Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Beyond Six Billion written by National Research Council and published by National Academies Press. This book was released on 2000-10-11 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book will be of primary interest to researchers in the fields of climate change, demography, and economics. It will also be useful to policy-makers and NGOs dealing with issues of population dynamics and climate change, and to teachers and students in courses such as environmental studies, demography, climatology, economics, earth systems science, and international relations.

Download or read book Population Dynamics and Climate Change written by José Miguel Guzmán and published by UN. This book was released on 2009 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book broadens and deepens understanding of a wide range of population-climate change linkages. Incorporating population dynamics into research, policymaking and advocacy around climate change is critical for understanding trajectory of global greenhouse gas emissions, for developing and implementing adaptation plans and thus for global and national efforts to curtail this threat. The papers in this volume provide a substantive and methodological guide to the current state of knowledge on issues such as population growth and size and emissions; population vulnerability and adaptation linked to health, gender disparities and children; migration and urbanization; and the data and analytical needs for the next stages of policy-relevant research.

Download or read book Empty Planet written by Darrell Bricker and published by Signal. This book was released on 2019-02-05 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1986-02-01 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses nine relevant questions: Will population growth reduce the growth rate of per capita income because it reduces the per capita availability of exhaustible resources? How about for renewable resources? Will population growth aggravate degradation of the natural environment? Does more rapid growth reduce worker output and consumption? Do rapid growth and greater density lead to productivity gains through scale economies and thereby raise per capita income? Will rapid population growth reduce per capita levels of education and health? Will it increase inequality of income distribution? Is it an important source of labor problems and city population absorption? And, finally, do the economic effects of population growth justify government programs to reduce fertility that go beyond the provision of family planning services?
