Union County Inmate Population
The key Union County inmate population fact is the June 2021 transfer of full correctional housing to Essex County. Union County announced that the traditional jail operation was transferred effective 11:59 p.m. on June 30, 2021. The Elizabeth correctional site remained open as an intake hub and temporary detention facility, while incarcerated people from Union County were to be housed at the Essex County Correctional Facility. Union County's visiting instructions also name Hudson County as a jail where Union inmates may be located. That means a current custody search can move from Union's sheriff lookup to Essex, Hudson, VINE, or a court record depending on timing.
The Union County Sheriff Office Division of Corrections is still the local corrections contact for intake, classification, and the official lookup path. Its corrections page lists Captain Anthony Davis as officer in charge, a public corrections number of 908-558-2600, and the 15 Elizabethtown Plaza address. The main Union County Sheriff Office is nearby at 10 Elizabethtown Plaza and lists Sheriff Peter D. Corvelli Jr. and 908-527-4450. Those two contacts matter because a person may be in local intake before the online roster or the receiving jail shows a clean record.
This split also changes how a public record should be read. A Union lookup result can help identify a booking or selected offender information, but it may not show the current housing unit after transfer. A person can be in Union intake early in the day, appear in a regional jail process later, and then have formal charge information appear in a court portal after prosecutor review. The most accurate Union County inmate population search follows the custody stage instead of assuming that every local arrest remains in one Elizabeth jail.
Union County Inmate Population Statistics
Union County published several figures around the 2021 corrections transfer. The county said the jail population had been more than 1,000 about a decade before the transfer and had fallen to 345 at the beginning of 2021. A separate BJS-derived correctional population table reported a 2013 Union County Jail average daily population of 795. The Essex facility that now houses many Union County detainees has a documented rated capacity of 2,434 and a 2022 assessment describing a day-to-day population of about 2,000 to 2,200.

Union County Inmate Population Trends
The Union County inmate population trend is a long decline followed by a structural change in where people are held. The county described a nearly 67 percent fall in population over ten years before the 2021 transfer. The public impact is direct: a person arrested in Union County can still pass through the Elizabeth intake hub, yet the daily housing rules, mail, visitation, bail counter, and some confirmation calls may come from Essex or Hudson.
| Year or Period | Population Figure | Notes |
|---|---|---|
| About a decade before 2021 | More than 1,000 | County cited the earlier full-jail population when explaining the transfer. |
| 2013 | 795 ADP | BJS-derived county correctional population table. |
| Beginning of 2021 | 345 | County cited the lower count before the Essex transfer. |
| After June 30, 2021 | Housing shifted | Elizabeth remained intake and temporary detention while Essex became the main housing jail. |
The same release said the transfer was expected to save more than $103 million over five years. It also said the jail workforce had 243 employees before the transfer and about 53 corrections officers and civilians remaining for hub operations. Those staffing figures help explain why the Union County inmate population should not be described as a normal full jail housed in Elizabeth.
The public data also leaves a current measurement gap. The research did not locate an official dashboard that reports a daily Union-only count after the transfer to Essex and Hudson. For that reason, the clearest current Union County inmate population description is operational: Union handles intake and lookup contact, Essex is the main contracted jail named in the transfer, Hudson is named by Union's visiting instructions, and state or federal custody must be counted through separate systems.
Union County Jail Capacity
Current Union County capacity is best framed by function rather than a public bed count. Research did not locate an official present bed count for the Elizabeth intake hub, and the page should not invent one. The county's own description says the Elizabeth facility performs intake, processing, and temporary detention. For many active detainees, practical capacity and housing questions belong to Essex or Hudson after transfer.
Essex is the documented large facility in the Union County custody chain. The 2022 Essex County Correctional Facility assessment gives a 2,434 rated capacity and says the average day-to-day population was about 2,000 to 2,200. Hudson County Adult Correctional Center is also named by Union County for inmate location calls, but the research did not confirm an official public capacity figure for Hudson.
Union County Inmate Record Laws
New Jersey law shapes what can be seen about the Union County inmate population. OPRA makes many government records open unless an exemption applies, while criminal-investigation records and court restrictions can limit release. County jail operations are also governed by state administrative standards for adult county correctional facilities. These rules do not make every jail detail public, but they do explain why arrest, charge, bail, and booking information may be available through a roster, court portal, or written request.
Key Statutes:
N.J.S.A. 47:1A-1 says government records are generally open for inspection or copying unless a legal limit applies.
N.J.S.A. 47:1A-3(b) requires key arrest information, charge text, arresting agency, and bail circumstances to be available unless protected.
N.J.S.A. 47:1A-5 covers written OPRA requests, copy access, redactions, and the general seven-business-day response rule.
N.J.A.C. 10A:31 sets adult county jail standards for records, security, health services, inmate rights, and operations.
N.J.S.A. 2A:162-17 requires a pretrial release decision without needless delay and generally within 48 hours after jail commitment for eligible defendants.
Union County State Prison Population
Sentenced state-prison custody is not part of the Union County jail roster. A person from Union County who receives a state prison term moves to the New Jersey Department of Corrections offender search. NJDOC says its offender search is updated biweekly and that phone inquiries about offender information cannot be honored. The department also says records are removed from the public web page one year after completion of the custodial term, maximum sentence date, or mandatory parole supervision date, except certain CSL and PSL cases.
