San Bernardino County Inmate Population Overview
San Bernardino County's local jail system is operated by the San Bernardino County Sheriff's Department Corrections Bureau. The county jail side of the San Bernardino County inmate population is housed in four sheriff-run facilities: West Valley Detention Center, Central Detention Center, Glen Helen Rehabilitation Center, and High Desert Detention Center. Those facilities hold adults in pretrial custody, local sentenced custody, classification housing, program units, and people being moved to or from court. They are not the same as CDCR prisons, federal custody, or civil immigration detention.
The official facility pages give the strongest verified baseline for jail capacity. They do not give a single live countywide inmate census in the inspected material, so capacity should not be read as the current jail count. A person arrested by the sheriff, a city police department, CHP, or another local agency may enter the county jail system first. If a felony sentence later sends that person to state prison, the public lookup path changes to CDCR CIRIS. If the custody is federal or immigration based, the BOP locator or ICE ODLS is the right source.
San Bernardino County Inmate Population Statistics
The sheriff's facility pages list 7,911 mapped county jail beds across the four main county detention sites. That number is the combined rated bed capacity from the official pages inspected on May 31, 2026, not the San Bernardino County inmate population on any given day. The California BSCC Jail Profile Survey is the state source for monthly and quarterly county jail population data, and BSCC notes that local agencies report the data, that some items are monthly while others are quarterly, and that the live database can be revised.
| Measure | Figure | Source / Date |
|---|---|---|
| West Valley Detention Center capacity | 3,347 beds | Sheriff facility page, inspected 2026-05-31 |
| Central Detention Center capacity | 930 beds | Sheriff facility page, inspected 2026-05-31 |
| Glen Helen Rehabilitation Center capacity | 1,446 beds | Sheriff facility page, inspected 2026-05-31 |
| High Desert Detention Center capacity | 2,188 beds | Sheriff facility page, inspected 2026-05-31 |
| Combined mapped county jail capacity | 7,911 beds | Research sum of official facility capacities |
The BSCC Jail Profile Survey page is shown in the manifest as the population data source.
Use BSCC for jail population trend data, then use the sheriff's own facility pages for local capacity and facility role details.
San Bernardino County Inmate Population Trends
The inspected research did not extract a five-year San Bernardino County average daily population table from BSCC. That gap matters because jail capacity, booking volume, and daily population are different measures. BSCC states that its Jail Profile Survey has been conducted since the mid-1970s and is used by local jurisdictions to track population change, program needs, and facility needs. It also states that data were available through 2025 Q4 and updated March 17, 2026.
| Trend Source | Use | Limit |
|---|---|---|
| BSCC Jail Profile Survey | County jail population, capacity, gender, and disposition filters where available | Reported by local agencies and not audited by BSCC |
| Sheriff facility pages | Facility capacity, programs, annual processing notes, local jail roles | Not a live countywide census |
| BJS Annual Survey of Jails | National comparison context | Not a San Bernardino County roster count |
| Jail Data Initiative or Vera | Trend context if dated and defined | Must not replace official county or BSCC figures without explanation |
San Bernardino County is the largest county by land area in the contiguous United States, and the sheriff's jail map reflects that geography. Rancho Cucamonga, downtown San Bernardino, Glen Helen/Devore, and Adelanto each serve different custody and transport needs. That spread can change where a person is housed without changing the fact that the record remains a county jail record.
San Bernardino County Jail Capacity
Capacity in San Bernardino County is facility specific. West Valley is the largest county jail and the core public fallback named by the roster when a person does not appear online. Central Detention Center has a downtown and federal-transport history. Glen Helen is the strongest local program and sentenced-county-custody facility. High Desert Detention Center serves the High Desert region and must not be confused with the Adelanto ICE Processing Center.
Several facility pages give operational detail that helps explain pressure on the inmate population. West Valley's official page says the facility completes 50,000 to 60,000 bookings and releases each year, more than 600 people work there, and the facility handles remote video court assignments for several courts. Central's page says it processes more than 20,000 inmates annually and houses both county and federal populations. Glen Helen's page gives an average daily population of 800 male and female inmates and describes work release and electronic confinement options.
