The Welfare Rules Databook provides tables containing key Temporary Assistance for Needy Families (TANF) policies for each state as of July 2020, as well as longitudinal tables describing selected state policies from 1996 through 2020. This year’s edition of this annual publication includes 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 state cash assistance policies over time and across the 50 states and the District of Columbia. 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 Graphical Overview of State TANF Policies as of July 2020 for an overview of key TANF policy changes and State TANF Policies during the COVID-19 Pandemic for a review of COVID-19-related policies.
