This contributed volume provides a broad-based and in-depth exploration of demographic and related issues facing American society as it anticipates the retirement of the so-called baby boomers. The work provides a critical examination of the population and labor force projections most commonly used in discussions of retirement in the next century; looks at issues relating to the health and age structure of the population, examining those issues in the context of support mechanisms for retirement income security; and considers the potential lessons to be learned from the experiences of other industrialized societies in dealing with an aging population.
