Data & Research


The dataset presented here assembles counts of jail and prison populations to permit description of trends in these critical measures over time, statewide and by county.

Diverse patterns among counties reflect not only differences in policy approaches, but features of the context such as the following:

The metrics provided here may raise useful questions about county-level patterns, but by themselves, do not answer those questions. No inferences about the comparative performance of counties, therefore, are warranted on the basis of these measures alone.

City Law Enforcement Funding - FY 2015-2016

The 2015 Budget Act, (Chapter 11, Statutes of 2015, Item 5227-102-0001) allocates $20 million for front line law enforcement activities. Provision 2, of Item 5227-102-0001, requires city law enforcement agencies that are recipients of this funding to provide data on the number of use of force incidents that result in death or hospitalization (defined as a patient admission to any hospital bed for treatment, regardless of the length of the hospital stay).

Not all city law enforcement agencies received funding, so the data should not be used to make statewide conclusions.

Data is available by reporting agency on the Agency Map and Agency Totals by County tabs. If data is not reported, then it will be displayed as "NR" throughout the dashboard.

Data will continue to be updated as non-reporting agencies submit data.

Police Departments used the City Law Enforcement Funding for a variety of projects. In the video linked here, the El Monte Police Department highlights a program involving young people and their parents.


City Law Enforcement Funding - FY 2016-2017

The 2016 Budget Act, Chapter 23, Statutes of 2016, Item 5227-102-0001 allocated $20 million to city police departments to increase positive outcomes between municipal law enforcement and high risk-populations. The grant required recipients to report data, and the Board of State and Community Corrections to compile and report that data to the Legislature by April 1, 2017.

The Budget Act directed the Department of Finance to work collaboratively with the California Police Chiefs Association to develop an allocation schedule that provided a minimum of 60 percent of the total funding to police departments employing 100 or fewer officers and gave further consideration to jurisdictions with:

That collaboration resulted in the disbursement of funding to 281 city police departments in 53 counties.  Provision 2 allowed those departments to use the funds to supplement, but not supplant, the following:

  1. Homeless outreach teams
  2. Crisis Intervention Training for officers
  3. Gang Resistance Education and Training (GREAT)
  4. Resources for drug-endangered children
  5. Outreach to high-risk youth
  6. Youth diversion programs
  7. Gang and violence prevention programs.

Finally, Provision 3 required agencies that receive funding to report the following, as applicable:

  1. The number of new teams established, or planned to be established
  2. The type of training and the number of peace officers trained, or planned to be trained
  3. The type of equipment or resources that were purchased, or planned to be purchased

This report provides an alphabetical list of each agency that received funding, how much funding was received, and the description provided to BSCC from each of those agencies about how they used the funds.

Performance Metrics for Community Corrections

“Performance Metrics for Community Corrections,” a report mandated by the Budget Act of 2014, outlines a set of interrelated metrics that are readily available and measurable that can assess how local community corrections systems are functioning. The county-by-county performance metrics identified address reported crime, arrests, supervision, incarceration, and local socioeconomic indicators. The socioeconomic indicators are part of the counties’ unique challenges impacting community corrections systems. To understand how criminal justice policy is working one must also consider the impact of these local conditions on the system. Taken together, these interrelated metrics can provide insight into the functioning of a county’s criminal justice system.

In addition to the report, the Board of State and Community Corrections annually updates Statewide and county-by-county data sets and tables of the performance metrics. The annual updates are designed to help counties, legislators, policymakers, researchers and other interested stakeholders assess how local community corrections systems are functioning. Having a way to analyze performance will allow policymakers to make informed decisions based on what they desire for their communities. The data sets and tables now provide data from 2007 through 2016 and compare changes since 2007.

Inmate Sterilization Procedures (SB 1135) Data Collection

As part of SB 1135 and statute 3440(d)2A, the Board of State and Community Corrections is required to collect from California county jails all relevant information regarding the sterilization of inmates. The data will include the number of sterilizations performed, disaggregated by race, age, medical justification, and method of sterilization. It shall be compiled and published annually on the BSCC website.


Forty-Two counties responded to our disaggregate data collection survey, please see Table 1 for details. Of the 42 respondents who completed the survey, one county reported inmate sterilization procedures were performed during the 2016 calendar year. Please see the Table 2 for details.

Inmate Sterilization 2016 Data Set


A two-phase data collection survey was sent to each county. Phase 1 was initial procedural contact made with each county to determine who was the designated county data reporter, how many facilities that county maintains, whether that county has an on-site medical facility that is able to perform sterilization procedures, and where such procedures were performed if not at the county's facility. Phase 2 then allowed the BSCC to determine how many inmate sterilization procedures were performed (if any) outside of the jail of the reporting county. Of those procedures, disaggregated data was then required to be reported on to the BSCC.

Phase 1: Fifty-Eight counties responded to our initial survey. None of the 58 counties performed inmate sterilization procedures at their on-site medical facilities. All respondents indicated that if such procedures needed to be performed, they would occur at a designated local hospital.

Phase 2: Fifty-Six counties responded to our disaggregate data collection survey, please see Table 1 for details. Of the 56 respondents who completed the follow-up survey, two counties reported inmate sterilization procedures having been performed during the 2015 calendar year. Please see the Table 2 for details.

BSCC Realignment Resources

In 2011, Governor Brown signed into law Assembly Bill (AB) 109 and AB 117, hereafter referred to as realignment, which made “fundamental changes to California’s correctional system to stop the costly, ineffective and unsafe "revolving door" of lower-level offenders and parole violators through our state prisons” (excerpt from Governor’s Press Release, April 5, 2011).

The Jail Profile Survey

The Jail Profile Survey, conducted since the mid-1970’s, is a data collection instrument that gathers responses from counties on local jurisdiction and county jails. This information provides counties a means of tracking changes in their populations and assessing and projecting program and facility needs. Some items are reported monthly, others quarterly; questionnaires are completed and returned to BSCC for review and public posting via the Jail Population Trends Dashboard and Jail Profile Survey Online Querying database.

The Jail Program Survey

The Jail Program Survey was a collaboration between the Board of State and Community Corrections (BSCC) and a workgroup from the California Jail Programs Association. Information contained within the dashboard was self-reported by participants who completed a 2013 Statewide Survey on the types of programs provided to offenders in California adult correctional facilities.

The AB109 Survey

Jail Population Trends Dashboard

The AB109 Jail Profile Survey is a data collection instrument completed monthly by counties to reflect the impact of AB109, specifically related to offenders sentenced Penal Code Section 1170(h) or released on Post-Release Community Supervision (PRCS) or parole status who have been admitted or detained in local detention facilities. Participating agencies collect relevant data and submit completed questionnaires to BSCC for review and public posting via the Jail Population Trends Dashboard. There are eleven items listed on the AB109 Jail Profile Survey Monthly Report Form.


The Juvenile Detention Survey

Main Juvenile Detention Profile Survey

The Juvenile Detention Profile Survey is a data collection instrument that gathers responses from counties on local juvenile detention facilities. This information provides counties a means of assessing and projecting program and facility needs. As with our other surveys, completed questionnaires are returned to the BSCC for review and public posting via the Juvenile Detention Survey Online Querying database.
