The Union County Inmate Population
Official Union County sources reviewed for this build did not publish a current jail count, daily roster, average daily population, bed capacity, annual booking total, or demographic split. That gap is important. It means the Union County inmate population cannot be verified by refreshing a county roster page. The known local anchor is the Union County Sheriff's Office and jail function at the courthouse hub in Jonesboro. The Illinois Sheriffs' Association directory confirms Sheriff David Wilkins, Jail Administrator Anthony Pena, the public office phone, the county service-area population, and the county's square miles, but it leaves the jail-bed field blank.
The practical population question is usually about a person rather than a count. A newly arrested person may be in the sheriff's booking process, housed for Union County at another facility, released with a court date, or moved into a different custody system after a case changes. Older official county records also show Jackson County detention invoices and an Anna-related email about prisoners taken to Jackson County. Those records do not prove the current housing arrangement, but they do show why the first question should be where the person is physically held.
Union County Inmate Population Data
The strongest published numbers are county context numbers, not a jail census. The Illinois Sheriffs' Association Union County directory lists the sheriff's office contact facts and the county's population and area. The Prison Policy Initiative provides statewide incarceration context, but it does not turn into a Union County jail count. The Union County inmate population should therefore be reported with clear labels: what is known, what is not published, and which source controls each fact.
| Measure | Figure | Source Status |
|---|---|---|
| Sheriff service-area population | 17,000 | Illinois Sheriffs' Association directory, inspected 2026 |
| County area | 414 square miles | Illinois Sheriffs' Association directory, inspected 2026 |
| Union County Jail bed capacity | Not published | Directory leaves jail beds blank; no official county capacity report located |
| Current jail population | Not published | No official roster, dashboard, or jail census located |
| Average daily population | Not published | No official ADP report located |
| Illinois incarceration rate | 433 per 100,000 people | Prison Policy Initiative Illinois profile, statewide context |
| Illinois annual local jail bookings | At least 173,000 people | Prison Policy Initiative Illinois profile, statewide context |
The Prison Policy Initiative Illinois correctional-population table is useful for nearby context. It lists many state, federal, and local facilities, including nearby southern Illinois prisons and federal facilities outside Union County. It does not create extra Union County facility pages, and it should not be used to invent a Union County jail count.
The Prison Policy Initiative table is a useful source for statewide and nearby correctional context, and its capture is shown in this project image from the Illinois correctional-population table.
The image supports the page's main caution: nearby correctional populations are not the same as a current Union County jail population.
Union County Inmate Population Trends
A trend table can be more honest than a false estimate. The research found several dates that matter, but none of them give a current daily jail census. Older county expenditure records show detention billing involving Jackson County. A later county email asked how many prisoners in Anna cases were taken to Jackson County over a prior period. Those records are local, official, and relevant to housing questions. They are not a daily population dashboard.
| Year | Union County Jail Count | What the Source Supports |
|---|---|---|
| 2013 | Not listed | PPI table lists many Illinois local jails but no Union County local jail entry |
| 2018 | Not a population figure | Official expenditure records list Jackson County Sheriff Department detention invoices |
| 2020 | Not a population figure | Official email discusses prisoners in Anna cases taken to Jackson County |
| 2024 | Not located | No clean official Union County ADP figure captured |
| 2026 | Not published | No official current roster, dashboard, or population count located |
For a reader, the trend is less about a graph and more about routing. The Union County inmate population may include local arrestees, people held elsewhere for Union County, criminal defendants with cases in the First Judicial Circuit, people sentenced to IDOC, and people in federal or immigration custody. Each group has a different public lookup path.
