The Idaho Inmate Population
The statewide Idaho inmate population is not one roster. County sheriffs operate local jails for new arrests, pretrial custody, short local sentences, warrants, holds, and transport. The Idaho Department of Correction, abbreviated IDOC, operates the state correctional system for people under state prison, probation, parole, retained-jurisdiction, parole-violator, community reentry, county-jail contract, or out-of-state contract status.
The Idaho Department of Correction homepage shows the statewide agency entry point for Resident/Client Search, prisons, probation and parole, and official IDOC navigation.
That statewide agency page is the starting point for the IDOC side of the Idaho inmate population, while county sheriff pages remain separate.
IDOC's FY25 Incarcerated Population Report counted 9,938 incarcerated people on June 30, 2025, up from 9,708 on June 30, 2024. That statewide prison-system count includes term residents, retained-jurisdiction riders, and parole violators. County jail custody is more local and more variable: some counties publish online rosters, some use regional or contract beds, and some route users through the sheriff's custody desk rather than a live public list.
Idaho Inmate Population Statistics
The strongest statewide number in the research is the IDOC incarcerated population as of June 30, 2025. IDOC reported 8,168 term residents, 1,264 retained-jurisdiction riders, and 506 parole violators. The same report said 75.3% of residents were housed at in-state prison facilities, 6.4% in community reentry centers, and 16.6% in contracted beds, including county jails and Saguaro Correctional Center in Arizona.
The IDOC Research and Statistics page is the public path to population reports, dashboards, legislative reports, and related statewide correctional data.
That research page is why the statewide count is treated as a dated population report instead of a live jail roster.

Idaho Inmate Population Trends
IDOC reported a 2.4% net increase in the incarcerated population from June 30, 2024 to June 30, 2025. Term residents increased 4.4%, riders decreased 12.0%, and parole violators increased 12.2%. IDOC's FY 2026-2029 strategic plan says the incarcerated population had climbed for four years by FY25, exceeded pre-COVID levels by 3.4%, and was above the in-state capacity figure of 8,232.
| Date | IDOC Incarcerated Population | Notes |
|---|---|---|
| June 30, 2024 | 9,708 | Prior-year comparison in FY25 report |
| June 30, 2025 | 9,938 | 2.4% net increase |
| FY25 capacity frame | 8,232 | IDOC strategic plan capacity figure; county jails and out-of-state placements absorbed overage |
Who Makes Up the Idaho Inmate Population
The FY25 IDOC report gives statewide prison-system demographics, not a live combined county-jail census. It reported that 85.5% of the incarcerated population was male, the largest age group was 35 to 44 at 32.5%, and 85.0% of the total incarcerated population was White and non-Hispanic. Custody status matters as much as demographics because a rider, parole violator, county jail detainee, and sentenced term resident can appear in different systems.
- State custody: IDOC counted term residents, retained-jurisdiction riders, and parole violators in the June 30, 2025 incarcerated population.
- Facility placement: IDOC reported in-state prisons, community reentry centers, out-of-state beds, and county jails as placement categories.
- County custody: county jail rosters cover recent bookings, local holds, pretrial custody, and short jail sentences county by county.
- Federal and immigration custody: BOP and ICE systems are separate from Idaho sheriff and IDOC records.
Idaho Prison and Jail Capacity
IDOC's FAQ says nine state-owned prisons and five reentry centers house about 8,000 incarcerated individuals, with some people held in county jails and, when necessary, out-of-state contract facilities. IDOC's strategic plan described capacity of 8,232 at the end of FY25 while the incarcerated population neared 9,900. That capacity pressure explains why county jails and Arizona contract placements appear in a statewide Idaho inmate population discussion even though they are not Idaho state-owned prisons.
Laws Governing Idaho Inmate Records
Idaho public records are governed primarily by Idaho Code Title 74, Chapter 1. Idaho Code 74-102 creates the general right to inspect and copy public records unless an exemption applies. Idaho Code 74-103 governs response timing and denials. Idaho Code 74-124 is especially important for jail and arrest records because it allows withholding of investigatory law-enforcement records when disclosure would cause listed harms, while preserving access to basic arrest facts.
Key statutes and rules:
Idaho Code 74-102 covers inspection, copying, and public-record fees.
Idaho Code 74-103 covers agency response timing and denial procedure.
Idaho Code 74-124 covers law-enforcement investigatory-record exemptions and basic arrest-information carveouts.
Idaho Court Administrative Rule 32 governs court records, which are searched through iCourt or requested from the filing court rather than handled only as executive-branch public records.
The Idaho State Prison System
The Idaho Department of Correction runs state prisons, community reentry centers, probation and parole, and management services. Its locations include prisons in the Boise/Kuna area, Cottonwood, Orofino, Pocatello, St. Anthony, and IDOC contract placements in Arizona. Community reentry centers are listed for Boise/Kuna, Idaho Falls, Nampa, Twin Falls, and Pocatello. The official IDOC Resident/Client Search is the statewide search route for people under IDOC jurisdiction.
