Union County Inmate Population
Union County's inmate population is best read in layers. The local jail is the county-level facility for recent arrests, pretrial detention, short county sentences, court commitments, and local holds. The Pennsylvania Department of Corrections 2025 county prison inspection schedule lists Union County Jail with 37 beds. That is the only official local capacity figure found in the research, and no official daily local jail population dashboard or average daily population report was located on county or PADOC public pages.
The headcount physically inside Union County is much larger because the county also contains four Federal Bureau of Prisons facilities. BOP public endpoints captured in June 2026 reported 1,115 inmates at FCI Lewisburg, 1,014 at FCI Allenwood Low, 1,078 at FCI Allenwood Medium, and 373 at USP Allenwood. Those federal inmates are not counted as the local jail roster, and they are not normally Union County arrestees. They belong in the BOP locator, while a person arrested in Lewisburg, Mifflinburg, or a nearby borough normally starts in the county jail and court system.
Union County Inmate Population Statistics
The official numbers support one clear point: the county jail population and the federal prison population should not be blended. The county jail capacity comes from the PADOC county prison inspection schedule, which listed Union County Jail for inspection on May 22, 2025. The BOP figures come from public federal facility endpoints captured in June 2026. No source found in the project research published Union County Jail's current inmate count, annual bookings, average length of stay, or demographic split.
| Measure | Figure | Source and date |
|---|---|---|
| Union County Jail rated capacity | 37 beds | PADOC 2025 county prison inspection schedule |
| Union County Jail current population | Not published in sources found | County jail and PADOC public pages reviewed |
| FCI Lewisburg population | 1,115 total, including 620 FCI and 495 camp | BOP endpoint, June 18, 2026 |
| FCI Allenwood Low population | 1,014 | BOP endpoint, June 25, 2026 |
| FCI Allenwood Medium population | 1,078 | BOP endpoint, June 18, 2026 |
| USP Allenwood population | 373 | BOP endpoint, June 18, 2026 |
| Federal prison population physically in Union County | 3,580 | Sum of captured BOP endpoints, June 2026 |
Union County Inmate Population Trends
Union County does not publish enough local jail trend data in the official sources reviewed to build a year-by-year local chart. The available trend table therefore separates what is known from what was not published. The local jail row gives capacity, not population. The federal rows show BOP inmates at facilities inside Union County, not county jail detainees. That distinction protects a reader from treating federal prison counts as proof of a local jail crowding trend.
| Year or date | Count | What it means |
|---|---|---|
| 2025 inspection schedule | 37-bed capacity | Union County Jail capacity, not a daily population count |
| 2026 county website review | Not published | No local jail current population or ADP dashboard located |
| June 18, 2026 | FCI Lewisburg 1,115 | Federal BOP population located in Union County |
| June 18, 2026 | FCI Allenwood Medium 1,078 | Federal BOP population located in Union County |
| June 18, 2026 | USP Allenwood 373 | Federal BOP population located in Union County |
| June 25, 2026 | FCI Allenwood Low 1,014 | Federal BOP population located in Union County |
Local Jail and Federal Prisons
The Union County inmate population is unusual for Pennsylvania because a small county jail sits in the same county as major federal prisons. Union County Jail is a local custody point tied to arrest, bail, preliminary arraignment, jail visits, short sentences, and county court movement. FCI Lewisburg, FCI Allenwood Low, FCI Allenwood Medium, and USP Allenwood are BOP institutions for male federal inmates. A family member may search the same county name and still need two separate systems.
