced. Therefore, with the growing need to place expected demographic developments in individual countries in a wider context, there is a need for internationally consistent sets of demographic projections. A number of organisations produce such projections, notably the United Nations4 and the Statistical Office of the European Communities (Eurostat). Until now, the European Commission has used the Eurostat projections mainly for demographic, employment and regional reports and for various studies on population ageing. In the near future, the projections are also likely to be used for various environmental and economic studies. It is also expected that, as awareness of these projections increases, external use of the projections will grow. 18 O f f i c e f o r N a t i o n a l S t a t i s t i c s 8 89 0| | S u Wm i nmt ee rr 11 99 99 77 PP oo pp uu ll aa tt ii oo nn TT rr ee nn dd ss This article reports on the latest Eurostat projections for the fifteen European Union countries (EU15) covering the period 1995-2050. These projections were compiled in 1996 by Statistics Netherlands on behalf of Eurostat. Projections were also prepared for Iceland, Liechtenstein and Norway which, together with the EU15, comprise the European Economic Area (EEA). Results for these three countries are not included in this article but are summarised elsewhere.5 In the baseline scenario, it is assumed that the decline in fertility which has already occurred in recent years at younger ages will not be fully offset by future higher fertility at older ages. Therefore, although the assumed long-term fertility levels are sometimes higher than current TFRs, the decline in completed cohort fertility is assumed to continue for virtually all countries. Assumed fertility levels are then held constant for women born in or after 1990; TFRs therefore remain constant from 2035. To illustrate the inherent uncertainty of population projections, five different ‘scenarios’ were produced based on three different sets of assumptions about future fertility, mortality and migration. The central assumptions for each of the three components of population change were combined to give the ‘baseline scenario’ which is broadly consistent with a continuation of current trends. Notwithstanding the comments made above about methodological differences, in general, Eurostat’s baseline scenario is deliberately close to the latest medium (or principal) projection made by individual countries. This is true for the United Kingdom, although one or two key differences between the assumptions made in our national projections and the assumptions made by Eurostat are highlighted in this article. In the baseline scenario, long-term fertility is assumed to be below ‘replacement level’ for all countries. The highest assumption (of 1.9 children per woman) is made for Sweden, while the United Kingdom is one of eight EU countries with a long-term assumption of 1.8. This is the same assumption as currently made by GAD in the official national projections for the UK.3 The lowest assumptions are made for the countries of Southern Europe and for Germany and Austria where current fertility levels are all very low. Because of the influence of the large low fertility countries of Germany, Italy and Spain, the assumption for the UK is somewhat above the overall EU average of 1.66. The ‘high scenario’ combines the higher assumptions of future fertility, life expectancy and net migration while the ‘low scenario’ combines the lower assumptions of the three components. This pair of projections provides sharply contrasting scenarios of future population size and growth. However, age distributions do not differ greatly between them as the number of young and old people are both high in the high scenario and both low in the low scenario. Therefore, to illustrate the uncertainty relating to age structure, two additional scenarios were prepared. The ‘young scenario’ combines the assumptions of high fertility and high migration with that of low life expectancy, while the ‘old scenario’ combines high life expectancy with low fertility and low migration. Users of the projections should also always bear in mind the increasing uncertainty of population projections with time. These projections are taken forward to the middle of the next century i.e. fifty-five years from the base year of 1995. However, as illustrated later by Figure 3, the margins of uncertainty grow very wide by the end of the projection period. FERTILITY Fertility assumptions were based on an analysis of the ultimate number of children born to women by the mother’s year of birth. 6 This cohort measure is more stable than the analogous calendar year (period) measure, the total fertility rate (TFR), as it is affected only by changes in the number of children women have, and not by the timing of births within women’s lives. Actual and assumed levels of fertility for EU countries are shown in Table 1. This table shows both the average completed family size for selected birth cohorts and the TFR (the hypothetical average number of children who would be born per woman if women experienced the age-specific fertility rates of the year in question throughout their childbearing lives). TFRs fell markedly in the EU during the 1970s. Since 1980, the levels have been relatively stable in many countries, although in Southern Europe and Ireland the TFRs continued to decline strongly. As noted above, trends in the TFR are affected by changes in the timing of births and in recent years, there has been a tendency for women to delay childbearing with the numbers of births falling at younger ages and, in most countries, rising at older ages. In the high scenario, it is assumed that women born in the 1960s and 1970s will largely make up for births deferred at younger ages by higher fertility at older ages. Under this scenario, the long-term average completed family size for the EU as a whole would be 1.94 children per woman, almost identical to that achieved by the 1950 cohort who have now virtually completed their childbearing. In the low scenario, it is assumed that there will be little or no catching up. Under this scenario, average family size would continue declining, eventually reaching 1.45 for women born in or after 1990. The low scenario would be consistent with about 30 per cent of women remaining childless. Under the high scenario, TFRs would increase in all countries compared with current levels, but under the low scenario they would fall except for those countries where TFRs are currently below 1.5. M O R TA L I T Y The mortality assumptions were based on an analysis of both age and sex specific mortality rates and life expectancy at birth.7 Actual and assumed expectations of life (based on the mortality rates for the given year) are shown in Table 2. Since 1980, life expectancy at birth in the EU has increased by nearly 3.5 years for both sexes, equivalent to an average annual increase of over 0.2 years. The geographic differentials observed for fertility are not repeated for mortality. For example, in Northern Europe, life expectancy is currently well above the EU average in Sweden but below average in Denmark and, for males, in Finland. Similarly in Southern Europe, there are high life expectancy countries (e.g. Italy for both sexes and Greece for males) while Portugal has tended to have around the lowest figures in the EU. In the EU as a whole, expectation of life at birth in 1995 was 6.5 years greater for females than males. This sex differential varied from eight years in France to just over five years in the UK, Denmark, Sweden and Greece. In the baseline scenario, expectation of life at birth is assumed to increase by about six years for males by 2050 and by about five years for females. However, the rate of increase is assumed to gradually slow down. This is because mortality rates at young ages, which have the greatest impact on expectation of life, are already so low that the potential for further improvement is limited. The country differentials in the assumptions at the year 2050 (see Figure 1) are broadly similar to the current pattern.

EU15 averages will vary marginally from cohort to cohort and year to year. * All data for Germany are based on current borders. expectation of life at birth for females in the United Kingdom is currently about one year below the EU average, but by 2050, the assumptions for the UK of 80 years for males and 85 years for females are both in line with the EU average. The Eurostat assumptions for the UK are slightly more optimistic than those currently made by GAD in its national projections.3 M I G R AT I O N Mortality trends are, of course, influenced by both positive and negative factors. In the high scenario, positive influences such as improvements in preventative and curative health services and healthy lifestyles are assumed to prevail. As a result, life expectancy for males by 2050 is assumed to be three years greater for all countries than in the baseline scenario, and two years greater for females (but only one year for France). In the low scenario, the effect of these positive influences is assumed to reduce and to be counteracted by negative influences such as increases in cigarette smoking and stress. Under this scenario, life expectancy is assumed to improve by only about two years for both males and females compared with current levels. Net migration to the EU has risen sharply in recent years from about 50 thousand per year in the early eighties to nearly half a million per year in the late eighties and over one million per year in the early nineties. Although Germany has, since 1985, accounted for over half of all net migration to the EU, all countries except Ireland and Portugal experienced net inflows in the first half of the 1990s. 20 O f f i c e f o r N a t i o n a l Assumptions of net international migration for the individual countries of the EU were based on population size and past migration patterns.8 Actual and assumed net migration figures are shown in Table 3. In the baseline scenario, net migration to the EU as a whole is assumed to move from current levels to nearly 600 thousand per annum from the year 2020, broadly equivalent to the average level of the past fifteen years.

Net inflows are assumed for all countries except Ireland. In absolute terms, Germany dominates and is assumed to take one third of total net migration. Net inward migration of 45 thousand per year is assumed for the UK, making it the fifth largest recipient of migrants behind Germany, Italy, Spain and France. Compared to the size of the population, however, the net migration assumption for the United Kingdom is relatively low (see Figure 1). Net migration rates at the year 2020 are projected to be highest in Luxembourg (the smallest EU country), followed by Austria. Apart from Ireland, the lowest projected rates are for the UK, France and Finland. The average for the EU as a whole at 2020 is 1.5 per 1,000 population. In the previous (1994-based) GAD national projections for the UK, net migration of 50 thousand per year was assumed up to 2009 followed by a decline to net zero migration from 2018 onwards. These assumptions were therefore slightly higher than those made by Eurostat in the medium-term, but considerably lower in the longer-term. Indeed GAD’s long-term assumption of net zero migration was below Eurostat’s low scenario for the UK. However, net migration to the United Kingdom was high in both 1994 and 1995, and for the 1996-based projections, GAD have revised the medium-term net migration assumption upwards to 65 thousand per year and assumed that this will continue unchanged into the longer-term.3 The revised assumption is therefore now well above Eurostat’s baseline scenario, although still below their high scenario. Although the size of net migration flows to Europe could vary substantially depending largely on economic developments and migration policies, all Eurostat’s migration scenarios assume that Europe will remain an attractive region for immigrants. The high migration scenario assumes a net inflow of almost 800 thousand persons each year to the EU, which is still well below the average level of the early 1990s.

