I need your help. Prison gerrymandering gives extra political power to legislators who have prisons in their districts. We put numbers on the problem and sparked a movement to protect our democratic process from the overgrown prison system.

Can you help us continue the fight? Thank you.

—Peter Wagner, Executive DirectorDonate

Getting started

The Prison Policy Initiative organized this website to be the starting point for anyone interested in learning more about the problem of prison gerrymandering.

We've generated dozens of state-by-state and district-by-district reports, hundreds of articles and fact sheets organized on state pages and in the blog. This page gives access to the same content and tools organized by topic and need.

What's your goal?

Learn the basics:

Get involved:

  • States with active campaigns against prison gerrymandering are listed on our take action page. Each state has a frequently-updated list of resources about the problem and organizing in that state.
  • Legislation page with active legislation, and past legislative efforts.
  • Model legislation for states and counties.
  • Resolutions page for non-binding organizational and legislative statements.

Use data and tools for demographers, redistricting professionals & advocates:

  • Locator (2010) (annotations and correctional facility counts by Census block, searchable by county)
  • Map files (shapefiles and kml) (a national point shapefile with the group quarters – including correctional facilities – populations, and Google Earth files that allow you to view the information available in our Correctional Facility Locator through Google Earth)
  • The Racial Geography of Mass Incarceration (Report analyzing the degree to which incarcerated people differ by race and ethnicity from the county they are incarcerated in.) See also Too Big to Ignore (report analyzing how the U.S. Census practice of tabulating incarcerated people as residents of the prison county distorts statistics for county populations)
  • Democracy Toolkit (training on using our research tools and how to analyze the impact of prison gerrymandering on local governments)
