POPULATION AND DEVELOPMENT REVIEW. 2000 Jun; 26(2):413-7.This article is a reprint of the executive summary of the UN Population Division report entitled "Replacement Migration: Is it a Solution to Declining and Ageing Population?" The UN report computed the size of replacement migration and investigated the possible effects of replacement migration on the population size and age structure for eight countries and two regions that have a common fertility pattern of below the replacement level for the period 1995-2050. Major findings revealed that, the populations of most developed countries are projected to become smaller and older as a result of below-replacement fertility and increased longevity. In the absence of migration, these declines in population size will be even greater than projected. Therefore, the challenges being brought about by the decline and aging population will require objective, thorough, and comprehensive reassessments of many established economic, social and political policies and programs, in particular the replacement migration.
In: UNFPA: 1986 report, [by] United Nations Fund for Population Activities. New York, New York, UNFPA, 1987. 6-31.The implications of population growth and prospects for the future are examined in a 1987 UNFPA report on the state of world population. Demographic patterns in developed and developing countries are compared, as well as life expectancy and mortality rates. Although most countries have passed the stage of maximum growth, Africa's growth rate continues to increase. Changes in world population size are accompanied by population distribution and agricultural productivity changes. On an individual level, the fate of Baby 5 Billion is examined based on population trajectories for a developing country (Kenya, country A), and a developed country of approximately the same size (Korea, country B). The report outlines the hazards that Baby 5 Billion would face in a developing country and explains the better opportunities available in country B. Baby 5 Billion is followed through adolescence and adulthood. Whether the attainment of 5 billion in population is a threat or a triumph is questioned. Several arguments propounding the beneficial social, economic, and environmental effects of unchecked population growth are refuted. In addition, evidence of the serious consequences of deforestation and species extinction is presented. The report concludes with an explanation of the developmental, health and economic benefits of vigorous population control policies, especially in developing countries.
People. 1981; 8(2):26.The slowed down world population growth rate masks the magnitude of the net population increase. This warning comes in the new set of population projections prepared by the United Nations Population Division in 1980. These estimates, submitted to the 21st session of the Population Commission in January, indicate that the annual rate of growth of the world population had declined from 2% about 15 years ago to 1.7% and may decline to 1.5% by the end of the century. The world population has increased by 1.9 billion in the last 3 decades; 2.6 billion people are expected to be added in the coming 3 decades, bring the world population to 7 billion by 2010. About nine-tenths of the annual increase is having to be absorbed in the developing countries, despite a substantial decline in the birth rate of 41/1000 in 1960-65 to 32/1000 at present. Most of the decline has occurred in China and in several Asian and Latin American countries. Little or no decline is yet apparent in South Asia and Africa. By 1978 only 7 out of 24 Western developed countries had fertility rates above the replacement level. The UN Population Division's analyses of government policies in 165 countries show that 84 governments consider fertility levels in their countries to be satisfactory, 22 too low and 59 too high. 17 governments have policies to increase fertility and 39 to reduce it.
