World Population

Drawing on the 2019 revision of World Population Prospects, the World Population Ageing 2019 (Highlights) document global and regional trends in population ageing, including consideration of the implications of these trends for the implementation of the 2030 Agenda. The report also presents various concepts and indicators related to population ageing and discusses related fiscal and economic implications.

Condensed into a detailed analysis and a selection of continent-wide datasets, this revised edition of World Population & Human Capital in the Twenty-First Century addresses the role of educational attainment in global population trends and models. Presenting the full chapter text of the original edition alongside a concise selection of data, it summarizes past trends in fertility, mortality, migration, and education, and examines relevant theories to identify key determining factors. Deriving from a global survey of hundreds of experts and five expert meetings on as many continents, World Population & Human Capital in the Twenty-First Century: An Overview emphasizes alternative trends in human capital, new ways of studying ageing and the quantification of alternative population, and education pathways in the context of global sustainable development. It is an ideal companion to the county specific online Wittgenstein Centre Data Explorer.

A new edition of this classic history of demography text, which has been updated to strengthen the major subject areas of Africa, international migration and population and the environment Includes the latest statistical information, including the 2015 UN population projections revision and developments in China's population policy Information is presented in a clear and simple form, with academic material presented accessibly for the undergraduate audience whilst still maintaining the interest of higher level students and scholars The text covers issues that are crucial to the future of every species by encouraging humanity's search for ways to prevent future demographic catastrophes brought about by environmental or human agency Analyses the changing patterns of world population growth, including the effects of migration, war, disease, technology and culture

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. 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. This volume of the 2019 Revision presents the demographic profiles of the official United Nations population estimates and projections. The demographic profiles display key demographic indicators for selected periods or dates between 1950-2100, for the world, development groups, regions, subregions (50 aggregates) and 201 countries or areas with more than 90,000 inhabitants in 2019. In all tables and figures, values for 1950-2020 are estimates and those thereafter are projections (medium variant, and lower and upper 95 per cent prediction intervals for figures). For each country or area, the volume also provides a brief description of the data sources and demographic methods that were used to derive the base-year estimates of population and components of demographic change (fertility, child, adult and overall mortality, international migration).

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.

This book examines the history behind the formulation, implementation, and evaluation of population policies in the more developed, the less developed, and the least developed countries from 1950 until today, as well as their future prospects. It links population policies with the theories of the demographic, epidemiological, and migratory transitions. It begins by summarizing the demographic situation around the world, with an emphasis on population policies and their underlying theories. Then, it reviews the early efforts to reduce mortality and fertility in the developing countries. This is followed by a description of the internationalization of the debate on population issues and the transformation of these programs into more formal population policies, particularly in the developing countries. The book reviews also the situation of the developed countries and their specific challenges – sub-replacement fertility, population aging, and immigration – and examines the effectiveness of population policies. It also explores the way forward and future prospects for population policies over the next decades. The book provides numerous concrete examples from all over the world, and show how population policies are actually implemented and what have been their successes as well as their constraints. Above all, the book highlights the importance of understanding underlying demographic trends when assessing the development prospects of any country. The book is recommended for not only demographers, social scientists, and policymakers but also economists and political scientists who are interested in social and demographic change around the world. Demography students and researchers who are interested in applying knowledge on population trends and prospects in designing and evaluating public policies will find this an invaluable reference work.

Demographic study and the idea of a “population” was developed and modified over the course of the twentieth century, mirroring the political, social, and cultural situations and aspirations of different societies. This growing field adapted itself to specific policy concerns and was therefore never apolitical, despite the protestations of practitioners that demography was “natural.” Demographics were transformed into public policies that shaped family planning, population growth, medical practice, and environmental conservation. While covering a variety of regions and time periods, the essays in this book share an interest in the transnational dynamics of emerging demographic discourses and practices. Together, they present a global picture of the history of demographic knowledge.
