Research has shown that many older adults want to age in their homes and communities, and their ability to do so often depends on the availability of home and community-based services and other supports. Five federal agencies fund these services: The Admin. on Aging (AoA) and Centers for Medicare & Medicaid Services (CMS) in the Dept. of Health and Human Services (HHS); and the Depts. of Housing and Urban Development (HUD), Transportation (DOT), and Agriculture (USDA). This report addresses: (1) federal programs that fund these services and supports for older adults; (2) how these services and supports are planned and delivered in selected localities; and (3) agencies' efforts to promote a coordinated federal system of these services and supports. Includes recommendations. Tables and figures. This is a print on demand report.
