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.

  • Jails in Indian Country populations on June 30, 2016 were extracted from: United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics. Annual Survey of Jails in Indian Country, 2016. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 2018-05-23. doi:10.3886/ICPSR37006.v1

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 April 2, 2020 [XLSX].
