The US criminal justice system is commonly referred to as a revolving door due to its high rates of recidivism―the tendency of people convicted of crimes to face more criminal charges in the future. A key question for policymakers is whether the criminal justice system itself contributes to this pattern or whether it is driven by external factors such as addiction, mental health, neighborhood disadvantage, or limited labor market opportunities. Previous research on the role of contact with the criminal justice system has focused primarily on how incarceration affects recidivism. However, noncarceral conviction (i.e., a conviction that does not result in incarceration) is also a frequent outcome. In 2010, 2.7 people were on probation for every person who was incarcerated.
