Since 1985, CJCJ has conducted premier research and policy analysis promoting more effective approaches to criminal and juvenile justice policies, which further long-term public safety. CJCJ has published numerous reports on topics ranging from juvenile justice reform to analyses of drug policy enforcement.

In 2009, CJCJ developed the California Sentencing Institute as the foundation for data and research driven commentary on the broader public policy dialogue. The interactive map presents detailed crime and incarceration numbers, rates, and trends for California and each of its 58 counties. This resource is designed to provide comprehensive analysis of sentencing policies and practices across the state.
