The Correlates of State Policy Project aims to compile, disseminate, and encourage the use of data relevant to U.S. state policy research, tracking policy differences across and change over time in the 50 states. We have gathered more than nine-hundred variables from various sources and assembled them into one large, useful dataset. We hope this Project will become a “one-stop shop” for academics, policy analysts, students, and researchers looking for variables germane to the study of state policies and politics.
In keeping with the mission of IPPSR, this Project documents, updates, and distributes various datasets germane to research on pressing public policy issues. IPPSR is committed to research transparency, replication, and data reliability. These cross-state and cross-time datasets are free and publicly available for academics, policy analysts, students, policymakers, and the research community. We welcome notification of any errors, comments, and contributions of additional datasets.
About the Datasets:
The Correlates of State Policy Project includes more than nine-hundred variables, with observations across the U.S. 50 states and time (1900 – 2016). These variables represent policy outputs or political, social, or economic factors that may influence policy differences across the states. The codebook includes the variable name, a short description of the variable, the variable time frame, a longer description of the variable, and the variable source(s) and notes.
This aggregated data set is only possible because many scholars and students have spent tireless hours creating, collecting, cleaning, and making data publicly available. Thus if you use the dataset, please cite the original data sources. For example, if you use the dataset to examine the relationship between the Policy Innovativeness Score created by Boehmke & Skinner (2012) and the Policy Liberalism Score created by Caughey & Warshaw (2015), you should include the following three citations:
- Boehmke, Frederick J., and Paul Skinner. 2012. “State Policy Innovativeness Revisited.” State Politics and Policy Quarterly 12(3):303-29.
- Caughey, Devin, and Christopher Warshaw. 2015. “The Dynamics of State Policy Liberalism, 1936–2014.” American Journal of Political Science 60 (4): 899–913.
