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.
In: State of the world 1985. A Worldwatch Institute report on progress toward a sustainable society [by] Lester R. Brown, Edward C. Wolf, Linda Starke, William U. Chandler, Christopher Flavin, Sandra Postel, Cynthia Pollack. New York, New York, W.W. Norton, 1985. 200-21.The demographic contrasts of the 1980s are placing considerable stress on the international economic system and on national political structures. Runaway population growth is indirectly fueling the debt crisis by increasing the need for imported food and other basic commodities. Low fertility countries are food aid donors, and the higher fertility countries are the recipients. In most countries with high fertility, food production per person is either stagnant or declining. Population policy is becoming a priority of national governments and international development agencies. This discussion reviews what has happened since the UN's first World Population Conference in 1974 in Bucharest, fertility trends and projections, social influences on fertility, advances in contraceptive technology, and 2 major family planning gaps -- the gap between the demand for family planning services and their availability and the gap between the societal need to slow population growth quickly and the private interests of couples in doing so. The official purpose of the 1984 UN International Conference on Population convened in Mexico City, in which 149 countries participated, was to review the world population plan of action adopted at Bucharest. In Bucharest there had been a wide political schism between the representatives of industrial countries, who pushed for an increase in 3rd world family planning efforts, and those from developing countries, whose leaders argued that social and economic progress was the key to slowing population growth. In Mexico City this division had virtually disappeared. Many things had happened since Bucharest to foster the attitude change. The costly consequences of continuing rapid population growth that had seemed so theoretical in the 1974 debate were becoming increasingly real for many. World population in 1984 totaled 4.76 billion, an increase of some 81 million in 1 year. The population projections for the industrial countries and East Asia seem reasonable enough in terms of what local resource and life support systems can sustain, but those for much of the rest of the world do not. Most demographers are still projecting that world population will continue growing until it reaches some 10 billion, but that most of the 5.3 billion additional people will be concentrated in a few regions, principally the Indian subcontinent, the Middle East, Africa, and Latin America. What demographers are projecting does not mesh with what ecologists or agronomists are reporting. In too many countries ecological deterioration is translating into economic decline which in turn leads to social disintegration. The social indicator that correlates most closely with declining fertility across the whole range of development is the education of women. Worldwide, sterilization protects more couples from unwanted pregnancy than any other practice. Oral contraceptives rank second. The rapid growth now confronting the world community argues for effective family planning programs.
