PEOPLE. 1987; 14(2):25.At some time during 1987 the 5 billionth person will be born according to the UN Population Division. If the UN media variant projections are accurate, the world will pass the 5 billion mark between April and July 1987. The world's population is expected to total 6 billion in 1999, 7 billion in 2010, and 8 billion in 2022. At the time the population reaches 5 billion, the annual global rate of population growth is estimated to be 1.63%. According to the medium-variant projections, the growth rate will drop to about 1.4% by 2000 and to less than 1% by 2025. Despite the relatively recent decline in the growth rate of the world, the annual increment to the total population continues to increase. Half of the world's 5 billion people in 1987 will be under age 24 and close to 1/3 will be children under age 15. 1 billion persons will be in the 15-24 age group; about 1 of 10 will be age 60 or older. 1 of 25 persons will be 70 years or older. By the middle of 1987, 42% of the world's population, or 2.1 billion people, will reside in urban areas, and it is anticipated that more than half of the world's 7 million people will live in towns and cities by 2010.
In: Population prospects in developing countries: structure and dynamics, edited by Atsushi Otomo, Haruo Sagaza, and Yasuko Hayase. Tokyo, Japan, Institute of Developing Economies, 1985. 1-15, 325. (I.D.E. Statistical Data Series No. 46)This discussion covers the prospects of population growth in Asian countries, prospects of changes in sex-age structures in Asian countries, and the effect of urbanization on national population growth in developing countries. According to the UN estimates assessed in 1980, size of total population of Asian countries recorded 2580 million in 1980, which accounted for 58.2% of total population of the world. As it had shown 1390 million, accounting for 55.1% of the world population in 1950, it grew at a higher annual increase rate of 2.08% than that of 1.90% for the world average during the 30 years. On the basis of the UN population projections assessed in 1980 (medium variant), the world population attains 6121 million by 2000, and Asian population records 3555 million, which is 58.0% of the total population of the world and which is a slightly smaller share than in 1980. The population of East Asia shows 1475 million and that of South Asia 2077 million. During 20 years after 1980, the population growth becomes much faster in South Asia than in East Asia. After 1980 the population growth rate in Asia as well as on the world average shows a declining trend. In Asia it indicates 1.72% for 1980-90 and 1.50% for 1990-2000, whereas on the world average it shows 1.76% and 1.49%, respectively. The population density for Asia showing 94 persons per square kilometer, slightly lower than that of Europe (99 persons) as of 1980, records 129 persons per square kilometer and exceeds that of Europe (105 persons) in 2000. According to the UN estimates assessed in 1980, the sex ratio for the world average indicates 100.7 males/100 females as of 1980, and it shows 104.1 for Asia. This is higher than that for the average of developing countries (103.2). In the year 2000 it is observed generally in the UN projections that the countries with a sex ratio of 100 and over as of 1980 show a decrease but those with the ratio smaller than 100 record an increase. Almost all Asian countries are projected to indicate a decrease in the proportion of population aged 0-14 against the increases in that aged 15-64 and in that aged 65 and older between 1980-2000. In 1980 the proportion of population aged 0-14 showed more than 40.0% in most of the Asian countries. In the year 2000 almost all the countries in East Asia and Eastern South Asia indicate larger than 60.0% in the proportion of adult population. Urbanization brings about the effects of reducing the speed of increase in a national population and of causing significant changes in sex and age structures of the national population. Considering the future acceleration of urbanization in Asian countries, the prospects of growth and changes in sex and age structures of populations in Asian countries may need to be revised from the standpoint of subnational population changes.
Action by the United Nations to implement the recommendations of the World Population Conference, 1974: monitoring of population trends and policies.
New York, New York, United Nations, 1984 Dec. 10. 15 p. (E/CN.9/1984/2/Add.1)Pursuant to the recommendation of the World Population Plan of Action adopted in 1974, which was reaffirmed by the International Conference on Population in 1984, the United Nations has been undertaking a biennial review of population trends and policies. At the 22nd session of the Population Commission, held in January 1984, the Commission requested the Secretary-General to prepare an addendum to the concise report on monitoring of population trends and policies for the 23rd session, bearing in mind the relatively short time span since the preparation of the last such report. The purpose of the present document is to provide the Population Commission with such information to facilitate its deliberation on the agenda item. Analyses show that the gradual slow-down of global population growth is still holding with the present rate estimated at 1.65%/year, down from 2% during the 1960s. Declines have occurred in both the developed and the developing countries. Regional diversity of population trends have been so large that an overall global assessment seems almost irrelevant for policy consideration at national levels. The future population growth rate is expected to decline slower than it did in the past 15 years unless population policies change significantly. During the 1980-85 period the working age population (15-64 years) in the developing countries is estimated to have increased, on the average, at an annual rate of 2.8%, the elderly population (60 and over) at 3% and women in the reproductive ages (15-49 years) at 2.9%. The most urgent problem for many developing countries is perhaps the continuing very rapid increase of the working age population. The aging of the population, which bears significant policy implications, is among the most salient features of population change in the world, except for Africa. Fertility rates in most developed countries continue to fluctuate at low levels. No current data on developing country rates are available. An overall improvement in mortality in most countries is noted. A high rate of urban population growth in developing countries is a tremendous problem facing these countries. International migration, social and economic implications, demographic perceptions and governmental policies are summarized. National sovereignty, human rights, cultural values and peace are stressed as important factors in population policies. Women's status is discussed as playing a role in population change.
