Union County Inmate Population
Union County, New Mexico has a small but unusual custody map. The local jail side centers on the Union County Detention Center, tied to the Union County Sheriff's Office. The state prison side is Northeast New Mexico Correctional Facility, an NMCD prison near Clayton. Those two facilities should not be merged when reading the Union County inmate population. A person arrested locally may begin in county custody, appear in court, and later transfer to the New Mexico Corrections Department if sentenced to prison.
Official Union County pages reviewed for this build did not publish a current jail population count, rated jail capacity, daily booking count, or public jail roster. That absence is a key local fact. For the county jail, the useful public path is the sheriff phone line, a records request, and court lookup once charges are filed. For the state prison, the useful path is the NMCD Offender Search and the prison’s own contact and visitation rules.
Union County Inmate Population Statistics
The county jail portion of the Union County inmate population is not shown in an official daily public dashboard found during research. No official Union County jail capacity, average daily population, annual bookings, or demographic split was located on the sheriff, county departments, or county site-search pages. The state prison portion has better published context because NMCD and outside correctional data sources report state-prison information.
| Measure | Figure | Source / Year |
|---|---|---|
| Union County Detention Center rated capacity | Not published in official sources located | Union County sheriff and department pages inspected in 2026 |
| Union County Detention Center current population | Not published in official sources located | No official local roster or daily count found |
| Northeast New Mexico Correctional Facility historical population | 609 prisoners | Prison Policy Initiative correctional-population data from BJS/Census source |
| Northeast New Mexico Correctional Facility physical plant | 179,624 square feet | NMCD 2021 Annual Report |
| NMCD Adult Prisons Division capacity | Just under 7,800 | NMCD 2021 Annual Report |
| NMCD 2021 daily average prison population | 5,821 | NMCD 2021 Annual Report |
Union County Custody Trends
Trend data for the Union County jail was not found in the official county materials. That means a public user cannot safely infer whether the local jail population is rising, falling, crowded, or stable from the county website alone. A future daily count, budget packet, or IPRA response may fill that gap, but the current official web record does not provide a year-by-year local jail trend.
The better trend story in Union County is the state prison. NMCD reports that the State of New Mexico took over Northeast New Mexico Correctional Facility in 2019 after it had been a private facility. Statewide prison population reports then give broader New Mexico prison counts, including the 2021 NMCD daily average and later New Mexico Sentencing Commission forecast figures.
| Year / Period | Population or Capacity Figure | Notes |
|---|---|---|
| 2012 survey date | 609 at Northeast New Mexico Detention Facility | Historical BJS/Census-source state prison figure, not county jail ADP |
| 2019 | State takeover of NENMCF | NMCD annual report states New Mexico took over operations |
| CY2021 | 5,821 NMCD daily average population | Statewide Adult Prisons Division figure |
| FY2023 | 5,333 confined individuals in NMSC profile base | State prison profile dataset after exclusions |
| FY2025 | 5,341 male prison average; 505 female average | New Mexico prison population forecast |
Union County Jail and Prison Population
The Union County inmate population is best read as two separate groups. The county jail group includes people newly arrested, held before trial, held on local warrants, serving short county-level sentences, or waiting on transfer. The state prison group includes sentenced New Mexico prisoners held by NMCD at Northeast New Mexico Correctional Facility. The same town can be involved, but the custody system, lookup tool, visitation rule, and records custodian are different.
This distinction prevents one of the most common search mistakes. A newly arrested person may not appear in NMCD because NMCD says it has no jurisdiction over county or city detention facilities. A sentenced state prisoner at the Clayton prison should not be searched through a Union County jail roster. A federal pretrial detainee or immigration detainee may involve the U.S. Marshals Service, BOP, or ICE instead.
| Custody Type | Who Runs It | Where to Check |
|---|---|---|
| Local pretrial or short county jail hold | Union County Sheriff's Office | Call the sheriff at 575-374-2583; no official online roster was found |
| Sentenced New Mexico prisoner | New Mexico Corrections Department | NMCD Offender Search or search.cd.nm.gov |
| Federal sentenced prisoner | Federal Bureau of Prisons | BOP Inmate Locator |
| Immigration detainee | U.S. Immigration and Customs Enforcement | ICE Online Detainee Locator System |
New Mexico Inmate Record Laws
New Mexico’s Inspection of Public Records Act supplies the main access framework for jail and law-enforcement records. It starts from broad public access, but law-enforcement records can still be redacted or withheld when a specific law or exception applies. That matters for Union County booking records, booking photos, incident reports, and older jail records because the county does not publish a roster that answers every question online.
Key New Mexico access rules:
NMSA 1978 Section 14-2-8(D) requires written public-record requests to identify the requester and the records sought with reasonable detail.
NMSA 1978 Section 14-2-1.2 treats law-enforcement records as public records except where law allows withholding or redaction.