NJDOC reported 12,856 people in statewide custody as of January 1, 2025. No state prison was identified as physically located in Union County for the facility map. Nearby prison names can be misleading, so the statewide locator is the proper tool for sentenced people rather than the Union sheriff lookup.
Search Union County Inmate Population
The official Union County inmate search begins at the Sheriff's inmate look up disclaimer. That page links to the roster after the user agrees to the terms. The disclaimer says the lookup exists for public safety and community access to selected offender information in the spirit of OPRA. It also says the information is updated daily, not in real time, and may change quickly.
The official Union County inmate lookup disclaimer page is shown in this captured research image.
The disclaimer is important because the roster may include selected information only, and it warns that released or paroled records are not updated after custody ends.
- Open the Union County Sheriff inmate look up disclaimer.
- Read the purpose, note, and warning language before entering the portal.
- Select the agreement link to reach the official roster endpoint.
- Search with the fields the portal presents, but do not assume a no-result means no custody.
- Call Union Corrections at 908-558-2600 or the Sheriff at 908-527-4450 if the arrest is recent.
- Call Essex at 973-274-3001 or Hudson at 201-395-5600 when the person may have been transferred.
- Use NJDOC, BOP, ICE ODLS, or VINE when the custody type points outside the county jail chain.
Union County Roster Fields
The live Union portal could not be inspected from the research environment because the endpoint timed out. That limits field claims. The safe source-backed statement is that the roster uses an agreement screen and provides selected offender information. Exact profile labels should be confirmed inside the active portal or through the Classification Unit.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Disclaimer acceptance | Link or button | Yes | The user must accept terms from the official disclaimer. |
| Name search | Text | Not confirmed | Likely search path, but exact labels were not visible. |
| Booking or offender identifier | Text | Not confirmed | Do not rely on this field unless it appears in the portal. |
| Search or submit | Button | Not confirmed | Portal button labels were not available during research. |
| Reset or clear | Button | Not confirmed | Clear functions were not confirmed. |
Union County Inmate Record Details
Union County's public materials do not expose a verified sample profile, so the record should be read by category. A result can help identify a person and custody context, but the disclaimer controls: some people may be excluded, work release or furlough status may not be reflected, and released records are not updated after the person leaves custody. Formal charges should be checked through New Jersey court systems because booking language can differ from prosecutor-filed charges.
| Field or Topic | How to Read It |
|---|---|
| Name | Core identifier, but use age, charge context, and facility when available to avoid mistaken identity. |
| Custody status | May lag, especially after release, parole, transfer, work release, furlough, or residential placement. |
| Facility or location | Confirm by phone because Union inmates may be at Essex or Hudson after intake. |
| Charges | Use court portals for formal complaint, accusation, indictment, and disposition details. |
| Mugshot | Public display was not verified; request a booking photo under OPRA if it is not visible and not restricted. |
| Redactions | Juvenile, sealed, expunged, victim, medical, personal identifier, and investigatory material may be withheld. |
County Jail vs State Prison
Union County jail records and state prison records answer different questions. County custody covers arrest intake, booking, pretrial detention, temporary local holds, and short-term county-jail status. State prison custody follows a sentence to NJDOC. Federal criminal custody and ICE civil detention use separate national systems. Mixing these systems is the most common reason a search fails.
| Custody Type | Where to Look | What It Covers |
|---|---|---|
| Union County intake or pretrial custody | Union sheriff lookup, Union Corrections phone, Essex/Hudson calls | New arrests, booking, transfer, local jail housing |
| Sentenced state prison | NJDOC offender search | State prison terms, updated biweekly |
| Federal prison | BOP inmate locator | Federal inmates from 1982 to present |
| Immigration detention | ICE Online Detainee Locator System | ICE civil detainees, including possible Elizabeth detention housing |
| Custody notifications | New Jersey VINE | Notification and custody-status registration where available |
Union County Detention Facilities
The Union County inmate population is served by four important custody points. The first is the Elizabeth intake hub. Essex and Hudson are regional county jail destinations named by Union County for housing or inmate-location calls. The Elizabeth Contract Detention Facility is separate and handles ICE civil immigration detention, not ordinary Union County criminal cases.
- Union County Jail / Division of Corrections Intake Hub handles intake, temporary detention, classification, and lookup questions at the local corrections address.
- Essex County Correctional Facility houses many Union County incarcerated people under the 2021 intercounty jail-services arrangement.
- Hudson County Adult Correctional Center is also named by Union County for inmate-location calls and may house Union detainees.
- Elizabeth Contract Detention Facility / Elizabeth Detention Center is an ICE contract facility for civil immigration detainees.
Union County Inmate Population FAQ
How big is the Union County inmate population? Union County cited 345 people at the beginning of 2021 after a long decline from more than 1,000 about a decade earlier. Since June 30, 2021, routine housing has been transferred to Essex, with Union continuing local intake.
Where should a current Union County inmate search start? Start with the sheriff's inmate look up disclaimer and linked portal. If the search fails or the arrest is recent, call Union Corrections, then Essex or Hudson using the numbers Union provides.
Can a released inmate be looked up? The Union disclaimer says released or paroled records are not updated after custody ends. For older booking records, use a precise Union County Sheriff OPRA request and court portals for charge outcomes.
Does Union County use VINE? New Jersey VINE is available for custody-status notifications. It is an added alert tool, not a full substitute for the sheriff lookup or jail phone confirmation.
Is the sheriff app a roster? The Union County Sheriff's Office app and Explore Union County app are public-safety and county-service tools. Research did not show that either replaces the official inmate lookup.
