I need your help. For more than a decade, the Prison Policy Initiative has been at the forefront of the movement to expose how mass incarceration undermines our national welfare. With a lot of hard work and generous support from a small network of individual donors, we've won major civil rights victories in local governments, state legislatures and even the Supreme Court. But our long-term viability depends on people like you investing in our work.

Can you stand up for smart and effective justice policy by joining our small network of donors today? You can make a one-time gift, or even become one of our sustaining monthly donors.

Through the end of 2014, your contribution to our work will stretch twice as far thanks to a match commitment from a small group of other donors like you.

I thank you for your investment in our work towards a more just tomorrow.

Fixing prison-based gerrymandering after the 2010 Census: A 50 state guide

by Peter Wagner, Aleks Kajstura, Elena Lavarreda, Christian de Ocejo, and Sheila Vennell O'Rourke, March 2010

The 2010 Census will be counting more than 2 million incarcerated people in the wrong place. The laws of most states say that a prison cell is a not a residence, but the Census Bureau assigns incarcerated people to the prison location, not their home addresses. When state and local governments use this data to draw legislative districts, they unconstitutionally enhance the weight of a vote cast in districts that contain prisons and dilute those cast in every other district.

Click on a state for a summary of how the prison miscount harms state and local democracy, how each state defines residence for incarcerated people, and the status of reform efforts.

Project overview:

What the Census Bureau is doing differently in 2010

  • Not changing how it counts incarcerated people. They will still be counted as residents of the prisons, but the Census will be:
  • Speeding up publication of its data on prison populations, so that states can use it in conjunction with their own data to assign incarcerated people to their home addresses, or assign prisoners to an unknown address so that they do not affect the redistricting formulas, or leave the prisoners counted where the prisons are. (In previous decades, this data was published too late to be useful.)

What states and local governments are doing differently in 2010

  • Some states have pending legislation to change where incarcerated people are counted for redistricting purposes.
  • Some local governments are exploring adjusting the prison counts on their own, like 100 counties already do.
