Help End Prison Gerrymandering Prison gerrymandering funnels political power away from urban communities to legislators who have prisons in their (often white, rural) districts. More than two decades ago, the Prison Policy Initiative put numbers on the problem and sparked the movement to end prison gerrymandering.

Can you help us continue the fight? Thank you.

This table draws data from three sources:

  • Federal prisons on April 1, 2010: The Prison Policy Initiative downloaded the weekly population list from the Bureau of Prisons for that date on April 4, 2010.
  • State and federal correctional facilities on December 30, 2005 were extracted from: United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics. Census of State and Federal Adult Correctional Facilities, 2005 [Computer file]. ICPSR24642-v2. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 2010-10-05. doi:10.3886/ICPSR24642
  • Local jails on March 31, 2006 was extracted from: United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics. Census of Jail Facilities, 2006 [Computer file]. ICPSR26602-v1. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 2010-01-26. doi:10.3886/ICPSR26602

Military prisons and state halfway houses are not included in the above table as we were not able to locate an appropriate national database of these types of facilities. Juvenile facilities are not included in the above because the Census Bureau counts these facilities separately from the adult correctional institutions that are the focus of our work. Where necessary, state-specific sources will be more useful for identifying juvenile facilities.

We do, however, have a list (without population information) of all federal halfway houses as of March 2010.

For state, federal and local prisons built or expanded in the latter half of the decade, you may find this list of New and Expanded Prisons Since 2000 helpful as well.
