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.

Idaho correctional populations of Census 2020 vintage

We recommend using these addresses only for guidance in identifying prison populations in the Census data and warn against assuming that the prisons were in fact counted at that particular location.

This table draws data from four sources:

  • Federal prisons on April 2, 2020: The Prison Policy Initiative downloaded the weekly population list from the Bureau of Prisons for that date.
  • State and federal correctional facilities on June 30, 2012 were extracted from: United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics. Census of State and Federal Adult Correctional Facilities, 2012. ICPSR37294-v1. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 2020-02-06. doi:10.3886/ICPSR37294.v1. County data retrieved from postal service database.
  • Local jails' average daily populations from January 1, 2013 to December 31, 2013 were extracted from: United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics. Census of Jail Facilities, 2013. ICPSR36128-V4. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 2018-04-25. doi:10.3886/ICPSR36128.v4
  • 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].
