This report summarizes presentations and discussions at the Workshop on the Social Processes Underlying Fertility Change in Developing Countries, organized by the Committee on Population of the National Research Council (NRC) in Washington, D.C., January 29-30, 1998. Fourteen papers were presented at the workshop; they represented both theoretical and empirical perspectives and shed new light on the role that diffusion processes may play in fertility transition. These papers served as the basis for the discussion that is summarized in this report.

Focuses on fertility and family transitions in selected Third World countries, exploring critical aspects of the relationship between population and development. The essays examine population processes as they unfold and develop over time, highlighting the need to go beyond economic explanations and identifying the priorities among social structura

China's one-child population policy, first initiated in 1979, has had an enormous effect on the country’s development. By reducing its fertility in the past two decades to less than two children per woman, and developing a family planning program focused heavily on sterilization and abortion, China has undergone a significant transition in status to a demographically developed country. Bringing together contributions from leading academics, this book looks at the impact of the government's strict control over planning and population growth on the family, the wider society and the country's demography. The contributors examine developments such as family planning policy and contraceptive use, biological and social determinants of fertility, patterns of family and marriage and China's future population trends. As such it will be essential reading for academics, researchers, policy makers and government officials with an interest in China’s population policy.

Is rapid world population growth actually coming to an end? As population growth and its consequences have become front-page issues, projections of slowing growth from such institutions as the United Nations and the World Bank have been called into question. Beyond Six Billion asks what such projections really say, why they say it, whether they can be trusted, and whether they can be improved. The book includes analysis of how well past U.N. and World Bank projections have panned out, what errors have occurred, and why they have happened. Focusing on fertility as one key to accurate projections, the committee examines the transition from high, constant fertility to low fertility levels and discusses whether developing countries will eventually attain the very low levels of births now observed in the industrialized world. Other keys to accurate projections, predictions of lengthening life span and of the impact of international migration on specific countries, are also explored in detail. How good are our methods of population forecasting? How can we cope with the inevitable uncertainty? What population trends can we anticipate? Beyond Six Billion illuminates not only the forces that shape population growth but also the accuracy of the methods we use to quantify these forces and the uncertainty surrounding projections. The Committee on Population was established by the National Academy of Sciences (NAS) in 1983 to bring the knowledge and methods of the population sciences to bear on major issues of science and public policy. The committee's work includes both basic studies of fertility, health and mortality, and migration; and applied studies aimed at improving programs for the public health and welfare in the United States and in developing countries. The committee also fosters communication among researchers in different disciplines and countries and policy makers in government, international agencies, and private organizations. The work of the committee is made possible by funding from several government agencies and private foundations.

There is long-standing debate on how population growth affects national economies. A new report from Population Matters examines the history of this debate and synthesizes current research on the topic. The authors, led by Harvard economist David Bloom, conclude that population age structure, more than size or growth per se, affects economic development, and that reducing high fertility can create opportunities for economic growth if the right kinds of educational, health, and labor-market policies are in place. The report also examines specific regions of the world and how their differing policy environments have affected the relationship between population change and economic development.

Fertility rates and population growth influence economic development. The marked declines in fertility seen in some developing nations have been accompanied by slowing population growth, which in turn provided a window of opportunity for rapid economic growth. For many sub-Saharan African nations, this window has not yet opened because fertility rates have not declined as rapidly there as elsewhere. Fertility rates in many sub-Saharan African countries are high: the total rate for the region is estimated to be 5.1 births per woman, and rates that had begun to decline in many countries in the region have stalled. High rates of fertility in these countries are likely to contribute to continued rapid population growth: the United Nations projects that the region's population will increase by 1.2 billion by 2050, the highest growth among the regions for which there are projections. In June 2015, the Committee on Population organized a workshop to explore fertility trends and the factors that have influenced them. The workshop committee was asked to explore history and trends related to fertility, proximate determinants and other influences, the status and impact of family planning programs, and prospects for further reducing fertility rates. This study will help donors, researchers, and policy makers better understand the factors that may explain the slow pace of fertility decline in this region, and develop methods to improve family planning in sub-Saharan Africa.
