Stanford Center on Poverty & InequalitySince the mid-1970s, the United States has experienced a precipitous rise in incarceration, with about 2.3 million U.S. adults now incarcerated in state and federal prisons. In recent years, there has been increasing pressure to wind down this commitment to mass imprisonment, and it’s accordingly important to study ways to reintegrate successfully. The Incarceration RG is tasked with monitoring and evaluating the relationship between poverty and sentencing, parole reform, probation, reintegration, and recidivism.
