New 2019 Fiscal Impact Analyses:
Prison Population Projection
Research Briefing: State Use of Electronic Monitoring
May 7, 2019

The Illinois Prisoner Review Board (PRB) asked SPAC to review a sample of orders for electronic or GPS monitoring (EM) for people leaving the Illinois Department of Corrections (IDOC) between April 1, 2018 and June 30, 2018.   SPAC reviewed the orders, linked to IDOC records, and now provides this analysis of demographics and offense characteristics of these cases.  Overall, SPAC reviewed and matched 2,191 unique orders, representing approximately 31% of the hearings held during that three-month span.   Other than the administrative data and PRB orders, SPAC had no additional information.  SPAC tracked the frequency with which EM was recommended by IDOC staff and imposed by PRB (with or without an IDOC recommendation) as well as the common factors associated with EM orders.  Our findings are detailed in the link below.

Average Offender from Prison Profiles

Offender Profiles

Who is the average inmate coming out of state prison? What crime did he or she commit? How long did he or she spend in the system? What was his or her experience? To begin answering these questions, SPAC analyzed state prison releases to create an average “profile” using the most often occurring characteristics. These 2018 profiles focus solely on those released from prison, not all convicted of felonies, but provides an update to an earlier analysis.
