POPULATION EXPLOSION, PLANNING & SOLUTION IN INDIAN PERCEPTIVE. 1 Submitted by Ashita Elizabeth Abby INTRODUCTION The literal meaning of population is the whole number of people or inhabitants in a country or region .“WEBSTERS” dictionary & literal meaning of population explosion is a pyramiding of a biological population. As number of people in a pyramid increases. so do the problems related to increased population. 2 Demography is the scientific study of human population. it focuses its attention on three readily observable human phenomena 1)changes in population size 2)the composition of the population 3)the distribution of population in space It deals with 5 demographic processes namely fertility, mortality, marriage, migration and social mobility. these 5 processes are continuously at work within a population deterging size, composition and distribution. 3 DEMOGRAPHIC CYCLE The history of world population since 1650 suggests that there is a demographic cycle of 5 stages through which a nation posses 1. First stage- this stage is characterized by a high birth rate and a high death which cancel each other & the population remains stationary. India was in this stage till 1920. 2. Second stage- the death rate begins to decline ,while the birth rate remains unchanged. Many countries in South Asia & Africa are in this phase. Birth rates have increased in some of these countries possibly as a result of improved health conditions and4 shortening periods of breast feeding. 3. Third stage- the death rate declines still further, and the birth rate tends to fall. The population continues to grow because births exceed deaths. India has entered this phase 4. Fourth stage- this stage is characterized by a low birth and low death rate with the result that the population becomes stationary. Zero population growth has already been recorded in Austria during 1980-85.Growth rates as little as 0.1 were recorded in UK, Denmark, Sweden & Belgium during 1980-85. 5 5. Fifth stage (declining)-the population begins because birth rate is lower than the death rate. Some east European countries, notably Germany and Hungary are experiencing this stage 6 7 HISTORY OF CONCERN Concern about over population is relatively recent in origin throughout history, populations have grown slowly despite high birth rates due to the population reducing effects of war, plaque and high infant mortality During 750 years because the industrial revolution, the world’s population hardly increased, remaining under 250 million. By the beginning of 19th century the world population had grown to a billion individuals and intellectuals such as THOMAS MATHEW & physiocratic economists predicted that mankind would outgrow its available resources. since a finite amount of land was incapable of supporting an endlessly increasing population. 8 WORLD POPULATION TRENDS At the beginning of the Christian era nearly 2,000years ago world population was estimated to be around 250 million .It required all the human history up to the year 1800 for the world population to reach one billion 9 About three fourths of the world’s population lives in the developing countries. Although in terms of population U SA ranks third in the world after India ,there is a yawning gap of 146million between the population of these two countries .The united nations had estimated that world’s population grew at an annual rate of 1.4% during 1990-2000,china registered a much lower annual growth rate of population during 1990-2000,as compared to India. In fact the growth rate of china is now very much comparable to that of USA. 10 BIRTH & DEATH RATE The world’s birth rate fell below 30 for the first time around 1975 and had declined to about 22 during 2002.In most of the world the decline reflected falling birth rate and a global trend toward smaller families. The outstanding e.gs are Singapore and Thailand. In Singapore in 32 years the birth rate fell from 23 per thousand in 1970 to 10 in 2002;and in Thailand from 37 to 18 during the same period. 11 In all these countries ,key factors in fertility decline included changes in Government attitude towards growth. The spread of education. increased availability of contraception and the extension of service offered through family planning programmes .As well as the marked change in marriage patterns. 12 GROWTH RATES When the crude death rate is subtracted from the crude birth rate, the net residual is the current growth rate The world population growth rate was at a near its peak, around 1970,when the human population from by an estimated 1.92% The most recent date show a slight decline since then to 1,4%in 2000 13 Approximately 95% of this growth is occurring in the developing countries Currently one third of the world's population is under the age 15 and will soon enter the reproductive bracket, giving more potential for population growth The UNFPA estimates that world population is most likely to reach 10 billion people by 2050 and 20.7 billion a century later 14 15 DEMOGRAPHIC TRENDS IN INDIA India’s population has been steadily increasing since 1921.the year 1921 is called the ”big divide” because the absolute no. of people added to the population during each decade has been on the increase since 1921 India’s population is currently increasing at the rate of 16 million each year 16 AGE PYRAMIDS The age structure of a population is represented as ‘age pyramid’. A vivid contrast may be seen in the age distribution of men and women in India & in Switzerland The age pyramid of India is typical under developed countries with a broad base and a tapering top. In the developed countries as in Switzerland, the pyramid generally shows a bulge in the middle and has a narrower base. 17 18 SEX RATIO Sex ratios is defined as “the no. of females per 1000males” One of the basic demographic characteristics of the population is the sex composition . In any study of population analysis of the sex composition plays a vital role. The sex composition of the population is affected by the differentials in mortality conditions of males and females ,sex selective migration and sex ratio at birth. 