Sacramento County Inmate Population Overview
The Sacramento County inmate population is reported through several systems that are easy to confuse. The Sacramento County Sheriff's Office operates the two county jail facilities: the Sacramento County Main Jail and Rio Cosumnes Correctional Center. Those facilities hold people booked by Sacramento County agencies, pretrial detainees, county-sentenced inmates, parole violators, people waiting on state-prison transportation, and some prisoners held for other agencies. The Sheriff's jail data should not be added to the state-prison count when discussing county jail crowding. Folsom State Prison and California State Prison, Sacramento are state institutions run by the California Department of Corrections and Rehabilitation, not the county sheriff.
Jail population changes with arrests, release decisions, court calendars, sentence lengths, transfers, and alternative-custody programs. A person arrested in Sacramento County may begin in the Main Jail booking loop, appear on the sheriff's inmate information system while in custody, move to RCCC after sentencing to county jail, or leave the county roster after transfer to CDCR. Work Release and Home Detention also affect the Sacramento County inmate population because qualified sentenced people may serve through community corrections instead of a jail bed.
Sacramento County Inmate Population Statistics
Sacramento County's official jail materials identify two sheriff-operated jail facilities with a combined rated capacity of 4,005 beds. The Main Jail accounts for 2,380 rated beds, while RCCC accounts for 1,625 rated beds. County status reports show that the jail system was below rated capacity in the 2024 and first-half 2025 reporting periods, but the pressure was not spread evenly. RCCC carried a higher share of its rated capacity than the Main Jail in the July through December 2024 period.

Sacramento County Jail Population Trends
The long trend in the Sacramento County inmate population shows a lower jail count than the 2012 level, followed by a later rise from the low points seen around 2021 and 2022. The county's July through December 2024 combined jail ADP was 3,177, or about 79.3 percent of combined rated capacity. The January through June 2025 ADP was 3,265, about 81.5 percent of rated capacity. Those figures help separate current jail pressure from older crowding levels and from state prison occupancy.
| Period / Year | ADP / Count | Notes |
|---|---|---|
| 2012 | 4,309 | BSCC demographic reference data series |
| 2019 | 3,653 | Same BSCC series |
| 2020 | 3,183 | COVID-era decline noted in the research source |
| 2021 | 2,991 | BSCC note covers first three quarters only |
| 2022 | 3,315 | Vera profile using official California data |
| Jul-Dec 2024 | 3,177 | Main Jail 1,737 plus RCCC 1,440 |
| Jan-Jun 2025 | 3,265 | Jail Population Reduction Plan status reporting |
Sacramento County Jail Capacity
Capacity figures matter because the same countywide number can hide facility-specific stress. In the July through December 2024 status report, the Main Jail averaged 1,737 people, or 73.0 percent of capacity, while RCCC averaged 1,440 people, or 88.6 percent of capacity. The January through June 2025 report placed the systemwide ADP at 3,265, still below the combined BSCC rated capacity. Recent county reporting also tied jail population pressure to case processing, felony length of stay, mental health diversion, and Prop 36 bookings.
Admissions are a different measure from average daily population. Sacramento County may process nearly 27,000 bookings in a year while holding a much smaller number on an average day. The Main Jail functions as the main intake point, so its booking volume can be high even when its ADP is lower than the RCCC capacity percentage. Work Release, Home Detention, diversion programs, and transfers to CDCR all change the bed count without changing the fact that a prior booking existed.
Sacramento County Inmate Records Law
California law treats many arrest and booking facts as public, but it does not make every jail, police, medical, juvenile, or investigative record open on demand. The Sacramento County inmate population can be searched through public tools because the sheriff publishes custody information, while court records and state criminal-history records follow different rules. A roster result is a custody record. A court case is a prosecutor-filed record. A full California DOJ criminal history is a restricted fingerprint-based record, not a public name search.
Key access rules:
California Public Records Act, Gov. Code section 7920.000 names the state's public-records law.
Gov. Code section 7922.525 gives a public inspection right unless a record or part of a record is exempt.
Gov. Code section 7923.610 covers public arrest and booking information such as name, arrest facts, bail, holding location, and charges.
California Rule of Court 2.503 explains limits on remote electronic access to criminal court records.
Sacramento State Prison Population
Sacramento County is unusual because it includes major state prisons in the Folsom and Represa area. Folsom State Prison and California State Prison, Sacramento hold sentenced adult state prisoners in CDCR custody. They are not part of the sheriff's county jail ADP. The CDCR Weekly TPOP1 report dated April 15, 2026 listed Folsom State Prison at 2,812 people, 136.2 percent of design capacity, and CSP-Sacramento at 2,224 people, 121.7 percent of design capacity.
| Facility | Population | Design Capacity | Percent Occupied |
|---|---|---|---|
| Folsom State Prison | 2,812 | 2,065 | 136.2% |
| California State Prison, Sacramento | 2,224 | 1,828 | 121.7% |
Once a person is sentenced to state prison and transferred to CDCR, the county roster is no longer the right primary lookup. The CDCR CIRIS locator is the statewide search path for current prison location, CDCR number, admission date, commitment county, and parole-hearing information where available.
Search Sacramento County Inmates
The official custody starting point is the Sacramento Sheriff Inmate Information portal. It covers Main Jail and RCCC custody, and it offers two public search routes: name search and X-Reference search. Name search requires the first name, last name, and CAPTCHA. XREF search is more precise when a caller has the Sacramento County person identifier used in the public-safety system.
