The Arapahoe County Inmate Population
The adult Arapahoe County inmate population is centered at the Arapahoe County Sheriff's Office Detention Facility in Centennial. The sheriff's detention page describes the jail as the county facility for booking, housing, release, court transport, inmate services, visitation, mail, bonds, accounts, and alternative sentencing. Aurora adds a separate city holding path for some municipal arrests, and Marvin W. Foote Youth Services Center adds a restricted youth detention path. Those three facilities are physically or operationally relevant to Arapahoe custody, but they are not searched through one public roster.
The latest located official numbers do not come from a live jail dashboard. They come from ACSO detention pages, ACSO annual reports, and state legislative jail surveys. That matters because Arapahoe County jail population data can describe different things: daily population, average daily population, bed capacity, annual intakes, bookings, releases, program counts, or costs. A jail booking total is not the same as the number of people in custody on a given day.
Arapahoe County Inmate Population Statistics
The strongest current public capacity figure comes from the ACSO Detention Services Bureau page, which says the facility accommodates approximately 1,400 inmates after expansion and remodeling. The most recent extracted average daily population figure in the research is from the ACSO 2021 Annual Report, which put the COVID-era average around 701. Older state surveys listed higher population counts before the pandemic years.
| Measure | Figure | Source and Year |
|---|---|---|
| Current ACSO facility capacity | Approximately 1,400 inmates | ACSO Detention Services Bureau, captured June 1, 2026 |
| 2017 reported capacity | 1,458 | Colorado Legislative Council / CCI county jail survey |
| 2017 daily population | 1,009 | Colorado Legislative Council / CCI county jail survey |
| 2020 bookings | 7,673 | ACSO 2020 Annual Report |
| 2021 bookings | 8,083 | ACSO 2021 Annual Report |
| Annual intakes statement | Average 17,000 inmates annually | ACSO facility history page |
| Incarceration rate | Not stated in located research | No Census-based calculation source added |
Arapahoe County Inmate Population Trends
The available trend line shows a jail population above 1,000 before the pandemic years, then a sharp drop in 2020 and 2021. ACSO annual-report material ties those lower counts to COVID-era operating conditions. The research did not locate a reliable extracted official dashboard for 2023 through 2026 daily population, so the table should be read as the latest located official annual trend, not a live count.
| Year | ADP / Daily Population | Notes |
|---|---|---|
| 2017 | 1,009 / 1,022.0 | Legislative Council table showed 1,009; later jail survey report showed CY 2017 ADP of 1,022.0. |
| 2018 | 1,073 | ACSO annual-report trend table. |
| 2019 | 1,082 | ACSO annual-report trend table. |
| 2020 | 730 | COVID-era population drop noted in ACSO annual reporting. |
| 2021 | 701 | ACSO 2021 report says average inmate population was around 700 due to COVID. |
The facility history statement that ACSO receives an average of 17,000 inmates annually is not the same measure as the 2020 or 2021 booking counts. Use it as a long-run throughput statement from the facility page, while using annual reports for year-specific bookings and releases.
Arapahoe County Inmate Population Makeup
ACSO public pages do not publish a detailed demographic table by race, ethnicity, age, sex, or pretrial/sentenced status in the located source set. What the research does support is a custody-function description. The county jail accommodates adult pretrial detainees, people serving county jail sentences, people awaiting transport, people remanded by court, and some alternative-sentencing participants tied to the jail. Court Services, Detention Operations, and Detention Administration all appear in ACSO annual-report descriptions of how the population moves through the system.
- Adult jail custody includes pretrial detainees and sentenced county-jail inmates.
- Aurora municipal holds can involve a 72-hour city detention path before release, court, or transfer.
- Youth detention at Marvin W. Foote is restricted and not an adult public roster category.
- State prison custody begins when a sentenced prisoner moves into CDOC systems.
- Federal or ICE custody uses separate federal locators and may not appear in ACSO records.
Arapahoe County Jail Capacity
The modern detention facility opened in 1987 with 404 bed spaces and 299,241 square feet. ACSO describes later expansion beginning in 1999, with added housing units occupied in late 2001 and early 2002. With later expansion and remodeling, the facility now accommodates approximately 1,400 inmates. The 2017 Colorado Legislative Council survey listed Arapahoe at 1,458 capacity and 1,009 daily population, which placed the reported population below that survey capacity.
The research did not find an official DOJ consent decree, county-posted jail litigation summary, or current overcrowding dashboard specific to Arapahoe. Recent official local-color items instead focused on facility operations and improvements, including ACSO accreditation, a 2020 body-scanner addition, a 2021 records portal implementation, and a county news item about commissioners touring new kitchen and laundry facilities tied to an 18,000-square-foot expansion.
Laws Governing Arapahoe Inmate Data
Arapahoe County inmate population and lookup access sit under several Colorado record laws and custody rules. The jail roster is a sheriff custody tool. Court records are a Judicial Branch matter. Criminal justice records are handled under CCJRA rather than ordinary CORA practice. Bond rights and jail daily-record requirements add more context for the data that appears after an arrest.
Key statutes and rules:
CORA, C.R.S. 24-72-201 to 206 governs general Colorado public records, with ordinary production timelines and lawful exceptions.
CCJRA, C.R.S. 24-72-301 to 309 governs criminal justice records such as law-enforcement and correctional records.
C.R.S. 17-26-118 requires jail keepers to maintain daily records with specified jail data.
C.R.S. 16-4-102 addresses bond rights before conviction and appears in ACSO's charge and bond context.
