Forecasting populations, beyond fifteen years requires an encyclopedic knowledge of the national, regional, and local socioeconomic, political, and physical environments, combined with a large measure of imagination. Projections of this type are increasingly required by private and public decision-makers. The authors, who are top researchers in this area, have provided a comprehensive analysis that goes beyond the standard fifteen-year forecast. Local Population and Employment Projection Techniques presents a set of programmed models that project the populations of minor civil divisions (MCDs) up to fifty years and employment of counties up to twenty-five years. Three classes of MCD population models are presented, each of which is constrained at the county scale by county projections that are, constrained by state and national projections. The simplest model extrapolates a trend in the historical growth rates of MCDs, while a second method is based on the distributional properties of projections made by regional or county agencies. A procedure is provided for allocating the projections to an alternative set of spatial units. The second part of this book provides employment projection methods. Four models are presented: one is a simple regression model, and there are three step-down models: one of which is a constant share model; a second model weights the constant share projections by population projections; and a third includes a competitive component. In addition, each portion of the book contains three major pieces: an overview of available projection models; state, county, and, in the case of population projections, minor civil division models; computer programs, user's instructions, and the input and output of a sample problem.

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.

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 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.

In Chapter 3, the author outlines a four-step projection procedure which is used throughout the remainder of the book. Chapter 4 describes how to project population size by comparing the growth pattern of the population under study with that of another population. The next chapter covers one of the most commonly employed techniques of population projection - the cohort-survival model, which is used not only to project the size of a population but also its composition in terms of age and sex groupings. The final chapter focuses on migration, generally the most volatile component of the basic demographic equation. Primarily written for courses in planning, this book is also useful for anyone having to make decisions affected by population trends, whether they involve planning for future growth or alerting local decisionmakers to external uncertainties that could have a serious impact on the future of their community.

Population change and population forecasts are receiving considerable attention from governmental planners and policy-makers, as well as from the private sector. Old patterns of population redistribution, industrial location, labor-force participation, household formation, and fertility are changing. The resulting uncertainty has increased interest in forecasting because mere extrapolations of past trends are proving inadequate. In the United States of America popUlation forecasts received even more attention after federal agencies began distributing funds for capital infrastructure to state and local governments on the basis of projected future populations. If the national government had based those funding decisions on locally prepared projections, the optimism of local officials would have resulted in billions of dollars worth of excess capacity in sewage treatment plants alone. Cabinet-level inquiries concluded that the U. S. Department of Commerce should (1) assume the responsibility for developing a single set of projections for use whenever future population was a consideration in federal spending decisions and (2) develop methods which incorporate both economic and demographic factors causing population change. Neither the projections prepared by economists at the Bureau of Economic Analysis nor those prepared by demographers at the Bureau of the Census were considered satisfactory because neither method adequately recognized the intertwined nature of demographic and economic change. Against this background, the American Statistical Association (ASA) and the U. S.