NMSA 1978 Section 14-3-15.1 is referenced by Case Lookup for limits on bulk downloading court records.
For court charges, use New Mexico courts, not the jail alone. For statewide arrest or criminal-history checks, the New Mexico Department of Public Safety Law Enforcement Records Bureau is the state channel noted in the research. Courts state that they do not conduct criminal background checks or keep law-enforcement records.
Search Union County Current Inmates
No official public Union County, New Mexico jail roster or inmate-search portal was located on the county site. The official sheriff page and county departments page do not link to a jail roster, booking report, current-inmate list, inmate inquiry form, or mugshot gallery. For a current county-jail custody answer, call the Union County Sheriff's Office and have the person’s full name, date of birth if known, arrest date, and arresting agency ready.
The source pages that matter most are the Sheriff's Office page, the official sheriff staff directory, and the county departments page. Those pages show the sheriff function, but they do not create a public online roster. Search results for “Union County jail roster” often point to other states, so confirm that a result is for Union County, New Mexico before relying on it.
- Start with the official Union County Sheriff's Office contact, not a third-party page from another state.
- Call 575-374-2583 and ask whether the person is held at the Union County Detention Center.
- If the person is not held locally, ask whether release, bond, transfer, NMCD commitment, federal custody, or immigration custody applies.
- Use New Mexico Case Lookup for filed charges after arrest.
- Use NMCD, BOP, ICE, or VINELink when the sheriff points to a different custody system.
Union County Roster Search Fields
A normal jail roster table would list fields such as name, booking number, booking date, charges, bond, and release status. Union County’s official sources did not expose that kind of public form. The field inventory for the local jail is therefore a no-public-form inventory rather than a working roster search screen.
| Field Label | Type | Required | Options / Format Notes |
|---|---|---|---|
| Local jail roster search | Not available | n/a | No official public Union County, NM jail roster form located |
| Last Name | n/a | n/a | No county roster field located |
| First Name | n/a | n/a | No county roster field located |
| Booking Number | n/a | n/a | No county roster field located |
| Booking Date | n/a | n/a | No county roster field located |
| Facility | n/a | n/a | No county roster dropdown located |
For state prison searches, NMCD does publish a form. It accepts last name, first name, or offender number, uses offender-status choices, and includes reCAPTCHA. That form is for state prison, probation, and parole records. It is not a Union County jail booking search.
Union County Inmate Record Details
Because no Union County public jail profile was found, the page should not promise online mugshots, charges, bond amounts, housing pods, or court dates for a local jail profile. The more accurate approach is to split the record question into three levels: what the sheriff may confirm by phone or records request, what NMCD shows for state prisoners, and what court records show after charges are filed.
| Field | What It Shows |
|---|---|
| Name | The detained person’s legal or booking name, if confirmed by the sheriff or produced in a booking record. |
| Booking date/time | Not publicly searchable online in official Union County sources located. |
| Charges | Booking charges may differ from prosecutor-filed court charges. |
| Bond | No online county bond table was located; confirm with the jail or court. |
| Mugshot | No official Union County mugshot gallery or roster photo was located. |
| Release status | Verify by sheriff phone, VINELink if available, court docket, or records request. |
Union County State and Federal Search
NMCD is the main statewide system for sentenced New Mexico prisoners and people on probation or parole. Its public information page says Adult Prison Division data updates nightly, while Probation and Parole updates in real time. NMCD also warns that Central Office, Constituent Services, and the Records Bureau will not provide release statuses, so users should verify location and legal status with the institution or supervision office.
The BOP locator covers federal inmates from 1982 to the present and searches by register number or by name. Federal pretrial detainees may be in U.S. Marshals custody and may not appear in BOP. The ICE locator is a separate immigration-custody tool and requires JavaScript. VINELink New Mexico can help with custody notification, but it is not a full booking-record archive.
Union County Detention Facilities
The facility map has two entries. The Union County Detention Center is the local jail facility tied to the sheriff and should be used for current local custody questions. Northeast New Mexico Correctional Facility is a state prison in Union County and should be searched through NMCD. Both names can appear in Clayton-related searches, but they serve different people.
- Union County Detention Center holds local pretrial detainees and people serving county-level sentences, with custody confirmation through the sheriff.
- Northeast New Mexico Correctional Facility holds sentenced New Mexico state prisoners under NMCD rules.
Union County Official Sources
The official Union County Sheriff's Office page is the first local source for county jail questions, and the screenshot below reflects that lean contact-focused page rather than an online roster.
The lack of a roster link on that source is why the Union County inmate population search starts with direct sheriff contact for local jail custody.
The NMCD Offender Search form is the separate state-prison channel for people committed to New Mexico Corrections Department custody.
Use the NMCD form only after the person is in state prison, probation, or parole records, not for a fresh Union County jail booking.