The official Union County Jail page gives local jail contact, visitation, phone, and deposit information. BOP facility pages and the BOP Inmate Locator cover federal custody. No PADOC state prison was found physically in Union County on the official state-prisons list, but a Union County defendant sentenced to Pennsylvania state prison should be searched through the PADOC inmate and parolee locator after transfer.
| System | Who it covers | Lookup path |
|---|---|---|
| Union County Jail | Recent arrests, pretrial detainees, short county sentences, local court holds | Jail phone, in-person inquiry, RTKL request, UJS docket, VINE |
| PADOC | State-sentenced Pennsylvania inmates and parolees | State inmate and parolee locator |
| BOP | Federal sentenced inmates from 1982 to present | BOP Inmate Locator |
| ICE | Immigration detention when applicable | ICE Online Detainee Locator |
Union County Jail Population Laws
Access to Union County inmate population records is governed by several overlapping rules. Pennsylvania's Right-To-Know Law creates the basic path for public-record requests to county agencies. CHRIA controls criminal history record information and can limit what is released to noncriminal justice requesters. County jail operations are also shaped by Pennsylvania statutes and Title 37 county-prison rules, which require written policies for admissions and releases and support PADOC inspection authority.
Key rules:
Pennsylvania Right-To-Know Law gives requesters a formal route to ask Union County for public records unless an exemption applies.
18 Pa.C.S. Chapter 91, the Criminal History Record Information Act, governs how criminal history data may be shared.
37 Pa. Code Chapter 95 sets county correctional institution standards, including admissions and release policy requirements.
61 Pa.C.S. Chapter 17 covers Pennsylvania county correctional institutions.
Search Union County Inmate Records
No official Union County Jail public roster, booking report, or mugshot gallery was located on the county jail page, the sheriff site, the sheriff forms page, or county navigation. That finding changes the search process. A Union County inmate lookup starts with direct jail contact and then moves through court, records-request, notification, state, federal, and immigration channels as needed. The absence of a public roster also means no official county roster search fields, release-retention period, or visible sample profile could be confirmed.
- Start with Union County Jail and ask whether the person is currently housed there, still in intake, released, transferred, or held for court.
- Use the published public office window when calling about nonemergency records, since the county page does not state that a 24-hour public information line exists.
- Search Pennsylvania UJS Case Search for charges, docket numbers, bail, preliminary arraignment events, and court dates.
- Use Union County's RTKL process when a booking sheet, commitment record, release record, charge list, or booking photograph must be requested in writing.
- Check Pennsylvania VINE for custody status and notification if the person is in a covered Pennsylvania custody system.
- Search PADOC, BOP, or ICE when the person may be in state prison, federal prison, or immigration custody rather than the county jail.
Union County Inmate Record Fields
Because no public Union County Jail roster profile was found, the county-jail field list should be treated as a request checklist, not a promise of what appears online. A phone inquiry may confirm current custody, but a written RTKL request is the better route for a formal booking record. Requests should identify the person, the date range, the arresting or committing agency if known, and the exact record sought.
| Field | What it may show |
|---|---|
| Full name | Person booked or held by the jail |
| Date and time booked | Intake timestamp if released under RTKL review |
| Arresting or committing agency | Police, sheriff, probation, court, or other authority |
| Charges or commitment reason | Arrest charges, warrant, hold, sentence, or court commitment |
| Docket, OTN, or complaint reference | Court identifiers that connect custody to filings |
| Bail or bond | Court-set release condition, if public and applicable |
| Booking photo | Not confirmed online; request through RTKL and expect legal review |
| Housing location | Often withheld or limited for jail safety and security |
Union County Records Requests
The county's open-records fallback is specific. Union County directs Right-To-Know requests to Union County Government Center, Attn: Open Records, 155 N. 15th Street, Lewisburg, PA 17837. The county policy says written requests may be made in person, by mail, fax, or electronic means. It also says requests must describe the records with enough detail and include the requester's name and address for the response. The policy does not treat verbal or anonymous requests as RTKL requests.
The Union County Right-To-Know page links the state form, appeal information, policy, and procedures. The procedure file lists standard black-and-white copies at $0.25 per page and certification at $1.00 per record, with specialized documents at actual cost. Jail records can still be redacted or denied where CHRIA, investigative exemptions, juvenile privacy, medical information, personal identifiers, or jail security rules apply.
The official Union County Right-To-Know page shows the county's open-records routing and request materials.
That request channel is the best documented path when a jail record is not available through a public roster.
