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 a decade 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.

Information about National Academies report: Once, Only Once, and in the Right Place: Residence Rules in the Decennial Census

On September 14, 2006, the National Research Council of the National Academies released its report Once, Only Once, and in the Right Place: Residence Rules in the Decennial Census. The report was prepared at the request of the Census Bureau and was written by the Panel on Residence Rules in the Decennial Census and edited by Daniel L. Cork and Paul R. Voss.

One major problem the panelists addressed was the subject addressed on this website, how prisoners should be counted in the decennial census. The report found that the "evidence of political inequities in redistricting that can arise due to the counting of prisoners at the prison location is compelling."

This page contains links to the National Research Council's report and many of the key materials they relied on to make their recomendations.
