New Dataset: State Legislative Elections, 1971-2016

September 26th, 2017, 12:00pm by brian

I’m pleased to say that the Princeton Gerrymandering Project has just published a new dataset of state legislative elections from 1972 to 2016. This database covers over 500 election/state/year combinations, and contains over 80,000 elections. The election results can be downloaded here, and the code can be viewed on github. The dataset is based on Carl Klarner’s candidate-level state legislative data, cleaned to remove multi-member elections and other issues, as well as Ballotpedia’s 2013 – 2016 election results.

For us, it’s a resource to analyze redistricting and gerrymandering. For you, it’s whatever you want to use it for. If you need technical assistance, please write to

We’ll eventually combine these with information about the district maps under which each election was held. Stay tuned!
