Despite this there is considerable misunderstanding of the nature, scale, location and implications of population ageing in Australia. This is even the case in the aged care sector which is to be so crucially impacted by the ageing of the population. The aim of this appendix is to summarise the basic dimensions of the growth of Australia’s older population over the next two decades. The note will use the most recent Australian Bureau of Statistics (ABS, 2013a) population projections. It must be stressed, however, that anticipating change of older populations does not involve ‘crystal ball gazing’. There is a very high degree of certainty around projections of their numbers over the next three decades and they can be used with a high degree of confidence. This is because Australia’s older population of the 2020s and 2030s is already in Australia but are currently aged in their 40s and 50s. We not only know their numbers but also where they live and their economic and social characteristics. This can provide us with a clear window through which to view the size and characteristics of Australia’s future older population. Anticipating change in the numbers, characteristics and distribution of Australia’s older population is fundamental to planning the efficient and equitable provision of both residential aged care and home care. There are considerable lead-up times required, especially in the residential care sector as well as massive investments required to meet the inevitable increase in demand. Accordingly it is crucial that there is a full analysis of the details of the numbers of people who will need these services, their characteristics which will influence the nature of this demand, and where they live which will shape the location of 1 Demographic ageing of a population occurs when the proportion of the total population in the older age groups (usually 65+) increases. Currently all global populations are ageing, although the rate varies greatly between countries (United Nations, 2013). -2- future demand. It is argued here that the projections currently available, while useful, need to be enhanced through more detailed and nuanced future scenario development. This will provide greater certainty in the scale, nature and timing of expansion of both residential care and home care services. This paper summarises the current state of knowledge on these issues. There are four demographic aspects of the ageing of Australia’s population over the next two decades: The numbers of older people will increase rapidly because the ‘shockwave’ of baby boomers will all move past age 65. Accordingly the median ABS projections (ABS, 2013a) anticipate the numbers aged 65+ in Australia will increased by 84.8 percent from 3.1 million to 5.7 million between 2011 and 2031. The proportion that the older (65+) population will make up of the total population will increase from 13.8 percent in 2011 to 18.7 percent in 2031. This raises issues of worsening ratios between the working and non-working population and the effects of intergenerational transfers. The third dimension of population ageing in Australia is one which is often overlooked and relates to their characteristics. They are quite different to earlier generations entering the retirement stage of the life cycle – economically, socially, and in their values, attitudes, expectations and, most importantly, their health. This is because each cohort lives through quite different economic, social and cultural conditions, and have different sets of education, world experience, etc. Baby boomers differ in a myriad of ways from the previous generation of older people and this will also have a major impact on the nature of the care and residential arrangements which they need, seek, prefer and can pay for. -3- Finally, the geography of the next generation of the older Australian population will be different to that of the previous generation. The distribution of Australians aged 65+ and 80+ in 2021 and 2031 will be quite different to that of 2001 and 2013. Yet much of the aged care infrastructure, especially residential care are ‘location specific capital’ (De Vanzo, 1981). They have a fixed location which will be increasingly mismatched with the location of older Australians. The Growth of Australia’s Older Population Australia’s population is currently growing at 1.8 percent per annum (ABS, 2014), one of the fastest population growth rates in the world and certainly the fastest among OECD countries. Table 1 shows that over the most recent intercensal period the 65+ population grew significantly faster than the total population and working age populations. The most rapid growth was in the ‘young aged’ 65-74 ages as they begin to be entered by baby boomers. Table 1: Source: Australia: Population Change by Age, 2006-11 ABS 2011 Census 2006 2011 % Change Total 19,855,291 21,507,716 8.3 65-74 1,373,435 1,627,407 18.5 75+ 1,270,935 1,384,880 9.0 65+ 2,644,370 3,012,287 13.9 13,273,710 14,351,405 8.1 15-64 Population projections over the next two decades, however, show that the growth of those aged 65+ will be more than twice as fast as the total population (Table 2). Moreover -4- the fastest growth will be in the ‘old old’ 75+ age groups. These are the age groups which have the highest level of demand for aged care and other services, especially health. Table 2: Source: Australia: Population Change by Age, 2011 and Projected 2031 ABS Estimated Resident Population and 2031 Projections Series B 2011 2031 % Change Total 22,340,024 30,501,192 36.5 65-74 1,681,931 2,878,511 71.1 75+ 1,405,980 2,826,768 101.1 65+ 3,087,911 5,705,279 84.8 15,018,500 19,255,273 28.2 15-64 To underline the high degree of confidence we can place in these numbers, Table 3 provides the projections for the three main scenarios of future population change which the ABS has provided – Series A, B and C – respectively high, medium and low population growth scenarios. It will be noted that there is little variation in the numbers of 65+ anticipated by all three scenarios (2.5 percent). This is because the aged population of the next three decades will not be influenced by fertility and little affected by migration. It will, however, be noted in Table 3 that there are more significant differences in the percentage that the aged will represent in the total population under the different scenarios (8.8 percent). Table 3: Source: Australia: Comparison of Projected Growth of Population, 2031 ABS 2013 Projections 2011 (m) Total Population Difference Series A Series B Series C 2031 (m) 2031 (m) 2031 (m) in 2031 (m Series A and C) 22.34 31.87 30.5 29.3 2.57 65+ 3.09 5.83 5.71 5.69 0.14 Percent 65+ 13.8 18.3 18.7 19.4 1.1 -5- This is because the higher growth projections assume higher levels of migration and fertility which lead to greater increases of the young population and reduce the proportion that the aged comprise of the total population. The crucial point, however, is that there is really only one realistic scenario with respect to the future numerical growth of Australia’s