Bonneville County Inmate Population
The adult core of the Bonneville County inmate population is the Bonneville County Jail, operated by the Bonneville County Sheriff's Office Detention Division. The jail holds people arrested in Idaho Falls, Ammon, Iona, Ucon, Swan Valley, Ririe-area cases routed to Bonneville, and other local agencies when adult county custody applies. It also holds local sentenced inmates, work release and work detail participants, Wood Court participants, and other local holds. That makes the jail roster the first public check for most local arrests.
Other custody channels sit beside the adult jail. 3B Detention Center is secure juvenile detention, not the adult roster. Idaho Falls Community Reentry Center is an Idaho Department of Correction reentry facility for minimum-custody men nearing release. Jefferson County Jail in nearby Rigby appears in an ICE PREA audit as a regional ICE contract jail. These systems do not replace the Bonneville County jail roster, but they explain why one person may not appear in a county search.
Bonneville County Inmate Population Statistics
The sheriff reports that the current jail opened in November 1998 with 284 beds and has expanded to 533 operational beds. The Bonneville County Jail Annual PREA Stats Report 2025 gives the clearest official population series: 4,063 admissions, a 2025 average daily population of 357, and 342 people in custody on December 31, 2025. A live roster snapshot observed on June 8, 2026 listed 358 inmates, but live roster counts are volatile and can change during the day.
| Measure | Figure | Source / Year |
|---|---|---|
| Average daily population | 357 | Bonneville County Jail Annual PREA Stats Report, 2025 |
| Operational jail capacity | 533 beds | Sheriff jail page, accessed June 8, 2026 |
| Annual admissions/bookings | 4,063 | PREA Stats Report, 2025 |
| County population estimate | 135,771 | Census QuickFacts, July 1, 2025 estimate |
Bonneville County Jail Population Trends
Bonneville County jail use has not moved in a straight line. The official PREA series shows a lower average daily population in 2020 and 2021, a peak in 2022, two stable years at 323 in 2023 and 2024, and a rise to 357 in 2025. Admissions also rose from 2,340 in 2020 to 4,063 in 2025. Those figures track bookings and custody pressure better than a single roster count because an hourly roster snapshot can be affected by release timing, transport, court returns, and late-day bookings.
| Year | Dec. 31 Population | Admissions | ADP |
|---|---|---|---|
| 2025 | 342 | 4,063 | 357 |
| 2024 | 355 | 4,116 | 323 |
| 2023 | 306 | 3,725 | 323 |
| 2022 | 334 | 3,251 | 364 |
| 2021 | 300 | 3,050 | 264 |
| 2020 | 246 | 2,340 | 276 |
The 2025 ADP equals about 67.0 percent of the 533-bed operational capacity. A local East Idaho News report in October 2024 also described the jail as a 533-bed facility and said additional beds were expected, while a January 2025 report described a special housing unit with eight new quads and 168 beds for medical, mental-health, developmental-disability, and suicide-risk housing needs.
Bonneville County Inmate Demographics
The official PREA report gives a gender breakdown for the jail but does not publish age, offense type, average length of stay, or race. For 2025, the year-end jail population was 265 male and 77 female, with annual admissions of 2,861 male and 1,202 female. The ADP was 274 male and 83 female. Vera's county dataset, updated March 2026 from Bureau of Justice Statistics and supplemental sources, gives longer trend fields and a 2023 pretrial and sentenced split.
| 2025 Metric | Male | Female | Total |
|---|---|---|---|
| Dec. 31 population | 265 | 77 | 342 |
| Annual admissions | 2,861 | 1,202 | 4,063 |
| Average daily population | 274 | 83 | 357 |
Vera's 2023 Bonneville County jail snapshot listed 340 people, including 221 pretrial and 119 sentenced. Its race and ethnicity fields for 2023 listed 269 White, 46 Latinx, 11 Black, 10 Native, 0 AAPI, and 4 Other. Use that source as a research data set, not as a current live roster.
Laws for Bonneville County Jail Data
Idaho law starts with public access, then narrows access for records that are exempt, sealed, juvenile, investigative, or correctional in a way that would harm safety or privacy. That is why Bonneville County can publish a current roster with photos, inmate IDs, names, and housing labels while withholding exact charges and bond amounts from the public roster. Jail population data, booking images, case records, and records requests all move through different access rules.
Key statutes and rules:
Idaho Code 74-102 gives a right to examine and copy Idaho public records unless another law closes or limits the record.
Idaho Code 74-103 sets public-record request timing, denial, and response rules.
Idaho Code 74-106 lists exemptions that can affect investigatory, law-enforcement, and inmate-related information.
Idaho Court Administrative Rule 32 controls public access, redaction, shielding, and sealing for Idaho court records.
