The sex and age distributions of population. The 1990 revision of the United Nations global population estimates and projections.
New York, New York, United Nations, 1991. viii, 391 p. (Population Studies No. 122; ST/ESA/SER.A/122)This statistical report includes the estimated and projected age distribution of the population based on high, medium, and low variants for 152 countries with populations greater than 300,000 between 1950 and 2025 in 5-year intervals. A world total as well as by continents and subregions are available along with the spatial groups; least developed countries, less developed regions (excluding China), the Economic Commission for Africa, Latin America and the Caribbean, Asia, and the Pacific, Western Asia, and sub-Saharan Africa. Grouped data reflect countries with populations both greater than and less than 300,000. This revision was begun in 1988 and completed in 1990 by the UN Population Division of the International Economic and Social Affairs Department in conjunction with other UN regional commissions and the Statistical Office. A discussion of methods and data used for these estimates, a summary of findings, and selected demographic indicators will be available in World Population Prospects, 1990, and in summary form in the UN World Population Chart, 1990. A magnetic tape and diskettes of these data are available on request for purchase.
New York, New York, United Nations, 1990. xiii, 420 p. (ST/ESA/SER.R/98)2 groups expressed a need for this 2nd edition volume of stable population age distributions. Easily accessible information on the effect of demographic changes upon age distributions and dependency burdens is needed by planners of developing countries, while demographers are interested in construction demographic parameters under conditions of deficient data. A set of model stable age distributions, a series of intrinsic growth rates from 0-4%, intrinsic birth and death rates, percentages of populations in the 15-59 age groups, and child, elderly, and total dependency rates are therefore presented in this volume for the Latin American, Chilean, South Asian, Far East Asian, and General patterns of mortality. The Latin American pattern exhibits high mortality in the infant, childhood, and young adult years, with lower levels in the older ages. The Chilean pattern is one of extremely high infant mortality relative to general childhood mortality, while the South Asian pattern shows extremely high mortality under age 15 and over age 55. Low mortality is evidenced in the prime ages. The Far Eastern pattern exhibits relatively low mortality at younger ages, with high death rates at older ages. The General pattern is an average of these 4. Rates are defined, then calculated in an improved manner. UN model life table characteristics are also discussed and presented in an easier-to-read format. 420 pages of tables constitute the bulk of the volume.
An examination of the population structure of Liberia within the framework of the Kilimanjaro and Mexico City Recommendations on Population and Development: policy implications and mechanism.
In: The 1984 International Conference on Population: the Liberian experience, [compiled by] Liberia. Ministry of Planning and Economic Affairs. Monrovia, Liberia, Ministry of Planning and Economic Affairs, . 111-36.The age and sex composition and distribution of the population of Liberia as affected by fertility, mortality, morbidity, migration, and development are examined within the framework of the Kilimanjaro Program of Action and recommendations of the International Conference on Population held in Mexico City. The data used are projections (1984-85) published in the 2nd Socio-Economic Development Plan, 1980. The population of Liberia is increasing at the rate of 3.5% and will double in 23.1 years. 60% of the population is under 20 and 2% over 75. Projected life expectancy is 55.5 years for women and 53.4 years for men. The population is characterized by high age dependency; 47.1% of the people are under 15 and 2.9% are over 64, so that half of the population consists of dependent age groups, primarily the school-age children (6-11 years). If these children are to enter the labor force, it is estimated that 19,500 jobs will have to be created to employ them. Moreover, fertility remains at its constant high level (3.5%), so, as mortality declines, the economic problem becomes acute. Furthermore, high fertility is accompanied by high infant and maternal mortality. High infant mortality causes couples in rural areas to have more children. These interdependent circumstances point up the need for family planning, more adequate health care delivery systems, and increasing the number of schools to eradicate illiteracy, which is currently at 80%. Integrated planning and development strategies and appropriate allotment of funds must become part of the government's policy if the Kilimanjaro and Mexico City recommendations are to be implemented.
