Our former host went down without warning and the entire statepolicyindex.com website and associated data were unavailable for some weeks. We are in the process of restoring all the information from the old website. We continue to update the data and have decided to share with other researchers the latest data. You will find some missing data in these spreadsheets, but we are endeavoring to code every single variable for every year as of December 31 (date of enactment) between 2000 and 2016. Some policies have data going back to the 1950s or even 1930s.
Statepolicyindex.com will continue to be political scientists’ go-to source for the most comprehensive data on state and local public policies over time.