- Open the sheriff's Inmate Information portal and choose name search or XREF search.
- Enter first and last name for a name search, then complete the CAPTCHA challenge.
- Use the X-Reference number search if the XREF is known from prior jail mail, money, or custody paperwork.
- Read the custody profile with care because charges are the sheriff's latest known information, not the final court outcome.
- If no match appears, check release status, spelling, CDCR, BOP, ICE, juvenile confidentiality, or court filing records.
The sheriff's FAQ says detailed inmate information displays only while a person is in custody. After release, the public online record is limited to release date and time. No official refresh interval was found, so a recent booking may require a later search or a phone call to the Main Jail or RCCC.
Sacramento County Roster Fields
The Sacramento County inmate search fields are narrow, which is useful for accuracy but can frustrate broad searches. The XREF route is especially important because it stays tied to the person rather than one booking session. It is also used in mail, money, and health-contact workflows, so keeping it with custody notes can prevent delays.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| First Name | Text | Yes for name search | Use the detained person's legal first name. |
| Last Name | Text | Yes for name search | No official wildcard rule was located. |
| CAPTCHA / reCAPTCHA | Verification | Yes | Required on the name-search page. |
| X-Reference Number | Text | Yes for XREF search | Unique Sacramento County person identifier. |
The official name-search page shows the public form and CAPTCHA requirement for Sacramento County jail roster searches.
The form supports the county roster search, while the separate XREF page serves people who already know the person-specific identifier.
Sacramento County Inmate Record Details
A Sacramento County inmate record should be read as a current custody snapshot. The sheriff's FAQ supports fields such as booking or registry number, XREF, housing, charges, bail, projected release date, and release time. It also explains that one custody session can have registry-number extensions for separate warrants, arrest reports, or commitments. That is why a booking number is not the same thing as a court case number.
| Field | What It Shows |
|---|---|
| Name | Person in Sacramento County custody or recently released with limited release data. |
| Booking / Registry Number | Custody-session number with possible extensions for separate legal reasons. |
| X-Reference Number | Person identifier used for precise search, mail, money, and custody routing. |
| Charges | Most recent information known to the Sheriff's Department. |
| Bail / Total Bail | Total bail or \"Ineligible for Bail\" when a no-bail charge, warrant, or hold blocks release. |
| Housing Location | Floor, unit, and bunk information used for communication and facility routing. |
| Release Date/Time | After release, the sheriff says only release date and time remain public online. |
Sacramento County Jail vs Prison
Many failed searches come from using the wrong system. The sheriff roster is the right path for people in Main Jail or RCCC custody. CDCR CIRIS is the right path after a state-prison transfer. The BOP locator is for sentenced federal inmates and some federal custody history from 1982 forward. ICE ODLS is for current immigration detention or CBP custody held more than 48 hours. None of those systems is a complete public criminal-history search.
| Custody Type | Primary Lookup | What It Covers |
|---|---|---|
| County jail | Sacramento Sheriff Inmate Information | Pretrial detainees, county-sentenced inmates, and limited post-release data |
| State prison | CDCR CIRIS | Sentenced state prisoners and current CDCR location |
| Federal custody | BOP Inmate Locator | Federal inmates from 1982 to present, with release/location fields |
| Immigration custody | ICE ODLS | Current ICE custody and qualifying CBP custody searches |
Sacramento County Detention Facilities
The Sacramento County inmate population includes county jail facilities, alternative custody, state prisons, and federal reentry management. Each facility page should be read by facility type. County jail pages use the sheriff roster. State prison pages use CDCR. The federal reentry page uses BOP systems and does not describe a secure county jail.
- Sacramento County Main Jail - downtown intake and county jail facility for pretrial and detained populations.
- Rio Cosumnes Correctional Center - Type II county correctional center for sentenced county inmates, pre-sentence detainees, transports, and some contracted prisoners.
- Sacramento County Work Release Division - alternative custody and community correction programs, not a traditional jail-bed facility.
- Folsom State Prison - CDCR state prison for sentenced adult male prisoners.
- California State Prison, Sacramento - CDCR high-security and specialized mental-health state prison.
- Sacramento Residential Reentry Management Field Office - BOP reentry management office for federal community placements.
Sacramento County Inmate Population FAQ
How big is the Sacramento County inmate population?
The county jail ADP was 3,265 for January through June 2025 in the Jail Population Reduction Plan reporting. That figure covers the sheriff-operated jail system, not the CDCR prisons in the county. The two county jails together have 4,005 rated beds.
How do I search Sacramento County inmates?
Use the Sacramento Sheriff Inmate Information portal for Main Jail and RCCC custody. Search by first and last name with CAPTCHA, or use the X-Reference number if known. If the person has been sentenced to state prison, search CDCR CIRIS instead.
Can I find a released inmate online?
The sheriff's FAQ says detailed inmate information displays only while the person is in custody. After release, only release date and time remain public online. Older booking records may require a Records/Warrants Bureau or court records request, depending on the record type.
Are state prisoners part of the county jail population?
No. Folsom State Prison and California State Prison, Sacramento are physically in Sacramento County, but they are CDCR prisons. Their populations are state-prison figures and should not be added to the sheriff's jail ADP.
What if a Sacramento County roster search has no result?
Check spelling, recent release, transfer to CDCR, federal custody, ICE custody, juvenile confidentiality, and court records. A person may also have been cited and released without a current jail booking.
