Ending prison gerrymandering leads to new criminal justice data
by Aleks Kajstura, February 26, 2015
Yesterday, jointly with the Justice Policy Institute, we released a new report that for the first time mapped where people incarcerated in Maryland state prisons come from and how much Maryland taxpayers spend on their incarceration. The report includes detailed maps and information that can better inform investment decisions in these communities to help solve long-standing challenges and improve public safety.
The research was possible because of the data that was generated when Maryland implemented their No Representation Without Population law, ending prison gerrymandering. In order to count incarcerated people at home for redistricting purposes, the state needed to find out where incarcerated people live. Incarcerated people already had their addresses on file at the Department of Corrections, and the Maryland Planning Department mapped them all out in preparation for redistricting, then adjusted the population data the state received from the Census Bureau accordingly. By comparing the State’s list of populations and the Census Bureau’s reports we were able to show where the state focused its spending on incarceration.
As Delegate Joseline Peña-Melnyk (D-Prince George’s and Anne Arundel-21), one of the law’s lead sponsors, put it:
“I introduced the No Representation Without Population Act to provide better data for redistricting purposes, and I’m now looking forward to using all the data and information generated by this law to directly enlighten future criminal justice policy choices in Maryland.”
