Since its inception in 1996, the Temporary Assistance for Needy Families (TANF) program has been subject to much study. Some of this work has involved linking TANF administrative data to other administrative data sources, either to improve program administration or to answer program and research questions. Researchers, program administrators, and policy makers considering similar linkages to address research, programmatic, and operational questions can learn from past efforts. This report describes the use of administrative data for program administration and provides a bibliography of TANF research involving linked administrative data.
