While a large body of research examines cross-state variation in social policy, few studies systematically examine the policy influence of organizations that advocate on behalf of people living in poverty. This article examines relationships between state advocacy communities and policy choices following the passage of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA), or welfare reform. Using an original data set of states’ advocacy communities, political and economic characteristics, and welfare policy choices, the article analyzes whether a state’s advocacy community is associated with its decisions to reduce the government’s commitment to low-income families on one hand and enact policies providing additional supports to families on the other. The analysis reveals that significant relationships exist for both types of policies, suggesting that organizational advocates may play a role in shaping state-level social policy decisions.
