Step 1. Review

Review population trends with Coloradans On the Move, an interactive demonstration of population movement in the state over three time periods.
- Demographic Summary 2022, Colorado State Demography Office, February 13, 2022
- Pre-assessment for Colorado (for use in classrooms)
- General questions about redistricting
Step 2. Discuss

Discuss how to prioritize redistricting criteria using Flashes of Insight cards or an online game.

- More States Move to Nonpartisan Redistricting to Limit Gerrymandering, Jessika Shipley, Colorado Legislative Council Staff, Here and Now, March 13, 2020
- Electoral Redistricting 101: A panel discussion about redistricting in the state of Colorado and the city of Colorado Springs
- Sponsored by the College of Letters, Arts & Sciences and the Center for the Study of Government and the Individual at the University of Colorado Colorado Springs
Step 3. Describe

Describe and map your community with online tools from Representable.org to understand what issues are important in your neighborhood and region.
Use both written and geographic descriptions to explain your community.
Step 4. Practice

Practice using geospatial technology tools in preparation for drawing sample electoral district lines with accessible, step-by-step instructions.
- What Is a Gerrymander? Esri GeoInquiries for Government
- Colorado ArcGIS Online Redistricting Exercise (2010 census data)
Step 5. Draw

Draw electoral districts with 2020 Census data using open-source geospatial technology tools.
- Explore Districtr and District Builder.
- Examine the "Notable Maps" detailed in Dave's Redistricting App to investigate different approaches to drawing electoral district lines.
- Check here to see approaches to drawing the Colorado Congressional District map.
- Review this sample explanation for an approach to submitting your own map (prepared for the El Paso County Commission).
Step 6. Analyze

Analyze redistricting maps, including any maps you created, the existing approved state maps, and various proposed maps in Dave's Redistricting App.
- Read Colorado in Context: Ensemble Analysis and Data Science for Fair Redistricting in Colorado by a group of mathematicians, statisticians, and computer scientists
- Visit maps of the Colorado House and Senate districts.
- Read In re Colo. Indep. Cong. Redistricting Comm'n, Colorado Supreme Court, November 1, 2021
- Evaluate the fairness of electoral district maps using PlanScore, from the Campaign Legal Center.
- Explore the partisan lean data from FiveThirtyEight to consider which party might benefit from a particular map.
- Investigate the Redistricting Report Card, from the Princeton Gerrymandering Project.
Step 7. Learn

Learn about issues in your community that are affected by people who represent you at the local, state, and national levels.
- Who else do you vote with? Who are your elected representatives? How did the lines change from the previous districts? How do your city, county, school board, state, and congressional districts fit together? Did your districts grow or shrink in area? How would you describe your districts (competitive, gerrymandered, representative)?
- Recall the information you identified while describing your community. What else do you need to consider when drawing districts? What watershed do you live in? What school districts serve your area? What issues are decided by state legislatures and local elected bodies that you care about?
- County and municipal jurisdictions are also important to monitor.
