View the short SPAC Prison Animation to understand how admissions and length of stay determine the size of the prison population.
To illustrate how different offense classes consume resources, SPAC analyzed the data for the average number of exits in each class for 2011, 2012 and 2013.
IDOC Admissions, Exits, and Population Pie Charts highlights data from State Fiscal Year 2016 and June 30, 2016 Admissions data.
For the first time this year SPAC is incorporating dynamic marginal costs into its analyses.
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.