older population. There are only different scenarios with respect to the proportion they make up of the total population. Why is Australia’s Population Ageing? Trends in the numbers of older people (say those aged 65 years and over) in any area are a function of the following demographic processes. Fertility – the rate at which women in that area were having children 65-90 years ago. Mortality – the rate at which older people are lost to death. Migration – the extent to which older people move into or out of the area. The ‘ageing in place’ of residents in the area into the 65+ age groups. In Australia all of these processes are contributing to the unprecedented increase in its older population and will continue to do so over the next two decades. Fertility The most salient demographic element in the ageing of the Australian populations over the next three decades is the Baby Boom generation moving into the retirement ages. Figure 1 shows the Australian Total Fertility Rate2 over the last century and it can be seen that the period following World War II saw an upswing in the number of babies women were having on average. While most countries experience an upswing in fertility after a war, the 2 The TFR can be defined as: the average number of children that would be born alive to a woman during her lifetime if she were to pass through all her child-bearing years conforming to the age-specific fertility rates of a given year. -6- Australian post-World War II boom was greater and longer lasting than most. Indeed it was sustained for two decades. This created a ‘bulge’ in the Australian age pyramid which, as -7- Figure 2 shows, has subsequently moved upwards and is now entering the 65+ age group. Because fertility has subsequently almost halved, the baby boom has created a ‘shock wave’ of rapidly increasing numbers in particular ages as the cohort has passed through different life cycle stages.3 Figure 1: Source: 3 Australia: Total Fertility Rate, 1901-2012 CBCS, Demography and ABS, Births Australia, various issues The first baby boomers turned 65 in 2011 and will begin passing 70 in 2016 and 85 in 2031. -8- Figure 2: Source: Australia: Age Structure 1961 to 2011 Showing Baby Boomer Cohort ABS Censuses 1961 85+ 80-84 Females Males 75-79 70-74 65-69 60-64 55-59 50-54 Age 45-49 40-44 35-39 30-34 25-29 20-24 15-19 10-14 5-9 0-4 800 600 400 200 0 200 400 600 800 Number (000s) 1986 85+ 80-84 Females Males 75-79 70-74 65-69 60-64 55-59 50-54 Age 45-49 40-44 35-39 30-34 25-29 20-24 15-19 10-14 5-9 0-4 800 600 400 200 0 200 400 600 800 Number (000s) 2011 85+ 80-84 Females Males 75-79 70-74 65-69 60-64 55-59 50-54 Age 45-49 40-44 35-39 30-34 25-29 20-24 15-19 10-14 5-9 0-4 800 600 400 200 0 Number (000s) 200 400 600 800 -9- Figure 3: Source: Australia: Expectation of Life at Birth, 1870-2011 Hugo 1986 and ABS Deaths Australia, various issues Mortality and Life Expectancy Another factor contributing to ageing of the Australian population, as Figure 3 shows, is the steep increase in life expectancy among Australians over the last century. In the period since World War II we have added 12.6 years of life to Australian males and 12.9 years to females. Hence more Australians are surviving their younger years than ever before. However, perhaps the biggest change in life expectancy has come in the older ages. Prior to 1970 we had added very few years of extra life to Australians aged 50 years or more, although major improvements were recorded in their chances of making it to age 50. Table 4 shows that between 1901 and 1970 only 1.8 extra years of life were added to Australian - 10 - males aged 50. The increase was greater for women (4.6 years) because of the reduction in pregnancy/child birth related deaths. However the table shows that there has since been a dramatic change with 8.8 years being added to the life expectancy of Australian men aged 50 between 1970 and 2011 and 7.3 years for women of that age. This massive change was not anticipated by commentators at the time (National Population Inquiry, 1975, 1978). It was Table 4: Source: Australia: Expectation of Life at Age 50, 1901-1910, 1970-72, 1981 and 2011 ABS Year Males Females 1901-1910 21.2 23.7 1970-1972 23.2 28.3 1981 25.2 30.8 2011 32.0 35.6 achieved on the one hand through medical breakthroughs such as better diagnosis of heart conditions, bypass operations and the development of Intensive Care Units. On the other hand, major improvements in lifestyle through better diet, reduced smoking and safer cars have also had an impact. As a result, not only are more Australians surviving to reach retirement age but more are having an extended period of retirement. This is contributing significantly to the growth of our older population. On average, Australian males reaching 65 in 2012 could expect to live to age 84 and women 87. Longevity, Health and Disability Increased longevity of Australians is, of course, a good news story although its implications for income support, superannuation, the age of retirement etc. are currently being worked through. From the perspective of demand for aged care it is not only the extra - 11 - years of life which is of significance but it is the number of extra years which are years lived with disability. A Global Burden of Disease (2012) study for the 1990-2010 period found that in high income countries the gain in years of extra life lived as a result of decreases in mortality has been largely offset by years of life lived with disability. Public perceptions are that baby boomers are healthier than previous generations but is this the case? There are a number of factors which would lead us to conclude that they are likely to be healthier: Baby boomers are in many ways a privileged generation being the first generation to grow up in an era of increasing affluence and prosperity. They have unprecedentedly high levels of education compared with earlier generations. They were the first generation to grow up in an era of expanding job and educational opportunities. They were the first generation to grow up having access to immunisation and antibiotics. They have substantially lower levels of smoking than previous generations. On the other hand there are some arguments for suggesting they could have a higher level of disability than previous generations: Firstly, the very medical breakthroughs which have ‘rescued’ baby boomers from dying of a heart attack or stroke like the previous generation may in fact leave them with a chronic illness or disability. Secondly, baby boomers, more than previous generations, have adopted increasingly sedentary life styles and have a higher incidence of obesity than any previous generation. - 12 - Whether or not Australia fits the High Income Country Model established by the Global Burden of Disease (2012) study is of particular significance to anticipating future need for aged care. If the Australian situation were to conform to that pattern the changes in mortality would have delivered a ‘double whammy’ to the future demand for health and aged care. There will be