Aging and the Macroeconomy


Book Description

The United States is in the midst of a major demographic shift. In the coming decades, people aged 65 and over will make up an increasingly large percentage of the population: The ratio of people aged 65+ to people aged 20-64 will rise by 80%. This shift is happening for two reasons: people are living longer, and many couples are choosing to have fewer children and to have those children somewhat later in life. The resulting demographic shift will present the nation with economic challenges, both to absorb the costs and to leverage the benefits of an aging population. Aging and the Macroeconomy: Long-Term Implications of an Older Population presents the fundamental factors driving the aging of the U.S. population, as well as its societal implications and likely long-term macroeconomic effects in a global context. The report finds that, while population aging does not pose an insurmountable challenge to the nation, it is imperative that sensible policies are implemented soon to allow companies and households to respond. It offers four practical approaches for preparing resources to support the future consumption of households and for adapting to the new economic landscape.

Using Science to Improve the BLM Wild Horse and Burro Program


Book Description

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.




World Population Prospects


Book Description

Annotation. This volume presents the comprehensive tables of world population estimates and projections. Covering the 1950-2050 time period, demographic profiles and selected demographic indicators are provided for each development group, major area, region and country. The tables are accompanied by a summary of the result and the underlying assumptions. While the population at the global level continues to increase, that of the developed world is hardly changing at all and virtually all population growth is occurring in the less developed regions. Especially rapid population growth characterizes the group of 50 least developed countries. Below-replacement fertility prevails in the developed world, and mortality rates are low. In the developing world, however, fertility is still high, and mortality is increasing in countries highly affected by HIV/AIDS.







Beyond Six Billion


Book Description

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.




Subnational Population Estimates


Book Description

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.




American Jewish Year Book 2019


Book Description

Part I of each volume will feature 5-7 major review chapters, including 2-3 long chapters reviewing topics of major concern to the American Jewish community written by top experts on each topic, review chapters on "National Affairs" and "Jewish Communal Affairs" and articles on the Jewish population of the United States and the World Jewish Population. Future major review chapters will include such topics as Jewish Education in America, American Jewish Philanthropy, Israel/Diaspora Relations, American Jewish Demography, American Jewish History, LGBT Issues in American Jewry, American Jews and National Elections, Orthodox Judaism in the US, Conservative Judaism in the US, Reform Judaism in the US, Jewish Involvement in the Labor Movement, Perspectives in American Jewish Sociology, Recent Trends in American Judaism, Impact of Feminism on American Jewish Life, American Jewish Museums, Anti-Semitism in America, and Inter-Religious Dialogue in America. Part II-V of each volume will continue the tradition of listing Jewish Federations, national Jewish organizations, Jewish periodicals, and obituaries. But to this list are added lists of Jewish Community Centers, Jewish Camps, Jewish Museums, Holocaust Museums, and Jewish honorees (both those honored through awards by Jewish organizations and by receiving honors, such as Presidential Medals of Freedom and Academy Awards, from the secular world). We expand the Year Book tradition of bringing academic research to the Jewish communal world by adding lists of academic journals, articles in academic journals on Jewish topics, Jewish websites, and books on American and Canadian Jews. Finally, we add a list of major events in the North American Jewish Community.




Demographic Dividends: Emerging Challenges and Policy Implications


Book Description

This book examines potential economic opportunities that countries can experience when fertility rates fall and the average life expectancy of the working age population increases. It presents detailed demographic and economic analysis of middle-income countries throughout the world in order to show how these countries can take advantage of this demographic bonus. The book first traces the common link between policies that contribute to fertility transition as well as create the right kind of environment for reaping the benefit of demographic dividend. Next, it explores different countries and regions who are at different levels of development. It assesses the long term impact of gender equality on economic growth and development in Latin America; describes the life-cycle saving patterns of Mexican households; and examines demographic determinants of economic growth in BRICS. The book also offers demographic and economic analysis of the Mediterranean area, Sub-Saharan Africa, and New Zealand. The comparison between the different territorial contexts allow for the identification of three typologies of demographic dividend: the first dividend, when the working population grows faster than total population, the second dividend, as active generations get older and invest their savings in the production system of their country, and the third dividend, based on the coexistence of two populations age structure strongly contrasting. Overall, this book argues for the need to capitalize on the opportunities that come from the demographic dividend by investing heavily in education programs, training programs for the population working age, health programs, the creation of health insurance systems as well as programs to reduce or increase fertility levels.
