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.
Book Synopsis State and Local Population Projections by : Stanley K. Smith
Download or read book State and Local Population Projections written by Stanley K. Smith and published by Springer Science & Business Media. This book was released on 2005-12-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial plans for this book sprang from a late-afternoon conversation in a hotel bar. All three authors were attending the 1996 meeting of the Population As- ciation of America in New Orleans. While nursing drinks and expounding on a variety of topics, we began talking about our current research projects. It so happened that all three of us had been entertaining the notion of writing a book on state and local population projections. Recognizing the enormity of the project for a single author, we quickly decided to collaborate. Had we not decided to work together, it is unlikely that this book ever would have been written. The last comprehensive treatment of state and local population projections was Don Pittenger’s excellent work Projecting State and Local Populations (1976). Many changes affecting the production of population projections have occurred since that time. Technological changes have led to vast increases in computing power, new data sources, the development of GIS, and the creation of the Internet. The procedures for applying a number of projection methods have changed considerably, and several completely new methods have been developed.
Book Synopsis A Practitioner's Guide to State and Local Population Projections by : Stanley K. Smith
Download or read book A Practitioner's Guide to State and Local Population Projections written by Stanley K. Smith and published by Springer Science & Business Media. This book was released on 2013-12-16 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the methodology and analysis of state and local population projections. It describes the most commonly used data sources and application techniques for four types of projection methods: cohort-component, trend extrapolation, structural models, and microsimulation. It covers the components of population growth, sources of data, the formation of assumptions, the development of evaluation criteria, and the determinants of forecast accuracy. It considers the strengths and weaknesses of various projection methods and pays special attention to the unique problems that characterize small-area projections. The authors provide practical guidance to demographers, planners, market analysts, and others called on to construct state and local population projections. They use many examples and illustrations and present suggestions for dealing with special populations, unique circumstances, and inadequate or unreliable data. They describe techniques for controlling one set of projections to another, for interpolating between time points, for sub-dividing age groups, and for constructing projections of population-related variables (e.g., school enrollment, households). They discuss the role of judgment and the importance of the political context in which projections are made. They emphasize the “utility” of projections, or their usefulness for decision making in a world of competing demands and limited resources. This comprehensive book will provide readers with an understanding not only of the mechanics of the most commonly used population projection methods, but also of the many complex issues affecting their construction, interpretation, evaluation, and use.

Book Synopsis Beyond Six Billion by : National Research Council
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.
Book Synopsis Population Estimation and Projection by : James Raymondo
Download or read book Population Estimation and Projection written by James Raymondo and published by Bloomsbury Publishing USA. This book was released on 1992-06-23 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Raymondo provides a step-by-step guide through the complex issues associated with the methods of producing population estimates and projections. The author's approach reflects both his formal training in the study of population and his experience as an applied demographer, where he was frequently called upon to present technical population data to a lay audience. The result is a book firmly grounded in the methods and procedures of demography, but presented in a clear, concise manner for the everyday user of population estimates and projections. This book is a key resource for anyone dealing with population data. Raymondo begins by describing the general nature and differences of population estimates and projections. The author then takes the reader through several methodological issues that provide a foundation for the basic concepts of demographic analysis related to the production of population estimates and projections. Also provided is a helpful discussion on the intricacies of U.S. Bureau of the Census geographic concepts, and a general discussion on major sources of data for the estimation and projection process.

Book Synopsis Subnational Population Estimates by : David A. Swanson
Download or read book Subnational Population Estimates written by David A. Swanson and published by Springer Science & Business Media. This book was released on 2012-05-23 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a unified and comprehensive treatment of the theory and techniques of sub-national population estimation, this much-needed publication does more than collate disparate source material. It examines hitherto unexplored methodological links between differing types of estimation from both the demographic and sample-survey traditions and is a self-contained primer that combines academic rigor with a wealth of real-world examples that are useful models for demographers. Between censuses, which are expensive, administratively complex, and thus infrequent, demographers and government officials must estimate population using either demographic modeling techniques or statistical surveys that sample a fraction of residents. These estimates play a central role in vital decisions that range from funding allocations and rate-setting to education, health and housing provision. They also provide important data to companies undertaking market research. However, mastering small-area and sub-national population estimation is complicated by scattered, incomplete and outdated academic sources—an issue this volume tackles head-on. Rapidly increasing population mobility is making inter-census estimation ever more important to strategic planners. This book will make the theory and techniques involved more accessible to anyone with an interest in developing or using population estimates.
Book Synopsis Local Area Population Research and Federal Programs by : Richard A. Engels
Download or read book Local Area Population Research and Federal Programs written by Richard A. Engels and published by . This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population estimates are observed to play a central part in both the qualification of local areas for Federal programs and in the distribution of fiscal assistance funds. General Revenue Sharing is singled out as perhaps the most familiar and well supported program relying, at least in part, upon total population as a distribution mechanism. Local research resulting in population estimates is noted to have been adopted for use in such allocation systems for selected States. The Federal-State Cooperative Program for Local Population Estimates (FSCP) has strengthened these programs through joint State-Census Bureau efforts. It is speculated that similar arrangements may be possible for other currently active legislative programs based upon population characteristics. Contact with a newly formed FSCP subcommittee, a Census Bureau estimating methods research unit, or State-local cooperative groups emerging in some States are suggested potential avenues for local research to impact as many as 103 separate pieces of legislation depending upon some item of population information for operation of the program. Similar opportunities are identified for population projections. Although no legislation contains formal provisions for the use of projections to the degree now specified for current population estimates, projections are relied upon for the administration of programs in the Environmental Protection Agency and in the Department of Transportation. Other instances of projections used in planning applications are identified, as are the likely points of entry for local research work.

Download or read book Demography written by Sarah Harper and published by Oxford University Press. This book was released on 2018-05-11 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generation into which each person is born, the demographic composition of that cohort, and its relation to those born at the same time in other places influences not only a person's life chances, but also the economic and political structures within which that life is lived; the person's access to social and natural resources (food, water, education, jobs, sexual partners); and even the length of that person's life. Demography, literally the study of people, addresses the size, distribution, composition, and density of populations, and considers the impact the drivers which mediate these will have on both individual lives and the changing structure of human populations. This Very Short Introduction considers the way in which the global population has evolved over time and space. Sarah Harper discusses the theorists, theories, and methods involved in studying population trends and movements, before looking at the emergence of new demographic sub-disciplines and addressing some of the future population challenges of the 21st century. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
Book Synopsis Population Dynamics and Projection Methods by : John Stillwell
Download or read book Population Dynamics and Projection Methods written by John Stillwell and published by Springer Science & Business Media. This book was released on 2011-02-15 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the human population growth rate of the world has been declining since peaking in the early 1960s, the populations of individual countries are changing at different rates. Population dynamics at national level are partly determined by levels of fertility and mortality, but the impact of international migration is playing an increasingly important role. Moreover, internal migration plays a major part in population change at the sub-national level. This fourth volume in the series “Understanding Population Trends and Processes” is a celebration of the work of Professor Philip Rees. It contains chapters by contributors who have collaborated with Phil Rees on research or consultancy projects or as postgraduate students. Several chapters demonstrate the technical nature of population projection modelling and simulation methods while others illustrate issues relating to data availability and estimation. This book demonstrates the application of theoretical and modelling methods and addresses key issues relating to contemporary demographic patterns and trends.
Book Synopsis Old and New Perspectives on Mortality Forecasting by : Tommy Bengtsson
Download or read book Old and New Perspectives on Mortality Forecasting written by Tommy Bengtsson and published by Springer. This book was released on 2019-03-28 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