many more older people than we previously anticipated. On average they will have higher levels of chronic illness and disability. However, the data presently available do not allow us to give a definite answer. Perhaps a detailed analysis of the most recent ABS Health Survey, which for the first time collected clinical data and did not rely totally on self-rated health, will clarify the issue. Table 5 presents results of ABS sample surveys of self-completed health for ages 45 and over between 1981 and 2012 and some complex patterns are in evidence. Table 5: Source: Proportion of the Population with Disabilities, 1981-2012 ABS, 1999 and 2013b Age Group 1981 1988 1993 1998 2003 2009 2012 45-54 16.7 17.4 18.4 20.9 21.6 18.0 18.1 55-64 27.1 30.5 30.9 33.4 33.8 31.8 29.4 65-74 34.6 44.0 45.3 44.8 44.4 43.6 42.0 75+ 53.1 63.4 64.0 67.5 68.0 65.2 67.6 All People 13.2 15.5 16.6 18.8 20.0 18.5 18.5 There is an overall increase in the proportion of the population reporting a disability up to 2003 and thereafter a small decline. For the 75+, 45-54 and 55-64 population there was also an increase up to 2003 and thereafter a small decline. For the 65-74 group the proportion with a disability peaked in 1993 and has declined since then. - 13 - The self-report data hence do show a pattern of a small decrease in the incidence of disability in older ages but this should be treated with caution. A recent study by the Australian Institute of Health and Welfare (2014, 3) has examined the change in life expectancy in Australia between 1998 and 2012 and the results are summarised in Table 6. They show that virtually all of the increase in life expectancy between 1998 and 2012 (4 years for males and 2.8 years for females) were disability free years. This result would indicate that in Australia, at least in recent years, the increase in longevity has not increased the number of years that Australians on average will spend with a disability. However, these data remain based on self-reported health and such data is not only questionable but also is subject to systematic change over time. It is only through the use of clinical data, as was collected in the most recent ABS Health Survey, that more definitive statements can be made. Table 6: Source: Australia: Disaggregation of Life Expectancy Into ‘Disability Free’ and ‘With Disability’ Years, 1998 and 2012 (Years) AIHW, 2014, 3 Male Female 1998 2012 1998 2012 Life Expectancy at Birth 75.9 79.9 81.5 84.3 Disability Free Expectancy 58.0 62.4 62.1 64.5 With Disability Expectancy 17.9 17.5 19.4 19.8 One of the most important determinants of future need for aged care relates to the incidence of dementia. The Global Burden of Disease (2012, 2218) study of years living with disability found that there was a largely unrecognised burden of mental illness in both developed and underdeveloped nations. In the Australian context Access Economics (2011, - 14 - 9) projected the numbers with dementia to more than double from 266,574 in 2011 to 553,285 in 2030 and by 2050 would number 942,624. This would suggest that the numbers of Australians living with dementia would increase significantly faster than the total population over this period. With an increasing proportion of residential care residents suffering dementia such projections would appear to have very significant implications for future demand for both residential and home care packages. However, the uncertainty around these projections was recently drawn attention to by Sachdev (2014) who draws upon European evidence to suggest that projected levels of prevalence of dementia were not being reached. It is apparent that action on preventative health, especially improving diet and exercise and reducing obesity could lower the risk of dementia for future generations. Accordingly, while there is a high degree of certainty about the numbers of older Australians, there will be over the next quarter century a great deal of uncertainty about the proportion of them who will be needing care, both residential and home. There is a pressing need to develop a number of specific scenarios with respect to future prevalence of disability and dementia in order to develop more nuanced and informed projections of future need for aged care. This is fundamental to maintaining and enhancing the effective, efficient and equitable provision of aged care support services in Australia. International Migration It is sometimes suggested that a ‘solution’ to Australia’s ageing population is to be found in international migration. International migration is highly selective of the young adult population and hence migration can have a ‘younging’ effect. However, immigrants themselves age so that their overall impact on age structure is limited (Young, 1988). Indeed the massive immigration of young adults in the early postwar decades is now contributing significantly to the growth of Australia’s older population as these immigrants ‘age in place’. - 15 - In fact, Australia’s overseas-born population is older than the Australia-born with 19.0 percent aged 65 in 2011 compared with 11.9 percent. Australian postwar immigration has had a profound impact on the contemporary older population. With half its population being either overseas-born or Australia-born with an overseas-born parent, Australia is more influenced by migration than any other OECD country. Moreover - 16 - Figure 4 shows that the intake has gone from being overwhelmingly mono-culturally Anglo Celtic to one of the most ethnically diverse global inflows. Due to the - 17 - Figure 4: Australia: Settler Arrivals by Region of Last Residence, 1947-1996, and Permanent Additions by Region of Birth, 1997-2013 DIBP data Source: 300000 250000 Number 200000 150000 100000 50000 2012-13 2009–10 2006–07 2003–04 2000–01 1997–98 1994-95 1991-92 1988-89 1985-86 1982-83 1979-80 1976-77 1973-74 1970-71 1967-68 1964-65 1961-62 1958-59 1955-56 1952-53 1949-50 *1945-47 0 Year UK and Ireland Other Europe Africa Americas NZ and Pacific Middle East Asia *July 1945 to June 1947 Note: Middle East includes North Africa from 1996-97. young age of migrants at the time of the move, the impact in diversifying Australia’s aged population has been delayed. However, Table 7 shows that the overseas-born population aged 65+ has almost doubled since 1991 while the Australia-born grew by around a third. In 2011, 36 percent of Australians aged 65+ were overseas-born and 22 percent were from Culturally and Linguistically Diverse (CALD) backgrounds. -2- Table 7: Source: Australia: Population Aged 65+ by Birthplace, 1971-2011 ABS 1971-2001 Censuses Australia-Born Year No. 1971 1976 1981 1986 1991 1996 2001 2006 2011 816,396 913,075 1,053,565 1,188,679 1,323,473 1,418,879 1,485,462 1,560,584 1,787,009 % 8.0 8.4 9.2 9.8 10.4 10.7 10.9 11.1 11.9 Non-English Speaking Origin-Born Overseas-Born % Growth pa 2.3 2.9 2.4 2.2 1.4 0.9 1.0 2.7 No. 248,599 295,911 350,839 458,041 528,335 620,898 726,558 840,503 1,004,641 % Growth pa % 9.6 10.9 11.7 14.1 14.1 15.9 17.7 19.0 19.0 3.5 3.5 5.5 2.9 3.3 3.9 3.0 3.6 * % growth 