GEO Metric Analysis of Selected Districting Plans
We are currently working our way through each state's Cogressional and legislative maps. We plan to keep this page updated as we complete our analysis.
We retrieved most of our data from Dave's Redistricting App, All About Redistricting, and the Redistricting Data Hub. We are grateful to those who maintain these sites for making the data available, as well as to those who provided data to them, including the Voting and Election Science Team, the Metric Geometry and Gerrymandering Group, and the Cook Partisan Voter Index, among others.
Each page below contains links to the specific sources used in analyzing that districting plan.
