This report summarizes and synthesizes the programs, policies, research, and evaluations that serve or target youth. It examines the youth-serving activities and initiatives of nine federal agencies--the United States Departments of Health and Human Services; Education; Labor; Justice; Agriculture; Interior; Housing and Urban Development; Defense; and Commerce--as well as ACTION (the federal domestic volunteer agency); and the Commission on National and Community Services. The report has an introduction and chapters for each of the agencies, which include program descriptions and funding levels, agency organizational charts, and program overview charts for the longer chapters. The six appendices present the following information: (1) agencies' state funding allocations; (2) an index of federal clearinghouses and resource centers; (3) a listing of national organizations that serve youth; (4) a selected bibliography; (5) information about the funders of this report; and (6) an index.
