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.

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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "This book presents a comprehensive, detailed study of population forecasting techniques for subnational areas. It includes an analysis and projection of migration as well as numerous examples of analytical and forecasting techniques based on real data for actual localities. Fictitious data and simplified examples have been avoided. While Dr. Pittenger's study covers that range of methods used in the United States over the past 50 years, methods actually used during the 1970's are stressed"--Book jacket.

This book was released on with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of the official U.S. projections of population and households in recent decades is briefly reviewed, with particular attention to projections. The introduction of the cohort-component procedure in the 1930's opened the way for separate analysis of the trend of the components of births, deaths, and net immigration in connection with making population projections. As a further development, the period-fertility method of projecting births gave way in the 1960's to the cohort-fertility method. Consideration is now being given to various methods involving parity-progression procedures. Some alternative methods and problems of measuring the accuracy of population projections are then considered. The percent "error" in the projected population growth, by components and age, and the range from high to low expressed as a percent should also be examined in addition to the percent "error" in the total population. However accuracy is measured, the projections made in the 1930's and 1940's were often wide of the mark, and those made in the 1950's and 1960's failed to anticipate the sharp changes which occurred, even though the actual figures usually fell within the range projected. Elaboration of projection methodology has not resulted in any great increase in the precision of the projections, largely because birth rates have fluctuated widely, and the fluctuations have proven difficult, if not impossible, to predict. The projections of households have had a roughly similar history, and the methods and problems of evaluation are somewhat similar. Their development has been characterized by the introduction of alternative and changing "headship" rates and increasing disaggregation of the data and procedures. The paper concludes with some generalizations based on U.S. experience. Although refinement of methods may contribute little to accuracy, accuracy is only one aspect of the usefulness of projections. The need for conditional projections and their analytical usefulness are such that there is no question that we should confidently continue to make them.
