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.

Pension reform is high on the policy agenda of many advanced and emerging market economies. In advanced economies the challenge is generally to contain future increases in public pension spending as the population ages. In emerging market economies, the challenges are often different. Where pension coverage is extensive, the issues are similar to those in advanced economies. Where pension coverage is low, the key challenge will be to expand coverage in a fiscally sustainable manner. This volume examines the outlook for public pension spending over the coming decades and the options for reform in 52 advanced and emerging market economies.

Covers trends since 1954 and provides projections to 2090.

The U.S. population is aging. Social Security projections suggest that between 2013 and 2050, the population aged 65 and over will almost double, from 45 million to 86 million. One key driver of population aging is ongoing increases in life expectancy. Average U.S. life expectancy was 67 years for males and 73 years for females five decades ago; the averages are now 76 and 81, respectively. It has long been the case that better-educated, higher-income people enjoy longer life expectancies than less-educated, lower-income people. The causes include early life conditions, behavioral factors (such as nutrition, exercise, and smoking behaviors), stress, and access to health care services, all of which can vary across education and income. Our major entitlement programs - Medicare, Medicaid, Social Security, and Supplemental Security Income - have come to deliver disproportionately larger lifetime benefits to higher-income people because, on average, they are increasingly collecting those benefits over more years than others. This report studies the impact the growing gap in life expectancy has on the present value of lifetime benefits that people with higher or lower earnings will receive from major entitlement programs. The analysis presented in The Growing Gap in Life Expectancy by Income goes beyond an examination of the existing literature by providing the first comprehensive estimates of how lifetime benefits are affected by the changing distribution of life expectancy. The report also explores, from a lifetime benefit perspective, how the growing gap in longevity affects traditional policy analyses of reforms to the nation's leading entitlement programs. This in-depth analysis of the economic impacts of the longevity gap will inform debate and assist decision makers, economists, and researchers.

The past decade has brought an increasing recognition to the importance of pension systems to the economic stability of nations and the security of their aging populations. This report attempts to explain current policy thinking and update the World Bank's perspective on pension reform. This book incorporates lessons learned from recent Bank experiences and research that have significantly increased knowledge and insight regarding how best to proceed in the future. The book has a comprehensive introduction and two main parts. Part I presents the conceptual underpinnings for the Bank's thinking on pension systems and reforms, including structure of Bank lending in this area. Part II highlights key design and implementation issues where it signals areas of confidence and areas for further research and experience, and includes a section on regional reform experiences, including Latin American and Europe and Central Asia.

Greater longevity is an indicator of human progress in general. Increased life expectancy and lower fertility rates are changing the population structure worldwide in a major way: the proportion of older persons is rapidly increasing, a process known as population ageing. The process is inevitable and is already advanced in developed countries and progressing quite rapidly in developing ones. The 2007 Survey analyses the implications of population ageing for social and economic development around the world, while recognising that it offers both challenges and opportunities. Among the most pressing issues is that arising from the prospect of a smaller labour force having to support an increasingly larger older population. Paralleling increased longevity are the changes in intergenerational relationships that may affect the provision of care and income security for older persons, particularly in developing countries where family transfers play a major role. At the same time, it is also necessary for societies to fully recognise and better harness the productive and social contributions that older persons can make but are in many instances prevented from making. The Survey argues that the challenges are not insurmountable, but that societies everywhere need to put in place the policies required to confront those challenges effectively and to ensure an adequate standard of living for each of their members, while respecting and promoting the contribution and participation of all.

There is long-standing debate on how population growth affects national economies. A new report from Population Matters examines the history of this debate and synthesizes current research on the topic. The authors, led by Harvard economist David Bloom, conclude that population age structure, more than size or growth per se, affects economic development, and that reducing high fertility can create opportunities for economic growth if the right kinds of educational, health, and labor-market policies are in place. The report also examines specific regions of the world and how their differing policy environments have affected the relationship between population change and economic development.