Search Arapahoe County Inmate Population
The current adult county-jail search is the ACSO Inmate Lookup, Charges and Bonds app. It covers current sheriff detention custody and bond or court fields that ACSO posts through the public lookup. It is not a mugshot gallery, a released-inmate archive, a court-copy system, or a statewide criminal-history search. The same app is embedded on the sheriff's inmate charges and bonds page.
- Open the ACSO charge and bond lookup.
- Enter the last name or first part of the last name. Add first or middle name for common names.
- Click the matching result row when several names appear.
- Read the full charge profile, including total bond, booking number, charge rows, docket fields, and court date if posted.
- If no record appears, call 720-874-3500 or check Aurora, CDOC, BOP, ICE, or records-request channels.
Arapahoe County Inmate Lookup Fields
The ACSO lookup is simple. It asks for first, middle, and last name, with last name required. No public date-of-birth field, facility filter, booking-date filter, or released-inmate tab was found in the inspected public app.
| Field | Type | Required | Notes |
|---|---|---|---|
| First name | Text | No | Optional narrowing field. |
| Middle name | Text | No | Optional narrowing field. |
| Last name | Text | Yes | Blank search triggers the app's last-name validation warning. |
The official search form is shown in the captured roster image below.
The form design supports fast current-custody lookup but makes accurate name matching important.
Arapahoe County Inmate Records
A current profile can show more than one charge row. Read every row, not only the first line. A person may have different dockets, bond types, or court dates on the same profile. Some fields in the official response may be blank, and the public app did not show mugshots, housing unit details, public date of birth, height, weight, or race in the inspected record.
| Field | What It Means |
|---|---|
| Inmate ID | Local ACSO jail identifier, not the same as a booking number. |
| Booking number | Booking-specific number shown after opening the charge view. |
| Total bond | Combined bond amount; PR bonds may not count toward the total. |
| Charge/class | Offense and class such as felony or misdemeanor. |
| Docket/disposition | Court or case context, still subject to Judicial Branch confirmation. |
| Court date/location | Hearing date, time, or division when posted. |
County Jail vs State Prison
Readers often search the wrong system after sentencing. The Arapahoe County jail roster covers local detention custody, including pretrial and county-jail stages. The CDOC offender search covers sentenced state prisoners and uses DOC number, name, gender, and a captcha/math control. A person sentenced to DOC may remain in county jail temporarily before transport or intake, so there can be a lag between sentencing and state locator visibility.
| County Jail | State Prison | |
|---|---|---|
| Primary agency | Arapahoe County Sheriff's Office | Colorado Department of Corrections |
| Common stage | Arrest, booking, pretrial, short sentence, court remand | Sentenced state-prison custody |
| Lookup | ACSO charge and bond app | CDOC offender search |
| Local facility | ACSO Detention Facility in Centennial | No CDOC prison found in official Arapahoe County facility checks |
State and Federal Inmate Search
No CDOC prison, BOP prison, ICE detention center, or USMS-operated facility was confirmed inside Arapahoe County in the research. Those systems still matter as fallback channels. Use CDOC for sentenced Colorado prisoners. Use BOP for federal sentenced inmates from 1982 forward. Use ICE ODLS for immigration detainees currently or recently in ICE custody. Use VINELink for custody notification where Colorado or local agency coverage is active.
Federal pretrial defendants may not appear in BOP because the U.S. Marshals Service can hold people in local or contract facilities before sentence. ICE searches can also fail when biographical information is incomplete, the detention is very recent, or public ODLS criteria do not match. Those limits are system limits, not proof that no custody exists.
Arapahoe County Detention Facilities
The facility map resolves three pages for this project. The primary county jail comes first, then the Aurora city holding facility, then the CDHS youth center. Each has a different lookup path and public-record boundary.
- Arapahoe County Sheriff's Office Detention Facility - adult county jail for pretrial, sentenced county-jail, booking, bond, release, court transport, and inmate services.
- Aurora Detention Center - city 72-hour adult municipal holding facility for Aurora Police, Aurora City Marshals, court, bond, release, or transfer situations.
- Marvin W. Foote Youth Services Center - secure CDHS youth detention center for detained youth, with restricted records and authorized-party contact paths.
Arapahoe County Inmate Population FAQ
How large is the Arapahoe County inmate population?
The latest extracted official ADP in the research is 701 from the ACSO 2021 Annual Report. ACSO's live detention page states the jail accommodates approximately 1,400 inmates. No official live daily dashboard was located.
How do I search the Arapahoe County inmate population?
Use the ACSO charge and bond lookup for current adult county-jail custody. Search by last name or partial last name, then open the result row for booking, charge, bond, and court fields.
Why is an Aurora arrest missing from ACSO?
Aurora operates a 72-hour adult holding facility. A recent Aurora detainee may still be in city custody, released, in municipal court processing, or transferred to Arapahoe or Adams County.
Does the Arapahoe roster show mugshots?
The inspected ACSO public charge and bond app did not display booking photos. Public booking-photo requests route through ACSO records with a Colorado pecuniary-gain attestation.
Where are sentenced inmates searched?
Search sentenced Colorado prisoners in CDOC, not the county jail roster. Federal sentenced custody uses BOP, and immigration custody uses ICE ODLS.
Can youth at Marvin W. Foote be searched online?
No public adult-style roster was located for Marvin W. Foote. Youth custody records are restricted, and authorized family, guardian, attorney, or DYS channels should be used.