1971-81 No. 75,433 na 135,678 222,972 271,054 352,958 433,617 509,860 608,449 % 5.6 9 13.3 12.4 14.9 17.3 18.6 18.0 % Growth pa +6.0* 10.4 4 5.4 4.2 3.3 3.6 Mainly English Speaking Origin-Born % No. % Growth pa 173,166 14.1 na 215,161 14.4 +2.2* 235,069 15 1.8 257,281 16.4 1.8 267,940 17.3 0.8 292,941 18.3 1.8 330,543 19.7 2.4 396,192 20.8 3.7 -3- How do Baby Boomers Differ from the Previous Generation Entering Old Age? The passage of baby boomers into older ages thus represents a massive quantitative change with a doubling of the numbers aged 65+ in the next quarter century and an even greater growth of those aged 75+. However, it is more than a quantitative change. Baby boomers differ significantly economically, socially and culturally and in their attitudes, resources and expectations from the previous generation born in the 1910s, 20s and 30s. This will profoundly influence the way they tackle and experience the post-retirement years. They will not behave the same and service providers catering to this age group must recognise that it will not simply be a situation of ‘more of the same’. What are some of the major ways in which baby boomers are different? While there is considerable diversity in each generation, baby boomers are more segmented than the previous generation. While ‘mass market’ options were possible for many of the previous generation, baby boomers have created more differentiated markets for all the goods and services they have demanded and needed as they reach each stage of the life cycle. It will thus be a highly segmented market, not only for aged housing and aged care but for all the goods and services older people use. This will mean that policies, programs and approaches which have been successful among the current generation of 65+ people will not necessarily work for baby boomers. In order to demonstrate this we have compared the characteristics of the current older generation at the time they entered the older ages in the 1980s with the current characteristics of baby boomers who are just reaching this stage of the life cycle.4 4 This analysis was undertaken by Dr. Jennifer Buckley of the Australian Population and Migration Research Centre. -4- Table 8 compares some key demographic, economic and social characteristics of the two groups with the following being particularly important: The baby boomers are the first generation of Australians to experience high rates of divorce and separation so that a third are entering their older years without a spouse compared with less than a fifth among the previous generation. The proportion of baby boomer women who had never had children was significantly higher (14 compared with nine percent). The proportion living alone is twice as high. One of the largest differences relates to education with 43 percent of boomers who had completed secondary school compared with only six percent of the previous generation. Moreover, while almost a fifth of baby boomers had a Bachelor or higher degree qualification, only three percent of the older generation did. -5- Table 8: Source: Australia: Baby Boomers and Pre-war Generation As They Enter Old Age, Social Indicators ABS National Health Surveys 1989-90 and 2008-09; ABS Census 1981 and 2006 Baby Boomers Pre-war Generation (1946-65) (1927-36) % % Entering later life without a spouse 34 19 Childless 14 9 Living alone 11 6 Completed secondary school 43 6 Bachelor degree or higher 19 3 66 80 Owner/purchaser 80.7 84.1 Rental 19.3 15.9 No Private Health Cover 37 42 Overseas-Born 31 21 NES Overseas-Born 20 12 Social Indicators Social Supports Education Religion Identify as Christian Housing A higher proportion of the previous generation identified themselves as a Christian. While both had high rates of home ownership, the percentage renting among baby boomers is higher (19.3 compared with 15.9 percent). Two thirds of baby boomers have private health cover compared with 58 percent of the older generation. Baby boomers are more ethnically diverse with 31 percent overseas-born (compared with 21 percent) with a fifth being born in a CALD country (compared with 12 percent). -6- This small slice of the wide difference between the generations is indicative of how there are significant differences in attitudes, perceptions, characteristics, resources and experience which will mean their behaviour, expectations and demand for services will also differ. They certainly need to be considered when considering the future aged care needs of this group. For example: The extent to which baby boomers will be able to call upon a partner or a child to assist in their day to day care will be considerably less than the previous generation of older Australians. Yet policy is to increase the proportion of care being delivered at home rather than in a residential care context. The proportion of baby boomers owning their home outright will be less than is currently the case. Yet home ownership is one of the three pillars of the Australian aged care system. Increasing cultural diversity presents many challenges in aged care provision because until relatively recently the population aged 85+ was overwhelmingly Anglo Celtic in origin. One of the most important dimensions of difference between generations relates to health. Much of the public and policy discourse on the ageing of baby boomers has focused on the pressure that this will place on Australia’s health system. Indeed, they will lead to nearly a doubling of the population aged 65 years and over in the next quarter century. Unfortunately most of the data we have available on health, however, is self-reported and, as was explained earlier, needs to be interpreted carefully. Figure 5 shows that there is a pattern of demand for health services increasing significantly in the older years in Australia. However, as was indicated earlier, the implications for the health system are more severe than is suggested by the sheer increased -7- numbers of older people. Although there are problems Figure 5: Source: Australia: Persons 15 Years and Over, Visited a GP 12 or More Times in the Previous 12 Months ABS, 2012 with the data when we make the direct comparison across generations, the evidence is that they have a higher rate of illness and morbidity than the previous generation. Most tellingly, Table 9 shows that baby boomers are eight times more likely than the older generation to have three or more health problems. This perhaps reflects the ‘rescued from death’ factor discussed in an earlier section, although comparability of the data over time can be questioned. Nevertheless, the data in Table 9 indicate the nature and scale of the health challenge which the baby boomers pose. The incidence of obesity and overweight is two and a half times that of the previous generation. The close links between obesity and poor health makes it imperative that our efforts to reduce obesity in the Australian population include a -8- strong focus on baby boomers. Partly associated with obesity patterns, the incidence of diabetes is three times higher and asthma