The Colorado Inmate Population
Colorado does not have one public roster that combines every sheriff jail, CDOC prison, BOP institution, ICE detention site, youth center, court case, and VINE notification record. The statewide custody map is fragmented. County sheriffs operate local jail custody for recent arrests, pretrial detention, local sentences, warrants, and temporary holds. The Colorado Department of Corrections operates the state prison system for people sentenced to CDOC custody. Federal prisoners use the Bureau of Prisons, immigration detainees use ICE ODLS, and youth detention or commitment sits under the Colorado Department of Human Services Division of Youth Services.
The official Colorado Department of Corrections home page is the statewide starting point for CDOC navigation and agency context.
The screenshot shows why CDOC belongs in the statewide overview rather than on a single county roster page.
The best Colorado inmate population search starts with the custody path. A person arrested in a county last night is usually on the local jail side. A person sentenced to state prison is usually on the CDOC side after intake. A person sentenced in federal court may be in Colorado at FCI Englewood or the Florence federal complex, or may be in another state. A person transferred to civil immigration detention is searched through ICE rather than a county roster.
Colorado Inmate Population Statistics
The most current statewide prison figure in the research is CDOC's January 2026 Monthly Population and Capacity Report. As of January 31, 2026, CDOC reported 16,535 grand-total ADP populated beds against 16,961 operational capacity when adult and Youthful Offender System rows are combined. The same report showed 426 ADP vacant beds, a 2.51 percent ADP operational vacancy rate, and a separate external or non-prison inmate population table totaling 2,026.
CDOC publishes its report archive through the official statistics page.
That source is the basis for the statewide prison population and capacity figures summarized below.
| Measure | Figure | Source / Date |
|---|---|---|
| State-prison populated beds | 16,535 ADP | CDOC Monthly Population and Capacity Report, Jan. 31, 2026 |
| CDOC operational capacity | 16,961 | CDOC Monthly Population and Capacity Report, Jan. 31, 2026 |
| CDOC external / non-prison inmate population | 2,026 | CDOC Monthly Population and Capacity Report, Jan. 31, 2026 |
| County locality folders | 64 | Colorado locality directory in statewide research |
Colorado Inmate Population Trends
CDOC's June 30, 2025 report listed State & Private Prison Total facility population of 15,826 and Total Inmate Jurisdictional Population of 17,890. CDOC's June 30, 2024 report listed State & Private Prison Total facility population of 15,774 and Total Inmate Jurisdictional Population of 17,489. The year-to-year change from June 2024 to June 2025 was modest growth in physical prison facility population and a larger increase in jurisdictional population. The January 2026 ADP format shows in-prison ADP above 16,000 when adult and YOS rows are combined.
| Date | State Prison Population Measure | Jurisdictional Context |
|---|---|---|
| June 30, 2024 | 15,774 facility population | 17,489 total inmate jurisdictional population |
| June 30, 2025 | 15,826 facility population | 17,890 total inmate jurisdictional population |
| Jan. 31, 2026 | 16,535 ADP populated beds | 2,026 external / non-prison inmates reported separately |
Who Makes Up the Colorado Inmate Population
The Colorado inmate population includes several groups that should not be merged. County jail detainees may be newly arrested, pretrial, sentenced locally, held for a warrant, or waiting on transfer. CDOC prisoners are people in state-prison custody after a Colorado sentence or related CDOC status. BOP prisoners are federal, ICE detainees are civil immigration custody, and DYS youth centers are governed by stricter confidentiality rules than adult jail records.
The Colorado Division of Youth Services residential youth centers page documents the secure youth-center system that sits outside adult jail and CDOC records.
This is why youth custody is described separately from adult county jail and state-prison lookup paths.
- County jail custody: County sheriffs and local detention agencies handle local jail rosters, booking records, mugshot policies, visits, and jail records requests.
- State-prison custody: CDOC uses the statewide Offender Search for sentenced state-prison custody and CDOC statuses.
- Federal and ICE custody: BOP and ICE use national locators, not Colorado county rosters or CDOC.
