The Jefferson County Inmate Population
The Jefferson County inmate population is centered on the Jefferson County Detention Facility in Golden. That jail is run by the Jefferson County Sheriff's Office Detention Services Division and holds local arrestees, pretrial detainees, people serving county jail sentences, people waiting for court, work-release eligible inmates before transfer, and some outside-agency holds when accepted. The county jail count is not the same as the state prison count, and it is not the same as the federal population at FCI Englewood.
The strongest current local operating numbers come from Jefferson County's 2024 Annual Comprehensive Financial Report. It lists a 2024 average daily inmate population of 872, annual sheriff bookings of 15,942, and an average stay of 25.0 days. Those figures describe county sheriff operations, not every person confined inside Jefferson County's borders. FCI Englewood is a separate Bureau of Prisons facility in Littleton, and its federal count is searched through BOP, not through the county jail roster.
Jefferson County Inmate Population Statistics
Jefferson County publishes useful jail operating indicators through county financial reports, while JCSO publishes facility facts on the jail page and strategic plan. The current jail page describes an approximately 1,300-inmate capacity and a 388,000-square-foot facility. The JCSO strategic plan uses a separate detention-capacity figure of 1,447, and the 2020 annual report listed 1,392 fixed beds. Those figures should be read as source and date differences, not one blended capacity number.
| Measure | Figure | Source / Year |
|---|---|---|
| Average daily inmate population | 872 | Jefferson County 2024 ACFR |
| Annual sheriff bookings | 15,942 | Jefferson County 2024 ACFR |
| Average length of stay | 25.0 days | Jefferson County 2024 ACFR |
| Current jail-page capacity | Approximately 1,300 inmates | JCSO jail page, accessed June 2026 |
| Strategic-plan detention capacity | 1,447 | JCSO strategic plan |
| FCI Englewood federal population | 930 total inmates | BOP population table, last updated October 9, 2025 |
Jefferson County Inmate Population Trends
The county data shows a lower average daily jail population in 2024 than in 2022 and 2023, even while bookings stayed far above the 2020 and 2021 pandemic-era levels. The 2024 ACFR lists 872 average daily inmates, down from 956 in 2023 and 990 in 2022. Average stay also fell from 31.0 days in 2022 to 27.0 in 2023 and 25.0 in 2024. That mix suggests faster turnover, not simply fewer jail admissions.
The pre-COVID comparison is sharper. The 2020 JCSO annual report says bookings fell from 25,173 in 2019 to 11,714 in 2020, a 53% drop, while the detention facility also used booking standards, population limits, video court, and testing protocols. Vera's county trend data adds broader context, including pretrial and sentenced custody splits, but its rated-capacity series does not match current JCSO capacity definitions. Use Vera for trend context, not for the current facility capacity.
| Year | Average Daily Population | Annual Bookings | Average Stay |
|---|---|---|---|
| 2024 | 872 | 15,942 | 25.0 days |
| 2023 | 956 | 16,024 | 27.0 days |
| 2022 | 990 | 13,050 | 31.0 days |
| 2021 | 817 | 12,375 | 30.0 days |
| 2020 | 765 | 11,714 | 31.0 days |
| 2019 | 1,302 | 25,173 | 21.9 days |
Who Makes Up Jefferson County Jail Custody
Official current jail demographics by race, age, sex, and charge level were not located in public JCSO sources. The county population can be described from Census QuickFacts, but those demographics do not prove the makeup of the jail. For jail composition, the most useful sourced split is Vera's trend series. Vera reported a 2024 total jail population of 936.5, with 712.5 in pretrial custody and 224 sentenced custody. That is trend data, not a live roster count.
- Pretrial custody: Vera's 2024 trend row shows most Jefferson County jail custody was pretrial.
- Sentenced custody: County jail sentences and short local commitments remain in the jail until release or transfer.
- State prison custody: A person sentenced to Colorado prison transfers to CDOC and leaves the county roster.
- Federal custody: FCI Englewood's population is federal and is tracked through BOP.