twice as great. It is interesting that the only risk factor for which baby boomers are better off is smoking with 18 percent of boomers currently smoking compared with a quarter of the older generation. Table 9: Source: Health Status at Mid-life: Baby Boomers Compared with Pre-war Generation ABS; National Health Surveys, 1989-90, 2007-08 Baby Boomers Pre-war Generation at Mid-life at Mid-life % % Obesity 26 12 Diabetes 9 3 Asthma 10 5 Hearing loss 17 8 Arthritis 33 26 Migraine 6 4 Back problems 9 6 Multiple conditions (≥3) 4 0.5 High cholesterol 14 8 Alcohol risk 15 11 Currently smoking 18 24 Emphysema/bronchitis 3 5 No private health cover 37 42 Health Indicators Differences Within the Baby Boomer Generation In the last section we have demonstrated that baby boomers as a group are clearly different to the previous generation entering the older years. However, it is very important to realise that there is considerable variation within the baby boomer generation. It is important to recognise that in fact it is a more diverse generation than the one which preceded it. Nevertheless there are pervasive stereotypes such as the baby boomers being a ‘cashed up’ -9- generation. Figure 6, indeed, shows that baby boomers in the 55-74 age group had the highest wealth levels of all generations. Moreover they have the fastest growing wealth levels with the situation being quite static below age 45. However, it would be wrong to characterise all baby boomers as being wealthy. There is in fact a significant number of baby boomers who are highly vulnerable to experiencing significant problems once they enter the older age groups. We will demonstrate this using data from the South Australian Monitoring and Surveillance System (SAMSS). Figure 6: Source: Australia: Average Household Net Worth by Age of the Household Reference Person, 1994-2012 ABS, 2002, 2007 and 2013c - 10 - One important measure of differentiation relates to housing. It is often assumed that ownership of the family home provides the basis for the wellbeing of the older population. Yet as was indicated earlier, a smaller proportion of baby boomers than the previous generation are entering the older ages owning their own home than previous generations. Table 10 presents data from the Australian 2011 population census and shows that the proportions renting increase substantially with each successive generation. Moreover the proportion who had a mortgage increases even more suggesting that the numbers of baby boomers who will still have a mortgage debt when they leave the workforce will be much greater than was the case for the previous generation. Table 10: Source: Australia: Tenure by Age, 2011 ABS 2011 Census Tenure 45-54 55-64 65-74 75+ Percent Owned outright 27.5 51.3 72.1 76.2 Owned with a mortgage 49.4 30.9 12.2 6.6 0.2 0.1 0.1 0.1 21.5 16.2 13.4 12.6 Being occupied rent-free 0.8 0.8 0.8 1.0 Being occupied under a life tenure scheme 0.1 0.2 0.8 2.5 Other tenure type 0.4 0.4 0.5 1.1 100.0 100.0 100.0 100.0 2976481 2532605 1644047 1391101 Being purchased under a rent/buy scheme Rented Total N The baby boomers who are renting represent a group who have high levels of vulnerability to experiencing difficulty in old age when their income reduces due to leaving the workforce. This is evident in data collected in a survey of the South Australian population. In putting together data from the SAMSS for the 2007-13 period there were 13,425 baby boomers, of whom 1,229 (9.1 percent) were renting. Comparisons of those renters with other baby boomers (owners and purchasers) showed there were some very - 11 - striking differences. Table 11 shows that renters were significantly more likely to not be in the workforce, not have tertiary education, be currently married and be in the lowest income quintiles. This disadvantage is carried through to health and Table 12 shows that they are at much higher risk of having a chronic disease or disability. Most tellingly, they are twice as likely to have a mental health problem. Table 11: Source: Table 12: Source: Comparison of Owners and Renters: Demography SAMSS, 2007-13 Owners (%) Renters (%) Percent Employed 75.7 56.9 Percent with Degree 24.1 15.0 Currently Married 83.9 46.1 Percent in 2 Lowest SEIFA Quintiles 34.4 49.4 Comparison of Owners and Renters: Chronic Conditions SAMSS, 2007-13 Owners (%) Renters (%) Diabetes 7.8 13.0 Asthma 10 16.8 COPD 4.4 8.4 Arthritis 25.9 31.6 Osteoporosis 3.8 5.6 Mental Health 15.4 29.6 At Least One Chronic Condition 47.4 61.1 Clearly there is a significant group among baby boomers who are very vulnerable to disadvantage. Those who are currently renting are especially important in that respect. These are factors which must be taken into account in developing a range of future scenarios with respect to need for aged care. - 12 - A Different Spatial Distribution Where older people live is important for a number of reasons: Older people have lower levels of personal mobility which means they are restricted in their ability to travel long distances to obtain services and interact. Housing is often the major element in older people’s assets. Their local area is often where their main social contacts are located. Their home can hold many important memories crucial to their wellbeing. There is a literature which shows a high level attachment to home place among older Australians (Pinnegar et al., 2012, 12). However, there is some discussion as to the extent to which it is attachment to the actual dwelling they occupy and the extent to which it is to the locality in which they live. This is a crucial distinction from the perspectives of both policy and the wellbeing of older Australians. The distribution of the older population is also important because the elderly are historically among Australia’s least residentially mobile groups. Figure 7 shows the proportion of each age group moving in the five years previous to the 2011 and 1991 censuses and it will be noticed that there has been little change in the extent to which older Australians have changed their place of residence over the last two decades. Traditionally, mobility tends to be greatest upon retirement when, as Table 13 shows, most moves are voluntary and involve moving to more environmentally amenable locations or trading down to age-appropriate housing. However, in the oldest years movement is generally forced on people due to the onset of disability or the loss of a spouse. Table 14 presents results of five intercensal periods in Australia since 1976 which suggest that the overall level of residential mobility among older Australians over the last 35 years has reduced. Several things are operating here such as the increased independence of older people which has allowed them to remain in their home longer as well as government policy encouraging people to ‘remain at - 13 - home rather than in a home’. Nevertheless, there is no evidence of an upswing in ‘young aged’ migration. Figure 7: Australia: Persons Who Moved in the Last Five Years by Age, 2001-06 and 2006-11 ABS 2006 and 2011 Censuses Source: 