As a result, Europe’s share of the total world population, which was 20 per cent in 1960 and 14 per cent in 1990, will continue falling to only 7 per cent by 2050. In fact, alone amongst the major areas of the world shown in Figure 2, the UN projects population decline in Europe over this period. However, population growth is projected to be modest in North America and Oceania, and the population of China is projected to peak just before 2050. At the other end of the spectrum, the population of Africa, which was still estimated in 1995 to be slightly smaller than that of Europe, is projected to almost triple in size by 2050. Total European Union Eurostat’s projected trends in the size of the total population of the European Union are shown in Figure 3. The EU15 is currently estimated to number around 370 million people. Under the baseline scenario, the population would peak at around 390 million in 2023 and by 2050 it would be back to its current size. Under the low scenario, population decline would start in 2002 and by 2050 the population would number about 300 million, nearly 20 per cent below its present size. However, under the high scenario the population would continue increasing to reach nearly 450 million O f f i c e f o r N a t i o n a l S t a t i s t i c s 23 P o p u l a t i o n T r e n d s 9 0 | Wi n t e r 1 9 9 7 by 2050, some 20 per cent above its present size. But, even under this ‘extreme’ combination of high fertility, high life expectancy and high migration, population growth would have virtually ceased by the middle of the next century. population peak for the UK, but the 1996-based projections should be more consistent with the Eurostat projections in this respect (results were not available at the time of writing), because of the upward revision to the migration assumptions.] The reason for the virtual inevitability of population decline in the first half of the next century is shown by Figure 4. While net migration to the EU15 has grown in recent years and is projected to remain positive under all scenarios, the contribution of natural change (births minus deaths) to population growth has fallen steadily since the mid 1960s and will eventually become negative even under the high scenario. In the low scenario, deaths would overtake births almost immediately. Net migration overtook natural change as the main contributor to population growth in 1989 and accounted for over two thirds of the rise in the EU15 population in the first half of the 1990s. Under the low scenario, population decline would start immediately in Italy and would be occurring in all countries by 2025, but under the high scenario, only Germany, Italy and Spain would be experiencing population decline even at 2050. In 1995, there were 4.0 million births and 3.7 million deaths in the European Union. Under the baseline scenario, the annual number of deaths will begin to outnumber births around 2010. Births will fall fairly gradually as the large cohorts of women born in the mid 1960s baby boom move out of the peak childbearing ages while deaths will increase steadily, despite the assumption of improving life expectancy, as a result of population ageing. Individual countries The projected populations of the individual countries under the baseline, high and low scenarios are shown in Table 4. Under the baseline scenario, as illustrated by Figure 5, population decline would begin in the first half of the next century in all countries except Sweden and Luxembourg. Sweden is the only country where TFRs, life expectancy and net migration rates are all assumed to be well above the EU average, while Luxembourg has much the greatest assumption of net migration relative to the size of its population. Populations would peak first around 2010 in the low fertility countries of Italy, Germany and Spain. In other countries, population decline would not start until after 2025. The population of the United Kingdom is not projected to peak until 2030. [The GAD’s 1994-based national projections gave an earlier Figure 3 Germany will remain the largest of the EU countries with its population rising from 81.5 million in 1995 to a peak of nearly 85 million in 2013 (see Figure 6). In 1995, the United Kingdom was the second largest of the EU countries, but with only a slightly larger population than both France and Italy. The gap between the UK and France has been narrowing in recent years and France is projected to overtake the UK in population size at the turn of the century. The main reason for this is that the UK currently has over 100 thousand more deaths per year than France. This arises because the UK has a larger proportion of its population aged over 65 than France, and because mortality rates are higher at these ages in the UK. However, Italy’s population will fall far below that of both the UK and France during the next century, reflecting the baseline scenario assumption of 20 per cent higher fertility levels in the UK and France. A G E S T RU C T U R E Persons aged 0-19 Figure 7 shows that the number of people aged under 20 in the EU has fallen rapidly over the last twenty years from 110 million in 1975 to under 90 million in 1995. Under the baseline scenario this decline would continue, although at a slower rate, with the number of young people falling to 80 million by 2020 and to 70 million by 2050. However, the numbers under 20 at the middle of the next century could be as many as 100 million under the high scenario or as few as 50 million under the low scenario. This illustrates the dramatic effect that changes in the levels of long-term fertility could have on the size and age structure of the population.

These falls would be marginal in the Netherlands, Sweden and Denmark, but Italy, Spain, Germany and the UK are all projected to have over 1.5 million fewer persons aged under 20, and France 1 million fewer, by the year 2020. And, as shown in Figure 8(a), young people as a proportion of the total population will decline significantly in each EU country between 1995 and 2020. Despite a particularly large fall over the next twenty-five years, Ireland will still have the largest proportion (25 per cent) of young people in the EU at 2020. The smallest proportions (under 19 per cent) would be in the low fertility countries of Germany and Italy. The proportion of people under 20 in the UK will fall from just over 25 per cent in 1995 to about 22 per cent in 2020, slightly above the EU average. Although the size of the working age population will not change greatly by 2020 in the EU as a whole, Table 5 shows there are marked differences between countries. In the baseline scenario, the number of 20 to 59 year olds is projected to fall by nearly 3 million in Italy and by about 2 million in Germany. But in most other EU countries, the working age population will actually rise, and by around half a million in the UK, France and Spain. However, as with the population aged under 20, the working age population will fall as a proportion of the total population in each EU country apart from Ireland over the next 25 years although only marginally so in Spain and Portugal (see Figure 8(b)). Under the baseline scenario, the proportion of the population that is aged 20-59 in 2020 would vary from over 54 per cent in Austria to just under 50 per cent in Finland. In the UK, persons aged 20-59 would comprise nearly 53 per cent of the population in 2020, just above the EU average. Persons aged 20-59 Figure 7 shows that the population of working age (as approximated by the 20-59 age group) has risen by about one quarter since 1960 to its present size of 206 million. Under the baseline scenario, the total would not change greatly over the next twenty years, but it would then start to decline, falling to almost 170 million by 2050. Even under the high scenario, combining high levels of fertility and net migration, the working age population would be no greater in 2050 than it is now. As the baby boom generation grows older and the smaller cohorts born in the 1970s and 1980s enter the younger working ages, the working age population will become markedly older, as shown by Figure 9. In 1995, some 45 per cent of the 20-59 age group in the EU were aged over 40. However, under the baseline scenario, in twenty years time this will have risen to nearly 55 per cent. Thereafter, as the large cohorts of the 1950s and 1960s pass the age of 60, the working age population will get slightly younger.

