The Welfare Rules Databook provides tables containing key Temporary Assistance for Needy Families (TANF) policies for each state and the District of Columbia, Guam, Puerto Rico, and the Virgin Islands as of July 2023, as well as longitudinal tables describing selected state policies from 1996 through 2023. The report also provides updated information on selected policies related to the COVID-19 pandemic. The tables are based on the information in the Welfare Rules Database (WRD), a publicly available, online database tracking cash assistance policies over time and across the 50 states, the District of Columbia, and territories. The Databook presents a subset of the information in the WRD. Users interested in a greater level of detail are encouraged to use the full database, available at https://wrd.urban.org. Users interested in shorter summaries may consult a Graphical Overview of State and Territory TANF Policies as of July 2023 for an overview of key TANF policy changes.