180000 160000 Moved 2006-2011 Moved 2001-06 140000 120000 100000 Number Moved 80000 60000 40000 0 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99 20000 Age in years Table 13: Source: A Typology of Migration of Older Australians Hugo, 1988, 17 Age Type ‘Young Old’ M ainly Voluntary Selectivity Reason for M oving Higher Income 60s and early 70s ‘Old Old’ 70s and over Showing Element of Compulsion - recreational, retirement to resort locations – environmental factor - trade down to age-appropriate housing Lower Income - closer to children Little Selectivity - forced housing adjustment – renters and mortgage holders - onset of widowhood or disability forces move to be closer to children - inability to live independently forces need to live with children or residential care - 14 - Table 14: Source: Australia: Percent Who Moved in the Last 5 years, 1976-81 to 2006-11 ABS Censuses; 1981-2001 ABS, One Percent Sample Year 60-64 65-69 70-74 75-79 80+ 1976-81 26.9 26.8 24.7 24.4 32.9 1986-91 30.7 28.1 27.2 26.2 32.5 1996-2001 26.0 24.6 19.7 21.0 25.7 2001-06 24.7 22.2 19.7 18.7 23.6 2006-11 21.9 19.8 17.1 15.9 20.7 However, the important question relates to the extent to which baby boomers will move to a greater (or lesser) extent than previous generations of older Australians. The whole thrust of current government policy is to reduce, or at least delay, ‘forced’ moves from independent living to residential care. The changing of the mix of independent and residential care in the housing of older Australians is one of the key targets of aged policy that needs to be monitored closely. An important immediate question, however, is the extent to which baby boomers will make residential adjustments as they enter or approach retirement. It must be said that the jury is still out on this question. Certainly the substantial increase in the age at which people are leaving the Australian workforce (Table 15) means that baby boomers will have delayed the decision of whether or not to move upon retirement compared with their counterparts of the 1990s and early 2000s. The evidence about baby boomer residential mobility is limited and mixed. Beer and Faulkner (2009, 133) found that 41.5 percent of respondents aged 55-64 in 2006 had moved to their current home in the last 10 years – a higher level of mobility than is reflected in census data. Olsberg and Winters (2005) found that two thirds of their respondents wanted to say in their own homes. There is then a need to more fully investigate the housing intentions of baby boomers but also to carefully monitor three key types of retirement related migration over the next decade: - 15 - Table 15: Source: Australia: Changes in Participation Rates of the Older Population in the Workforce, 1970-2014 ABS Labour Force Surveys Age Group Percent Participation M ay 1970 M ales June 1999 Females M ales Feb 2010 Females M ales Jan 2014 Females M ales Females 55-59 91.5 28.7 72.9 44.1 79.4 64.4 79.0 63.5 60-64 79.2 14.9 46.9 17.6 61.7 41.8 61.8 42.5 65+ 23.2 3.6 9.7 3.2 14.8 6.4 16.0 7.5 1. Migration to environmentally amenable resort communities in coastal, riverine and other non-metropolitan areas. 2. Voluntary trading down to more age-appropriate housing within metropolitan areas. 3. Involuntary trading down among renters and mortgage holders who are unable to keep up payments when they cease full-time work. While recognising that any significant shift in residential mobility levels and patterns may produce changes, we will now turn to examine the current spatial distribution of older Australians. Ageing in place has been, and will continue to be, the major process whereby the older population of any area will increase or decrease and this has advantages in facilitating projection of future changes in the aged population of individual areas. Table 16 shows that the majority (65.4 percent) of Australia’s older population live in major cities (those with more than 100,000 residents). However, they are less concentrated in these cities than is the case for the total population (69.5 percent). Until 1996 the proportion of major city populations aged 65+ was above the total population average but the increasing movement of older people to coastal areas and regional cities has changed the metropolitan/non-metropolitan balance. Moreover the extent to which this has occurred is masked to some extent in Table 16 because over the 1981-2011 period a number of regional centres increased in population and moved from being ‘other urban’ to ‘major urban’. - 16 - Moreover there was a considerable extension of the urban boundaries of Australian capital cities. Hence, the redistribution from larger cities to smaller cities and urban places is greater than is indicated in Table 16. The proportion of the elderly living in rural areas has increased slightly between 1981 and 2011 but 11.1 percent of the nation’s 65+ population live in such areas compared with 10.9 percent of the total population. The rural elderly grew significantly faster (2.65 percent per annum) than the total population in rural areas (0.38 percent) between 1981 and 2011. Table 16: Source: Australia: Growth of Population, 1981-2011 ABS Censuses 1981 and 2011 65+ Population Section of State 1981 No. 2011 Total Annual Rate of Growth Population 1981-2011 % No. % 2011 (%) Population Total Major Urban 919,096 64.3 1,965,505 65.4 69.5 2.57 1.61 Other Urban 358,562 25.1 708,788 23.6 19.6 2.30 0.81 Rural 151,743 10.6 332,460 11.1 10.9 2.65 0.38 Total 1,429,401 100.0 3,006,733 100.0 100.0 2.51 1.29 There is a problem in interpreting the data in Table 16 due to the movement of places between categories over an intercensal period. In order to overcome this we have held the capital city division boundaries constant between 2006 and 2011 to compare the changes in the total and 65+ population. This analysis indicates that for the total population the average annual growth rates between 2006 and 2011 are 1.8 percent compared with 1.26 percent for non-metropolitan areas outside of the capital cities. However, for the 65+ population, the situation is reversed. In the capitals the 65+ population grew by 2.45 percent per annum – a very fast growth rate – 36 percent higher than that for the total population. However, for non-metropolitan areas the 65+ population grew even faster at 2.9 percent per annum – 130 percent higher than for the total population. This is clear evidence that the older - 17 - population is growing faster outside of the capitals than within them. Moreover it is also evident that retirement migration from capitals to non-metropolitan, especially coastal, areas is playing a role in this. While it is important to bear in mind that over a third of older Australians live in places of less than 100,000 inhabitants, the majority live in large cities, especially the metropolitan capital cities. It is important, therefore, to examine the changing distribution of older populations in those cities. To illustrate some of the key patterns we will use Metropolitan Adelaide. Figure 8 presents data on