19 The sex ratio in India has been generally adverse to women i.e. the no. of women per 1,000 men has generally been less than 1,000. apart from being adverse to women, the sex ratio has also declined over the decades. Kerala has a sex ratio of 1,058 females per 1,000 males in 2001.it is the only state with a sex ratio favorable to females 20 DEPENDENCY RATIO • • The proportion of persons above 65 years of age and children below 15 years of age are considered to be dependent on the economically productive age group 15-64yrs,the ratio of the combined age groups 0-14yrs plus 65 yrs and above to the 15-65yr group is referred to as the total dependency ratio. It is also referred to as the societal dependency ratio and reflects the need for a society to provide to their younger and older population groups. 21 The dependency ratio can be subdivided into young age dependency 0-14yr and the old age dependency ratio 65yrs and more. These ratios are relatively crude ,since they do not take into consideration elderly or young persons who are employed or working age persons who are unemployed 22 23 FAMILY SIZE While in common parlance ,family size refers to the total no. of persons in a family in demography, family size means the total no. of children a woman has borne at a point in time The completed family size indicates the total no. of children borne by a woman ,which is generally assumed to be between 15 and 45yrs The total fertility rate gives the approximate magnitude of completed family size 24 The family size depends upon : a) Duration of marriage b) Education of the couple c) The no. of live births and living children d) Preference to male children e) Desired family size 25 The family planning programmers campaign is currently based on the theme of a two-child norm, with a view to reach the long term demographic goal of NRR=1 Family planning involves both decision regarding the desired family size and the effective limitation of fertility once that size has been reached The size decreases in family size does not appear to be due to any reduction in fertility, rather it appears to be due to the result of deliberate family planning 26 LITERACY AND EDUCATION In 1948,the declaration of human rights stated that everyone has right to education Education is a cervical element in economic and social development, without education ,development can neither be broad based on sustained Spread of literacy is generally associated with modernization urbanization, industrialization, communication and commerce. It forms an important input in the overall development of individuals enabling them to comprehend this social political and cultural environment better and respond to its appropriately 27 LIFE EXPECTANCY Life expectancy or expectation of life at a given age is the average no. of years which a person of that age may expect to live according to the mortality pattern prevalent in that country Demographers consider it as one of the best indicates of a country’s level of development and of the overall health status of its population 28 Trends in life expectancy show that people are living longer and they have a right to a long life in good health, rather than one of pain and disability Health policy makers thus need to recognize this changing demographic pattern and plan for prevention and control of diseases associated with old age. 29 FERTILITY Fertility is meant the actual bearing of children, some demographers prefer to use the word natality in place of fertility Fertility depends upon several factors. the higher fertility in India is attributed to universality of marriage, lower age at marriage, low level of literacy, poor level of living ,limited use of contraceptives and traditional ways of life 30 Some of the factors are: 1 Age at marriage The age at which a female marries and enters the reproductive period of life has great impact on her fertility. The Registrar General of India collected data on fertility on a scale and found that females who marry before the age of 18 gave birth to a larger no. of children than those who married after. In India some demographers have estimated that if marriages were postponed from the age of 16 to 20-21,the no. of births would decrease by 20-30% 31 2) Duration of married life Studies indicate that 10-25% of all births occur within 1-5 years of married life,50-55% of all births within 5-15 years of married life. Births after 25 years of married life are very few. This suggests that family planning efforts should be concentrated in the first few years of married life in order to achieve tangible results 32 3) Spacing of children Studies have shown that when all births are postponed by one year in each group, there was a decline in total fertility it follows that spacing of children may have a significant impact on the general reduction in the fertility rates. 