Data Partners

We’re not alone in seeing the need to make the data necessary for nonpartisan redistricting widely available. Our Data Partners consist of several academic and other groups engaged in data collection. If you know of a major nonpartisan redistricting data collection effort—or you’re a part of one yourself—we want to know! Send us an email at with the subject line “Data Partners.”

More About Our Partners

MIT Election Data + Science Lab

MIT Election Data Science Lab (MEDSL) is committed to improving democracy in the United States by promoting the application of scientific principles to the understanding of election administration. Founded by political scientist Charles Stewart III, MEDSL serves as a nonpartisan source of research, data and analysis designed to improve the critical voting infrastructure including official mechanisms, administration, and logistics of the United States electoral system.

Metric Geometry and Gerrymandering Group (MGGG)

MGGG Redistricting Lab is a research group led by PI Moon Duchin at Tufts that grew out of the Metric Geometry and Gerrymandering Group. The MGGG Redistricting Lab pursues research in mathematics and technology to the field of redistricting, builds open-source tools like Districtr to increase public understanding of redistricting, partners with civil rights organizations to strengthen their quantitative capabilities, and formally and informally consults with stakeholders on all sides.

Open Elections

OpenElections is a free and open resource that has been supported by the Knight News Challenge since 2012. The goal of this project is to provide comprehensive and standardized access to historical election data in the United States. In the midst of a growing effort to compile election data, this is the first project working to create linked sets of election results data for federal, statewide and state legislative races.

Princeton Gerrymandering Project

The Princeton Gerrymandering Project (PGP) does nonpartisan analysis to understand and eliminate partisan gerrymandering at a state-by-state level under PI Samuel Wang. They develop and use mathematical tests that rigorously diagnose unequal opportunity and unfair outcomes in district maps. PGP communicates their findings through state reports that include maps and statistical and legal analysis to inform advocacy and good-government groups. They also curate the free database OpenPrecincts, which houses precinct and election data.

Prison Policy Initiative

The Prison Policy Initiative is a non-partisan non-profit that engages in research and advocacy highlighting the collateral consequences of incarceration. Formed in 2001, they provide state and local data on incarceration that is often inaccessible, and their infographics and analysis have sparked numerous reforms across the U.S. The Prison Policy Initiative is a leader in fighting prison-based gerrymandering.

Voting and Election Science Team

The Voting and Election Science Team (VEST) is working to collect and process precinct boundary and election data. Led by PIs Michael McDonald and Brian Amos, respectively, the group is based out of the University of Florida and Wichita State University. Their data can be found on the Harvard Dataverse. VEST contributes to OpenPrecincts and their collection efforts will help to prevent gerrymandering by making data more accessible to the public.