As for individual countries, under the baseline scenario, persons aged 40-59 will outnumber those aged 20-39 in every EU country in 2020, whereas the opposite was true in 1995. Persons aged 60 and over In contrast to the population at younger ages, the number of older people is set to increase markedly in the early part of the next century. Figure 7 shows that the number of people aged over 60 has been increasing more or less continuously for many years. The rate of increase is likely to accelerate when the large cohorts born following the Second World War start to enter this age group and the increase will not level off until the smaller 1970s and 1980s cohorts start to reach the age of 60. Under the baseline scenario, the total EU population aged 60 and over would increase by one third from 76.5 million in 1995 to over 100 million by 2020, eventually levelling off at around 125 million in the 2030s. The increase in the very elderly (those aged 80 and over) would be even more dramatic: a rise of 50 per cent from 14.4 million in 1995 to about 22 million in 2020, increasing further to reach 35 million by the middle of the next century. Germany alone would have 5 million people aged over 80 in 2020. Even in the low scenario, with its relatively modest assumptions of improving life expectancy, there would be over 100 million people aged 60 and above and over 25 million aged 80 and above by the middle of the next century. Table 5 shows that all countries will experience large increases in the number of people over working age. Under the baseline scenario, Germany would have 6.5 million more people aged over 60 in 2020 than in 1995. France would have an extra 5 million while the numbers in Italy and the UK would increase by approaching 4 million. Numbers would grow by over 25 per cent over the next twenty-five years in each EU country and by over 50 per cent in the Netherlands, Luxembourg, Finland and Ireland. Even under the low scenario, all countries except Portugal would experience an increase of over 20 per cent. As a result of these changes, the proportion of older people in the population will also grow considerably as shown by Figure 8 (c) and (d). Persons aged above 60 currently comprise 20.6 per cent of the total EU population, but, under the baseline scenario, this would grow to nearly 27 per cent by 2020. This proportion would Table 5 PP oo pp uu ll aa tt ii oo nn TT rr ee nn dd ss range from over 29 per cent in Italy to under 22 per cent in Ireland. As for the very elderly, persons aged over 80 accounted for nearly 4 per cent of the total population in 1995 but this will rise to about 5.5 per cent by 2020 with this proportion varying from nearly 7 per cent in Italy to just over 3 per cent in Ireland. The UK would have 25.5 per cent of its population aged over 60 in 2020, one of the smaller proportions in the EU, and about 5 per cent aged over 80. D E P E N D E N C Y R AT I O S The different trends in prospect for the numbers of people at different ages will have a significant effect on the future proportion of dependants in the population. In this article, we use the number of persons under 20, or 60 and above, (or the sum of the two) per 100 persons aged 20-59 to give a comparable measure of dependency ratios across EU countries. This differs from the normal definition used in reporting GAD national projections2 where young dependants are taken to be those below age 16 when compulsory full-time education ends, and old dependants are taken to be those above state retirement age, currently 65 for men and 60 for women. There is, of course, an inevitable arbitrariness about any such definition. In reality, full-time education ends, and retirement starts, at a range of ages, and practices will also differ between countries. Nevertheless, it is clear from Figure 10, that the ratio of dependants to persons of working age, which has been falling over the past twenty years, will start to rise rapidly from early in the next century. The ratio of young people to those of working age, which has fallen markedly since 1970, would actually fall slightly further under the baseline scenario, but this would be far outweighed by the rapid increase in the number of older dependants. In 1995, there were 37 persons aged 60 and over for every 100 persons aged 2059, but in the baseline scenario this would rise continuously to over 50 per 100 in 2020 and to over 70 per 100 by the 2040s. The future ‘old dependency ratio’ is, however, subject to a wide range of uncertainty. In the old scenario (where high life expectancies boost the numbers of the elderly, but low fertility and migration reduce the numbers at working ages) the ratio would rise to 55 per 100 by 2020 and to 90 per 100 by 2050. Ratios would be much smaller in the young scenario, but even here they would rise to nearly 60 per 100 in the 2030s.

However, many future developments are determined, to a greater or lesser extent, by the age structure of the population alive now and can therefore be predicted with some confidence. For example, the influence of the large cohorts born following the Second World War followed by the much smaller cohorts born in the 1970s and 1980s will have a considerable influence on demographic trends in the first half of the next century. The rapid ageing of the working age population over the next twenty years, for example, is an inevitable consequence of these past birth patterns.

There, continuing high levels of fertility will inevitably lead to strong population growth well into the next century. As a result, Europe’s share of the world population will continue to fall. In common with all other EU countries, the number of older people in the UK will increase considerably as will the size of this group relative to that of the working age population. Although these will be very significant changes, the outlook for this country is far from exceptional. In Italy, for example, the effects of population ageing will be much more dramatic. By 2020, Italy will have the smallest proportion of young people, the largest proportion of older people and the oldest working age population in the EU. However, at 2020, the UK, compared with the EU as a whole, will have proportionately fewer older people, a slightly younger working age population and a below average ‘old dependency ratio’. 2020 Finland Coupled with continuing improvements in life expectancy, the ageing of the baby boom generation will also lead to a rapid growth in the size of the elderly population and consequent increases in dependency ratios. And unless fertility increases considerably from current levels, the ageing of these large cohorts will also lead to deaths far exceeding births during the first half of the next century. Even net migration at the highest levels experienced in the past would not offset this natural decrease and so the population of the EU looks virtually certain to peak in size sometime during the next fifty years. Within the European Union, the United Kingdom is assumed to have slightly above average fertility, around average life expectancy and, relative to the size of the population, below average levels of inward migration. If the assumptions for the baseline scenario are borne out in practice, the UK’s population would continue rising until about the year 2030.

It shows how earlier work adjusting 1991 census figures at national and local authority level for undercount and other factors has been extended to smaller areas in a way that produces estimates which are consistent with the estimates for larger areas. Estimates for smaller areas are needed to calculate employment, health and other indices, and as a starting point for population estimates between census years. INTRODUCTION Population statistics in Census year are generally estimates incorporating important adjustments to raw census counts. In addition to a small adjustment to move the time reference from census day to mid-year, a total of 1.2 million was added in 1991 to represent those people missed by the census. The number of missing residents and their distribution within Britain relied on demographic analysis, since the Census Validation Survey had failed to identify the majority of those missed. While an undercount of 1.2 million represents only 2.2 per cent of residents over Great Britain as a whole, it was concentrated in certain age groups and areas; for example 20 per cent was added to the census count for men in their twenties across all cities in Britain. The third adjustment transferred students from their vacation address as measured in the census, to their term-time address as required by population estimates. Although the net, national, effect of transferring students to term-time address is small, the gross number of students in their teens and early twenties moved from one district to another is of the same order as under-enumeration at those ages (see Figure 1). These adjustments for local authorities have been described in detail elsewhere.1 While measurement of non-response was difficult for local authority areas, there was still less evidence on which to base the allocation of non-response for a district to small areas within it. ONS (then OPCS2) produced population estimates for wards in England and Wales by distributing the difference between census and population estimates for a district to each ward pro rata to the census count in each ward. These preliminary estimates, termed ‘even-spread’, were derived for the purpose of immediately making estimates of mortality rates for electoral wards.

When we ask if an adjustment is acceptable we are asking if you think its results are at least as plausible as other feasible adjustments. We are not asking you to say that it is itself definitely the best adjustment possible: there will usually be more than one acceptable adjustment. Please use your personal and professional judgement; we rely on your knowledge of the areas involved, and your understanding of what might have caused nonresponse in them, and where students live and come from. Many users were convinced that the required adjustments to the census were not distributed evenly between local areas. This would clearly be the case for the transfer of students to their term-time address around educational establishments. In addition, response rates were likely to vary within a district according to the difficulty of enumeration of each area, just as ONS and GRO(S) had estimated for districts themselves. However, the absence of direct evidence for the extent of census non-response locally, made it hard to justify specific adjustments to the census. The Estimating with Confidence project judged that adjustments would be valid if they were plausible, acceptable, and were consistent with the district estimates which incorporate evidence from the Census Validation Survey and demographic analysis. The project undertook wide consultation on alternatives with this aim.3 This article summarises that consultation and describes the method finally used by the Estimating with Confidence project to produce population estimates for electoral wards in England and Wales and postal sectors in Scotland. These areas are described as small areas unless qualified otherwise. The estimates are available for each five year age group to 85-89, and 90 and over, for males and females separately. They have been used in government and academic research, as described at the end of the article. The responses were in general very favourable to uneven distribution of non-response and students within a district. For example, The Estimating with Confidence adjustments are definitely to be preferred to the even-spread estimates, which are nonsensical in areas with concentrations of armed forces or students, and take no account of the socio-economic characteristics of an area in relation to under enumeration. There were nonetheless comments on anomalous areas which led to fine tuning of the population estimates. Finally, six adjustments to the census were made as in Table 1. Each is discussed here in turn, with attention to alternatives. C O N S U LTAT I O N A N D A LT E R N AT I V E S Consultation took place during 1994 through academic seminars, a steering group of local and central government staff and, most importantly, discussion with thirteen local authority staff in eight counties. These local demographers from planning, development and research functions, were not only familiar with census data and population estimates, but could also test results against their expectations by taking into account the characteristics of the local areas. They were provided with several alternative population estimates for the wards in their county and notes which stressed that: It is our hope that a single set of procedures for adjusting the 1991 census will be acceptable in all areas; your comments Table 16 Table In the discussion it was accepted that population estimates for the areas within a district should sum to the estimate made by ONS or GRO(S) for that district, at each age and sex. A nationally acceptable set of estimates would have been hard to achieve without this starting point. THE ADJUSTMENTS FOR STUDENTS The census, while counting students as resident at their vacation address, also asked their term-time address, and recorded them again at their term-time address as a visitor if present there on census night. However, a transfer of students directly from one address to another is not possible from census output. Instead the number of resident students counted by the census at a vacation Adjustments to small area census counts to derive a mid-1991 population Adjustment Indicator used to distribute the district adjustment to local areas Students removed from their home address area because they study elsewhere Student residents with term time address elsewhere, from census table S10. Separately for those aged under 18 and 18+, sex disaggregated according to table S37. Students added to their term-time address area Student non-residents with term time address at this address, from census table S10. Separately for those ages 15–17 and 18+, sex disaggregated according to table S37. For those aged under 15, often boarding pupils in preparatory schools.

