Yesterday I posted the aggregate, state-level ideology and polarization data for our state legislature ideology data. That is actually based on legislator-level data. Today, we are posting and making public and free that individual level data.
We have extended the data collection through 2013, and we now have 20,198 unique state legislators in our data, or about 11% more than the previous update from May 2013.
As I mentioned yesterday, we have spent a lot of time and effort cleaning up the data; there should be far fewer noise-related issues. But please let us know if you see particular problems.
New this year is a district-by-year indicator, as these legislators do change districts over time.
