The Princeton Gerrymandering Project does nonpartisan analysis to understand and eliminate partisan gerrymandering at a state-by-state level. The Supreme Court acknowledged the validity of our math (see our great explainer video).

Looking ahead, the strongest route to reform is at a state-by-state level—a federalist approach. Our interdisciplinary team aims to give activists and legislators the tools they need to detect offenses and craft bulletproof, bipartisan reform. Now, to demonstrate gerrymandering effects at a district-by-district level, we are collecting detailed granular data on voting and shapes of precincts and implementing methods for using the data effectively. Using geospatial analysis we are drawing demonstrative maps to help state and local reformers identify extreme gerrymanders and neutral alternatives.

In the next few years, the Princeton Gerrymandering Project has the following goals:

  • State Reports: We will prepare reports that include demonstration maps, as well as statistical and legal analyses to help good-government groups craft lasting reform strategies.
  • Improved Communication: We will show statisticians how to advance reform, activists how to write foolproof laws, and lawyers how to create arguments backed by mathematical rigor.
  • PGP OpenPrecincts: Currently, there is no central repository of precinct-level geographic data from across the country available to the public. This data has to be collected from thousands of counties nationwide. We will provide this data to the public, through a combination of our own data-gathering and data-cleaning efforts, as well as coordinating the activities of civic technologists nationwide. The information will be provided to the public through portals that will allow them to use the data to evaluate plans and to draw their own maps.

Our analysis is published widely, and our work is used by legislators and reformers of all communities, without regard to partisan affiliation.