All other non-response Imputed residents, from table S01 and Unemployed males aged 20–34, from table S08. Data modification Distributed equally to each local area. The small area census counts for each age and sex group are taken from local statistics table S02. The above adjustments to those counts and the derived populations are constrained to sum to the ONS and GRO(S) district adjustments for student residence, timing, armed forces non-response and other non-response, and to the ONS and GRO(S) district mid-1991 population estimates, at each age and sex. 32 O f f i c e f o r N a t i o n a l S t a t i s t i c s 8 89 0| | S u Wm i nmt ee rr 11 99 99 77 address which was not their term-time address was used as an indicator of the number of students who should be removed from an area for the population estimates. Similarly the number of student visitors at their term-time address was used as an indicator of the number of term-time students to be added to that area. These indicators determined the share of students removed and added out of the total for the district in which the small area was located, already estimated by ONS and GRO(S) for each age-sex group. The procedure is practical but approximate for various reasons. Conceptually, the district adjustment caters for students studying outside the district of their vacation address, and thus the procedure for small areas misses the moves of students from vacation to termtime address within a district. Such numbers are small in Britain compared with the moves between districts. Where student halls of residence were closed during the vacation at the time of the 1991 Census, the procedure outlined would underestimate the number of term-time students in the area. No solution was proposed to this problem, which suggests that the transfer of students should be rather more skewed than that which was made. Consultation highlighted that boarding schools of pupils under 16 required extra procedures. For these ages only, additional information was used on visitors in educational establishments, imputing an age structure for them from other census tables. The revised procedure gave better results in the two test counties with significant numbers of boarding school students. TIMING The timing adjustment for a district is the sum of the effects of ageing, births, deaths, and migration during the ten weeks between census day (21st April) and 30 June 1991 estimated by ONS and GRO(S). While indicators of births and deaths could feasibly have been sought for each small area, the small size of the adjustment did not justify the effort involved. The district timing adjustment at each age- and sex-group has been allocated to small areas pro rata to the number of residents in the area in that age- and sex-group counted in the census. No attempt was made to identify small areas where the timing adjustment would have been atypical due to very local demographic trends. ARMED FORCES NON-RESPONSE The ONS and GRO(S) estimates of the census non-response amongst armed forces personnel is based on reports from the Ministry of Defence, and indicates a wide range from under 10 per cent to over 50 per cent extra to the enumerated armed forces. This is consistent with troop movements temporarily leaving some bases, leading to major under-enumeration in the districts that contain them. Some of those consulted felt strongly that armed forces personnel on bases were more likely to be omitted from census counts than armed forces personnel in accommodation outside bases. For these reasons, the final local estimates make a distinction for districts whose armed forces non-response was more than 15 per cent of the estimated total (enumerated and missed). The excess above 15 per cent in these districts was distributed only to local areas with defence establishments within them. Up to this point, PP oo pp uu ll aa tt ii oo nn TT rr ee nn dd ss the district armed forces non-response was distributed according to the total number of armed forces in each area, whether on or off bases. The choice of 15 per cent is a little below the average 19 per cent for all districts with armed forces non-response, but it remains somewhat arbitrary. A L L OT H E R N O N - R E S P O N S E : AG E S 0 – 4 4 This was the largest source of adjustments, representing 0.99 million people missed from census tables. It caused the most discussion regarding its distribution to small areas within Districts. It was generally agreed that an even geographical spread of nonresponse was unlikely at these ages, but considerable discussion centred on eleven proposed indicators of this non-response. After implementing the options, the subsequent consultation was crucial to the choice between them. Three direct measures of non-response in small areas were proposed: registered births divided by infants under one enumerated by the census; registered claimants compared to census counts of unemployed; and sex ratios. Each gave a geographical pattern which was generally in accordance with the pattern expected by local demographers. However they could not be used because too often they gave rise to major anomalies. This was due to (a) the differences in definitions in the two data sources and (b) errors when allocating postcoded administrative records to small areas. The number of unmarried residents aged 20-34 was thought to indicate areas with many mobile, perhaps homeless, perhaps jobless, people who were most likely to be missed from the census count of residents. It was a significant predictor of district nonresponse.4 However the lack of variation between small areas in this indicator did not find acceptance with local demographers’ expectations of the non-response, especially in urban areas. Five other proposed indicators of non-response were rejected as not commanding sufficient plausibility. The number of male unemployed aged 20-34 is a summary indicator of the social conditions in an area. Such areas are again likely to have many mobile people – perhaps homeless or jobless – likely to be missed from census counts. In consultation it was felt to provide an acceptable and plausible distribution of nonresponse, with few extreme values. However, there was a concern that areas with low real coverage may have unrealistically low counts of unemployed in the census, leading to indicated nonresponse lower than merited. The number of imputed residents in the census counts – based on reports of the enumerator about households which did not return a census form – indicates uncooperative households, mobile people who are difficult to contact, homeless or transient households who feel a census about permanent residence is not relevant to them, and poor enumerators. Such areas are likely to also have the same kinds of people within responding households. These were the arguments for using the count of imputed records to estimate the location of missing people who were not imputed. Consultation found support for the indicator, but from some areas a scepticism about its skewness – high proportions of non-response were directed to a small number of wards within each district – and concerns in particular areas about armed forces bases, student areas and second homes which were felt to have wrongly high rates of imputation.

Thus the problem of imputed residents in holiday accommodation was raised by mainly rural areas where there was less undercount to allocate. Urban areas were less keen on indicators such as the number of unmarried young residents because it seemed to wrongly give too even a spread of undercount. Getting it right where large numbers were involved was felt to be a reasonable approach. • Large errors in either indicator would be dampened by the other. • The difference between the two indicators gives an indication of the uncertainty in estimating the population.5 The decision to combine the results for more than one indicator has several other advantages: Non-response at these ages was estimated to be very small by ONS and GRO(S) (see Figure 1). It was therefore distributed in the simplest way – pro rata to existing residents enumerated in each area. • The skewness of the imputation and the conservatism of the unemployed indicator balance each other out to some extent. 34 O f f i c e f o r N a t i o n a l On the other hand, the use of the mean of two indicators ensures a lower variance than if either had been used on its own. The results may under-estimate some extreme areas of non-response.

One would expect them to be at home to respond to enumerators’ calls, or at least evident sufficiently for them to be imputed on the basis of enumerators’ reports. A hypothesis that these were residents recently moved to institutions and counted there as visitors, is discounted by the small number of such visitors at institutions recorded by the census.3 It may be that very elderly residents were included by imputation, but with incorrect age; however there are no data to evaluate this hypothesis. With such lack of both evidence and plausible, accepted hypotheses, nonresponse among the very elderly was distributed pro-rata to existing residents enumerated in each area, as for non-response at ages 45-79. D ATA M O D I F I C AT I O N A final very small adjustment was required because each census count for an age-sex group in a small area has been randomly modified before publication by the addition of 1, 0, or -1 to protect Table 2 Examples of the construction of the population estimate from the census Males aged 20-24 in two wards of Bradford district Census count of residents Ilkley University 419 1,233 Adjustments for: Net student adjustment -68 +783 Timing +1 +2 0 0 (+31) (+48) +39 (+274) (+192) +233 0 0 EwC population estimate 391 2,250 Preliminary, even spread estimate 504 1,482 Armed forces non-response All other non-response (a) According to unemployment (b) According to imputed residents Mean, 1⁄2(a)+1⁄2(b) Modification Table 3 PP oo pp uu ll aa tt ii oo nn TT rr ee nn dd ss confidentiality of the stored census data. In order to maintain consistency with district estimates, the difference between the district (unmodified) census count and the sum of the small areas’ modified counts was distributed evenly between the areas in the district. EXAMPLE Table 2 gives an example of the construction of the population estimate for males aged 20-24 in two extreme wards of one district. The addition for timing and for data modification are small in both wards. The student adjustments add 783 residents to the population of University ward, but a deduction is made to the count in Ilkley ward, which is a prosperous area where many students have their parental home. No armed forces were estimated by ONS to be missed from this district, and thus no adjustment was made to any local area within the district. The non-response estimated by ONS for the district was distributed on the basis of unemployment and imputed residents, and the mean of two estimates applied. In this case the two estimates both indicated a relatively large undercount in University ward but only a small one in Ilkley ward. The highly skewed distribution of student residences and to a lesser but significant extent that of nonresponse, contribute to a population estimate overall 82 per cent higher than the census count for University ward, but 7 per cent lower for Ilkley. In contrast the preliminary even-spread estimate produces a population estimate 20.2 per cent higher than the census count for both wards, the same as the difference estimated by ONS for Bradford district as a whole for males aged 20-24. EXTREME ADJUSTMENTS Table 3 shows the district and small area where the most extreme adjustments were made, for each adjustment in turn. The transfer of students and the non-response among armed forces are more concentrated geographically than non-response. Both produce extreme adjustments that double the population as counted by the census. In the case of one Oxford ward the transfer of students increases the census count of residents nearly five times. In comparison, the greatest impact of estimated non-response in a single ward is to increase the census by 14 per cent. Table 4 shows the district and small area with largest total adjustment, within each county (and region in Scotland) as constituted in 1991. These are the areas where use of the census count as a population estimate would be most misleading.

