Built on top of the legacy OpenStates data for all 50 states from ~2009-2018, this contains over one million observations of state legislation to measure how far it progressed in the bicameral legislative process. It includes an original coding scheme.
This uses a dictionary method (keyword searches of LexisNexis State Capital Universe) to identify state legislation by 22 policy areas dating back to 1991. It demonstrates high precision (placing bills into the correct category), and consistent recall over time.
This uses an automated method to estimate the policy sector of the interest groups in the National Institute for Money in State Politics database of groups registered to lobby in the 50 states from 2006-2018.
