This report on social services to families receiving Aid to Families with Dependent Children (AFDC) in May 1975 is Part IV of a broad study of AFDC recipient characteristics. The background of the AFDC social service program as mandated by Title XX of the Social Security Act is delineated briefly and a one-page prose summary of the statistics included in the report is provided. The bulk of the report consists of tables of data broken down by HEW region, by state and by U.S. total on such factors as whether a service plan had been developed for the families, what social services had been provided, whether family members had been receiving help for alcohol or drug abuse problems, what kind of child care arrangements were employed for children of various ages, whether screening services had been received, what the families' WIN project status was, and whether families received CETA or WIN payments. The appendices contain a glossary of terms related to the material in this report and a detailed discussion of the sample design and accuracy of the data. (JMB)
