As we move toward ease of use in the R tidyverse, we have begun by adding CSV versions of all datasets and metadata to the Data page. The Excel workbooks still have some features that the CSV files lack, such as comment fields explaining codings for individual cells and automatically updating formulas.
The summary spreadsheet with all “top-level” policy variables and annual policy liberalism and civil libertarianism scores for all 50 states for 2000-2016 are now available on the Data page.
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.
