The Illinois Sentencing Policy Advisory Council's Cost Benefit Analysis 2018 Report on the High Cost of Recidivism

The Illinois Sentencing Policy Advisory Council (SPAC) released our 2018 updated cost benefit analysis report on the high cost of recidivism and the supplement that fully explains our methodology. SPAC adopted this model and requested technical assistance from the Pew-MacArthur Results First Initiative because the model has been tested and accepted in the legislative and budgeting processes in Washington State for over 18 years, it was free, and it came with a multi-disciplinary technical assistance team. Using this model allows us to apply the best national research to Illinois-specific crime data. More importantly, the model is the best tool to determine the efficient use of tax dollars to minimize the risk that crime will occur.

Offender 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, as well as average and median lengths of stay.
