This report classifies the wide variety of TANF and supportive services policies across states in a way that facilitates cross-state analysis linking welfare reform policies to outcomes. Specifically, the study: (1) developes typologies of state welfare (and related) policies around six key outcomes; (2) developes a public-use database with measures of 80 welfare policy variables, state economic and demographic variables, and the key outcome variables that they are hypothesized to affect; (3) uses factor analysis to create policy summary variables; and (4) uses cluster analysis to provide preliminary answers to questions about the relationships between state policy choices.