Jefferson County Jail Capacity
JCSO's current jail page lists the Jefferson County Detention Facility as one of Colorado's largest county jails, with approximately 1,300-inmate capacity, medical and mental-health units, intake and release areas, courtrooms, and multiple housing units for different classifications. The facility opened in 1986 and expanded in 1999. The accreditation page says detention operations hold ACA and NCCHC accreditation, with a 100% mandatory standards compliance result in the October 2023 detention audit.
A simple comparison of the 2024 ADP of 872 to the current jail-page capacity of about 1,300 suggests the annual average was below that published figure. That does not mean every housing unit had open usable space. Operational capacity can be affected by classification, medical housing, mental-health placement, staffing, court holds, special housing, and source definitions. The JCSO strategic plan also lists a Detentions Division budget of $63.3 million and 394 detentions FTE, which shows that staffing is part of jail capacity in practice.
Laws Governing Jefferson County Jail Data
Colorado law separates ordinary public records from criminal justice records. For the Jefferson County inmate population, the key local route is the sheriff's current-custody lookup for current inmates and the JCSO Records/NextRequest process for former inmate, booking, release, and detention records. Statutes matter because they explain why daily jail data, bond status, and criminal justice records may be public while juvenile, sealed, active-investigation, victim, and protected records can be withheld or redacted.
Key Statutes:
C.R.S. 17-26-118 requires jail keepers to maintain daily records and defines jail-population measures such as average daily population, operational capacity, hold, sentenced inmate, and unsentenced inmate.
C.R.S. 24-72-301 et seq. is the Colorado Criminal Justice Records Act, the framework JCSO cites for criminal justice records requests.
C.R.S. 16-4-102 governs money bond rights and says booking fees or other debts do not have to be paid to secure release on a money bond.
Colorado Jail Standards oversight sets statewide jail-standards compliance expectations, with the final report pointing to a July 1, 2026 compliance date.
Jefferson County and State Prison Custody
No current Colorado Department of Corrections prison was confirmed as operating inside Jefferson County. The former Colorado Correctional Center at Camp George West appears in historical references as closed. CDOC still matters because a Jefferson County defendant who receives a state-prison sentence leaves the local jail population after transfer and is searched through the CDOC Offender Search, not the JCSO current inmate lookup.
That transfer can create a short database gap. A person may no longer appear as a current Jefferson County inmate once release or transfer paperwork is complete, but may not yet have a fully visible state-prison locator record if intake and classification are still underway. For release notifications, JCSO points victims to Colorado VINELink and also provides the jail information line for custody questions.
How to Search Jefferson County Inmates
The official county search is the JCSO Inmate Lookup. It searches current inmates at the Jefferson County Detention Facility only. JCSO says former inmate information must be obtained through the Records Unit, inmates under 18 are not searchable, and the information updates every 15 minutes but can change quickly. The lookup is useful for current custody, bond status, and jail routing, but it is not a court-file database.
Start with a name or booking date. If no record appears, check spelling and aliases, then use the jail information phone line because JCSO says phone staff can search by name, date of birth, or booking date. If the person was sentenced to state prison, search CDOC. If the person is federal, search BOP. If immigration custody is possible, use ICE ODLS.
- Open the official JCSO Inmate Lookup page.
- Search by last name, first name, or booking date.
- Confirm that the result is current Jefferson County jail custody.
- Call 303-271-5444 if the roster fails or the booking is very recent.
- Use CDOC, BOP, ICE ODLS, or Records/NextRequest when the county roster is the wrong system.
Jefferson County Roster Search Fields
The captured JCSO search page exposes a small set of search inputs. It does not publish wildcard rules, and the research pass did not expose a live inmate profile. Because of that, the roster should be treated as a current-custody locator first. Do not treat a matching name as legal proof of identity; JCSO warns that true identity can only be confirmed by fingerprint comparison.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | Unspecified | JCSO says enter a last name to search current inmates. |
| First Name | Text | Unspecified | May be used to narrow or search, based on the page notice. |
| Booking Date | Date/text input | Unspecified | Public text did not publish the date format. |
| Search | Button | n/a | Submits the current-custody lookup. |
The official inmate lookup screenshot shows the current-custody search fields and the 15-minute update notice.
That source is the right starting point for someone in local jail custody, but former inmates, sealed matters, juveniles, state prisoners, and federal inmates require different channels.