In: The 1984 International Conference on Population: the Liberian experience, [compiled by] Liberia. Ministry of Planning and Economic Affairs. Monrovia, Liberia, Ministry of Planning and Economic Affairs, . 9-17.The purpose of the National Seminar on Population is to disseminate in Liberia the results of the World Population Conference held in Mexico City in August 1984. Due to the complex interrelationships between population and development, one must conclude that rapid population growth has an adverse effect on development. Liberia has a high level of fertility (48-51 lives births per 1000 population) and a high mortality (18 per 1000 population). One result of these population trends is that the population is youthful, about 50% of the people being under 18. This high growth potential means that in future the resources necessary to support the population will be scarcer. Secondly, increasing rural to urban migration means that the cities will have more people than they have jobs, housing, education, or health facilities to support them and that the rural areas will be depopulated with attendant lowered agricultural production and rural poverty. Education is at least partly responsible for the rural-urban migration because it alerts young people to the increasing opportunities in the towns. The current trend of increasing fertility and declining mortality means decreased economic growth and a lower standard of living. To reduce this trend people must be made aware of the necessity to lower the birth rate as well as of the means to do it. People regard a large family as a status symbol and children as a source of labor and support in old age. These attitudes will not change until people trust that the Government is committed to the socioeconomic changes that will make practicable the shift from large households with low productivity to small families with high productivity. As part of this effort, the National Committee on Population is being expanded into a National Population Commission, responsible for coordinating population programs and drafting a national population policy.
In: Population strategy in Asia. The Second Asian Population Conference, Tokyo, November 1972. Report, declaration and selected papers, [compiled by] United Nations Economic Commission for Asia and the Far East [ECAFE]. Bangkok, Thailand, ECAFE, 1974 Jun. 69-130. (Asian Population Study Series No. 28; E/C.N.11/1152)The Economic Commission for Asia and the Far East (ECAFE) region currently includes 31 countries and territories. Since the first Asian Population Conference in 1963, there has been greater recognition of the adverse effects of rapid population growth on national development and on the standard of living of individual family units. By the year 2000, the population of the ECAFE region is expected to almost equal the total for the world in 1970, despite significantly slowed population growth in the East Asia subregion. During the periods 1900-1950 and 1950-2000, the average annual rates of growth for the population of the ECAFE region are estimated at 0.7% and 2.0%, respectively. The 4 largest countries in the region--China, India, Indonesia, and Japan--together hold 78% of the region's total population. Even in the countries where there has been a decline in fertility, it has not been sufficient to offset the effects of corresponding declines in mortality. The 1950 population of each country, except for China and Japan, will at least double itself by the year 2000. The number of preschool-aged children is expected to reach 356 million by 1980 and there will be 609 million school-aged children. Children ages 0-14 years currently comprise about 40% of the total population of the ECAFE region, producing a high dependency burden. The female population in the reproductive age group will grow from 474 million in 1970 to 593 million in 1980, implying that the fertility potential of the region will be accelerated. In addition, the population of persons aged 60 years and over will increase from 117 million in 1970 to 158 million in 1980, requiring significant investments in health facilities and social security. The urban population in the region is expected to increase from 25% in 1970 to 45% by 2000. Despite widespread awareness of the interrelation of population and development, no common approach among demographers, family plannes, and economic plannes has emerged.
New York, New York, United Nations, 1987. ix, 385 p. (ST/ESA/SER.R/70.)The report presents the estimated and projected sex and age distributions according to the medium, high, and low variants for population growth for 1950-2025 for countries and areas generally with a population of 300,000 and over in 1980. The data for smaller countries or areas are included in the regional population totals and are not given separately. This report supplements the report on the WORLD POPULATION PROSPECTS: ESTIMATES AND PROJECTIONS AS ASSESSED IN 1984, which presents methods, data, assumptions, and a summary of major findings of the estimates and projections, as well as selected demographic indicators for every country or area of the world. The sex and age distributions of population in this report are based on the 10th round of the global demographic assessments undertaken by the UN Secretariat. They are derived from data that were available to the UN generally by the beginning of 1985; therefore, the figures presented supercede those that were previously published by the UN.
China: long-term development issues and options. The report of a mission sent to China by the World Bank.
