THE CRIMINOGENIC EFFECTS OF IMPRISONMENT: EVIDENCE FROM STATE PANEL DATA, 1974–2002

Research Summary: The heavy reliance on the use of incarceration in an attempt to address the crime problem has resulted in a dramatic growth in the number of state prisoners over the past 30 years. In recent years, however, a growing concern has developed about the impact that large numbers of offenders released from prison will have on crime rates. Using a state panel data set for 46 states from 1974 to 2002, this study demonstrates that although prison population growth seems to be associated with statistically significant decreases in crime rates, increases in the number of prisoners released from prison seem to be significantly associated with increases in crime. Because we control for changes in prison population levels, we attribute the apparent positive influences on crime that seem to follow prison releases to the criminogenic effects of prison. Policy Implications: Policy makers should continue to serve the public interest by carefully considering policies that are designed to reduce incarceration rates and thus assuage the criminogenic effects of prison. These policies may include changes in sentencing, changes in probation and/or parole practices, or better funding of reentry services prerelease and postrelease.
