We are committed to nonpartisanship and ending gerrymandering in all forms
The nonpartisan Redistricting Data Hub provides individuals, good government organizations, and community groups the data, resources, and knowledge to participate effectively in the redistricting process.
In service of this mission, we host over 12,000 datasets in all 50 states, from the census block to the district level, and continue to add new data that is useful for nonpartisan map drawing and analysis. This data is free to the public, and accompanied by technical support and nonpartisan analysis on request.
The Redistricting Data Hub is a project of the Fair Representation in Redistricting Initiative, a project of New Venture Fund (NVF). NVF has contracted with HaystaqDNA—a political data consulting firm with a track record of success in supporting nonpartisan redistricting—to provide the publicly-available data and services. There is a firewall between the Redistricting Data Hub work and services and any other work provided by HaystaqDNA to any of its other clients.
The Redistricting Data Hub operates as an independent and autonomous project, overseen by the Fair Representation in Redistricting advisory committee. All Redistricting Data Hub employees are fully committed to nonpartisanship and ending gerrymandering in all forms.
Over the course of the 2021 redistricting cycle, the Redistricting Data Hub was proud to serve good government, civil rights, and community groups in their fight for fair maps. Our data was used in numerous briefs and expert reports submitted during litigation, and by groups to create alternative maps and submit testimony to state and congressional redistricting bodies.
We also supported local, state, and national journalists in their coverage of redistricting by providing technical assistance and answering questions about the data. Academics used our data for publicly available research, and educators used it to teach the next generation about redistricting. And thousands of members of the public have downloaded our data to submit testimony, understand their state’s maps, and participate meaningfully in the process.
Post 2021-redistricting cycle, we remain focused on providing critical redistricting data, particularly in those states likely to engage in mid-decade redistricting or where state legislative or congressional districts are already in litigation. We continue to support groups engaged in efforts to stop gerrymandering through litigation or by reforming the process. And we provide useful analysis and reports on redistricting.
Funding for the Redistricting Data Hub comes from the Southern Poverty Law Center and the Fair Representation in Redistricting Initiative.
❝ The Fair Representation in Redistricting Initiative was developed by a set of foundations, with nonprofit leaders, to support fair and equitable redistricting. The Initiative includes: 1) support for civic organizations and coalitions in targeted states to advance community-centered redistricting; 2) research and mitigation strategies to promote the continued use of total population for drawing districts; and 3) national support services to enable fair maps across states. ❞
The Initiative is guided by a Fair Representation in Redistricting Advisory Committee composed of representatives of the following 18 initiative funders:
❝ Founded in 1971, the Southern Poverty Law Center is a catalyst for racial justice in the South and beyond, working in partnership with communities to dismantle white supremacy, strengthen intersectional movements, and advance the human rights of all people. Our issues include hate and extremism, children’s rights, immigrant justice, LGBTQ rights, economic justice, criminal justice reform, and voting rights. SPLC’s Voting Rights Practice Group works with its community partners to engage and mobilize voters, restore voting rights to returning citizens, pursue electoral policy reforms, and bring litigation to challenge unconstitutional and discriminatory voting practices.

❝ Just wanted to let you know that I have finally downloaded and used tons of the hub’s data and it is AMAZING – thank so so much for putting all the shapefiles up there, I can easily disag/ag in Maptitude and quickly use all the data for analyzing plans. You have saved me weeks of work and I hope you also saved that time for lots of others involved in trying to make redistricting more fair! ❞

❝ When we first saw RDH, we thought “this is too good to be true?” You’ve got all these data from partners and companies we usually have to pay for. For us, it’s like is this data reliable? When we see companies come out with huge data sets. From our perspective it’s been great to have an organization that we can validate against because the last thing we want to do is put out bad information. It’s going to be a great resource that we can turn to in this cycle ❞
❝ I have been trying to make sure that everyone in the redistricting ecosystem understands the fantastic service you are providing. ❞

❝ I like the idea that it’s being somewhat professionalized, as a resource we can point to, not a black box. It’s not a partisan trick or secret data, it’s publicly available and we can trust it. That’s a financial intangible but we find it valuable. ❞
We work with a lot of different groups to help us figure out what data is needed, gather it and validate it for you to use.
Civil rights organizations and good government groups have spearheaded many of the anti-gerrymandering fights over the years. We regularly consult with representatives from these organizations to make sure we’re providing all the data needed for nonpartisan redistricting.
Our Stakeholder group meets regularly to discuss the latest in redistricting data.
All About Redistricting has long been the go-to source for anyone with questions about redistricting lawsuits. If you want to know about the rules in Alabama or the latest on the Texas redistricting lawsuits progressing through the State and Federal court systems, All About Redistricting (AAR) has the answers. As you visit our state data download pages, you’ll see links directing to the corresponding AAR state page, where you can learn more about the legal side of redistricting.
Our Data Partners are engaged in collecting Precinct Boundary and Election Results data
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.
Our ADC was made up of a prestigious group of academics and redistricting data experts who provided guidance on our data collection and processing efforts during the 2021 redistricting cycle. The last meeting held by the ADC was in December 2021.
