This white paper discusses how state efforts to reduce the growth of prison populations can affect local criminal justice systems. Although these state strategies which typically focus on policies governing sentencing, inmate release and transfer, and supervision violation response - have the potential to greatly benefit both the offender and the community, they can strain the resources and capacity of jails, supervision officers, and community-based providers. Likewise, local actors may respond to these strategies with policies and practices that conflict with state prison population management efforts. Recommendations on how state and local stakeholders can avoid these unintended outcomes are provided.
