This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

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.

Download or read book World Population Prospects 2019: Highlights written by United Nations Publications and published by . This book was released on 2019 with total page 0 pages. 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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Five innovative methods of establishing the population characteristics of small areas are introduced and evaluated in this book. Changes in communities can be slow, but recent history has seen huge growth in some areas and depopulation of others. As a result, population estimating has grown up under pressure from legislators and administrators who place a high premium on validity. The contributors to this volume provide ideas that have been tested in practice, anticipate the usual types of error, and are suitable for different purposes.

Download or read book Population Growth written by Ronald Freedman and published by Transaction Publishers. This book was released on 2008-02-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population of the modern world continues to grow at a rate unprecedented in human history. How are we to explain this massive increase in the number of living people? What is its consequence, now and for the future? How have populations changed in size and structure since the advent of industrial technology? Can we predict the population trends in developing countries? These and many other significant questions are dealt with in a persuasive yet accessible manner in Ronald Freedman's pivotal Population Growth. Modern population trends are unique in historical perspective; describing them as part of a "vital revolution" is not an exaggeration. The more popular term "population explosion" is less accurate because it refers to only one aspect of the current situation--the unprecedented growth rates. In the last two centuries other important trends have developed, also without precedent in all of the previous millennia of human history. While the size of population growth is very important in itself, the essays in this volume demonstrate that many other aspects of structure and change in populations are equally important. In readable, non-technical language, these collected essays analyze the most important modern trends in world population. The essays include comprehensive discussions of population theory, analyses of population trends, and prospects in the United States and surveys of population trends in other major areas of the world. As a survey of current population problems, this book will be a library staple for those involved in international development programs, sociologists, family planning workers, and everyone concerned with the contemporary vital revolution in population. Ronald Freedman is Research Professor Emeritus at the Population Studies Center at the University of Michigan. He is a member of the National Academy of Arts and Sciences and has studied population and reproductive behavior particularly in Asia. In addition to this book he is the author of numerous journal articles and research reports.

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.
