How to Look Up LA County Jail Population Data
Three official sources hold the bulk of Los Angeles County jail population data. The Sheriff's custody reports page hosts PREA reports, targeted inspections, nutrition inspections, and other custody documents. The California Board of State and Community Corrections publishes jail inspection and standards data at the state level. The Bureau of Justice Statistics publishes the national jail inmate reports used for context.
Data on the Sheriff's custody reports page is loaded as PDFs and inspection letters. A 2025 targeted inspection letter listed inspected facilities and noncompliance items, which is useful for current compliance context but is not a clean average daily population series. BSCC jail inspection records add a state baseline. BJS reports add national comparisons.
Note: The current public material is strong on facility lists, inspections, and capacity context, but a complete five-year average daily population table with demographics was not located in the source pass, so verify exact daily counts directly with LASD or BSCC.
LASD Custody Operations Structure
LASD Custody Division Manual section 2-00/000.00 organizes operations into three branches. Custody Services Division General Population covers Men's Central Jail, North County Correctional Facility, Pitchess East, Pitchess North, Pitchess South, the Inmate Reception Center, and the Population Management Bureau. Custody Services Division Specialized Programs covers the Inmate Services Bureau, Education Based Incarceration, religious and volunteer services, fire camps, jail enterprises, Twin Towers, the Correctional Treatment Center, Century Regional Detention Facility, the Access to Care Bureau, and the Jail Mental Evaluation Team. Administration Command covers the remaining support and policy functions.
The split matters for reading population data. General Population numbers and Specialized Programs numbers move on different drivers. Mental-health placement at Twin Towers depends on classification. Fire camp counts depend on state staffing. Population Management Bureau tracks the day-to-day count and balances housing across facilities.
LA County Jail Capacity Overview
Capacity figures across the LASD jail system vary by facility and by source. The personnel handbook gives older capacity numbers for Men's Central Jail but does not provide a clean current capacity for every facility. Many capacity figures on the live custody pages are not in static text and must be checked against the latest BSCC inspection. The table below mirrors what the source material supports.
| Facility | Capacity / Population Notes | Source Status |
|---|---|---|
| Men's Central Jail | Older official LASD personnel handbook: designed for 3,323 in 1963; 1976 addition raised rated capacity to 5,276; current capacity approx. 6,750 in handbook. | Needs current BSCC/LASD verification before final live page. |
| Twin Towers Correctional Facility | LASD manual says houses all male mental-health inmates, the Correctional Treatment Center, and the most security-intensive male inmates. | Capacity not currently published in static official text. |
| Century Regional Detention Facility | Maximum-security direct-supervision facility for women. | Capacity not currently published in static official text. |
| North County Correctional Facility | General population at Pitchess. | Capacity not currently published in static official text. |
| Pitchess East | General population. | Capacity not currently published in static official text. |
| Pitchess North | General population. | Capacity not currently published in static official text. |
| Pitchess South | General population; Elmer T. Jaffe Visiting Center handles PDC visiting. | Capacity not currently published in static official text. |
| Inmate Reception Center | Intake, reception, and classification. | Capacity not currently published in static official text. |
Each row is honest about what the source material shows. Capacity numbers will need to be checked against the current BSCC profile before publishing exact daily counts. The Sheriff publishes inspection summaries but does not publish a single capacity table for the whole system in static text.
The Downtown Jail Complex
The downtown Bauchet Street complex is the largest cluster of beds in the Sheriff system. Men's Central Jail, Twin Towers, and the Inmate Reception Center all sit on the same block in central Los Angeles. People arrested across the county and booked at a Sheriff station jail are often moved to the Inmate Reception Center for medical and mental-health screening before housing assignment.
Men's Central Jail at 441 Bauchet Street is the oldest building in the complex. Twin Towers at 450 Bauchet Street opened decades later and now holds the Correctional Treatment Center and the male mental-health population. The Inmate Reception Center sits between the two. Together the three facilities account for a large share of the day-to-day population.
Pitchess Detention Center Facilities
The Pitchess Detention Center in Castaic is the second main cluster. Four facilities sit on the site: North County Correctional Facility, Pitchess East, Pitchess North, and Pitchess South. Each one is part of the General Population branch of custody. The 2025 targeted inspection letter lists Pitchess East, South, and North among the facilities reviewed for exercise time, out-of-cell time, and restraint-device use.
The North County Correctional Facility is one of the largest general-population buildings in the Sheriff system. The Pitchess facilities together carry a meaningful share of the sentenced and pretrial male count outside the downtown complex.
