  1. * Data not available
  2. † Confinement rates use the average daily population (ADP) in state and local correctional facilities in the given calendar year. This includes individuals who were arrested and sentenced prior to that calendar year, as most sentences span several years. Thus, counties often house more individuals in correctional facilities than they have felony arrests, in any given year. Counties may experience no felony arrests in a given year, but still have residents serving time in correctional facilities. In addition, some counties do not have institutional facilities locally. In these cases, the rate value is not calculable, because the divisor equals 0.
  3. ‡ Counties with populations of less than 100,000 residents sometimes generate extreme anomalous rates that distort statewide and county trends. In these instances, the scale has been manually adjusted to compensate for the anomalous county rates. Hover over the county in the left side panel to see actual rate value.


Center on Juvenile and Criminal Justice

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.