Only in Gwent and the Scottish Isles was ‘other non-response’ more extreme than armed forces non-response or the student transfer. THE RELATIONSHIP BETWEEN EACH ADJUSTMENT Table 5 shows the composition of the adjustments, averaged across all small areas of Britain. The average census population of 5,222 is augmented by 4 between census day and mid-year 1991, by 6 students (reflecting the balance of students whose home residence is outside Britain), and by an undercount of 4 armed forces and 110 other residents. Of the 10,512 small areas, in well over two thirds the biggest adjustment was that due to non-response other than armed forces, adding an average of 133 residents to the area. In these small areas, the other adjustments tended to be small. Figure 2 The relationship between the student transfer and non-response is of interest. The areas receiving a large transfer of students, mainly around higher education institutions, include areas of very high non-response, higher on average than the wards where nonresponse is the main adjustment. Student accommodation is often within very poor inner city areas with high unemployment and households that are difficult to enumerate. It is also likely that some households imputed to have residents in the census were wrongly imputed because they were entirely made up of students. This could lead to an over-estimated population for the small area. The estimates are likely to slightly under-estimate the population around some student halls of residence that were not occupied on census day, and over-estimate the population around areas of other student accommodation. For more than one fifth of small areas the biggest adjustment was the subtraction of students with a term-time address elsewhere. These were mainly outside city areas, with relatively small populations. The eleven areas where the adjustment for timing was most important are mainly in the City of London, with small populations and very atypical age structures. Non-response estimated for socially extreme areas NON-RESPONSE AND SOCIAL COMPOSITION Figure 2 shows the non-response as a percentage of the population for those areas that are the 5 per cent most extreme of all ten thousand small areas in Britain, according to several measures of social composition. It shows that if the spatial distribution of nonresponse estimated by ONS, GRO(S) and in this article is correct, then areas associated with poorer incomes and housing conditions have approximately twice the non-response found in the average area. This does not show the differential under-enumeration for people with each characteristic which is likely to be still more than twice in most cases6.

Figure 3(b) shows that the population estimates for the total population and for age-groups under 45 were substantially different from the ONS preliminary estimates for wards. Only in the older age-groups did the population estimates allocate adjustments with the same ‘even-spread’ approach and the same results as in the even-spread estimates. A VA I L A B I L I T Y The population estimates described in this article are available from the Estimating with Confidence project.7 Each adjustment as well as the population estimate, for each age and sex and small area within a county are provided on disc. The estimates and adjustments are also available at the Data Archive at Essex University. Academic users have on-line access via the MIDAS service based at the University of Manchester. The Estimating with Confidence project can also provide adjusted counts for each enumeration district within a county, and for 38 O f f i c e f o r N a t i o n a l The evidence that census response rates are not constant across areas is sufficiently compelling to demand that the census is not used as an estimate of the complete population in local areas without adjustment appropriate to the characteristics of the local area. However the equal lack of evidence about the response rates in each area demanded that these adjustments were plausible and acceptable to those with local knowledge but could not be validated against any external measure. The methods of adjusting 1991 census data to derive a population estimate for areas within districts have been as approximate as they have been necessary. In specific cases, local authorities may be able to improve on the estimates through local data sources on particular groups of students or armed forces. The estimates described in this article provide a generally acceptable, generally applicable set of population figures for areas within districts, that are consistent with government population estimates for those districts. The research required to devise and agree these population estimates, as well as the unknown biases and degree of approximation involved, will be avoided in future if census procedures can measure the characteristics of census nonrespondents in sufficient detail. The feasibility of this measurement, and of adjusting the 2001 Census output for nonresponse before it is published, are currently under consideration by ONS.

At working ages, 15 to 64, there was very little difference in breast cancer incidence between women in non-manual and manual classes. At older ages the incidence was INTRODUCTION higher in women in non-manual classes than in those in manual classes. Cervical cancer incidence was considerably higher among younger women in manual than in non-manual classes and these differences were greatest in 1986-89. Among both younger and older men and women, strong class differentials in the incidence of lung cancer were evident in 1986-89. These findings indicate the need to target prevention strategies sensitively and to ensure equitable access to services. In England, the Health of the Nation1 initiative aims to reduce the incidence of specific cancers within the next five to ten years (Box 1). Most cancers are associated with strong socio-economic gradients2, 3, 4 and it is important to monitor these differences if reductions in incidence and mortality are to be achieved. Measuring the incidence of cancers with a preventable component, such as lung, cervical and malignant melanoma of the skin, can help public health planners target prevention strategies sensitively. For cancers such as breast, with no established prevention strategy, differences in incidence among social groups have implications for the provision and monitoring of services such as screening programmes. Early detection of breast cancer is important if chances of survival are to be equitable across all social groups. With twenty years of follow-up, the Longitudinal Study provides an unique opportunity to measure socio-economic differences in cancer incidence. The Longitudinal Study comprises a one per cent representative sample of the population of England and Wales. Cancer registrations are linked into the study and people are classified by their socio-economic characteristics at a census. Previous work on cancer incidence by social class was based on the period 1971-1981.4 This article uses cancer registrations up to 1989 and focuses on social class patterns in the incidence of the Health of the Nation cancers (Box 1). METHOD The ONS Longitudinal Study is a record linkage study of an approximately one per cent representative sample of the population of England and Wales (about 550,000 people). The initial sample, drawn from the 1971 Census, is continually updated to include new 40 O f f i c e f o r N a t i o n a l S t a t i s t i c s 8 89 0| | S u Wm i nmt ee rr 11 99 99 77 members through birth and immigration. Subsequent census and vital event information is linked to the study through the National Health Service Central Register. Full details of the linkage procedures are described elsewhere.5 The main analysis is based on the 1971 Cohort (Box 2) for whom longer follow-up makes trend analyses feasible. Longitudinal Study members were assigned to a social class according to their occupation at the 1971 Census: Social Class I (professional), II (intermediate), IIIN (skilled non-manual), IIIM (skilled manual), IV (partly skilled) or V (unskilled). Because of small numbers of cases of lung and cervical cancers among women, the classes have been aggregated into non-manual (I,II,IIIN) and manual (IIIM,IV,V). For similar reasons Social Classes I and II were aggregated as were Social Classes IV and V for the leading cancers, breast among women and lung among men. Anyone whose occupation was inadequately described or not stated, or who was recorded as permanently sick or otherwise economically inactive was categorised as ‘Unclassified’. Women were classified according to their partner’s occupation or, if this was not available, by their own. Cancer registrations for the period 1976-89 were examined. As is now conventional for social class analysis of longitudinal data, the first five years of follow-up were excluded because of the potential effects of health selection (Box 3). A subsidiary analysis was carried out using social class at the 1981 Census (Box 2). Again, to reduce the effects of health selection, the follow-up period for these people was from 1986-89. With this analysis we compare the social class patterns for the period 1986-89 using the more recent measure of social class from the 1981 Census. Incidence rates for each social class category were standardised by the direct method using the World Health Organisation European Standard Population, and derived for breast, lung, and cervical cancers (ICD 174, 162 and 180 respectively). Limited findings for malignant melanoma of the skin (ICD 172) are also presented. Non–melanotic skin cancer was excluded due to the unreliability of its registration.6 In the 1971 Cohort, the age-specific incidence rates were calculated using cancer registrations and person years at risk (Box 4) for each of three time periods (1976-1980, 1981-1985, 1986-1989). In the 1981 Cohort, the age-specific rates refer to 1986-89. Rate ratios (RR) for two age-groups (15-64 in the 1971 Cohort/16-64 in the 1981 Cohort and 65 years and over) were derived using the largest class (IIIM) as the baseline category (RR=1). Ratios for manual versus non-manual social class categories were also derived (RR=1 for the non-manual classes). Comparison of ratio measures between social classes are affected by the differences in class sizes. Smaller classes at the extremes are likely to lead to larger ratios when comparing the top with the bottom of the hierarchy. Conversely, the manual/non-manual ratio is likely to underestimate class differences as it ignores the differences between individual classes. The index of inequality avoids this problem as it adjusts for the different sizes of the classes.7 Social class, based on all six levels, within each five yearage band was assigned a value between zero and one according to the proportion of subjects above the midpoint of each class. For example, men aged 40-44 in Social Class I comprised 6 per cent and were assigned a value of 0.03, which is the proportion above the midpoint of that class; those in the next class comprised an additional 22 per cent and were assigned a value of 0.6+0.22/ 2=0.17. This indicator of social position was then related to cancer incidence rates using regression analysis. In the models, age was fitted in five year age groups. The further the index of inequality from 1.00, the greater the differentials across the social classes.

