In this training, held 10/5/23, learn how to draw maps for your city, county, school board, or other local jurisdiction. See how to access all the same great features and tools available for analyzing statewide plans. We close with some cautions around local redistricting data and criteria, and highlight the local data coming to the RDH website.
View Slides ►Learn how race and ethnicity are defined for the purposes of redistricting, and what data on race and ethnicity is available DRA. See how to check the demographics of districts while you are drawing or as part of a final map analysis. We’ll also discuss ways to visualize race or ethnicity in DRA, and considerations to keep in mind while using the tool. Training held 11/21/23.
View Slides ►In this training held on 3/28/24, we take a look at partisan fairness: what it is, a few of the more common measurements, and how to access the metrics available in DRA. We’ll also discuss how to look up the requirements in your state, and highlight important considerations for and limitations to analyzing the partisan fairness of a map.
View Slides ►In this video tutorial, we’ll show you how to import custom data in CSVs into Dave’s Redistricting App. By ensuring your data is properly formatted, you can easily import demographic data, voter turnout data, and election results to draw and analyze maps. You can also read their article that is suggested at the end of the video.
DistrictBuilder is a free, open-source mapping tool. It puts the power of drawing electoral maps in the hands of the people. Redistricting can be a transparent process that represents communities fairly and prevents gerrymandering.
This training, held 3/30/21, covers how to use DistrictBuilder to draw Community of Interest and District maps.
Learn how to analyze proposed or final redistricting maps with DistictBuilder and understand their analytical tools. These tools include measuring population deviation, contiguity, competitiveness, compactness, county splits, and Voting Rights districts. Training held 11/18/21.
This training, held 6/22/21, covers the basics of using the plugin for drawing districts or district plans for the Redistricting cycle.
The QGIS Redistricting Plugin is a free and open source desktop redistricting software developed by John Holden for drawing single districts or statewide district plans through QGIS software. It is available for download through the QGIS plugins app or this this website.
This training, held 5/3/21, covers how to use Representable to draw a community of interest map.
Representable is a free, open-source mapping tool for creating Communities of Interests (COI). This tool is built in partnership with the Princeton Gerrymandering Project (PGP) and supported by Schmidt Futures.
Most mapping tools are designed for drawing or analyzing a single map, but often people want to know how a map compares to another map. This training, held 9/14/23, will show you how to easily compare maps in two free mapping tools: Redistricting & You and Dave’s Redistricting.
View Slides ►This first training (held 11/16/21) in the series is great for folks who may not know much about the Voting Rights Act or racially polarized voting. It’s also an opportunity to learn directly from an expert active in the field.
We are partnering with Fred McBride of the Southern Poverty Law Center to offer three trainings with background information about Racially Polarized Voting and legally significant cases.
Fred McBride is Senior Advisor-Voting Rights for the Southern Poverty Law Center, and has been active in voting rights for nearly 25 years. He is an expert in drawing and evaluating redistricting plans and performing racially polarized voting analysis.
This training (held 11/30/21) covered the data sets and election results required to conduct RPV analysis, where to find these data and election results, and how RPV analysis varies in certain Circuit Court jurisdictions.
Dr. Lisa Handley has over twenty-five years of experience in the areas of redistricting and voting rights, both as a practitioner and an academician, and is recognized nationally (as well as internationally) as an expert on these subjects. She has advised numerous jurisdictions and other clients on redistricting and has served as an expert in dozens of redistricting and voting rights court cases.
This training (held 12/7/21) covers the common statistical methods used to perform RPV analysis, the difficulties that arise when interpreting RPV analysis results, and what to look for in an RPV analysis practitioner.
In this one hour deep dive into data for prison gerrymandering reform, you’ll learn about the practice of prison gerrymandering and why it matters for representation, whether your state has implemented any reforms, and what data is available to understand the impact in your state. We’ll also highlight some of the analysis and support we’ve provided to groups working on the issue. Training held 6/22/23.
View Slides ►The first of this two-part training (held 3/9/22) was hosted by Brianna Remster of Villanova University. This training covered the basics of prison gerrymandering: what it is, what the impacts are for representation and political power, and the possible policy remedies, including reallocation of incarcerated populations. This training is well suited for individuals who want to learn more about the practice and implications of prison gerrymandering.
View Slides ►The second of this two-part training (held 3/15/22) was hosted by Rory Kramer of Villanova University. This training dives into the nuts and bolts of prison gerrymandering, and how the reallocation of incarcerated populations to their last known address works in theory and in practice.