Union County Arrest Court Records
Jail custody and court records are linked but not the same. After a Union County arrest, the case may move through preliminary arraignment, a magisterial district judge docket, and then the Court of Common Pleas if charges are held for court or filed there. The District Attorney is the prosecutor, while the Clerk of Courts keeps criminal court records. UJS Case Search is often the strongest public source when the jail has no public roster.
UJS searches can use case number, participant name, organization name, offense tracking number, complaint number, police incident number, citation number, or state ID number depending on search mode. Select Union County where the portal offers a county filter. Recent docket entries can lag, and Pennsylvania courts warn that docket sheets are not a substitute for a Pennsylvania State Police criminal-history background check. For a deeper court pathway, use the local court records page after checking custody on the Union County jail inmate records page.
| Office | Role after arrest | Contact from research |
|---|---|---|
| Court of Common Pleas | Criminal trial court and later-stage case events | 103 S. Second Street, Lewisburg; (570) 524-8736 |
| Clerk of Courts | Keeper of criminal court records | 103 S. Second Street, Lewisburg; (570) 524-8751 |
| MDJ 17-03-01 | Preliminary proceedings in Lewisburg | 103 S Second Street; (570) 524-8656 |
| MDJ 17-03-02 | Preliminary proceedings in Mifflinburg area | 343 Chestnut Street Ste #2; (570) 966-2886 |
Union County Jail Mugshots
No official Union County Jail mugshot gallery or daily booking-photo feed was found. The sheriff's active-warrants page includes images for some wanted people and short warrant reasons, but those entries are not proof that a person is currently housed in the jail. Booking photos should be requested through the county's RTKL process when needed, with the understanding that Pennsylvania law does not make every booking photograph automatically public in every context.
Booking-photo limit: UJS docket sheets show charges, bail, events, and dispositions. They do not serve as a mugshot search.
Union County Detention Facilities
The facility map includes one local jail and four federal prisons. The local jail is first because it is the primary place to check after a county arrest. The federal institutions are listed because they are physically in Union County and create much of the visible incarceration population, but they use BOP rules and BOP lookup channels.
- Union County Jail holds pretrial detainees, short county sentences, court holds, and local custody.
- FCI Lewisburg is a medium-security federal prison with a minimum-security camp.
- FCI Allenwood Low is a low-security federal correctional institution near Allenwood.
- FCI Allenwood Medium is a medium-security federal correctional institution near White Deer.
- USP Allenwood is a high-security United States Penitentiary in the Allenwood complex.
Union County Jail Visits
The official jail page focuses on family support rules. Main-side Union County Jail visits are non-contact through glass, with communication by telephone. Video visits are available through IC Solutions. Jail Administration must approve visitors, and visitors need proper identification. The county page limits visits to immediate family unless approved, including mother, father, brothers, sisters, wife or girlfriend, children, grandparents, and in some cases stepchildren.
| Visit type | Schedule | Rules found |
|---|---|---|
| Main-side non-contact visit | Monday-Friday, 8:00 AM-11:30 AM and 12:30 PM-4:00 PM | Approved visitors get two 30-minute visits per week |
| Video visit | Not published on county page | Use IC Solutions and confirm account rules with the jail or vendor |
| Deposits | Lobby kiosk or online | Cash or cards accepted; no personal checks |
Union County Inmate Search FAQ
How big is the Union County inmate population? The county jail capacity found in official research is 37 beds. The federal BOP facilities physically in Union County reported a combined 3,580 inmates in June 2026, but those are federal inmates, not the local jail count.
Is there a Union County Jail roster online? No official public roster, booking report, or mugshot gallery was located on the county jail page, sheriff site, sheriff forms page, or county navigation during the research. Use the jail phone, RTKL, UJS, VINE, PADOC, BOP, and ICE as the fallback chain.
Where are state-sentenced inmates searched? Use the PADOC inmate and parolee locator. PADOC says the locator covers state-sentenced inmates and parolees, is updated daily, and does not include people in county facilities or in another state.
Do federal prisons in Union County use the county jail roster? No. FCI Lewisburg, FCI Allenwood Low, FCI Allenwood Medium, and USP Allenwood are BOP facilities. Search by BOP register number or by name in the federal locator.
