Training

We provide trainings on how to get involved in using the data that the Redistricting Data Hub hosts, how to participate and access resources, and we provide demonstrations on mapping tools that use our data to draw Community of Interest and District maps.

Prison Gerrymandering

Part 1

The first of this two-part training 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.

Part 2

The second of this two-part training 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. This training is well suited for individuals and groups interested in the technical details and data issues of remedying prison gerrymandering.

Communities of Interest COI

This playlist includes an introduction to COIs as well as a three-part series that prepares users to analyze whether a proposed or enacted plan considers COIs, importing a district plan and Community of Interest map into DistrictBuilder and DRA 2020 and the process of importing a district plan and one or more community of interest maps into QGIS and Python.

What is a Community of Interest COI?

How to answer questions about your community

Learn about the kind of data that are used and how you can find insights about your communities of interests using them. This training includes a demonstration on how to use the data that is available for download for free with the Redistricting Data Hub.

Part 1: Preparing to Analyze Communities of Interest Maps

The first training of this three-part series prepares users to analyze whether a proposed or enacted plan considers Communities of Interest COI. We show you where to find and download COIs and enacted plans and explain the geographies and file types encountered when working with these maps.

Part 2: Using DistrictBuilder and DRA 2020 to Analyze a Community of Interest with Respect to Proposed Maps

The training walks you through the process of importing a district plan and Community of Interest map into DistrictBuilder and DRA 2020. We provide guidance to prevent common issues or mistakes and review the metrics and analysis capabilities unique to each tool.

Part 3: Using QGIS and Python to Analyze One or More Communities of Interest with Respect to Proposed Maps

The training walks you through the process of importing a district plan and one or more community of interest maps into QGIS and Python. We are pleased to have John Holden, creator of the QGIS Redistricting Plugin, present the QGIS demonstration and answer your questions. In the remainder of the training, we will introduce our publicly available script file that makes it easy to analyze multiple COIs and generate heat maps and metrics of interest. Watch Video

Racially Polarized Voting

Legally Significant Cases

This first training 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 Lawyers Committee to offer three trainings with background information about Racially Polarized Voting and legally significant cases.

Fred McBride is the Redistricting and Voting Rights Policy Specialist at the Lawyers Committee and has been active in voting rights for nearly 20 years. He is an expert in drawing and evaluating redistricting plans and performing racially polarized voting analysis.

Data and Elections

This training 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.

From Data to Analysis

This training 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.

Redistricting Data

Data Introduction

This data introduction session is for folks who are interested in learning more about data and how it can be accessed on the Redistricting Data Hub website. This training covers the basics of data file types, as well as the different types of data we offer and how they might be used. View Slides

How to Answer Questions About Your Community

This training is about the data hosted on the Redistricting Data Hub website how it can be applied. This training covers the basics of data analysis, and how individuals can use these skills to gain insights about their communities. View Slides

Redistricting Process

How to Prepare for Redistricting

How can you prepare for redistricting? At the Redistricting Data Hub, we recognize that a challenge in participating is having access to the necessary knowledge. This session highlights some resources we have that can assist with finding the right mapping tool for you and ways you can access the resources you need. View Slides

General Overview

This training covers the mission and goals of the RDH, as well as how our resources can be used at different points within the redistricting process. View Slides

Mapping Tool Demonstrations

DistrictBuilder

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.

How to draw Community of Interest and District Maps

This training covers how to use DistrictBuilder to draw Community of Interest and District maps.

Analyze Proposed Maps with DistrictBuilder

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.

Dave’s Redistricting App

Dave’s Redistricting aims to empower civic organizations and citizen activists to advocate for fair congressional and legislative districts, while also advocating for increased transparency in the redistricting process.

How to draw Community of Interest and District Maps

This training covers how to use Dave’s Redistricting App to draw District and Community of Interest maps.

Analyzing Proposed Maps with DRA (Dave’s Redistricting App)

Learn how to analyze proposed or final redistricting maps with DRA and understand their analytical tools. We discuss how to use DRA to measure competitiveness, compactness, proportionality, minority representation, and splitting.

QGIS Redistricting PlugIn | Draw district or district plans for the Redistricting Cycle

This training 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. Users must supply their own data, but this means that districts can be drawn at any level, including census blocks and precincts.

Representable | Draw Community of Interest maps

This training 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.