San Bernardino County Jail Data Laws
California law shapes what the public can see about the San Bernardino County inmate population. The jail roster is a public custody tool, but it is not a full police report, a full court docket, or a guarantee that every name will be displayed. The roster itself warns that some names may be omitted under law-enforcement public-record exemptions and that court appearance dates may not be current.
Key statutes and rules:
Government Code 7920.000 is part of the California Public Records Act framework for public access unless an exemption applies.
Government Code 7923.600 governs law-enforcement investigatory records and the required or limited release of arrest information.
Penal Code 4000 authorizes county jails for people lawfully committed to local jail custody.
Penal Code 10008 requires law-enforcement agencies to post specified in-custody death information.
For local transparency, the sheriff's AB 2761 in-custody death release table lists incident date, type, case number or pending status, facility, address, and update date. That table is a public reporting source, not a population denominator.
Search San Bernardino County Inmates
The official County of San Bernardino Inmate Locator is the starting point for current county jail custody and some released-custody searches. It supports booking-number search and name search. The profile can show booking number, sex, name, alias, date of birth, age, physical descriptors, arrest date, arrest agency, housing facility, bail, visiting information, mailing address, projected release date, release data, VINELink notification, and dynamically loaded charges or holds.
- Open the official Inmate Locator directly, not a search result or commercial listing.
- Use the 10-digit booking number if known, then complete the reCAPTCHA if the booking search asks for it.
- If the booking number is unknown, enter last name, first name, date of birth, and gender. Use approximate age only when DOB is not known.
- Compare age, sex, arrest date, arrest agency, and housing facility before assuming a common-name match is the right person.
- Use the Superior Court portal for current court dates because the roster warns court dates may not be current.
- If the name is missing, call West Valley Detention Center, check release-date links, use the sheriff's public-records process, and check CDCR, BOP, or ICE if the custody type has changed.
The official Inmate Locator screenshot shows the roster entry point and search choices.
The roster is strongest for county jail custody, while court filings, state prison records, federal custody, and ICE custody each require a separate system.
San Bernardino County Roster Fields
The search form is unusually specific. A booking-number search expects a 10-digit number. A name search uses last name, first name, date of birth or approximate age, and gender. The age option searches two years before and two years after the age entered, which helps when date of birth is unknown but can also create close-name matches.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Booking # | Text | Required for booking search | 10 digits, numbers only, maxlength 10 |
| Last | Text | Practical name search field | Maxlength 16 |
| First | Text | Listed in page instructions | Maxlength 10 |
| Middle | Text | No | Maxlength 10 |
| DOB | Date text | Required unless age is used | Date of birth field, maxlength 10 |
| Age | Numeric | Substitute for DOB | Search expands two years before and after entered age |
| Gender | Radio | Yes/default | Male is checked by default; Female is available |
San Bernardino County Custody Systems
One person can move through more than one record system. The county roster may show an arrest and jail housing first. The Superior Court portal may show formal charges after the District Attorney files a case. CDCR CIRIS may show the person after a state-prison transfer. BOP or USMS channels may apply to federal custody, and ICE ODLS applies to civil immigration detention. VINELink is a notification tool rather than the primary record source.
| Custody Type | Primary Source | What It Covers |
|---|---|---|
| County jail | San Bernardino Inmate Locator | Current and recent county jail custody, housing, bail, visiting, mailing, release links |
| State prison | CDCR CIRIS | Sentenced state prisoners, CDCR number, current location, commitment county, parole-hearing data where applicable |
| Federal custody | BOP Inmate Locator | Federal BOP custody and some federal release history |
| Immigration detention | ICE ODLS | Civil immigration detainees searched by A-Number/country or biographical information |

San Bernardino County Inmate FAQ
How big is the San Bernardino County inmate population? The verified research captured 7,911 mapped county jail beds, but not a live countywide jail census. Use BSCC for current county jail population data and the sheriff's pages for facility capacity.
Why does a person disappear from the jail roster? Release, transfer, spelling or age mismatch, public-record withholding, state prison transfer, federal custody, or ICE custody can all explain a missing name.
Where are past inmates searched? The roster exposes out-of-custody release-date links, but historical booking records may require a Sheriff's public records request.
Where are filed charges searched? Use the court records after jail arrest pathway because the jail roster is not the final source for filed charges and court dates.