4) Education There is a inverse association between fertility and educational status .the national family health survey 2 shows that fertility rate is 1.5 children higher for illiterate women than for women with a least a 33 high school education 5) Economic status Operational research studies support the hypothesis that economic status bears an inverse relationship with fertility, the total no. of children born declines with an increase in per capita expenditure of the household. the world population conference at Bucharest in fact stressed that economic development is the best contraceptive .It will take care of population growth and bring about reductions in fertility 34 6) Caste and religion Muslims have a higher fertility than Hindus. The national family health survey 2 reported a total fertility rate of 3.59 among Muslims as compared to 2.78 among Hindus. The total fertility rate among Christians was found to be 2.44,among lower castes seem to have a higher fertility than the higher castes 7) Nutrition There appears to be some relationship between nutritional status and fertility levels. Virtually all well fed societies have low fertility and poorly fed societies high fertility. The effect nutrition on fertility is largely indirect 35 8) Family planning Family planning is another important factor in fertility reduction. In a no. of developing countries , family planning has been a key factor in declining fertility. Family planning programme can be initiated rapidly and require only limited resources as compared to other factors 36 9) Other factors Fertility is affected by a no. of physical, biological, social and cultural factors, such as place of women in society value of children in society, widow remarriage, breast feeding, customs and beliefs, industrialization and urbanization better health conditions, housing, opportunities for women and local community involvement. Attention to these factors requires long term programmes and vast sums of money. 37 FERTILITY TRENDS Researchers indicate that the level of fertility in India is beginning to decline. The crude birth rate which was about 49 per thousand population during 1901-2011 has declined to a about 31.3 per thousand population in 1991and 25 per thousand population in 2002. 38 FAMILY PLANNING There are several definitions of family planning, an expert committee in 1971 of the WHO defined family planning as “a way of thinking and living that is adopted voluntarily, upon the basis of knowledge, attitudes and responsible decisions by individuals and couples”. Another expert committee defined and described family planning as follows “family planning refers to practices that help individuals or couples to attain certain objectives: 39 a) b) c) d) e) To avoid unwanted births To bring about wanted births To regulate the intervals between pregnancies To control the time at which births occur in relation to the ages of the parent To determine the no. of children in the family 40 BASIC HUMAN RIGHTS The world conference of international women’s year in 1975 also declared ”the right of women to decide freely and responsibly on the number and spacing of their children and to have access to the information and means to enable them to exercise at right”. Thus during the past few years, family planning has emerged from whispers in private quarters to the focus of international concern as a basic human right and a component if family health and social welfare. 41 SCOPE OF FAMILY PLANNING SERVICES A WHO expert committee has stated that family planning includes in the purview 1. The proper spacing and limitation for births 2. Advice on sterility 3. Education for parent hood 4. Sex education 5. Screening foe pathological conditions related to the reproductive system 6. Genetic counseling 7. Premarital consultation and examination 8. Carrying out pregnancy tests 42 Marriage counseling 10. The preparation of couples for the arrival of their first child 11. Providing adoption services These activities vary from country according to national objectives and polices with regard to family planning this is the modern concept of family planning. 9. 43 HEALTH ASPECTS OF FAMILY PLANNING Family planning and health have a two way relationship. The principle planning health outcomes of family planning were listed and discussed by a who scientific group on health aspects of family planning these can be summarized under • Women’s health: maternal mortality of women of child bearing age nutritional status, preventable complications of pregnancy and abortion. 