As the United States and the rest of the world face the unprecedented challenge of aging populations, this volume draws together for the first time state-of-the-art work from the emerging field of the demography of aging. The nine chapters, written by experts from a variety of disciplines, highlight data sources and research approaches, results, and proposed strategies on a topic with major policy implications for labor forces, economic well-being, health care, and the need for social and family supports.

Tommy Bengtsson Population ageing, the shift in age distribution towards older ages, is of immense global concern. It is taking place to a varying degree all over the world, more in Europe and some Asian countries, less on the African continent. The worldwide share of people aged 65 years and above is predicted to increase from 7. 5% in 2005 to 16. 1% in 2050 (UN 2007, p. 11). The corresponding ?gures for developed countries are 15. 5 and 26. 2% and for developing countries 5. 5 and 14. 6%. While population ageing has been going on for some time in the developed world, and will continue to do so, most of the change is yet to come for the developing world. The change in developing countries, however, is going to be much faster than it has been in the developed world. For example, while it took more than 100 years in France and more than 80 years in Sweden for the population group aged 65 and above to increase from 7 to 14% of the population, the same change in Japan took place over a 25-year period (UN 2007, p. 13). The scenario for the future is very similar for most developing countries, including highly populated countries like China, India and Brazil. While the start and the speed differ, the shift in age structure towards older ages is a worldwide phenomenon, stressing the signi?cance of the concept global ageing.

Almost 25 years have passed since the Demography of Aging (1994) was published by the National Research Council. Future Directions for the Demography of Aging is, in many ways, the successor to that original volume. The Division of Behavioral and Social Research at the National Institute on Aging (NIA) asked the National Academies of Sciences, Engineering, and Medicine to produce an authoritative guide to new directions in demography of aging. The papers published in this report were originally presented and discussed at a public workshop held in Washington, D.C., August 17-18, 2017. The workshop discussion made evident that major new advances had been made in the last two decades, but also that new trends and research directions have emerged that call for innovative conceptual, design, and measurement approaches. The report reviews these recent trends and also discusses future directions for research on a range of topics that are central to current research in the demography of aging. Looking back over the past two decades of demography of aging research shows remarkable advances in our understanding of the health and well-being of the older population. Equally exciting is that this report sets the stage for the next two decades of innovative researchâ€"a period of rapid growth in the older American population.

This book asks why some countries devote the lion's share of their social policy resources to the elderly, while others have a more balanced repertoire of social spending. Far from being the outcome of demands for welfare spending by powerful age-based groups in society, the 'age' of welfare is an unintended consequence of the way that social programs are set up. The way that politicians use welfare state spending to compete for votes, along either programmatic or particularistic lines, locks these early institutional choices into place. So while society is changing - aging, divorcing, moving in and out of the labor force over the life course in new ways - social policies do not evolve to catch up. The result, in occupational welfare states like Italy, the United States, and Japan, is social spending that favors the elderly and leaves working-aged adults and children largely to fend for themselves.

Aging is a process that encompasses virtually all aspects of life. Because the speed of population aging is accelerating, and because the data needed to study the aging process are complex and expensive to obtain, it is imperative that countries coordinate their research efforts to reap the most benefits from this important information. Preparing for an Aging World looks at the behavioral and socioeconomic aspects of aging, and focuses on work, retirement, and pensions; wealth and savings behavior; health and disability; intergenerational transfers; and concepts of well-being. It makes recommendations for a collection of new, cross-national data on aging populationsâ€"data that will allow nations to develop policies and programs for addressing the major shifts in population age structure now occurring. These efforts, if made internationally, would advance our understanding of the aging process around the world.