Search the Bonneville County Inmate Population
The official current-custody search is the Bonneville County Jail Inmate List. It is hosted by the sheriff and linked from the county's jail inmate list page, which says the roster updates once per hour. The sheriff roster also displays its own timestamp and warns that updates may sometimes fail or not occur on the hour. When a person is not listed, or when charges and bond data are needed, the sheriff directs callers to a Detention Deputy at 208-529-1315.
The roster is free and does not require a login. It is best used as a custody and location check. It is not a complete booking record database.
- Open the sheriff's inmate-list page and check the update timestamp.
- Use the roster search box to filter by last name, first name, or visible text.
- Sort columns or use pagination if the name is common.
- Read the visible image, inmate ID, name, and location fields.
- Call the jail for charges, bond, or a person who should be in custody but is not listed.
Bonneville County Roster Search Fields
The public roster uses a simple DataTable layout. It does not ask for date of birth, case number, charge, arresting agency, or booking number. That narrow search design is important because two people with similar names may need a phone confirmation through the jail before any decision is made.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Show entries | Dropdown | No | Changes how many visible roster rows display at once. |
| Search | Text input | No | Filters the visible roster by typed text. |
| Column sort | Clickable headers | No | Columns can be sorted except the image column. |
| Previous / Next | Pagination buttons | No | Moves through roster pages. |
The sheriff roster page shows the public roster with inmate images and search controls.
The image column confirms that the roster can show a booking photo, while the limited columns show why the jail phone remains the official route for charge and bond details.
Bonneville County Inmate Record Fields
A public Bonneville County inmate record is narrower than many jail profiles. The sheriff states that exact charges and bond amounts cannot be published on the inmate-list page because of the records system. Public users should treat the roster as a current custody list and use the court portal, jail phone, or records request for fuller case context.
| Field | What It Shows |
|---|---|
| Images | Booking image or mugshot thumbnail, usually sheriff-hosted. |
| Inmate ID | Jail-assigned number used for roster and mail addressing. |
| Last Name | Last name in uppercase on the roster. |
| First Name | First name on the roster. |
| Location | Housing or location label, such as dorm or work-release dorm. |
Bonneville County Past Inmate Records
Released inmates may drop from the current jail roster, and the research did not find a separate official public archive of past Bonneville County bookings. For historical booking records, police reports, or non-roster jail records, use the Bonneville County JustFOIA portal or the Sheriff's Office Records counter in the Law Enforcement Building at 605 N. Capital in Idaho Falls. The sheriff says the old downloadable records request form is no longer used as of September 3, 2025.
Idaho public-record law generally gives agencies three working days to grant or deny a resident request, or to say more time is needed. Some requests can be redacted or withheld under Idaho Code 74-106, especially active investigations, juvenile material, privacy-protected records, and nonpublic correctional information. The sheriff records page explains the local JustFOIA and in-person options.
That records page is the best official fallback when the live roster confirms too little or when a released booking is no longer visible.
Bonneville County Jail vs State Prison
Readers often search one system for every custody status, but Idaho divides custody. Bonneville County Jail is for local adult jail custody. IDOC covers sentenced state custody, probation, parole, and IDOC jurisdiction. BOP covers federal sentenced inmates from 1982 to present. ICE ODLS covers people in ICE custody or CBP custody for more than 48 hours, and it does not search juveniles.
| Custody Type | Where to Search | What It Covers |
|---|---|---|
| County jail | Sheriff inmate list | Current adult local custody at Bonneville County Jail. |
| State corrections | IDOC Resident/Client Search | Sentenced residents, probation, parole, and IDOC jurisdiction. |
| Federal sentence | BOP Inmate Locator | Federal inmates from 1982 to present. |
| Immigration custody | ICE Online Detainee Locator | Current ICE custody or CBP custody longer than 48 hours. |
Bonneville County Detention Facilities
The county facility map has four practical channels. The adult jail is primary for local arrests. The juvenile facility, IDOC reentry center, and regional ICE channel require different lookup rules and different expectations for public access.
- Bonneville County Jail holds adult pretrial detainees, local sentenced inmates, work release/work detail participants, Wood Court participants, and other local holds.
- 3B Detention Center is secure juvenile detention for Bonneville, Bingham, Butte, and contract counties.
- Idaho Falls Community Reentry Center is an IDOC minimum-custody reentry center for male residents nearing release.
- Jefferson County Jail is a nearby regional ICE custody channel identified in an official ICE PREA audit.
VINE and App Custody Updates
The sheriff links VINE Idaho for free custody and case notifications. The Idaho Sheriffs' Association also describes VINE as a statewide victim notification service. VINE is a notification tool, not the same thing as the sheriff roster or IDOC locator, so it should be used with the official lookup system for the person's custody type.
BCSO announced the Idaho Sheriff Connect mobile app on December 19, 2024. The sheriff said the free app includes jail information and inmate search, BCSO records, online crime reporting, tips, the sex offender registry, driver license and permit information, community resources, career information, and push notifications. The app is another Bonneville-specific access channel when the website is hard to use on a phone.
