I outlined recently the causes and costs of states’ high incarceration rates. While most states, under both Republican and Democratic control, have enacted criminal justice reforms in recent years to reduce prison populations without harming public safety, most states’ reforms to date haven’t been extensive enough to have a big impact on prison populations.
State policymakers need to enact reforms that target the main drivers of high incarceration rates: the number of people admitted (or re-admitted) into correctional facilities and the length of their prison stays. States should consider four basic kinds of reforms:
States can also adopt more effective probation policies. For example, Hawaii has sharply reduced probation revocations with a program that punishes infractions more quickly and with more certainty, but with much shorter periods of incarceration.
These reforms are complementary; adopting just one or two won’t shrink a state’s prison population as much as a more comprehensive set of reforms that improves “front-end” sentencing and admission policies as well as “back-end” release and re-entry policies. New Jersey, New York, and California have adopted comprehensive reforms that helped drive down prison populations in each of those states by roughly 25 percent, even as crime rates continued to fall.