Cervical cancer - reduce the incidence of invasive cervical cancer by at least 20 per cent by the year 2000. Skin cancer - halt the year-on-year increase in the incidence of skin cancer by 2005. Box Two The 1971 Cohort comprises all persons present at the 1971 Census and traced in the National Health Service Central Register. In this analysis, they were aged 15 and over at the start of study, classified by their occupation details at the 1971 Census and followed-up to the end of 1989. The 1981 Cohort comprises all persons present at the 1981 Census and traced in the National Health Service Central Register. They include mainly those in the 1971 Cohort who survived the first ten years of follow-up but also a small proportion of immigrants who entered England and Wales between censuses. The 1981 Cohort were aged 16 and over at the 1981 Census, classified by their information at that census and followed up to the end of 1989. Box Three In a longitudinal study, health selection may affect mortality differentials in the early period of follow-up. Health selection refers to the process whereby individuals are included or excluded from a group because of their health status. Employed individuals are generally assigned to a social class. They also tend to be healthier than those out of work. The effects of health selection on mortality differences by social class wear off with increased follow-up. Most of the effect disappears after the first five years.5 Box Four In the Longitudinal Study, we can calculate the exact fraction of a year in which each individual is at risk of death after adjusting for people leaving and entering the study. This cumulative total is known as the person years at risk and is used to calculate death rates per 100 000 person years at risk.

The absolute level of incidence was considerably greater at older ages for breast and lung cancers, but for cervical cancer it was similar in the two age groups. Breast cancer was the most common cancer for women in both age groups, accounting for 33 per cent of all cancers in those under 65, and 22 per cent at older ages. Over the entire follow-up period (1976-89), the incidence in women aged under 65 years was lowest in Social Classes IV/V but differences between classes were not statistically significant (Table 1). At age 65 and over, incidence was highest in women in Social Classes I/II and IIIN, resulting in At working ages, the incidence of lung and cervical cancers was higher in manual than non-manual classes. For women under 65 years, the incidence of lung cancer in women in manual classes was 72 per cent higher than those in non-manual classes and that of cervical cancer was 61 per cent higher. These relative differences narrowed at older ages. Small numbers of malignant melanoma preclude firm conclusions but there is a consistent pattern of higher incidence in non-manual than manual classes in both age groups. Men Lung cancer was the leading cancer for men, accounting for 31 per cent of all cancers.

Figure 1 shows the corresponding results using the index of inequality which compares the top with the bottom of the social class hierarchy, adjusted for differences in class sizes. 60 Index of inequality (relative risk and 95% confidence intervals), women, by age and follow-up period. 1971 Longitudinal Study Cohort GB rate 50 Among women aged under 65, both the non-manual/manual ratios and relative index of inequality indicate no statistically significant relationship between breast cancer incidence and social class in any of the three time periods. The pattern is not consistent across the three time periods. In the first two periods incidence appeared higher in non-manual than manual classes, but in 1986-89, the incidence appeared higher in manual classes. At older ages, the pattern is consistent in all three time periods with generally higher incidence in non-manual than manual classes. 40 30 For lung cancer, the rate ratios based on manual/non-manual classes increased over time among women aged under 65. In 198689, both the manual/non-manual rate ratio and the relative index of inequality indicate large class differentials. At older ages, both measures indicate that lung cancer incidence was higher in manual classes only from 1981 onwards and that social class differentials increased then reduced. 20 10 The incidence of cervical cancer was consistently higher in manual than non-manual classes at working ages in every time period. In 1986-89, the incidence of cervical cancer in manual classes was more than twice that of non-manual classes. The index of inequality indicates even larger class differences. At older ages, the manual/non-manual ratio indicates increasing class differences but this trend was not consistent with that of the relative index of inequality. Both measures, however, show large social class differences in 1986-89. 0 England Wales Scotland countries of Great Britain North North Yorkshire East West East London South South East West East West and the Midlands Midlands Humber regions of England Men For men in both age groups, there were strong social class gradients in lung cancer incidence in each time period. Class differences were larger at working ages. In 1986-89, lung cancer incidence in Social Class I/II was 92 per cent higher than that in Social Class IV/V. Large class differences can also be seen in Figure 2 using the index of inequality. I n c i d e n c e r a t e s b y s o c i a l c l a s s ov e r t i m e Women Table 4 shows incidence rates and percentage change in rates over the same time periods. Percentage changes are also shown in Figure 3. At working ages, overall incidence of breast cancer did not change significantly. A small rise can be seen between 1981-85 and 1986-89. Between 1981-85 and 1986-89 the rates for women in Social Classes IIIN, IIIM and IV/V rose but that of Social Class I/II declined, resulting in the apparent change in relative differences between women in non-manual and manual social classes noted above. At older ages, overall incidence fell and the decline was consistent for women in non-manual classes but not for those in manual classes. In spite of this decline in non-manual classes, however, incidence rates remained higher than those of older women in manual classes in all three time periods. 44 O f f i c e f o r N a t i o n a l At working ages, overall lung cancer incidence remained at similar levels over the three time periods. Women in non-manual classes experienced declines which account for the persistent large class differentials observed above. At older ages overall incidence rose over time, but by class this trend is not consistent. Women in nonmanual classes experienced a fall followed by a rise whereas among women in manual classes, the incidence rose and remained high. In both age groups, overall incidence of cervical cancer did not change significantly across the three time periods. At working ages, incidence in women in non-manual classes declined between 198185 and 1986-89 but that of women in manual classes remained at a similar level. At older ages, both non-manual and manual classes showed declines in the 1980s but the decline was larger in non- S t a t i s t i c s 8 89 0| | S u Wm i nmt ee rr 11 99 99 77 manual classes. This accounted for the large social class differentials in 1986-89. Men Table 4 and Figure 4 show that the overall incidence of lung cancer fell among men aged under 65 but the proportionate declines in non-manual and manual classes were similar, accounting for the persistence of strong class gradients in each time period. At older ages, in 1986-89, Classes I/II and IV/V showed declines but Classes IIIN and IIIM showed a rise in incidence. The larger decline for Class I/II compared with Class IV/V, however, contributed to the persistent overall class differentials. Social class in 1981 and cancer incidence for the period 1986-89 Women Table 5 shows incidence rates for the period 1986-89 using social class from the 1981 Census for all those present at that census (1981 Census Cohort - see Box 2). The comparable rate ratios based on social class in 1971 are shown in parentheses. In 198689, there was no clear class gradient for breast cancer by the measurement of social class in 1981. By social class in 1971, the incidence at working ages appeared lowest in Class I/II and highest in Class IIIM, resulting in generally higher incidence in manual than non-manual classes. By class in 1981, however, the incidence was highest in Classes I/II and IV/V so that the overall difference between non-manual and manual classes is small. At older ages, class in 1971 shows higher incidence in non-manual women but again by the later measurement in 1981, the difference between non-manual and manual classes is very small. The smaller difference in breast cancer incidence between nonmanual and manual classes in the 1981 Cohort compared with the 1971 Cohort, may be due to the continuing effects of health selection (Box 3). ‘Unclassified’ people are more likely to belong to a manual than a non-manual class. 8 In the 1981 Cohort, ‘Unclassified’ women of working ages showed the highest incidence and it is likely that their exclusion contributed to an underestimation of incidence in manual classes. Similarly, at older ages ‘Unclassified’ women showed lowest incidence which would have meant that the incidence in the manual class was overestimated. Additionally, at older ages it was more difficult to allocate women to a social class. The incidence of lung and cervical cancers remained considerably higher among women in manual classes in both age groups by class Figure 2 Index of inequality (relative risk and 95% confidence intervals), men, by age and follow-up period. 1971 Longitudinal Study Cohort TT rr ee nn dd ss in 1981. At working ages, the incidence of lung cancer was 69 per cent and that of cervical 77 per cent higher in manual than in nonmanual classes. Men Among men, a steep class gradient for lung cancer persisted with the later measurement of class in 1981. At working ages, the incidence in Social Class IV/V was twice that of Social Class I/II. At older ages the differences between these classes remained large, at 82 per cent. DISCUSSION Even in a study as large as the Longitudinal Study, the number of cases of the most common cancers is small.