Who Counts in Union County Custody
The phrase Union County inmate population can point to several groups. A person booked after a local arrest is a sheriff or jail question. A defendant whose charges have been filed is also a court-record question. A person sentenced to state prison becomes an IDOC search question. Federal pretrial custody may involve the U.S. Marshals Service before a BOP record appears. Immigration detention is separate and uses ICE's locator.
| Population Group | Likely System | Public Lookup |
|---|---|---|
| New local detainee | Union County Sheriff's Office | Call the sheriff; use FOIA if records are needed |
| Person housed outside the county for Union County | Sheriff plus receiving jail | Call Union County first, then confirm the receiving facility |
| Filed criminal defendant | First Judicial Circuit | Search Judici or call the Circuit Clerk |
| Sentenced Illinois prisoner | Illinois Department of Corrections | Use IDOC Individual in Custody Search |
| Federal prisoner | BOP or U.S. Marshals | Use BOP for sentenced custody; contact federal channels for pretrial custody |
| Immigration detainee | ICE | Use ICE Online Detainee Locator |
Important: No single Union County search box covers local jail custody, court cases, IDOC prison custody, federal custody, and ICE detention.
Laws Governing Union County Inmates
Illinois law explains why public arrest information exists even when a county does not publish an online roster. 5 ILCS 140/3 requires public bodies to make public records available unless an exemption or other law applies. 5 ILCS 140/2.15 is more specific for arrest reports and criminal-history records. It covers identifying information, charges, arrest time and place, arresting agency, and custody received, discharged, or transferred information when maintained and releasable.
Jail operations have a different legal base. The Illinois County Jail Act requires counties to have jail facilities and allows a county to satisfy that duty through a jointly maintained facility. That matters in Union County because older official county records show out-of-county detention billing. 730 ILCS 5/3-15-2 gives IDOC a role in minimum standards for county and municipal jails, and 20 Ill. Adm. Code Part 720 sets county-jail standards tied to health, safety, and security.
Illinois FOIA 5 ILCS 140/2.15 supports access to specified arrest-report information, including a photograph when and if available, but it does not require Union County to publish a mugshot gallery.
The Illinois FOIA arrest-report statute is shown in this captured source image from the Illinois General Assembly page for 5 ILCS 140/2.15.
That source is central for Union County booking records because the county did not publish a public roster or mugshot gallery in the official sources reviewed.
How to Search Union County Inmates
A Union County inmate search should start with the agency that can answer the real-time custody question. Because no official online Union County jail roster was located, call the Union County Sheriff's Office at 618-833-5500 for current custody, housing location, release status, and whether a person was transferred. Ask whether the person is held locally or for Union County at another facility. That wording is useful because official county records show older out-of-county detention activity.
- Gather the person's full legal name, date of birth, arrest date, arresting agency, and any case or warrant number.
- Call the Union County Sheriff's Office and ask whether the person is booked, released, transferred, or held for another agency.
- If routine phone information is limited, use the official Union County FOIA form for arrest or booking records.
- Search Union County cases on Judici after charges are filed.
- Use Illinois VINE for custody or case notifications where available.
- Use IDOC Individual in Custody Search after a state-prison sentence.
- Use the BOP Inmate Locator or ICE locator for federal or immigration custody.
FOIA is not a fast release tool. For urgent release, transport, bond, court-time, or medical questions, the sheriff or court is the first contact. FOIA is better for non-urgent records such as arrest reports, booking sheets, custody dates, and booking photographs when available.
Union County Jail Roster Fields
The official roster field inventory is simple because no official Union County online roster was found. That should be stated plainly. If a new county roster appears later, field claims should be checked from that source rather than borrowed from another Union County or from a private jail site.
| Field Label | Type | Required | Union County Status |
|---|---|---|---|
| Last name | Not available | Not available | No official Union County roster search form located |
| First name | Not available | Not available | No county inmate-search interface located |
| Booking number | Not available | Not available | Ask sheriff or request records if known |
| Facility filter | Not available | Not available | Physical housing must be confirmed by phone |
A missing roster does not mean missing records. Union County still has sheriff records, court records, FOIA records, and state or federal custody records. The difference is that the reader must route the request to the office that owns the record.