the changing distribution of older people within Adelaide between 1971 and 2011 and divides the metropolitan area up into inner, Figure 8: Adelaide Statistical Division: Distribution of Population Aged 65 Years and Over Between Metropolitan Sectors, 1971-2011 ABS 1971 to 2011 Source: 80,000 70,000 Persons 60,000 50,000 Inner 40,000 Coastal Middle 30,000 Outer 20,000 10,000 0 1971 1981 1991 1996 Year 2001 2006 2011 coastal, middle and outer sectors, the boundaries of which have been presented elsewhere (Hugo, Rudd and Downie, 1984). Some quite spectacular changes are in evidence over the last 40 years in which the aged population of Adelaide more than doubled. In 1971 almost a - 18 - third of Adelaide’s elderly lived in the inner suburbs where 15.4 percent of the population were aged 65 or over and a similar situation applied in the coastal SLAs. Together these older areas had 44.5 percent of the elderly. However, by 1991 the elderly population of the inner suburbs had begun to decline so that their share of the 65+ proportion fell from 30 to 13.4 percent. Similarly with the coastal suburbs where, although there was growth in numbers, their share of the total Adelaide aged population fell. Together they accounted for 28.1 percent of the city’s elderly. By 2011 these patterns had continued so that only 24.4 percent of the 65+ population lived in these two areas although coastal areas maintained their share. Clearly urban renewal, urban consolidation and gentrification have had significant impacts in these areas and much of the recent population growth in these areas has been of younger people. The middle suburbs show an interesting pattern with the numbers aged 65+ doubling between 1971 and 1991 and their share of the metropolitan aged population increasing to 45.6 percent. However since then the numbers have begun to decline with the death and outmigration of older people who had settled these suburbs as young families in the late 1940s, 1950s and 1960s. Accordingly their share of the metropolitan aged population has fallen to 33.3 percent in 2011. Nevertheless the number of older people in the middle suburbs is still substantial. The real growth of older populations however is in the outer suburbs. The number of people aged 65+ in this area quadrupled between 1971 and 1991 and more than doubled again by 2011. The proportion of the Adelaide population aged 65+ in this zone has increased from 12.4 percent in 1971 to 42.3 percent in 2011. The older population in this area increased about 8 times over the last three decades to number 77,350. Hence a much greater proportion of our older population are living in low density suburbs with nucleated shopping centres, low density network of public transport and low density of services for the elderly. The crucial point is that the centre of gravity in the spatial - 19 - distribution of older persons has shifted from the inner to the middle suburbs and the most rapid rate of growth of the aged population is even further out in the outer suburbs. There is an important deconcentration of the older population in Adelaide occurring as is evident in Figure 9 which depicts the growth rate of the 65+ population by SLA over the 2006-11 intercensal period. A striking pattern is in evidence with all growth above 5 percent per annum being in the outer suburbs while inner and inner-middle suburbs experienced slow growth or even declines in the number of older people5. The only other growth area is in the Figure 9: Source: 5 Adelaide Statistical Division: Growth of the Population Aged 65+ by SLA, 2006-11 ABS 2006 and 2011 Census The Elizabeth area is also experiencing a decline of its older population reflecting the fact that it was developed as a satellite city in the 1950s. - 20 - long established seaside area of Holdfast Bay which is favoured both for retirement migration and has a number of aged care residential facilities. The patterns and dynamics described here for Adelaide are duplicated in other capital cities and can be summarised as follows: The highest concentrations in terms of the percentage of the total population aged 65+ and 75+ are highest in inner and middle suburbs due largely to institutions being located in these areas. The largest numbers of older people is now in the middle suburbs but the fastest growing numbers are in the outer suburbs. In the past most people in the pre-retirement ages or retirement ages have ‘aged in place’ in the same house in which they bought up their children. There are some interesting signs that the baby boomer generation may be showing a greater tendency to sell the family home when they have become ‘empty nesters’. This however is yet to be fully established since baby boomers are delaying retirement. There are some patterns where baby boomers are selling their houses in the outer suburbs and downsizing to inner suburban areas and coastal suburbs within the metropolitan area. The changing distribution of older people within Australian metropolitan areas raises important issues about providing services to them. Where the services are mobile and homebased, shifts in the population distribution can readily be accommodated. However, where they involve fixed capital investment, as is the case with residential care establishments, there are the dangers of an increasing mismatch between the location of the supply (residential care) and of demand (older people). Figure 10 depicts the distribution of aged care beds in Metropolitan Adelaide in 2000 and 2013. This shows that there has been a significant change - 21 - Figure 10: Metropolitan Adelaide Sectors and Aged Care Beds, 2000 and 2013 - 22 - in the distribution over this period in response to the changing distribution of the aged population discussed here. Table 17 shows how there has been a significant change in the distribution of aged care beds in Adelaide over the 2000-13 period with an 18.6 percent decline in the inner suburbs and a doubling in the outer suburbs. Clearly there has been a significant response to the changing distribution of the older population in Adelaide. Table 17: Source: Adelaide Statistical Division: Number of Aged Care Beds in Suburban Sectors, 2000 and 2013 Aylward, Hugo and Harris 2000; Department of Social Services, unpublished data Low Care Beds High Care Beds Total Beds % Change Suburban Sector 2000 2013 2000 2013 2000 2013 537 696 780 651 1317 1347 2.3 Inner 1290 889 1618 1479 2908 2368 -18.6 Middle 1836 1970 2311 2161 4147 4131 -0.4 Outer 1299 2244 1269 2932 2568 5176 101.6 Total 4962 5799 5978 7223 10940 13022 19.0 Coastal 2000-2013 However, the growth of the aged population over the next three decades will be unprecedentedly high and the dangers of a mismatch between the location of aged care residential facilities and of the older people needing them increasing. Table 18 shows the projected increase in Adelaide’s older population over the period 2011-26. Some 54.3 percent of the growth of the 70+ population will be in the outer suburbs and another 26.5 percent in the middle suburbs. Hence there will be