Available in PDF, EPUB and Kindle. Book excerpt: World Population: Past, Present, & Future uses a multidisciplinary approach to investigate in depth on important aspects of the evolution of world population not well addressed previously. The authors from the Universidad Autonoma, Madrid (Spain), professors Julio A Gonzalo, Manuel Alfonseca, and Félix-Fernando Muñoz, point out that the recent pronounced growth in world population (accompanied by an even more pronounced growth in agricultural production) was due mainly to the increase of life expectancy and not to the (inexistent) growth in fertility rate. Using a 'rate equations' approach for the first time, they describe population trends and forecast the possibility of steps up (or down) in population rather than the exponential growth predicted by UN demographers around 1985 and thereafter. This book provides a new perspective that our planet is not overpopulated and could, in fact, house a considerably larger population.

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.

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.

Download or read book Global Population written by Alison Bashford and published by Columbia University Press. This book was released on 2014-02-11 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about the size of the world’s population did not begin with the Baby Boomers. Overpopulation as a conceptual problem originated after World War I and was understood as an issue with far-reaching ecological, agricultural, economic, and geopolitical consequences. This study traces the idea of a world population problem as it developed from the 1920s through the 1950s, long before the late-1960s notion of a postwar “population bomb.” Drawing on international conference transcripts, the volume reconstructs the twentieth-century discourse on population as an international issue concerned with migration, colonial expansion, sovereignty, and globalization. It connects the genealogy of population discourse to the rise of economically and demographically defined global regions, the characterization of “civilizations” with different standards of living, global attitudes toward “development,” and first- and third-world designations.

Download or read book Aging and the Macroeconomy written by National Research Council and published by National Academies Press. This book was released on 2013-01-10 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States is in the midst of a major demographic shift. In the coming decades, people aged 65 and over will make up an increasingly large percentage of the population: The ratio of people aged 65+ to people aged 20-64 will rise by 80%. This shift is happening for two reasons: people are living longer, and many couples are choosing to have fewer children and to have those children somewhat later in life. The resulting demographic shift will present the nation with economic challenges, both to absorb the costs and to leverage the benefits of an aging population. Aging and the Macroeconomy: Long-Term Implications of an Older Population presents the fundamental factors driving the aging of the U.S. population, as well as its societal implications and likely long-term macroeconomic effects in a global context. The report finds that, while population aging does not pose an insurmountable challenge to the nation, it is imperative that sensible policies are implemented soon to allow companies and households to respond. It offers four practical approaches for preparing resources to support the future consumption of households and for adapting to the new economic landscape.

Global Population and International Migration offers a perspective on the causes and effects of rapid population change, and asks two vital questions: how can Earth sustain this growth? And what can we do to improve the living conditions of present and future generations?
Download or read book Population and Development written by Tim Dyson and published by Zed Books Ltd.. This book was released on 2013-07-04 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demographic transition and its related effects of population growth, fertility decline and ageing populations are fraught with controversy. When discussed in relation to the global south and the modern project of development, the questions and answers become more problematic. Population and Development offers an expert guide on the demographic transition, from its origins in Enlightenment Europe through to the rest of the world. Tim Dyson examines how, while the phenomenon continues to cause unsustainable population growth with serious economic and environmental implications, its processes have underlain previous periods of sustained economic growth, helped to liberate women from the domestic domain, and contributed greatly to the rise of modern democracy. This accessible yet scholarly analysis will enable any student or expert in development studies to understand complex and vital demographic theory.