Figure 4 Percentage change in standardised rates between time periods, men. 1971 Longitudinal Study Cohort Percentage Breast cancer was the most common cancer in women of all ages and from the national cancer registration data, its incidence is known to have risen in the 1980s.9 The 1971 Cohort in the Longitudinal Study showed a small rise in incidence in women under 65 but a decline in women aged over 65. Previous analysis of Longitudinal Study data showed breast cancer incidence to be higher among more affluent women.3 Over the entire follow-up period there was little difference between the social classes in incidence in women of working ages. By time period, however, there appeared to be a change in the pattern from higher incidence in women in non-manual classes in 1976-85 to higher incidence in those in manual classes in 1986-89. Longer follow-up is needed to confirm these trends. Recent analyses indicated a corresponding change in mortality trends from lower mortality of women in manual classes compared with those in non-manual classes to no significant difference in 1986-92.10 Work in the United States has shown a change in social class patterns among white women, with higher incidence in the manual classes than in the professional classes.11 At older ages incidence was consistently higher among women in non-manual classes. As registration coverage is generally high and has been reported at around the same level since 197111 discrepancies in coverage are unlikely to be biased by social class. The NHS breast screening programme began in 1988 and with follow-up only to the end of 1989, the rise in incidence among younger women in manual social classes cannot readily be explained by increased uptake of screening. The risk of breast cancer increases with age at first pregnancy.12 It is possible that the rise in incidence could be influenced by delayed childbirth, a pattern established earlier among women in non-manual classes.13 An association has also been found between adverse life events and 60 GB percentage 50 40 30 20 10 0 Rural Remoter Established New and Amenity Rural Manufact- Developuring ing Areas Fringe Mixed Urban Coast Established Growth Most Coalfields Manufact- Ports Education West and Service Areas Prosperous uring and Centres Inner Country Centres Centres Industry and Outer London Resorts London breast cancer.14 In the 1980s, women in manual classes were more likely to face the added stresses of being unemployed than those in non-manual classes.15 Over the entire follow-up period, the incidence of cervical cancer showed a social class differential for women under 65. In both age groups, the relationship between social class and incidence of cervical cancer was strongest in the most recent period, 1986-89. The risk of cervical cancer is strongly influenced by sexual behaviour, parity, age at first pregnancy and smoking.16 Screening for cervical cancer was well established before the follow-up period of this study although there were occasional publicity campaigns to encourage uptake and promote healthy behaviour.

These findings highlight the need to continue to target preventive strategies and to encourage the uptake of screening services by women in manual classes. The social class gradients for lung cancer are well established 4,10 and our findings confirm the persistence of these class differences. Smoking is undisputedly the single most important cause of lung cancer. The changing pattern of lung cancer among older women, with incidence higher in non-manual classes in the earliest period but higher in manual classes in the 1980s, possibly reflects changes in smoking patterns between cohorts. Declines in smoking levels occurred later for women compared with men and social differentiation only became apparent in the late 1960s.17 Recent data has shown that men and women in Social Class V are almost four times more likely to smoke than those in Social Class I. 18,19 Since 1972 there has been a steady decrease in the proportions of men smoking although the numbers are consistently higher among men in manual classes. Over the same period the number of women smoking fell steadily in the non-manual classes but a fall in the manual classes did not begin until 1982.18 Although smoking rates have fallen in the adult population, recent evidence indicates a rise among teenagers, particularly girls. 20 This has implications for future trends in lung cancer. The poor prognosis of this cancer makes it important to encourage anti-smoking strategies. The incidence of malignant melanoma of the skin was higher among men and women in non-manual classes at both working and older ages, suggesting greater exposure to sunshine among these people. Women had higher rates than men. The higher incidence at older ages is consistent with the suggestion that the risk of this cancer is influenced by accumulated exposure to the rays of the sun.1 Although malignant melanoma of the skin accounts for a relatively small number of cancers they are potentially preventable. Wide publicity is currently being given to ways of protecting against this cancer and the results of these campaigns should be monitored. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. These findings have important implications for policy makers and clinicians. If the Health of the Nation targets for cancer are to be achieved, the need remains for coherent strategies for prevention and early detection. Underlying issues of inequalities must be addressed to prevent social class differences in exposure to risk factors. For cancers with a preventable component, such as those of the lung and cervix, targeting primary intervention strategies sensitively is important for the control of risk factors. For cancers such as breast, with no known prevention strategy, it is important to encourage self-awareness as well as ensuring equitable provision of services. 19. 20. References 1. 2. 3. 4. 5. 6. 7.

Key Findings Breast cancer was the most common cancer for women at all ages but the incidence of disease was greater at older ages. Over the entire follow-up period, there was very little difference in incidence between younger (1564) women in non-manual and manual classes. At older ages (65+), the rates were consistently higher among non-manual women. The overall incidence in cervical cancer was similar at working and older ages. At working ages the incidence was consistently higher for women in manual than nonmanual classes, and was more than double that of nonmanual classes in 1986-89. Lung cancer is predominantly a disease of older ages. The incidence was consistently higher in men than in women. Among women and men of working ages, the incidence was higher among manual classes. By 1986-89, these differences were two-fold among women. A greater decline in lung cancer incidence among those in non-manual classes led to the non-manual/manual differences over time. f o r N a t i o n a l S t a t i s t i c s 47 9 0 | 48 Wi n t e r 1 9 9 7 9 0 | Wi n t e r 1 9 9 7 P o p u l a t i o n T r e n d s Tables table page 1 50 2 51 3 4 52 53 5 54 6 7 55 57 Constituent countries of United Kingdom 8 58 England and Wales 9 60 England and Wales 10 60 England and Wales 11 61 England and Wales 12 62 Constituent countries of United Kingdom 13 63 England and Wales England and Wales England and Wales 14 15 16 64 65 66 England and Wales 17 68 United Kingdom United Kingdom United Kingdom 18 19 20 69 70 71 United Kingdom 21 72 England and Wales 22 73 England and Wales England and Wales 23 24 74 75 Population International National Subnational Subnational Components of population change Age and sex Age, sex and marital status Selected countries Constituent countries of United Kingdom Standard regions and metropolitan countries of England Health regions of England Constituent countries of United Kingdom Constituent countries of United Kingdom England and Wales Vital statistics Summary Live births Age of mother Outside marriage: age of mother and type of registration Inside marriage: age of mother, marital status, and birth order Conceptions Age of women at conception Expectation of life (in years) at birth and selected ages Deaths Age and sex Subnational Selected causes and sex Abortions Marital status, age, and gestation weeks International migration Age and sex Country of last or next residence Citizenship Internal migration Movements within the United Kingdom Marriage and divorce First marriage: age and sex Remarriages: age, sex and previous marital status Divorce: age and sex O f f i c e f o r N a t i o n a l S t a t i s t i c s 49 P o p u l a t i o n Table 1 Year 9 0 | T r e n d s Wi n t e r 1 9 9 7 Population and vital rates: international United Kingdom (1) Denmark (2) France (2) 4,963 5,073 5,122 5,121 5,154 5,189 5,206 5,233 51,251 52,909 54,182 55,547 57,055 57,665 57,915 58,146 61,302 61,531 61,685 61,068 64,105 65,514 65,873 4.4 1.9 — 3.3 3.5 3.3 5.2 6.5 4.8 5.0 5.5 5.1 4.3 4.0 Live birth rate (per 1,000 per annum) 1971–75 14.1 13.5 1976–80 12.5 12.4 1981–85 12.9 12.0 1991 13.7 12.6 1993 13.1 12.0 1994 12.9 11.5 1995 12.5 11.4 1996 12.5‡ 14.6 12.0 10.2 12.5 13.0 13.4 13.4 Death rate (per 1,000 per annum) 1971–75 11.8 1976–80 11.9 1981–85 11.7 1991 11.3 1993 11.3 1994 10.7 1995 11.0‡ 12.1 11.6 11.4 10.5 10.7 10.4 10.5 10.1 10.5 11.1 11.6 12.1 11.7 12.1‡ European Union (3) Sweden (2) USSR† (2) Australia (1) Canada (4) New Zealand (5) China (5) India (6) Japan (7) USA (1) 305,391 313,034 319,095 322,103 328,946 332,287 333,538 8,115 8,236 8,320 8,370 8,617 8,719 8,781 8,827 243,891 255,605 267,722 280,237 291,049‡ 13,067 14,033 14,923 16,018 17,292 17,662‡ 17,843‡ 21,568 22,993 23,342 25,353 27,000 28,755‡ 29,248‡ 2,899 3,163 3,195 3,317 3,450 3,505‡ 3,493‡ 852,290 937,170 1,008,460 1,086,551 1,170,697 1,196,360‡ 1,208,842‡ 551,311 617,248 675,185 766,135 843,931 901,459‡ 918,570‡ 105,145 113,094 117,902 121,672 124,043 123,653‡ 124,961‡ 207,661 218,035 229,958 240,680 252,688 258,245‡ 260,651‡ 18.2 2.0 7.6 –10.4 26.7 –3.4 Population** (thousands) 1971 55,928 1976 56,216 1981 56,352 1986 56,852 1991 57,808 1993 58,191 1994 58,395 1995 58,606 1996 58,801 Belgium (2) 9,672 9,811 9,859 9,862 10,005 10,084 10,116 10,137 Population changes (per 1,000 per annum) 1971–76 1.0 2.9 1976–81 0.5 1.0 1981–86 1.8 0.1 1991–92 3.4 4.1 1992–93 3.2 3.9 1993–94 3.5 3.2 1994–95 3.6 2.1 1995–96 3.3 Year Spain (2) Population** (thousands) 1971 34,190 1976 35,937 1981 37,756 1986 38,627 1991 39,025 1993 39,083 1994 39,143 1995 39,210 Population changes (per 1,000 per annum) 1971–76 10.2 5.0 1976–81 10.1 3.8 1981–86 4.6 2.2 1991–92 1.5 5.7 1992–93 –0.1 4.4 1993–94 1.5 3.8 1994–95 1.7 Germany (Fed.