an increasing mismatch between the distribution of beds and the distribution of older people unless the decentralisation of beds, which has been recorded over 2000-2013 is continued (Table 19). In considering the changing distribution of the older population it is important to bear in mind that more than a third of aged Australians live outside the capital cities. There are particular concentrations in the following ‘types’ of non-metropolitan areas. - 23 - Table 18: Metropolitan Adelaide: Total Population and Aged 70+, 2011 and Projected 2021 and 2026 ABS 2011 Census and ABS for the purpose of the Commonwealth, through the Dept. of Health and Ageing, and other governments, 2007 Source: 2011 2021 2026 Suburban Sector Total 70+ Total 70+ Total 70+ Coastal 104562 14626 111308 18630 113273 21098 Inner 144029 16865 170895 21676 180249 25035 Middle 365171 47449 408564 60141 425330 67747 Outer 554644 53035 635464 80827 665689 94587 Total 1168406 131975 1326231 181274 1384541 208467 Table 19: Source: Metropolitan Adelaide: Number Beds/1000 persons Aged 70+, 2011 and Projected 2021 and 2026 ABS 2011 Census and ABS for the purpose of the Commonwealth, through the Dept. of Health and Ageing, and other governments, 2007 Suburban Sector 2011 2021 2026 Coastal 92.1 72.3 63.8 Inner 140.4 109.2 94.6 Middle 87.1 68.7 61.0 Outer 97.6 64.0 54.7 Total 98.7 71.8 62.5 Firstly, there are particular concentrations in non-metropolitan coastal resort areas. This is particularly noticeable along the northern and southern coast of New South Wales and in southeastern Queensland with the growth fuelled particularly by retirement migration toward attractive environment and equable climates. A particular feature of these developments has been widespread patterns of people taking up more or less full-time residence in their former holiday homes upon retirement. - 24 - A similar ‘holiday shack’ associated development can be identified along rivers, especially the River Murray. Another pattern associated with older people seeking out attractive environments upon retirement, once they are freed from the necessity of living within commuting range of their workplace, is the growth of retirement communities in favourable inland ecological areas near the larger cities. Many country towns have an above average concentration of older people. This often reflects a pattern of older people retiring off of farm properties into nearby towns which allows them to maintain (and perhaps even enhance) existing local social networks and ‘keep an eye’ on their children who have taken over the farm. The remainder of non-metropolitan LGAs with above average concentrations of older people are found in the more closely settled agricultural areas of the respective states. These also tend to be the longest settled agricultural parts of those states although located beyond the commuting zones of the largest cities, they tend to be the most accessible of the purely agricultural areas to the capital cities. Here the above average levels of ageing are less a function of inmovement of older persons than of the heavy outmovement of younger adults from these older areas – one of the stereotypical characteristics of rural depopulation is an ‘old’ population structure. In particular localities (especially in seaside, riverside and other scenically attractive medium sized country towns) this effect may be supplemented by inmigration of retirees, especially those moving off of farms. Within non metropolitan areas there is a strong likelihood that the growth of the aged population will be more influenced by internal migration than is the case within metropolitan areas where most people age in place after retirement. Figure 11 shows the net migration by age and sex for areas outside of the Capital Cities in Australia for the 2006-11 period. This - 25 - shows definitely that there was a net migration gain in these areas and the pre-retirement and retirement ages. This overwhelmingly reflects retirement migration out of Australia’s capitals. To what extent baby boomers make these moves to coastal areas and other favoured non-metropolitan locations will influence the growth of the aged population outside of cities. Currently through there is a higher percentage of older Australians living outside the capitals than is the case for the total population and the aged population is growing faster outside the capitals than within them.

We can be very certain about the future size of this population, many of the characteristics of the future aged population are also fixed and many are currently living where they will be living when they enter old age. There are some uncertainties and these will strongly be influenced by policy interventions. Some of the most important of these are: - 26 - How healthy will baby boomers be in old age? The signs are not good here but real efforts to reduce obesity among baby boomers could have massive dividends in improving their lives in old age but substantially reducing demands on the health and aged care systems. How many baby boomers will move as they approach or enter retirement? This will be influenced by whether or not they continue working into old age, the availability of alternative housing options, patterns of partnering among baby boomers, etc. What will be the preferences of baby boomers for housing – both while they are fully independent and when they need care? A crucial element relates to what it means for the aged care workforce. There is a need not only to focus on the changing demography of the aged population but also on the workers involved in the industry proving support to them. In this respect the Productivity Commission (2011) has calculated the projections in Table 20 and this suggests that there will be a more than doubling of demand in the next two decades. Table 20: Source: Projections of Aged Care Workforce Demand Productivity Commission 2011 2010 2020 2030 2040 2050 Direct care workers (FTE workers) 85,000 107,000 157,000 254,000 353,000 Direct care workers (total workers) 144,000 182,000 266,000 431,000 598,000 189,000 239,000 349,000 565,000 785,000 Direct care workers (FTE workers) 11,000 41,000 57,000 82,000 102,000 Direct care workers (total workers) 19,000 66,000 92,000 132,000 164,000 22,000 78,000 109,000 156,000 194,000 212,000 317,000 459,000 721,000 979,000 Residential Care Total residential care workforce (direct and support workers) Community Care Total community care workforce (direct and support workers) Total Workforce Requirement a a Total workforce requirement may not reflect sum of components due to rounding. - 27 - The picture of substantial growth in the aged care sector is in broad outline a very clear one. The overall dimensions of growth are determined by demography. It is the detail which needs to be clarified in terms of how the older baby boomer population is segmented into meaningful groups in terms of their demand and need for particular type of housing and a range of services and where they will be living. - 28 - References Access Economics, 2011.
