Oneida County Inmate Population Overview
Oneida County is different from many Idaho counties because the county does not run its own jail. The official Oneida County Sheriff detention page says the county has no jail or other holding facility and that incarcerated people are taken to Caribou County Jail in Soda Springs. That fact controls the Oneida County inmate population. The local sheriff remains the arresting and records-contact agency, but the person who must be held is physically booked and housed by the neighboring jail.
The practical count is split in two ways. Oneida County has no local jail capacity to count, while Caribou County Jail is the facility that serves Oneida arrests when custody is required. Once a person is sentenced to Idaho state custody, the record may leave the jail workflow and appear in the Idaho Department of Correction Resident/Client Search. Federal sentences and immigration detention use still different systems, so a single Oneida County jail search can miss a person who has moved.
Why Oneida County Uses Caribou Jail
Oneida County's sheriff and court records are centered in Malad City, but jail custody is centered in Soda Springs. The sheriff office is in the lower level of the Oneida County Courthouse, and that office is the local point for arrest reports, records requests, and arresting-agency questions. The custody question moves to Caribou County Jail when a person is actually held. This two-location setup is the reason searches for a Malad City jail roster can fail even when the arrest happened in Oneida County.
The regional arrangement is supported by Caribou's own jail page. It says the jail houses Caribou County inmates, contract inmates from other Idaho counties, and Idaho Department of Correction contract inmates. That broad population scope fits Oneida County's published direction. A person arrested by Oneida County Sheriff may be at Caribou County Jail before first appearance, while another person from the same case can later be in IDOC custody after sentence.
The official Oneida detention page is the key source for the no-jail fact.
That screenshot matters because it explains why the inmate population page must send custody questions to Caribou County Jail rather than to a Oneida jail lobby.
Oneida County Inmate Population Statistics
The official Oneida-specific jail numbers are limited because no Oneida jail exists. The most accurate local data point is zero county jail facilities and zero Oneida-operated jail beds. The serving facility data comes from the Idaho Sheriffs' Association jail directory, which lists Caribou County Jail with a rated capacity of 49 and an average daily population of 33. Those Caribou numbers are not Oneida-only detainee counts, since the jail also holds Caribou, contract county, and IDOC contract inmates.

Oneida County Inmate Population Trends
The clearest Oneida County trend is operational, not a year-by-year jail headcount. The county still publishes that it has no jail or holding facility, so the local capacity trend remains zero county beds. Population context comes from Census QuickFacts, Caribou's jail directory entry, and IDOC statewide reports. The research did not locate Oneida-only annual bookings, Oneida-only average daily population at Caribou, or average length of stay.
| Year | Measure | Figure / Note |
|---|---|---|
| 2020 | Oneida County Census population | 4,564 residents |
| 2024 | Oneida County population estimate | 4,976 residents |
| 2025 | Oneida County population estimate | 5,085 residents |
| 2025/2026 | Oneida jail capacity | No jail or holding facility published by Oneida Sheriff |
| 2025 | Caribou serving jail | 49 rated beds and 33 average daily population |
| 2025 | IDOC statewide population | 9,938 incarcerated people as of June 30, 2025 |
Note: Caribou's average daily population does not prove the daily count for Oneida detainees because Caribou houses several custody groups.
Who Makes Up Oneida County Custody
Published sources do not break the Oneida County inmate population into pretrial, sentenced, sex, age, charge level, or race categories. Caribou County Jail reports that it can house both male and female inmates in minimum, medium, and maximum security settings. It also says it holds contract inmates from other Idaho counties and IDOC contract inmates. That means a person at the serving jail may be there for a new arrest, a short local jail term, a contract hold, or a state-custody reason.
- Pretrial
- A person held before final case disposition or before bond/release terms are satisfied.
- Contract inmate
- A person held for another county or agency under a housing arrangement.
- IDOC custody
- State prison, probation, parole, rider, or other Idaho Department of Correction jurisdiction.