- Youth custody: CDHS says DYS operates 12 secure youth centers serving youth ages 10-21 who are pre-adjudicated or committed; adult-style roster assumptions do not apply.
Colorado Prison and Jail Capacity
For CDOC, the January 2026 ADP report gives statewide capacity context: 19,241 design capacity, 17,024 funded capacity, 16,961 operational capacity, and 16,535 ADP populated beds. It also distinguishes restrictive-housing inmates, infirmary or off-grounds inmates, assigned population, vacant beds, and operational vacancy rate. County jail capacity is not presented in the statewide research as one single Colorado-wide figure, so county-level jail capacity should be checked through the relevant county page or local sheriff source instead of inventing a statewide jail total.
Laws Governing Colorado Inmate Records
Colorado public-record access for inmate and jail records is split across CORA, CCJRA, court rules, agency policy, and confidentiality laws. The Colorado Attorney General's CORA/CCJRA overview explains that CORA requests for criminal justice records are treated under CCJRA and that CCJRA disclosure is more limited than general CORA access. CDOC's own records page says it is a criminal justice agency maintaining public records and criminal justice records, and that requests are evaluated under C.R.S. 24-72-201 et seq. or C.R.S. 24-72-301 et seq.
For state-prison records, CDOC posts its criminal-justice records framework on the official CORA / CCJRA page.
The page reinforces the statewide distinction between public records, criminal justice records, and records that need agency review.
Key access rules:
Colorado Attorney General CORA / CCJRA overview - criminal justice records are handled under the more limited CCJRA framework.
CDOC CORA / CCJRA page - CDOC requests are routed to doc_open_records@state.co.us with identifying details and a clear records description.
Colorado Judicial Branch access guide - court-system public records may be limited by law, rule, court order, or public-interest grounds.
The Colorado State Prison System
CDOC's official facilities menu lists active adult state facilities, the Denver Complex, private prisons, Pueblo Campus facilities, and related facility pages. Colorado's state-prison estate includes ordinary general-population prisons, intake and reception facilities, treatment and clinical beds, women's facilities, private contract prisons, and special-mission units. CDOC intake begins at the Denver Complex: males go through Denver Reception and Diagnostic Center, females go through Denver Women's Correctional Facility, and intake averages three to six weeks according to CDOC.
The official CDOC facilities page shows the state-prison and campus structure behind that statewide system.
That facilities source is different from county jail rosters, which are organized locally through sheriffs and detention agencies.
Use CDOC Inmate Population for the state-prison deep dive, including the CDOC inmate locator, population figures, intake, parole, release, and records requests.
How to Search the Colorado Inmate Population
Search the Colorado inmate population by choosing the correct records owner first. The wrong search system can return no result even when the person is in custody somewhere else.
For sentenced state prisoners, the official search form is the CDOC Offender Search.
The visible DOCNO and name fields make CDOC the correct search path only after the custody record belongs to the state-prison system.
- If the person is serving a Colorado state-prison sentence, search the CDOC Offender Search.
- If the person was recently arrested or is pretrial, identify the county and use the County Directory.
- If the person is in a federal case or federal prison, search the BOP Inmate Locator.
- If immigration detention is suspected, use ICE ODLS.
- For custody notifications where available, use Colorado VINELink.
Find an Inmate by County
The county jail roster is the right tool for most recent arrests. Colorado county research also shows regional-housing patterns where smaller counties may house detainees in another county, including examples such as Cheyenne to Prowers, Dolores to Montezuma, Hinsdale to Gunnison, Kiowa to Bent, Mineral or Saguache to Rio Grande, Ouray to Montrose, San Juan to La Plata, and Yuma to Washington County. Start with the county connected to the arrest or case, then follow the local housing route shown on that county page.
That local routing is part of the statewide Colorado inmate population picture because a county without a full public jail roster may still have a sheriff records office, a phone route, a VINE notification path, or a housing agreement with another county. A Denver booking, a Weld jail record, a Mesa inmate record, and a San Juan regional-housing question can all require different official sources. The Colorado County Directory keeps those local paths separate from CDOC, BOP, ICE, and court systems.