Mental Health Custody at Twin Towers and the CTC
Twin Towers is the Sheriff's main mental-health facility for men. The LASD manual says it houses all male mental-health inmates. The Correctional Treatment Center inside Twin Towers gives medical and mental-health care across diagnostic levels. The Jail Mental Evaluation Team works out of the complex to screen and place inmates with mental-health needs.
The Access to Care Bureau and LAC+USC Medical Center serve as the link for specialized medical care. Mental-health placement is set by Custody Division classification, often through Twin Towers. The day-to-day mental-health count is not published as a static table in the official sources reviewed, so a current figure should be verified with LASD or BSCC.
Women's Custody at Century Regional Detention Facility
Century Regional Detention Facility in Lynwood is the women's custody facility. The Sheriff's manual lists it as a maximum-security direct-supervision facility. It is responsible for booking and housing women prisoners brought in through Century Station. The facility is also covered in the 2025 targeted inspection.
The day-to-day women's population at CRDF moves on different drivers than the male population at the downtown complex. Booking volume, court calendars, and state prison transfers all play a role. The official capacity figure was not located in static current text in the source pass.
Average Daily Population Reporting
Average daily population for Los Angeles County jails is reported through a mix of LASD documents, BSCC inspection data, and federal jail surveys. A clean public table with a complete five-year ADP series and demographic breakdown was not located in static text on the official Sheriff or BSCC pages during the source pass. Where exact ADP numbers are needed, the right step is a direct request to the Sheriff's Population Management Bureau or to BSCC for the most recent jail profile.
BJS publishes the national average for jail inmate counts and jail incarceration rates each year. State-level data sits with BSCC. Vera Institute also publishes county-level longitudinal data, but Vera is not an official government source and should be treated as optional context only.
The Sheriff's Population Management Bureau coordinates the day-to-day count and balances housing across the eight facilities. The Bureau is part of the General Population branch of Custody Services.
Pretrial vs Sentenced Population
BJS national jail data shows that the pretrial share of county jail population has been the majority of the count for most years on record. The state share for California sits in the same general range. A clean current pretrial-vs-sentenced split for Los Angeles County alone was not located in static text in the official sources during the source pass.
| Status | Notes |
|---|---|
| Pretrial | Awaiting trial or first appearance; bail or release on own recognizance is the path out. BJS national context: pretrial is typically the majority of jail population. |
| Sentenced | Serving a sentence in the jail, often under realignment for Penal Code section 1170(h) terms. National BJS data: sentenced share is the minority of jail population in most years. |
| Holds | People held for another agency under a separate authority. Status not always classified as pretrial or sentenced. |
The Sheriff's Population Management Bureau is the right contact for current splits. The Sheriff's Court Services Division moves pretrial inmates to court for arraignment, hearings, and trial.
National and State Context
National jail rate data comes from the Bureau of Justice Statistics. BJS publishes the annual jail inmate count, the jail incarceration rate per 100,000 residents, and the pretrial-vs-sentenced split. State-level data for California comes from BSCC. The table below frames the three levels with source notes rather than precise numbers, since exact current rates should be pulled fresh from the source.
| Level | Jail Population Context (per 100k residents) | Source |
|---|---|---|
| Los Angeles County | One of the largest jail systems in the United States; exact rate per 100k not currently published in static official text. Verify against LASD and BSCC. | LASD custody reports; BSCC profile. |
| California | State-level jail count and rate published through BSCC jail profile and inspection data; California operates 58 county jail systems. | BSCC. |
| National | BJS publishes the national annual jail inmate count and rate per 100k residents in its Jail Inmates series. | BJS. |
BJS releases include Jail Inmates at Midyear and Census of Jails. Both are used for national context. BSCC handles the same role at the state level.
Inspection and PREA Reports
The Sheriff's custody reports page publishes PREA reports, targeted inspections, and nutrition inspections. A 2025 targeted inspection letter lists the inspected facilities: Men's Central Jail, Twin Towers Correctional Facility, the Inmate Reception Center, North County Correctional Facility, Pitchess Detention Center East, Pitchess Detention Center South, Pitchess Detention Center North, and Century Regional Detention Facility. The letter identifies noncompliance items around exercise time, out-of-cell time, and restraint-device use for certain facilities.
These reports are useful for current compliance context. They are not a clean average daily population series. Pair them with BSCC inspections and BJS annual reports for a fuller picture of the system.
Population Trends and Research Gaps
The narrative on Los Angeles County jail population is strong on structure and weak on a single live total. Custody operations span the downtown complex, the Pitchess facilities in Castaic, and Century Regional in Lynwood. Specialized mental-health and medical populations live at Twin Towers and the Correctional Treatment Center. Women's custody runs at Century Regional. The current capacity, current ADP, and current pretrial split should each be pulled from the source closest to the question.