Oneida County Jail Capacity
Oneida County's physical jail capacity is zero because the county does not operate a jail. Caribou County Jail's rated capacity is 49, and the Idaho Sheriffs' Association directory lists an average daily population of 33. On those two Caribou figures alone, the reported average is below rated capacity. That does not prove there are no high-population days, classification limits, medical holds, or housing pressures. The research did not locate a current Oneida jail construction plan, consent decree, overcrowding lawsuit, or Oneida-specific jail reform report.
The Idaho Sheriffs' Association jail directory shows the Caribou capacity and average daily population used for the Oneida County inmate population context.
The directory screenshot supports the capacity and average daily population figures, while the Oneida-specific detainee count remains unpublished in official sources.
Laws Governing Oneida County Inmates
Idaho public-records law gives the starting rule for access, but it also permits limits when a record is investigatory, protected, sealed, juvenile, medical, or otherwise exempt. That distinction is important for Oneida County inmate population records because a custody call may be simple, while a booking photo, full arrest report, or investigative file can require a records request and review. Court records use a separate public-access rule through Idaho courts.
Key statutes and rules:
Idaho Code 74-102 gives the public a right to inspect and copy public records unless another law limits access.
Idaho Code 74-103 sets the public-records request and response process for Idaho agencies.
Idaho Code 74-105 includes law-enforcement exemptions that can affect arrest reports and booking-photo requests.
Idaho Court Administrative Rule 32 explains why some sealed or exempt court records do not appear in iCourt.
Idaho Code 19-4301 requires coroner investigation when a death occurs while a person is incarcerated.
Search the Oneida County Inmate Population
No official Oneida County online roster was located. That absence matches the county's no-jail status. Start with the type of custody question. If the issue is a new arrest, call Oneida County Sheriff for arresting-agency records and Caribou County Jail for physical custody. If the person has been sentenced to state custody, search IDOC. If the person has a filed criminal case, search iCourt for the court record rather than the jail roster.
- Call Oneida County Sheriff at 208-766-2251 for arrest, incident, and sheriff-records questions.
- Call Caribou County Jail booking desk at 208-547-3094 for current housing, visits, money, and bond status.
- Search Idaho iCourt after charges are filed and indexed.
- Use IDOC Resident/Client Search for state prison, probation, parole, rider, or discharged status.
- Use BOP, ICE ODLS, and VINELink Idaho when those custody channels fit.
Oneida County Inmate Record Lookup
Because Oneida has no online jail roster, there is no Oneida roster field set to copy. A phone inquiry or records request should still be specific. For a Caribou custody call, provide the full name, date of birth if known, arresting county or agency, and an approximate booking date. For IDOC, the official search form accepts a last name or IDOC number and can also use a first name to narrow results.
| Channel | Search Fields | What It Covers |
|---|---|---|
| Caribou booking desk | Name, date of birth, arresting county, booking date if known | Current county-jail custody for Oneida detainees |
| IDOC Resident/Client Search | Last name, first name, or IDOC number | State prison, probation, parole, rider, and discharged names |
| BOP Inmate Locator | Name or federal number, with optional age, race, and sex | Federal custody from 1982 to present |
| ICE ODLS | A-Number and country of birth, or exact name and birth details | Current immigration detention search |
Oneida County Arrest Court Records
Custody records and court records answer different questions. The jail can confirm whether a person is held. The court record shows what charges have been filed, the case number, hearings, judge, case status, and public filings. The court records after jail arrest page covers that path in more detail. A booking charge may change after the Oneida County Prosecuting Attorney's Office reviews the law-enforcement report and files the case.
Idaho iCourt/Tyler portal is the statewide public case-search landing page used for Oneida County criminal cases.
The portal screenshot belongs with court-record searching because it is not a jail roster and does not confirm current housing at Caribou County Jail.
Oneida County Detention Facilities
The facility map has one serving jail. No Oneida County jail, Malad City holding facility, state prison, federal prison, ICE detention center, work-release annex, or separate regional jail inside Oneida County was found in official sources.
- Caribou County Jail - regional/contract jail in Soda Springs that serves Oneida County arrests when a person must be incarcerated.
Note: Use the Caribou jail name and address when planning a visit; a search for an Oneida County jail building can point to the wrong place.