Past Jefferson County Inmate Records
The JCSO roster displays current inmates only. Former inmate information, booking records, release records, and other detention facility records go through JCSO Records & Reports or the NextRequest public-records portal. Records may be requested online or in person. The Records Unit phone is 303-271-5542, and records staff identify court records, statewide criminal history, sealed or expunged records, active investigation materials, juvenile records, and some dispatch records as items JCSO does not maintain or cannot release through ordinary jail-record channels.
Records fees are local and concrete. JCSO lists a $3 processing fee, the first hour of research, retrieval, and redaction free, then $40 per hour. Hardcopies, CD/DVD, flash drives, postal delivery, and large body-worn-camera requests may add costs. Former custody information is not a roster refresh problem. It is a records request problem.
What a Jefferson County Inmate Record Shows
The public page confirms the search inputs and the major warnings more clearly than it confirms a full inmate-profile layout. It says the tool covers current Jefferson County Detention Facility inmates, excludes inmates under 18, updates every 15 minutes, and should not be relied on for legal action. The research did not confirm whether mugshots, charges, housing unit, or booking-number fields display in a public profile.
| Confirmed Field or Notice | What It Shows |
|---|---|
| Last Name | Search input for current jail custody. |
| First Name | Search input for current jail custody. |
| Booking Date | Search input for a known booking day. |
| Current-custody scope | The lookup only displays current inmates. |
| Juvenile exclusion | People under 18 are not searchable. |
| Update warning | Information updates every 15 minutes and can change quickly. |
County Jail vs State Prison Search
Jefferson County jail custody is for local arrest, pretrial detention, short local sentences, court holds, booking, bond, and release. Colorado prison custody is a state sentence system. A person can move from the county jail to CDOC after sentencing, but the databases do not merge. Federal and immigration custody are separate again.
| County Jail | State Prison | Federal Prison | |
|---|---|---|---|
| Run By | Jefferson County Sheriff's Office | Colorado Department of Corrections | Federal Bureau of Prisons |
| Who Is Held | Pretrial and local jail custody | State-sentenced prisoners | Federal sentenced inmates and some detainees |
| Where to Look | JCSO Inmate Lookup | CDOC Offender Search | BOP Inmate Locator |
| Jefferson County Example | Jefferson County Detention Facility | No current CDOC prison confirmed in county | FCI Englewood |
State and Federal Inmate Search
Use CDOC Offender Search for Colorado state-prison sentences, BOP Inmate Locator for federal custody from 1982 to the present, and ICE ODLS for immigration detention. BOP's sample result fields include name, register number, age, race, sex, release date, and location. ICE requires an A-number and country of birth, or exact biographical information. VINELink is for custody and release notification, not a substitute for the roster.
Jefferson County Detention Facilities
The facility map has two current physical facilities in Jefferson County that matter to inmate lookup. They are not interchangeable. One is the county jail, and one is federal prison custody.
- Jefferson County Detention Facility - the county jail for local arrests, pretrial custody, county sentences, release, bond, visitation, records, and current JCSO roster searches.
- FCI Englewood - a Bureau of Prisons facility in Littleton for federal inmates, searched through BOP rather than the Jefferson County jail roster.
Jefferson County Inmate Population FAQ
How large is the Jefferson County inmate population?
The 2024 ACFR lists a Jefferson County average daily inmate population of 872 and 15,942 annual sheriff bookings. JCSO's current jail page lists approximately 1,300-inmate capacity. FCI Englewood's BOP population figure of 930 is separate federal custody and should not be added to the county jail ADP.
How do I search the Jefferson County inmate population?
Search current county jail custody through the JCSO Inmate Lookup. Call 303-271-5444 if the online search fails or the booking is recent. Use CDOC for state prison, BOP for federal custody, ICE ODLS for immigration detention, and JCSO Records/NextRequest for former inmate records.
Are former inmates on the Jefferson County jail roster?
No. JCSO states the online lookup displays current inmates only. Former inmate information, booking records, release records, and other detention records are requested through the Records Unit or NextRequest, subject to Colorado criminal justice records limits and fees.