Notes: 1. Rates for the most recent quarters will be particularly subject to revision, even when standard detail is given, as they are based on provisional numbers or on estimates derived from events registered in the period. 2. Deaths for England and Wales represent the number of deaths registered in each year, except for 1993 and 1994 figures which represent the numbers of deaths occurring each year. 3. The marriage and divorce rates for 1991 onwards differ in part from those previously published because of a revision of the denominators. 58 O f f i c e f o r N a t i o n a l S t a t i s t i c s 9 0 |

ONS has produced a publication containing details of the effect of this Revision (Mortality statistics: comparison of 8th and 9th revision of the International Classification of Diseases, 1978 (sample), Series DH1 no.10). † Per 100,000 population. ‡ Provisional. Notes: 1. Between 1 January 1984 and 31 December 1992, ONS applied the International Classification of Diseases Selection Rule 3 in the coding of deaths where terminal events and other ‘modes of dying’, such as cardiac arrest, cardiac failure, certain thromboembolic disorders, and unspecified pneumonia and bronchopneumonia, were stated by the certifier to be the underlying cause of death and other major pathology appeared on the certificate. In these cases Rule 3 allows the terminal event to be considered a direct sequel to the major pathology and that primary condition was selected as the underlying cause of death. Prior to 1984 and from 1993 onwards, such certificates are coded to the terminal event. Further details may be found in the annual volumes Mortality statistics: cause 1984, Series DH2 no. 11, and Mortality statistics: cause 1993 (revised) and 1994, Series DH2 no 21. 2. On 1 January 1986 a new certificate for deaths within the first 28 days of life was introduced. It is not possible to assign one underlying cause of death from this certificate. The ‘cause’ figures for 1986 onwards therefore exclude deaths at ages under 28 days. 3.

Table 20 was changed in Population Trends 70 (see page 61 of that issue for details) Population the estimated and projected populations of an area include all those usually resident in the area, whatever their nationality. Members of HM forces stationed outside the United Kingdom are excluded. Students are taken to be resident at their term-time addresses. Figures for the United Kingdom do not include the population of the Channel Islands or the Isle of Man. The population estimated for mid-1991 onwards are final figures based on the 1991 Census of Population with allowance for subsequent births, deaths and migration. Population estimates for the years 1982-1990 have been revised, to give a smooth series consistent with both 1981 and 1991 Census results. Due to definitional changes, there are minor discontinuities for Scotland and Northern Ireland between the figures for 1971 and earlier years. At the United Kingdom and Great Britain levels these discontinuities are negligible. Live births For England and Wales, figures relate to numbers occurring in a period; for Scotland and Northern Ireland, figures relate to those registered in a period. See also Note on page 63 of Population Trends 67. Perinatal mortality On October 1992 the legal definition of a stillbirth was changed, from baby born dead after 28 completed weeks gestation of more, to one born dead after 24 completed weeks of gestation or more. Expectation of life The life tables on which these expectations are based use current death rates to describe mortality levels for each year. Each individual year shown is based on a three year period, so that for instance 1986 represents 1985-87. More details may be found in Population Trends 60, page 23. Pensionable ages Age analyses of the form 45-64/59 or 65/60-74 indicate age groups terminating at or beginning with the state pensionable age, 65 for men, 60 for women. Deaths Figures represent the numbers of deaths registered in each year, except for 1993 and 1994, which represent the numbers of deaths occurring in each year. See also Note on page 63 of Population Trends 67. Abortions Figures relate to numbers occurring in a period. Migration Figures in Tables 18-20 are derived from the International Passenger Survey (IPS), a sample survey of all passengers travelling through major air and seaports of the United Kingdom. Routes to and from the Irish Republic are excluded. Migration between the Channel Islands or the Isle of Man and the rest of the world was previously included in the total migration to the United Kingdom. From 1988 this has been excluded. It is highly likely that the IPD data also exclude persons seeking asylum after entering the country and short-term visitors granted extensions of stay, for example as students or on the basis of marriage. After taking account of persons leaving the UK for a short-term period who stayed overseas for periods longer that originally intended, the adjustment needed to net migration ranges from about 10 thousand in 1981 to 50 thousand in the latest year available. A migrant into the United Kingdom is defined in these tables as a passenger entering the United Kingdom with the declared intention of residing here for at least a year having lived abroad for at least a year; and vice versa for a migrant from the United Kingdom. Old Commonwealth is defined as Australia, Canada, New Zealand and South Africa, New Commonwealth is defined as all other Commonwealth countries. Middle East is defined as Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, the United Arab Emirates, and Yemen. Figures in Table 21 are based on the movement of NHS doctors’ patients between Family Health Services Authorities (FHSAs) in England and Wales, and Area Health Boards in Scotland, and Northern Ireland. Calendar year and mid-year figures have been adjusted to take account of differences in recorded cross-border flows between England and Wales, Scotland and Northern Ireland; quarterly figures have not been adjusted. The NHS Central Register (NHSCR) at Southport was computerised in early 1991, prior to which a three month time lag was assumed between a person moving and their re-registration with an NHS doctor being processed onto the NHSCR. Since computerisation, estimates of internal migration are based on the date of acceptance of the new patient by the FHSA (not previously available), and a one month time lag assumed. Marriages and divorces Work is in progress on finalising the corresponding 1991 population estimates in the light of the 1991 Census and 76 O f f i c e f o r N a t i o n a l S t a t i s t i c s 9 0 | Wi n t e r 1 9 9 7 P o p u l a t i o n T r e n d s Notes to Tables continued other data sources. Once this is done, retrospective revisions to the estimates from 1981 and 1991 may be necessary. Until then, estimates (and the marriage and divorce rates derived from them) from 1982 onward should be regarded as provisional. Marriages are those according to date of solemnisation. Divorces are those according to date of decree absolute, and the term ‘divorces’ includes decrees of nullity. conducted by the Social Survey Division of ONS. Rounding All figures are rounded independently; constituent parts may not add to totals. Generally numbers and rates per 1,000 population are rounded to 1 decimal place (eg. 123.4); where appropriate, for small figures (below 10.0), 2 decimal places are given. Figures which are provisional or estimated are given in less detail (eg. 123 or 7.6 respectively) if their reliability does not justify giving the standard amount of detail. Where, for some other reason, figures need to be treated with particular caution, an explanation is given as a footnote. Standard regions Figures refer to regions of England as constituted after local government reorganisation on 1 April 1974. The regions, defined in terms of the new counties, were listed in Population Trends 31, page 27. Latest figures Figures for the latest quarters and years may be provisional (see note above on rounding) and will be updated in future issues when later information becomes available. Where figures are not yet available, cells are left blank. Population estimates and rates based on them may be revised in the light of results from future censuses of populations. Health regions Figures refer to health regions of England as constituted on 1 April 1982 unless otherwise stated.The regions, defined in terms of the new district health authorities, as at 1 April 1982, were listed in Population Trends 31, page 28.
