Today, one in eight Americans - 32 million people - is aged 65 or older. That proportion will rise to one in five by 2020. The number of elderly Americans is growing faster than the US population at large, with those aged 85 or older representing the most rapidly increasing segment of all. Because most of the elderly are no longer in the workforce, and because they are especially vulnerable to chronic illness, disability and social isolation, the projected explosion in their numbers has enormous ramifications for American society and public policy. This collection of essays, cosponsored by The Century Foundation/Twentieth Century Fund and the International Longevity Center, explores the wide-ranging economic and social consequences of the ageing of America. Compiled under the supervision of Pulitzer Prize-winning author and gerontologist Dr. Robert N. Butler, the volume presents essays by some of the nation's foremost experts on economics, demography, public policy, health care, and the media.
