This report updates and expands two earlier editions which describe Federal programs which affect children and their families. An introductory section discusses and presents tables of data concerning target groups and participation in the programs; program administration; and program funding. The bulk of the report consists of profiles of approximately 125 Federal programs, including: (1) programs that provide income to children and their families, such as pensions and tax benefits; (2) nutrition programs, including food stamps and school food programs; (3) social service programs aimed at a variety of problems and groups of children; (4) education and training programs for children and youth from preschool through secondary education; (5) health programs; and (6) housing programs for low and moderate income families. Each profile describes the program's function and operation; discusses the program's authorization, and the nature and amount of its funding; and presents data on participation in the program. Appendixes include an analysis of funding trends and inflation; Government Accounting Office reports and evaluations on issues affecting children; and the views of the minority Republican members of the Committee concerning the content of the report.