Baltimore, Maryland, Johns Hopkins University Press, 1985. xiii, 183 p. (World Bank Country Economic Report)This report summarizes the conclusions of a World Bank study undertaken in 1984 to identify the key development issues China is expected to face in the next 20 years. Among the areas addressed by chapters in this monograph are agricultural prospects, energy development, spatial issues, international economic strategy, managing industrial technology, human development, mobilizing financial resources, and development management. China's economic prospects are viewed as dependinding upon success in mobilizing and effectively using all available resources, especially people. This in turn will depend on sucess in reforming the system of economic management, including progress in 3 areas: 1) greater use of market regulation to stimulate innovation and efficiency; 2) stronger planning, combining indirect with direct economic control; and 3) modification and extension of social institutions and policies to maintain the fairness in distribution that is basic to socialism in the face of the greater inequality and instability that may result from market regulation and indirect controls. Over the next 2 decades, China can be expected to become a middle-income country. The government has set the goal of quadrupling the gross value of industrial and agricultural output between 1980 and 2000 and increasing per capita income from US$300 to $800. China's size and past emphasis on local self-sufficiency offer opportunities for enormous economic gains through increased specialization and trade among localities. Increased rural-urban migration seems probable and desirable, although an increase in urban services and infrastructure will be required. The expected slow rate of population increase is an important foundation for China's favorable economic growth prospects. On the other hand, it may not be desirable to hold fertility below the replacement level for very long, given the effects this would have on the population's age structure. The increase in the proportion of elderly people will be a serious social issue in the next century, and reforms of the social security system need to be considered.
In: Third Asian and Pacific Population Conference (Colombo, September 1982). Selected papers. Bangkok, Thailand, Economic and Social Commission for Asia and the Pacific, 1984. 9-40. (Asian Population Studies Series No. 58)This report summarizes the recent demographic situation and considers prospective trends and their development implications among the 39 members and associate members of the Economic and Social Commission for Asia and the Pacific (ESCAP). It presents data on the following: size, growth, and distribution of the population; age and sex structure; fertility and marriage; mortality; international migration; growth and poverty; food and nutrition; households and housing; primary health care; education; the working-age population; family planning; the elderly; and population distribution. Despite improvements in the frequency and quality of demographic data collected in recent years, big gaps continue to exist in knowledge of the demographic situation in the ESCAP region. Available evidence suggests that the population growth rate of the ESCAP region declined between 1970 and 1980, as compared with the preceding decade, but that its rate of decline was slow. Within this overall picture, there is wide variation, with the most developed countries having annual growth rates around 1% and some of the least developed countries having a figure near 3%. The main factors associated with the high growth rates are the past high levels of fertility resulting in young age structures and continuing high fertility in some countries, notably in middle south Asia. The population of countries in the ESCAP region is expected to grow from 2.5 billion in 1980, to 2.9 billion in 1990, and to 3.4 billion persons by the year 2000. This massive growth in numbers, which will be most pronounced in Middle South Asia, will occur despite projected continuing moderation in annual population growth rates. Fertility is expected to continue its downward trend, assuming a more widespread and equitable distribution of health, education, and family planning services. Mortality is expected to decline further from its current levels, where life expectancy is often at or around 50 years. In several countries, more than 10 in every 100 babies born die before their 1st birthday. The extension of primary health care services is seen as the key to reducing this figure. Rapid population growth and poverty tend to reinforce each other. Low income, lack of education, and high infant and child mortality contribute to high fertility, which in turn is associated with high rates of natural increase. High rates of natural increase feed back to depress socioeconomic development. High population growth rates and their correlates of young age structures and heavy concentrations of persons in the nonproductive ages tend to depress production and burden government expenditure with high costs for social overhead needs. Rapid population growth emerges as an important factor in the persistence of chronic undernutrition and malnutrition. It increases the magnitude of the task of improving the educational system and exacerbates the problem of substandard housing that is widely prevalent throughout Asia.
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.
Asian and Pacific Population Programme News. 1985 Mar; 14(1):2-5.In 1983, the ESCAP region added 44 million people, bringing its total population to 2600 million, which is 56% of the world population. The annual rate of population growth was 1.7% in 1983 compared to 2.4% in 1970-75. The urban population rose from 23.4% in 1970 to 26.4% in 1983, indicative of the drift from rural areas to large cities. In 1980, 12 of the world's 25 largest cities were in the ESCAP region, and there is concern about the deterioration of living conditions in these metropoles. In general, however, increasing urbanization in the developing countries of the ESCAP region has not been directly linked to increasing industrialization, possibly because of the success of rural development programs. With the exception of a few low fertility countries, a large proportion of the region's population is concentrated in the younger age groups; 50% of the population was under 22 years of age in 1983 and over 1/3 was under 15 years. In 1983, there were 69 dependents for every 100 persons of working age, although declines in the dependency ratio are projected. The region's labor force grew from 1100 million in 1970 to 1600 million in 1983; this growth has exceeded the capacity of country economies to generate adequate employment. The region is characterized by large variations in life expectancy at birth, largely reflecting differences in infant mortality rates. Whereas there are less than 10 infant deaths/1000 live births in Japan, the corresponding rates in Afghanistan and India are 203 and 121, respectively. Maternal-child health care programs are expected to reduce infant mortality in the years ahead. Finally, fertility declines have been noted in almost every country in the ESCAP region and have been most dramatic in East Asia, where 1983's total fertility rate was 40% lower than that in 1970-75. Key factors behind this decline include more aggressive government policies aimed at limiting population growth, developments in the fields of education and primary health care, and greater availability of contraception through family planning programs.
