Using This Site
  • Explore these options for spending fifteen minutes to an hour to learn about redistricting.

    Watch the GeoCivics Introduction (45 minutes) which provides an overview of "On the Move" lessons and population change, considers the redistricting process and criteria, then describes and demonstrates online mapping tools.

    Watch this one-hour video from Draw The Lines PA discussing what issues matter to you, how Americans choose their representatives, the decennial census, apportionment and redistricting, approaches to and impacts of gerrymandering, and how to make a map.

    Watch the TEDx talk, Redistricting of the people, by the people, and for the people from April 2019.

    Investigate population changes in your state over time using "On the Move" lessons for each state, available on the State Resources page.  Gather paper maps and stackable objects to represent three or four different time periods.  Using National Geographic Giant State Maps?  Watch a demonstration with the Ohio map ( at 31 mins) or in North Carolina (at 4 mins, 30 secs).

    Learn about the importance of geospatial technology and GIS to the redistricting process.  Explore the approach Thomas Hofeller took to drawing electoral districts.

    Use resources to explain concepts about governing and representation which may cause confusion.

    Visit the State Resources pages to find the State ArcGIS Online Redistricting Exercises and sites such as DistrictR to draw your own electoral district maps.

    Complete this survey to share your experience.

  • You will find state-specific resources designed to provide a foundation for discussing topics related to the decennial census, the responsibility for and execution of electoral redistricting, and the implications for choices made about how to draw district lines. National, state, and local resources are also available to explore topics related to apportionment and redistricting, including international and historical approaches to redistricting, gerrymandering, voter participation, and related litigation. Organizations in your state may be able to provide additional connections with educators and community members.

  • This is the first place to visit to begin understanding specifics of the redistricting process in a particular state.

    To demonstrate movement of the population and provide historical perspective, explore an "On the Move" lesson for your state. The lesson identifies the fifteen largest cities in each state over four time periods using census data, ending in 2020. This lesson can be used with National Geographic's Giant State Maps and cones or with tabletop paper driving maps and stackable items, such as buttons or LEGOs.

    State Resources pages provide an opportunity for students and community members to create their own electoral district maps; each state with more than one congressional district has an ArcGIS exercise allowing the construction of districts by county. The State Resources pages also feature selected organizations and contacts related to each state.

  • Visit the Teacher resource page for lesson plans. 

    A background PowerPoint presentation can be altered to suit any audience. If you are presenting to a group already familiar with apportionment and redistricting, you may want to provide a short refresher to ensure everyone begins the discussion with the same base of knowledge. If you are using the state "On the Move" and "ArcGIS Online Redistricting Exercise" materials as part of a class, you may want to prepare a more extensive review of each of the topics covered. Assessment questions are also available.

    A video of the National Geographic Giant Map of North Carolina (15 minutes) provides an example of how this map resource can be utilized in the classroom and how the "On the Move" lessons are executed. Rebecca Theobald demonstrates the activity in the instructional video National Geographic Giant Map of Ohio Comes to Sinclair (3 minutes) and in the overview (45 minutes) of the GeoCivics project.

  • The RedistrictingGeography, and Civics pages are great places to start learning about these topics. Each page houses resources, created by a multitude of organizations, that address issues surrounding civics education and good governance. Mapping applications are essential to the conversation about redistricting and can be found under Geospatial Technology in Geography.

  • Choose your specific role while navigating the GeoCivics site, taking advantage of the opportunities and resources available in a manner best suited to your own intentions and learning.

  • Email Rebecca Theobald at or call her at 719-255-5217.

Additional resources and tools

  • Students sit around the Giant Map of Illinois before the activity starts.

    In GeoCivics "On the Move" lessons, use National Geographic's Giant State Maps to build the foundation of the apportionment and redistricting process.

  • AAA driving map of North Carolina with LEGOs on it

    A small AAA paper driving map with LEGOs can also be used for the "On the Move" lesson and other interactive mapping activities.

  • US Census Apportionment Map


    Apportionment is the first step in figuring out how many people will be represented by legislators in each state.

  • A student divides his state into districts using online mapping tools.

    Make your own map to learn about apportionment and redistricting through the ArcGIS Online Redistricting Exercise for each state.

  • An example of the Pennsylvania Redistricting Exercise dividing the state into 8 districts.

    How can we arrive at a map of fairly divided districts? Investigate further through GeoCivics geospatial technology tools.
