State and Local Public Policies in the United States is an ongoing research project and data compendium. On this website you can download spreadsheets containing data on policies covering everything from taxes and government spending to abortion to campaign finance, more than 200 different policies in all, for all 50 states. We also provide information on how to use these data to construct indices of policy ideology or individual freedom. The data are now available as of December 31, 2000, December 31, 2006, December 31, 2008, and December 31, 2010 (fiscal data back to 1957), allowing researchers to begin to analyze the determinants of policy change across the states on a wide range of variables.
The “summary” spreadsheet with all policy variables mistakenly did not include the policy ideology indices (policy liberalism and policy urbanism). That has now been corrected. Go to the Data page for the updated summary_11.xls spreadsheet with policy ideology indices.
