Abstract
In 2006, long-term forecasts indicated that Washington faced the need to construct several new prisons in the following two decades. Since new prisons are costly, the Washington legislature directed the Washington State Institute for Public Policy 1. The Washington State Institute for Public Policy conducts nonpartisan research at the direction of the state's legislature, and findings are used to help inform public policy makers. View all notes to project whether there are “evidence-based” options that can reduce the future need for prison beds, save money for state and local taxpayers, and contribute to lower crime rates. The institute conducted a systematic review of all research evidence that could be located to determine what works, if anything, to reduce crime. We found and analyzed 545 comparison-group evaluations of adult corrections, juvenile corrections, and prevention programs. We then estimated the benefits and costs of many of these evidence-based options and found that some evidence-based programs produce favorable returns on investment. This paper presents our findings and describes our meta-analytic and economic methods.