44 Fetal health: fetal mortality, abnormal development • Infant and child health: neonatal, infant and preschool mortality health of the infant • 45 THE WELFARE CONCEPT Family planning is associated with numerous misconceptions one of them is its strong association in the minds of people with sterilization. Other equate it with birth control. The recognition of its welfare concept came only a decade and half after its inception. When it was named Family welfare programme The concept is very comprehensive and is basically related to quality of life. The family welfare programme aims at achieving a higher end that is to improve the quality of life of the people 46 NATIONAL POPULATION POLICY 2000 In April 1976 India formed its first- “ national population policy”. It called for an increase in the legal minimum age of marriage from 15 to 18 for females and from 18 to 21 for males. However, for most part, the 1976 statement become irrelevant and the policy was modified in 1971. New policy statement reiterated the importance of small family norm without compulsion and changed the programme title to ‘family welfare programme’ 47 “national population policy 2000” is the latest in this series it reaffirms the commitment of the government towards target free approach in administering family planning services. It gives informed choice of the people to voluntarily avail the reproductive health care services The new NPP 2000 deals with women education, empowering women for improved health and nutrition, child survival and health, adolescent’s health 48 CONTRACEPTIVE METHODS 49 The preventive methods to help women to avoid unwanted pregnancies. They include all temporary and permanent measures to prevent pregnancy resulting from coitus. The success of any contraceptive method depends not only on its effectiveness in preventing pregnancy but on the rate of continuation of its proper use. 50 CLASSIFICATION 1) Spacing methods a) Barrier methods i) physical methods ii) chemical methods iii)combined methods b) Intra uterine devices Hormonal methods Post-conceptional methods miscellaneous 51 2) Terminal methods i) male sterilization ii) female sterilization 52 BARRIER METHODS The main advantage is the absence of side effects associated with the pill and IUD. The non contraceptive advantage include some protection from sexually transmitted diseases, a reduction in the incidence of pelvic inflammatory disease and possibly some protection from the risk of cervical cancer. They are less effective if they are used consistently and carefully. 53 PHYSICAL METHODS Condom it is most common barrier device used by males. In addition to preventing pregnancy, condom protects both men and women from sexually transmitted diseases. Advantages a) They are easily available b) Safe and inexpensive c) Easy to use d) No side effects 1) 54 The main limitation of condom is that many men do not use them regularly or carefully, even when the risk of unwanted pregnancy or sexually transmitted diseases is high. 55 2) Diaphragm is a vaginal barrier. also known as Dutch Cap It is a shallow cup made up of synthetic rubber or plastic material. Advantages Total absence of risks and medical contraindications Disadvantages Initially a physician or other trained person will be needed to demonstrate this technique. If this is left in the vagina for an extended period, there is a remote possibility of a toxic syndrome. 56 3) Vaginal sponge It is a small polyurethane foam sponge measuring 5cm x2.5cm saturated with the spermicide.The sponge is less effective . 57 Diaphragm Vaginal ring 58 CHEMICAL METHODS Four categories: a) Foams : foam tablets, foam aerosols b) Creams, jellies and pastes c) Suppositories : inserted manually d) Soluble films Drawbacks a) They have a high risk failure rate b) They must be used almost immediately before intercourse c) They may cause mild burning or irritation. 59 INTRA-UTERINE DEVICES The most widely used IUD devices are copper T20,copper T-200,LNG-20 etc.. Advantages no complex procedures Inexpensive Highest continuation rate Insertion takes only a few minutes Once inserted it takes long as required 60 Disadvantages Absolute a) Suspected pregnancy b) Pelvic inflammatory disease c) Vaginal bleeding d) Cancer of cervix, uterus Relative a)Anaemia b)Unmotivated person 61 Side effects and complications 1) Bleeding 2) Pain 3) Pelvic infection 4) Pregnancy 5) Cancer 6) Mortality 62 HORMONAL CONTRACEPTIVES Classification: 1) Combined pill 2) Progestogen only pill 3) Once-a-month pill 4) Male pill 63 TERMINATION OF PREGNACY Safe period Also known as calendar method.. 64 Drawbacks 1) A woman’s menstrual cycle are not always regular; so its difficult to predict the safe period. 2) It is only possible for this method to be used by educated and responsible couples with motivation 3) This method is not applicable during the post natal period 65 TERMINAL METHODS Sterilization offers many advantages over other contraceptive methods It is one time method. It does not require sustained motivations of the user for its effectiveness. The risk of complications is small if the procedure is performed according to accepted medical standards 66 Male sterilization [vasectomy] It have no risk of mortality. Following vasectomy sperm production and hormone output are not affected. Female sterilization [tubectomy] It can be done as interval procedure or at the time of abortion. Two procedures have become most common 1) Laparoscopy 2) Minilop operation 67 NATIONAL FAMILY WELFARE PROGRAMME India launched a nation-wide family planning programme in 1952,making it the first country in the world. In April 1976,the country framed its first “National population policy". in June 1977 government that came into power formulated a new population policy. The family welfare programme in India has come a long way and holds forth the promise that in the not very distant future it may be accepted as a way of life by most people.. The programme now aim at achieving a higher end and that is, to improve in conjunctions with other development programmes, the quality of life of the people. 68 69
