Tokyo, Japan, Ministry of Health and Welfare, Institute of Population Problems, 1991 Feb 22. , 143 p. (Research Series No. 267)According to the UN Population Projections of 1990, the world population of 5 billion, 292 million, 200 thousand in 1990 will reach 6 billion, 260 million, 800 thousand in the year 2000 with an annual increase rate of about 100 million. 94% of the increase will be in developing countries. In the year, 2025, the world population will be 8 billion, 54 million. 96% of the increase between 2000 and 2025 will also be in developing countries. The ratio of the population of developing countries to the world population was 77% in 1990 and will be 80% and 84% in 2000 and 2025 respectively. The new UN projections added about 10 million to the previous figure projected for 2000 and 38 million to the same for 2025. The World Bank's Projections are 6 billion 204 for the year 2000 and 8 billion 15 million for 2025. Their figures are slightly smaller than UN figures. Their data also include Taiwan and socio-economic group specific population, both of which are not found in UN data. In 2150, the world population is projected to be 11 billion 499 million with all of the increase from 2050 to 150 taking place in the developing region. According to high medium, and low variants in the UN projections, world population in 2020 will be 9 billion 400 million, 8 billion 500 million, and 7 billion 600 million respectively. Asian population, which constituted 55% of the world population in 1950, will be 59% in 1990. Since 1980, Southern Asia and Africa have seen the highest increase rates. African population, which was 9% in 1950 and 12% in 1990, will increase to 19% in 2025. After 2000, population in some regions of Europe will decrease as it will in Japan after 2010. The world population as a whole changed from high fertility and high mortality to high fertility and low mortality and then to low fertility and low mortality. In 1990, the population pyramid of developing nations was expansive triangular, while that of highly industrialized nations was constructive high rise or near stationary. The age specific ratio in industrialized regions will be 13% in 2000 and 18-19% in 2025.
ANNALS OF THE NEW YORK ACADEMY OF SCIENCES. 1991; 626:1-10.WHO defines reproductive health as people having the ability to reproduce, to regulate fertility, and to practice and enjoy sexual relationships. It also means safe pregnancy, child birth, contraceptives, and sex. Procreation should include a successful outcome as indicated by infant and child survival, growth, and healthy development. 60-80 million infertile couples live in the world. Core infertility, i.e., unpreventable and untreatable infertility, ranges from 3% to 5%. Sexually transmitted diseases, aseptic abortion, or puerperal infection are common causes of acquired infertility. Sub-Saharan Africa has the highest prevalence of acquired infertility. In 1983, the world contraceptive use rate stood at 51% with the developed countries having the highest rate (70%) and Africa the lowest rate (14%). About 40 countries in Africa and the Arabian Peninsula practice female circumcision. The percent of low birth weight infants is greater in developing countries than in developed countries (17% vs. 6.8%). Intrauterine growth retardation is responsible for most low birth weight infants in developing countries while in developed countries it is premature birth. About 15 million infants and children die each year. Maternal mortality risk is highest in developing countries especially those in Africa (1:21) and lowest in developed countries (1:9850). Sexually transmitted diseases continue to be a major problem in the world especially in developing countries. Chlamydia afflicts 50 million people each year. The proportion of women with AIDS is growing so that between the 1980s and 1990s it will grow between 25% and 50%. More available contraceptive choices enhance safety in fertility regulation. Socioeconomic conditions that determine reproductive health are poverty, literacy, and women's status. Sexual behavior, reproductive behavior, breast feeding, and smoking are life style determinants of reproductive health. Availability, utilization, and efficiency of health care services and level of medical knowledge also determine women's reproductive health.
New York, New York, United Nations Population Fund [UNFPA], 1991. , 48 p.Developing countries increased their commitment to implement population policies in the late 1980s and early 1990s with the support and guidance of UNFPA. These policies focused on improving, expanding, and integrating voluntary family planning services into social development. 1985-1990 data revealed that fertility began to fall in all major regions of the world. For example, fertility fell most in East Asia from 6.1-2.7 (1960-1965 to 1985-1990). This could not have occurred without strong, well managed family planning programs. Yet population continued to grow. This rapid growth hampered health and education, worsened environmental pollution and urban growth, and promoted political and economic instability. Therefore it is critical for developing countries to reduce fertility from 3.8-3.3 and increase in family planning use from 51-59% by 2000. These targets cannot be achieved, however, without government commitments to improving the status of women and maternal and child health and providing basic needs. They must also include promoting child survival and education. Further people must be able to make personal choices in their lives, especially in contraceptive use. Women are encouraged to participate in development and primary health care in Kerala State, India and Sri Lanka. The governments also provide effective family planning services. These approaches contributed significantly to improvements in fertility, literacy, and infant mortality. To achieve the targets, UNFPA estimated a doubling of funding to $9 billion/year by 2000. Lower costs can be achieved by involving the commercial sector and nongovernmental organizations, building in cost recovery in the distribution system of contraceptives, operating family planning services efficiently, and mixing contraceptive methods.