What Union County Inmate Records Show
For local arrest records, Illinois FOIA Section 2.15 is the best field guide. It points to identifying information, charges, arrest time and location, arresting or investigating agency, and custody received, discharged, or transferred dates when the person is incarcerated. Redactions can still apply for investigations, safety, correctional security, juvenile records, and other protected material.
| Record Field | What It Can Show |
|---|---|
| Name, age, address, photograph | Identifying information when maintained and releasable, including photograph when and if available |
| Charges | Arrest-related charges, which may differ from the charges later filed in court |
| Arrest time and place | Where and when the arrest occurred |
| Agency | The arresting or investigating law-enforcement agency |
| Custody dates | Time and date received into, discharged from, or transferred from custody when incarcerated |
| Redactions | Information withheld under FOIA exemptions or other privacy and safety rules |
Union County Court Records After Arrest
Booking and court records are not the same record. A person can be booked before a case appears online. Once the prosecutor files charges, the First Judicial Circuit and the Circuit Clerk become the public case-record path. Judici is the located online case-search portal for Union County, and the Circuit Clerk handles case numbers, court dates, certified copies, and records not visible online.
The First Judicial Circuit Union County court directory lists Circuit Clerk Keri E. Clark, State's Attorney Tyler Tripp, judges, public defenders, and probation contacts. The court directory is a court and records-routing source, not a real-time jail roster.
The Union County court directory source is shown in this captured image from the First Judicial Circuit page for Union County.
Use the court source after charges are filed; use the sheriff first when the question is whether someone is in custody right now.
Union County State and Federal Inmate Search
Sentenced state-prison custody is handled by the Illinois Department of Corrections, not by a Union County jail roster. IDOC search results can show an IDOC number, name, parent institution, custody status, physical profile fields, admission and release fields, and sentencing information. Those are prison fields. They do not show a Union County jail housing unit or local booking counter.
The IDOC search page is a key fallback for Union County inmate population questions after sentencing. The official IDOC Individual in Custody Search is shown in this captured source image.
Federal and immigration custody use separate systems. BOP covers federal inmates from 1982 to present, while U.S. Marshals may be relevant for federal pretrial custody. ICE searches require an A-number or exact biographical information. None of those federal tools is a Union County mugshot gallery.
Union County Detention Facilities
The facility map resolves to one Union County facility page. No state prison, BOP prison, ICE detention center, or U.S. Marshals detention center was located physically inside Union County. Nearby Shawnee Correctional Center, Vienna Correctional Center, USP Marion, FCI Greenville, and MCC Chicago may matter as state or federal lookup context, but they should not be treated as Union County facilities.
- Union County Jail - local sheriff jail function for Union County arrestees, pretrial detainees, and short local-sentence detainees when held through the county process. Current physical housing should be confirmed by phone.
Union County Inmate Search Terms
Short definitions help keep Union County inmate population searches from mixing court, jail, prison, and federal terms.
- Booking
- Administrative processing after an arrest, often including identity, charges, fingerprints, property, and a photo.
- Roster
- A public list of people currently held by a jail. No official Union County online roster was located.
- Pretrial release
- Release before trial under court-set conditions in Illinois, replacing many older money-bail assumptions.
- Detainer
- A hold or notice from another agency that can affect release or transfer.
- IDOC number
- The Illinois state-prison identifier used after a person enters IDOC custody.
Union County Inmate Population FAQ
Is there an official Union County inmate roster?
No official Union County online jail roster, booking report, or current-inmate search was located in the official sources reviewed. Call the sheriff's office for current custody and use FOIA for releasable records.
How big is the Union County inmate population?
A current jail population count was not published in the official sources reviewed. The strongest local population number is the sheriff service-area population of 17,000, which is not a jail count.
Where are Union County court charges found?
After charges are filed, search Union County cases through Judici or contact Circuit Clerk Keri E. Clark. Court records show the formal case path, not real-time housing.
Do Union County mugshots appear online?
No official Union County mugshot gallery or roster photo page was located. Illinois FOIA supports requesting a photograph when and if available, subject to exceptions.
When should IDOC be searched?
Use IDOC after a person is sentenced to Illinois state-prison custody. IDOC is not the right first stop for a new Union County pretrial booking.
Can VINE replace the sheriff phone call?
No. Illinois VINE can provide custody and case notifications where available, but current Union County housing should still be verified with the originating agency.
