By the Numbers: Parole Release and Revocation Across 50 States

Publication year: 2016
"Parole decision-making functions as a crucial mechanism channeling people in and out of prison. This report combines multiple data sources and, for the first time, provides an overview of the movements between prison and parole for each state, focusing on the decision points of parole release and parole revocation. This information allows for a comprehensive picture of each state, both as a snapshot and longitudinally. For each state, information is presented on prison and parole rates over time, the percentage of prison admissions that are due to people on conditional release, the percentage of hearings by the parole board that result in parole being granted, the rate of re-incarceration for parolees, and the percentage of parolees who exit parole due to an incarceration versus a successful completion of supervision" (website).