New York, United Nations, 1984. 108 p. (Population Studies, No. 85; ST/ESA/SER.A/85)The 3 parts of this report on world, regional, and international developments in the field of population, present a summary of levels, trends, and prospects in mortality, fertility, nuptiality, international migration, population growth, age structure, and urbanization; consider some important issues in the interrelationships between economic, social, and demographic variables, with special emphasis on the problems of food supply and employment; and deal with the policies and perceptions of governments on population matters. The 1st part of the report is based primarily on data compiled by the UN Population Division. The 2nd part is based on information provided by the Food and Agriculture Organization of the UN (FAO) and the International Labor Organization (ILO), as well as that compiled by the Population Division. The final part is based on information in the policy data bank maintained by the Population Division, including responses to the UN Fourth Population Inquiry among Governments. In 1975-80 the expectation of life at birth for the world was estimated at 57.2 years for both sexes combined. The corresponding figure for the developed and developing regions was 71.9 and 54.7 years, respectively. In 1975-80 the birthrate of the world was estimated at 28.9/1000 population and the gross reproduction rate was 1.91. These figures reflect considerable decline from the levels attained 25 years earlier: a crude birthrate of 38/1000 population and a gross reproduction rate of 2.44. World population grew from 2504 million in 1950 to 4453 million in 1983. Of the additional 1949 million people, 1645 million, or 84%, accrued to the less developed countries. The impact of population growth on economic development and social progress is not well understood. The governments of some developing countries still officially welcome a rapid rate of population growth. Many other governments see cause for concern in the need for the large increases in social expenditure, particularly for health and education, that accompany a young and growing population. Planners are concerned that the rapidly growing supply of labor, compounded by a trend toward rapid urbanization, may exceed that which the job market is likely to absorb. In the developed regions the prospect of a declining, or an aging, population is also cause for apprehension. There is a dearth of knowledge as to the impact of policies for altering the consequences of these trends. Many policies have been tried, in both developed and developing countries, to influence population growth and distribution, but the consequences of such policies have been difficult to assess. Frequently this problem arises because their primary objectives are not demographic in character.
New York, UN, 1977. 183 p. (Population Studies No. 60)The projections in this report cover the years 1970-2000. Quinquennial projections were prepared by sex and 5-year groups for each of 155 countries, 8 major areas, and 24 regions. Projections by sex and single years of age for population between ages 5-24 are provided for every region and country. Other demographic indicators were calculated for each region including population totals for males and females, sex ratio, percentage distribution by age category, dependency ratio, median age, crude birth and death rates, general and total fertility rate, life expectancy, and gross and net reproduction rate. In 1975 the world population was estimated at 4 billion; the medium variant projection for the year 2000 is 6.25 billion. The rate of growth is estimated at 1.9% for 1970. A downward trend is expected for 1985 when growth will slow to 1.6%. There will continue to be wide disparities in the rates of growth of developed and less developed nations. In the less developed regions the annual rate of growth is expected to maintain its current 2.3-2.4% for about 15 years, 1970-85, reaching 1.9%, after a downward trend, by 2000. The more developed regions should decline from .9% to .6%. The highest average annual rate of growth is in Latin America, 2.7%, (1970-5). In 1975 Africa had the highest annual rate of growth, expected to exceed 2.9% from 1985-2000. Only Eastern Africa and Middle America are expected to exceed 3% up to 1990-95.
