The Welfare Rules Databook provides tables containing key Temporary Assistance for Needy Families (TANF) policies for each state as of July 2014, as well as longitudinal tables describing selected state policies from 1996 through 2014. 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 summarizes 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 http://anfdata.urban.org/wrd.