County Jail vs. State Prison: Where to Look
County jail and state prison records answer different questions. County jail records show local custody, booking, release, bond, and jail-created records. CDOC records show state-prison custody and related CDOC status after a state sentence or transfer into the prison system.
| County Jail | State Prison / CDOC | |
|---|---|---|
| Who is held | Recent arrests, pretrial detainees, local sentences, warrants, local holds | People sentenced to Colorado Department of Corrections custody |
| Run by | County sheriff or local detention agency | Colorado Department of Corrections |
| Where to look | County jail roster, booking report, phone route, or VINELink | CDOC Offender Search |
| Coverage | One county or local agency at a time | Statewide CDOC custody |
After Sentencing in Colorado
The Colorado inmate population changes systems when a court sentence moves a person from local custody to the Colorado Department of Corrections. The county jail may still show the original booking, bond history, release to DOC, or transport event, but long-term custody questions shift to CDOC after intake begins. CDOC says every inmate goes through intake and classification at the Denver Complex. Male offenders go through Denver Reception and Diagnostic Center, while female offenders go through Denver Women's Correctional Facility. The process includes criminal history, education, program needs, fingerprints, photographs, DNA collection where required, and medical, mental-health, and dental evaluation. CDOC says average intake and classification takes three to six weeks.
This intake period explains a common search problem. A person can be out of the county jail's active roster but not yet settled at a long-term prison. That does not mean the Colorado inmate population record disappeared. It may mean the record moved from a sheriff roster to CDOC intake, or that the public CDOC result has not caught up with the transfer. After classification, CDOC assigns a facility based on custody issues, program needs, and bed space. CDOC also says it cannot accommodate requests for a particular facility or geographic area.
- Intake
- The first CDOC processing stage after a state-prison sentence, before long-term placement is final.
- Classification
- The review of custody level, health, program needs, risk factors, and placement concerns.
- Detainer
- A hold or notice from another authority that may affect release or transfer.
State and Federal Inmate Search
The CDOC locator covers sentenced Colorado state prisoners and related CDOC statuses. BOP's locator covers federal inmates incarcerated from 1982 to the present and can search by BOP Register, DCDC, FBI, or INS number, or by name fields. ICE ODLS applies to people in ICE civil immigration custody, including Aurora Contract Detention Facility contexts. VINELink is a public custody-status and victim notification layer where agencies participate, not a full booking archive or court docket.
Federal custody uses the national BOP Inmate Locator, not CDOC or a Colorado county jail roster.
This screenshot supports the federal branch of the statewide search path, especially for FCI Englewood and the Florence federal complex.
For release and transfer notifications where agencies participate, Colorado uses Colorado VINELink.
VINELink is useful as a notification layer, but it does not replace the official jail, CDOC, BOP, ICE, or court record source.
Colorado Detention Facilities
Colorado holds people across county jails, CDOC prisons, federal facilities, ICE detention settings, work-release or community corrections facilities, and DYS youth centers. The statewide facility directory is alphabetized and de-duplicated from county facility maps plus statewide gap research for youth facilities not covered by a county folder.
Court events after a jail arrest are searched separately through the Colorado Judicial Branch docket search.
That court portal belongs on the statewide map because it answers case-schedule questions that jail and prison locators do not.
Colorado Inmate Population FAQ
How big is the Colorado inmate population?
The best current statewide prison figure in the research is CDOC's January 31, 2026 report: 16,535 grand-total ADP populated beds against 16,961 operational capacity, plus 2,026 external or non-prison inmates reported separately. The research does not provide one supported statewide county-jail total.
How do I find which county jail holds an inmate?
Use the county tied to the arrest, warrant, case, or last known custody location, then open that county from the Colorado County Directory. Some rural counties house detainees in another county, so follow the local route shown by the county page when a direct roster is not available.
What if one search has no result?
A no-result in CDOC does not prove the person is not in custody. They may still be in county jail, federal custody, ICE custody, youth custody, newly transferred, released, or under a restricted record. Search by system rather than assuming one database covers everything.
