This supplement was designed to be used in conjunction with Paper No. Six, which contains a detailed description of the methodology employed. In conjunction with General Accounting Office, the Subcommittee on Fiscal Policy chose as study sites six areas of the Nation from among the 59 census areas which have been designated by the Census Bureau as low-income areas. The data in this study are based on the benefits available to the total household. The records of 100 Federal, State, and local programs were examined to determine whether any members of the households participated in them, the amount and nature of the benefits, and other social and economic characteristics of the households. This information was assembled and analyzed in the aggregate. The 100 programs searched include all cash benefit programs under Federal, State, or local sponsorship, such as public assistance, veteran's pensions and compensation, Government employee retirement and disability plans, workmen's compensation, unemployment insurance, and social security. Also examined were all programs offering subsidies in the form of food, medical, or housing benefits. Finally, service programs such as legal aid, child care, manpower training, and education assistance were included. Benefit information from these programs were collected for a 12-month period, and an average monthly benefit was computed. However, a common 12-month period could not always be applied, since the currency and structure of agency records vary across programs. (Author/JM)
