The accelerated aging of the U.S. population is a poorly understood phenomenon with important implications for the future of health care financing and delivery. This project will update and expand previous Fund-supported work that provided an interdisciplinary analysis of how factors as diverse as the economy, advances in medical technology, housing, transportation, and public policies can affect our ability to meet the needs of an older society. Through close analysis of recent and previously unavailable data, project staff will produce a comprehensive report for policymakers, the media, and researchers that will inform debates concerning the federal budget, Medicare, Medicaid, Social Security, and employer-based programs. http://www.georgetown.edu
