This report analyzes data from the April 1984 Survey of Income and Program Participation (SIPP) on households comprised of both Aid to Families with Dependent Children (AFDC) recipients and nonrecipients. Of the 3.7 million AFDC households, 32 percent consisted of AFDC recipients and their relatives, as opposed to only recipients. Analysis of the recipients' relationships with the nonrecipients showed two basic household structures: one consisting of two generations; the other, three generations. The following characteristics were found for two-generation households: (1) they usually consist of older AFDC mothers, 73 percent of whom were over age 25 and 32 percent of whom were over 39, who headed the households; (2) in 86 percent, an AFDC recipient was the person in whose name the dwelling was leased; (3) most of the persons not on AFDC were children of the AFDC family head, and were over 18 and thus ineligible for AFDC. The following characteristics were found for three-generation households: (1) they consist of young AFDC mothers, 53 percent of whom were under age 25 and 40 percent of whom were under 21, living with their parents; (2) in less than a fourth of these, the dwelling was in the name of an AFDC recipient; and (3) most of the non-AFDC relatives were the parents or siblings of the AFDC family head. In 80 percent of three-generation households, nonrecipients had a higher per capita income than recipients. In two-generation households the overall income of AFDC recipients and non-recipients were similar. Data are presented on 10 tables and figures. Appendices provide additional data, detail the objectives, scope, methodology, and data limitations of the report, and demonstrate sampling errors for key SIPP estimates. (BJV)
