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.

The highly acclaimed The Future Population of the World contains the most authoritative assessment available of the extent to which population is likely to grow over the next 50 to 100 years. The book provides a thorough analysis of all the components of population change and translates these factors into a series of projections for the population of the world's regions. This revised and updated version incorporates completely new scenario projections based on updating starting values and revised assumptions, plus several methodological improvements. It also contains the best currently available information on global trends in AIDS mortality and the first ever fully probabilistic world population projections. The projections, given up to 2100, add important additional features to those of the UN and the World Bank: they show the impacts of alternative assumptions for all three components (mortality and migration, as well as fertility); they explicitly take into account possible environmental limits to growth; and, for the first time, they define confidence levels for global populations. Combining methodological innovation with overviews of the most recent data and literature, this updated edition of The Future Population of the World is sure to conform its reputation as the most comprehensive and essential publication in the field.

Genre: Social Science
ISBN: 3030424723

This open access book presents new developments in the field of demographic forecasting, covering both mortality, fertility and migration. For each component emerging methods to forecast them are presented. Moreover, instruments for forecasting evaluation are provided. Bayesian models, nonparametric models, cohort approaches, elicitation of expert opinion, evaluation of probabilistic forecasts are some of the topics covered in the book. In addition, the book is accompanied by complementary material on the web allowing readers to practice with some of the ideas exposed in the book. Readers are encouraged to use this material to apply the new methods to their own data. The book is an important read for demographers, applied statisticians, as well as other social scientists interested or active in the field of population forecasting. Professional population forecasters in statistical agencies will find useful new ideas in various chapters.

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.

Genre: Social Science
ISBN: 3030050750

This open access book describes methods of mortality forecasting and discusses possible improvements. It contains a selection of previously unpublished and published papers, which together provide a state-of-the-art overview of statistical approaches as well as behavioural and biological perspectives. The different parts of the book provide discussions of current practice, probabilistic forecasting, the linearity in the increase of life expectancy, causes of death, and the role of cohort factors. The key question in the book is whether it is possible to project future mortality accurately, and if so, what is the best approach. This makes the book a valuable read to demographers, pension planners, actuaries, and all those interested and/or working in modelling and forecasting mortality.

Andrei Rogers, one of the world's leading authorities on population trends, offers a powerful technique for carrying out regional population projections. He gives a clear step-by-step analysis and demonstrations of actual projections of future populations at the regional level. The examples show how to calculate regional population growth rates, age compositions, and spatial distributions using data from several developed and less developed countries.
