Redistricting 101 from the Brennan Center

Members of Congress, state legislators, and many city council and school board members are elected from districts. At least once per decade, the district lines are redrawn, block by block.

The way that district lines are drawn puts voters together in groups — some voters are kept together in one district and others are separated into different districts. And in our system, whichever group has more votes within a district usually decides which representative wins.

The way the lines are drawn can keep a community together or split it apart, changing whether it has representatives who feel responsible for its concerns. The way the lines are drawn can impact who wins an election. Ultimately, the way the lines are drawn can change who controls the governing body, and can change which policies get passed into law.

  • Who draws the lines? In most states, the legislature has the power to draw the lines for both congressional and state redistricting. Click here to read more about your states’ laws. See sidebar for our specific state-by-state work.
  • The importance of minority representation. Many redistricting techniques, sadly, have been abused in order to dilute minority voting power. Click here to learn more about how the redistricting process affects minority communities and Section 2 and Section 5 of the Voting Rights Act.

Citizens and community organizations can influence the redistricting process, even within the status quo, to ensure better representation. The Brennan Center provides some ideas on how you can get involved:

  • Identify and map local communities. Several states explicitly require consideration of communities of interest; political pressure can effectively force other states to consider them as well. Communities of interest, however, are notoriously difficult to identify concretely. You can assist advocates, legislators, and others responsible for drawing district lines by mapping boundaries of local communities that should be kept together within a district — or if a sizable community prefers to be split in order to influence a larger number of representatives, drawing lines that show where the most appropriate splitting point is. Convene community forums and town meetings, get out the road maps, and put pen to paper to define where recognizable communities start and stop.
  • Demand and attend hearings. In several states, redistricting bodies are required to hold public hearings; in others, those in charge of redistricting may be prodded privately or publicly into allowing some forum for public input. If there are hearings, get the hearing schedule as early as possible, and mobilize community attendance: the more people who make their voices heard about the lines that would serve their needs, the more likely it is that districts eventually follow those lines. Also, it will be important to demand hearings or a public comment period not only before draft maps are produced, but afterward, to ensure that those who draw the lines hear about the impact their proposed decisions will have.
  • Present community maps to those who draw the lines. If there are public hearings, present maps of your community’s boundaries at the hearings. If not, send proposed maps to your legislators, along with petitions showing numerical support for the districts you prefer. As above, the more you can emphasize the maps that should be drawn, the more likely they are to be reflected in the final product.
  • Develop alternative maps. You may also want to step beyond maps of local communities, to redistrict the state (or city, or county) as a whole. Those who are drawing the lines have to develop multiple maps in a relatively short period of time. If you are able to give them a model, they will be able to use that model as a reference point. And in the event that the maps they draw end up in court, courts will often look to alternative maps for guidance.
  • Educate the media. Media outlets — particularly print and web media — are usually wary of self-interested government actors, and will be very interested in the redistricting process as it unfolds, and in the political impact of the final maps. Few, however, understand the redistricting process in detail. You have an opportunity to educate the media, to let them know about how the redistricting process works, and how you think it should work, to drive media coverage of the process to focus on the goals you think most important.

    Where do I get the 2010 population data for each of counties? Are there numbers on the current Ohio Senate and Ohio House current maps? Where?

  2. Jim Slagle says:

    Our redistricting competition software contains population and political index for each current district, each county, and each smaller unit (township, municipality, census block).

    Go to the competition page ( Click the Draw Your Map block. Sign into District Builders and call up a plan. Click on the Info tab and click onto a county on the Ohio map for population and political index for the county.

    For information on current Senate and House districts, when you select a plan, call up a current senate or house template. When you upload the plan, the stats panel on the right hand side of the screen will provide the population for each current district.

    Also, the Census Bureau website contains an interactive map, which allows you to click on each county for 2010 population – but no political index.