In: United Nations. Dept. of Economic and Social Affairs. Proceedings of the World Population Conference, Belgrade, 30 August-10 September 1965. Vol. 2. Selected papers and summaries: fertility, family planning, mortality. New York, UN, 1967. 49-53. (E/CONF.41/3)U.N. world population projections place the world population in the year 2000 at anywhere between 6000 million and 7400 million. The less developed areas of the world are growing more rapidly than the developed areas. This will mean that the developed areas, which accounted for nearly 1/3 of the world population in 1960, will only account for less than 1/4 by the end of the century. The annual rate of increase suggests that the tempo of growth may be slowing slightly. The developing areas are still growing at twice the rate of the developed areas. Tables present these population projections and various projections on age structure of future populations. The world population, especially that in the developed countries, is aging, with all the concomitant social changes which that occurrence entails. The general problem of population growth must be handled within a context of socioeconomic developmental planning for each nation.
Washington, D.C., U.S. Government Printing Office, September 1978. (International Research Document No. 6) 12pCompiling population data for Afghanistan is made difficult by the nomadic population. Estimates of their numbers range from 1-2 million people, 9-14% of the total. A 1972-73 survey of the settled population accumulated data from approximately 21,000 households and 120,000 individuals. Pregnancy and marital histories were acquired from 10,000 women. The age-specific fertility rate was 8 per woman; crude birth rate, 43/1000. Estimated life expectancy for males was 34-42 years, for females, 36-41 years. The crude death rate is 28-32/1000. Of the 10,020,099 total settled population, 5,373,249 were male, 4,646,850 were female. The Afghan Family Guidance Association opened the first family planning clinic in 1968. By 1972 there were 18 clinics in operation. When surveyed, 3% of women over 15 knew about family planning, only 1/3 of these had used a family planning method. 66% males and 90% females over 15 were ever-married. About 11% of those over 6 years were literate, 18.7% males, 2.8% females.
Teheran, Iran, Population and Manpower Bureau, Planning Division, November 1973. 75 p. (Unpublished)The structure and characteristics of Iran's current population are analyzed, and an attempt is made to review and analyze Iran's population evolution and determine its future trends in the light of the research studies conducted by various organizations. Until the second half of the nineteenth century there was no population census in Iran. The period after 1946 was marked by an increase in the annual population growth rate. The size and structure of the population bears a direct relationship to changes in the economic and social conditions. The population strategy of Iran is designed so as to slow down the rate of population growth by reducing the birthrate. This study demonstrated that it cannot be expected that the population growth rate will decrease to 2% annually in the next 20 years. The death rate will decrease to .8% and the birthrate will decrease to 3-3.4%. The article provides tables on the size of population, living conditions, population changes, and urbanization trends based on the projections of this study.
In: United Nations. Economic and Social Commission for Asia and the Pacific [ESCAP]. Modelling economic and demographic development. New York, United Nations, 1983. 117-223. (Asian Population Studies Series No. 54)This study uses a longterm demographic-economic model to analyze the effects of the rapid aging of the Japanese population on various aspects of the economy and government programs. It is assumed that the quantitative analysis of the interrelationships between age-structural changes and the socioeconomic system provides a useful basis for Japanese government planners to formulate policy measures to cope with problems arising in connection with an aging population. The study draws on population, economic, and social security submodels in a series of simulation experiments. In the Standard Case, the total fertility rate falls due to economic progress and the rising age at 1st marriage, mortality improves as a result of increased per capita medical expenditures, and population grows at a diminishing rate after peaking at 131.3 million in 2007. The model further projects an increase in the percentage of the population age 65 years and over from 9.1% in 1980 to 23.9% in 2021 and a corresponding decrease in the population ages 15-64 years from 67.4% to 61.8%, Per capita real GNP is projected to continue to rise in the 1980-2025 period. However, the decreasing growth rate of the labor force, increasing financial resources for social security programs, and decline in the average hours worked by those in the labor force are expected to produce an economic slow-down, particularly in the early part of the 21st century. 5 policy measures are proposed to cope with this lowered rate of economic growth: 1) acceleration of the speed of technological progress to compensate for the shortage of young workers; 2) extension of retirement age to ease financial pressures on public pension schemes and retain the economic contributions of aged workers; 3) updating of the skills of aged workers through government vocational retraining programs; 4) the modification of public pension schemes to make benefit provision more selective, and adjustment of the amount of benefits paid out by extending the pensionable age for each scheme; and 5) review of the effectiveness and efficiency of various public medical plans, with attention to unnecessary use of medical services and improvement of preventive interventions.