The IDOC Locations page shows how Idaho separates prisons, reentry centers, district offices, and administration across the state.
That locations list explains why the statewide facility directory includes IDOC institutions and reentry centers alongside county jails.
Idaho Inmate Population Terms
Several Idaho custody terms affect where to search and how to read a result. A retained-jurisdiction rider is not the same as a county jail detainee. A parole violator may be held in a county jail while the parole process moves. A community reentry center is part of IDOC's custody footprint, but it is not a local jail roster. These terms explain why the Idaho inmate population can appear in more than one system during the same case.
- Retained jurisdiction
- An Idaho sentencing status, often called a rider, where the court keeps jurisdiction while IDOC assesses and programs the person.
- Parole violator
- A person accused of violating parole conditions, often held temporarily pending hearing, reinstatement, revocation, or movement.
- Community reentry center
- An IDOC residential facility for structured transition, work release, treatment, life skills, and release planning.
- County jail hold
- A local custody status tied to a county booking, warrant, bond, transport, or another agency's request.
How to Search the Idaho Inmate Population
An Idaho inmate search works best when the first question is custody stage. A person arrested today may be on a county roster or recent-booking report. A person sentenced to state custody, placed on felony supervision, retained jurisdiction, parole, parole violation status, county-jail state hold, or contract placement may be in IDOC Resident/Client Search. Filed criminal charges and hearings belong in iCourt.
The IDOC Resident/Client Search page shows the official statewide fields for last name, first name, and IDOC number.
Use that form for IDOC jurisdiction; a person booked into a county jail still has to be checked through the county that holds the booking record.
- Use the county roster or sheriff custody desk for a recent arrest or local jail hold.
- Use IDOC Resident/Client Search for state custody, probation, parole, retained jurisdiction, or parole-violator status.
- Use Idaho iCourt for public court case information after charges are filed.
- Use BOP Inmate Locator for federal prison custody and ICE ODLS for immigration detention.
- Use Idaho VINELink for custody and court notifications where registration is available.
Find an Inmate by County
County jail roster lookup is the right path for recent bookings, pretrial custody, local sentences, municipal holds, and many warrant holds. Every Idaho county has its own local instructions, and some counties use regional or contract housing instead of a full local online roster.
State, Federal, ICE, and VINE Search Channels
IDOC is the state correctional source; BOP is the federal prison source; ICE ODLS is the immigration detention source; VINELink is a notification channel tied to participating jail, prison, and court systems. None of those tools replaces the county roster for a new local booking, and none should be treated as a guaranteed real-time release calculation.
The Federal Bureau of Prisons inmate locator is the separate federal search channel for people in BOP custody or with a BOP record.
That federal locator is useful for Idaho residents only when the custody record is federal, not when the person is held by an Idaho county or IDOC.
The USAGov ICE detainee instructions explain the search information needed for immigration detention lookup.
That source supports treating ICE custody as a separate lookup path from county criminal custody and IDOC records.
The Idaho VINELink portal provides the public notification entry point for custody and court notifications.
VINELink helps with notices, but the originating jail, court, or IDOC record remains the source to verify status.
Idaho Detention Facilities
Idaho holds its inmate population across county jails, sheriff custody functions, regional juvenile detention centers, IDOC prisons, IDOC community reentry centers, IDJC juvenile correctional centers, tribal holding, ICE-use county facilities, and out-of-state IDOC contract facilities.
The statewide facility roll-up preserves important routing details from the county research. Camas County is treated as a sheriff intake and transport route, while Franklin County uses contract placement context. Teton County points to Madison County jail agreement context, Oneida County points toward Caribou County Jail, and Lewis County research notes local closure context with Nez Perce as a practical fallback. Those rows are not filler. They keep the Idaho inmate population search tied to the facility that may actually hold the person.
Idaho Inmate Population FAQ
How big is the Idaho inmate population?
IDOC counted 9,938 incarcerated people as of June 30, 2025, in its FY25 Incarcerated Population Report. That number is for IDOC incarcerated status and does not function as a live total of every person held in every county jail at the same moment.
How do I find which county jail holds an inmate?
Start with the county of arrest, court case, residence, or agency involved. Then use the County Directory to reach that county's jail roster or custody instructions. If the person has moved into state custody, search IDOC.
The Idaho iCourt portal is the statewide public case-search gateway when the question moves from custody to filed charges or hearings.
Checking iCourt alongside custody records helps separate the jail roster from the criminal case record.
What is the difference between a county jail roster and IDOC?
A county jail roster is local custody, usually for recent bookings, pretrial detention, short sentences, and holds. IDOC is statewide correctional jurisdiction for state prison, retained jurisdiction, parole, probation, parole violators, reentry centers, and some contract placements.
