Beyond Six Billion


Book Description

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.




World Population Prospects


Book Description

Annotation. This volume presents the comprehensive tables of world population estimates and projections. Covering the 1950-2050 time period, demographic profiles and selected demographic indicators are provided for each development group, major area, region and country. The tables are accompanied by a summary of the result and the underlying assumptions. While the population at the global level continues to increase, that of the developed world is hardly changing at all and virtually all population growth is occurring in the less developed regions. Especially rapid population growth characterizes the group of 50 least developed countries. Below-replacement fertility prevails in the developed world, and mortality rates are low. In the developing world, however, fertility is still high, and mortality is increasing in countries highly affected by HIV/AIDS.

The Future of the Public's Health in the 21st Century


Book Description

The anthrax incidents following the 9/11 terrorist attacks put the spotlight on the nation's public health agencies, placing it under an unprecedented scrutiny that added new dimensions to the complex issues considered in this report. The Future of the Public's Health in the 21st Century reaffirms the vision of Healthy People 2010, and outlines a systems approach to assuring the nation's health in practice, research, and policy. This approach focuses on joining the unique resources and perspectives of diverse sectors and entities and challenges these groups to work in a concerted, strategic way to promote and protect the public's health. Focusing on diverse partnerships as the framework for public health, the book discusses: The need for a shift from an individual to a population-based approach in practice, research, policy, and community engagement. The status of the governmental public health infrastructure and what needs to be improved, including its interface with the health care delivery system. The roles nongovernment actors, such as academia, business, local communities and the media can play in creating a healthy nation. Providing an accessible analysis, this book will be important to public health policy-makers and practitioners, business and community leaders, health advocates, educators and journalists.




World Population Prospects 2019: Highlights


Book Description

The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. They are used in the calculation of many of the key development indicators commonly used by the United Nations system, including for more than one third of the indicators used to monitor progress towards the achievement of the Sustainable Development Goals. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections, which have been prepared since 1951 by the Population Division of the Department of Economic and Social Affairs. The 2019 revision presents population estimates from 1950 until the present for 235 countries or areas, which have been developed through country-specific analyses of historical demographic trends. It builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as information from vital registration and recent nationally representative household sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. These Highlights summarise key population trends described by the estimates and projections presented in World Population Prospects 2019.




Empty Planet


Book Description

From the authors of the bestselling The Big Shift, a provocative argument that the global population will soon begin to decline, dramatically reshaping the social, political, and economic landscape. For half a century, statisticians, pundits, and politicians have warned that a burgeoning planetary population will soon overwhelm the earth's resources. But a growing number of experts are sounding a different kind of alarm. Rather than growing exponentially, they argue, the global population is headed for a steep decline. Throughout history, depopulation was the product of catastrophe: ice ages, plagues, the collapse of civilizations. This time, however, we're thinning ourselves deliberately, by choosing to have fewer babies than we need to replace ourselves. In much of the developed and developing world, that decline is already underway, as urbanization, women's empowerment, and waning religiosity lead to smaller and smaller families. In Empty Planet, Ibbitson and Bricker travel from South Florida to Sao Paulo, Seoul to Nairobi, Brussels to Delhi to Beijing, drawing on a wealth of research and firsthand reporting to illustrate the dramatic consequences of this population decline--and to show us why the rest of the developing world will soon join in. They find that a smaller global population will bring with it a number of benefits: fewer workers will command higher wages; good jobs will prompt innovation; the environment will improve; the risk of famine will wane; and falling birthrates in the developing world will bring greater affluence and autonomy for women. But enormous disruption lies ahead, too. We can already see the effects in Europe and parts of Asia, as aging populations and worker shortages weaken the economy and impose crippling demands on healthcare and social security. The United States is well-positioned to successfully navigate these coming demographic shifts--that is, unless growing isolationism and anti-immigrant backlash lead us to close ourselves off just as openness becomes more critical to our survival than ever before. Rigorously researched and deeply compelling, Empty Planet offers a vision of a future that we can no longer prevent--but one that we can shape, if we choose.




The Demographic Dividend


Book Description

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.




World Urbanization Prospects


Book Description

The report presents findings from the 2018 revision of World Urbanization Prospects, which contains the latest estimates of the urban and rural populations or areas from 1950 to 2018 and projections to 2050, as well as estimates of population size from 1950 to 2018 and projections to 2030 for all urban agglomerations with 300,000 inhabitants or more in 2018. The world urban population is at an all-time high, and the share of urban dwellers, is projected to represent two thirds of the global population in 2050. Continued urbanization will bring new opportunities and challenges for sustainable development.




World Population Prospects


Book Description

This report presents the 2010 Revision of the population estimates and projections prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. The 2010 Revision constitutes the twenty second round of the global population estimates and projections produced by the Population Division since 1951 and it breaks new ground in the production of population projections. For the first time, projections are carried out up to 2100, instead of 2050 as previously. In order to extend the projection period to 2100, a new method for the projection of fertility was developed. The method used in the 2010 Revision is based on the advances made in projecting fertility since the 2000 Revision, advances that have been combined with a probabilistic approach to yield the future paths of fertility used in producing the medium variant of the 2010 Revision. The full results of the 2010 Revision are presented in two volumes. The first volume provides comprehensive tables displaying key demographic indicators for each development group, major area, region and country for selected periods or dates within 1950-2100. The second volume contains demographic profiles presenting time series and plots covering the period from 1950 to 2100 for selected indicators for each country with at least 100,000 inhabitants in 2010 as well as for development groups, major areas and regions.




Population and Land Use in Developing Countries


Book Description

This valuable book summarizes recent research by experts from both the natural and social sciences on the effects of population growth on land use. It is a useful introduction to a field in which little quantitative research has been conducted and in which there is a great deal of public controversy. The book includes case studies of African, Asian, and Latin American countries that demonstrate the varied effects of population growth on land use. Several general chapters address the following timely questions: What is meant by land use change? Why are ecological research and population studies so different? What are the implications for sustainable growth in agricultural production? Although much work remains to be done in quantifying the causal connections between demographic and land use changes, this book provides important insights into those connections, and it should stimulate more work in this area.
