Henderson County Inmate Population
The Henderson County inmate population should not be read as the number of people inside one building at all times. Henderson County Jail is the local sheriff facility in Oquawka, but IDOC inspection comments for 2024 and 2025 recorded no detainees in the jail on the inspection dates and stated that male detainees may be housed at Warren County Jail and female detainees may be housed at McDonough County Jail when necessary. That makes Henderson County a useful example of a small county where the legal custody, court case, and physical jail location may not all be the same.
Several agencies can appear in one person's path. The Henderson County Sheriff's Office handles local arrest, booking, and jail custody questions. The Henderson County Circuit Clerk and Judici handle court records after charges are filed. IDOC handles sentenced state prisoners after transfer from county custody. BOP and ICE cover federal and immigration custody. Illinois VINELink adds notification access, but it does not replace the sheriff, clerk, or corrections locator.
Henderson County Inmate Population Statistics
Recent Henderson County jail statistics show very low local detention numbers. IDOC's 2024 and 2025 inspection reports list 10 total beds at Henderson County Jail and zero people in custody on each inspection date. Older sources used a 14-bed figure, including the 2023 IDOC inspection and Illinois Sheriffs' Association directory. Vera Incarceration Trends data gives a 2024 total jail population figure of 2 and a 2019 figure of 9 for Henderson County, Illinois, FIPS 17071.
| Measure | Figure | Source / Year |
|---|---|---|
| Henderson County Jail capacity | 10 total beds, 10 male, 0 female | IDOC 2024 and 2025 inspections |
| Older listed capacity | 14 beds | IDOC 2023 and Illinois Sheriffs' Association |
| 2025 inspection-date population | 0 | IDOC inspection, September 17, 2025 |

Henderson County Inmate Trends
Henderson County jail numbers move sharply because the base is so small. A change of only a few detainees can look like a large rate swing. The more durable recent trend is the inspection pattern: 3 people at the 2023 IDOC inspection, then zero people at the 2024 and 2025 inspections, with IDOC noting the effect of the SAFE-T Act and contract housing in Warren and McDonough Counties. Vera data also shows a lower 2024 figure than 2019.
| Year | Jail Population / ADP-style Figure | Notes |
|---|---|---|
| 2024 | 2 | Vera county CSV; IDOC inspection-date population was 0. |
| 2019 | 9 | Vera county CSV; rated capacity 14. |
| 2018 | 9 | Vera county CSV; rated capacity 14. |
| 2017 | 16 | Vera county CSV; above 14-bed capacity, but small-county estimates should be read carefully. |
| 2014 | 10 | Vera county CSV; rated capacity 14. |
| 2010 | 6 | Vera county CSV; rated capacity 14. |
Henderson County Inmate Makeup
Vera's 2019 row listed total jail population 9, pretrial custody 8, and sentenced custody 1. The same small-county dataset has sex and race subtotals that can exceed the total because of estimation or rounding, so those categories should not be turned into percentages. IDOC's 2024 and 2025 inspection-date population was zero, which means those inspections did not create a useful local demographic snapshot. The strongest supported local point is that the active local population has been very low and may be housed outside Henderson County by sex-specific contract arrangements.
- Pretrial and sentenced mix: Vera listed 8 pretrial and 1 sentenced person in 2019.
- 2024 and 2025 inspections: IDOC recorded zero people in Henderson County Jail on the inspection dates.
- Male housing fallback: Henderson inspection comments point to Warren County Jail.
- Female housing fallback: Henderson inspection comments point to McDonough County Jail.
Henderson County Jail Population Laws
Illinois law explains why jail population and arrest information can be requested, and why some details may still be withheld. The public-access rule starts with FOIA, while jail operations are shaped by IDOC standards authority and the Illinois County Jail Act. Henderson County's contract-housing pattern also fits the County Jail Act provision that allows use of a sufficient jail in another county when needed.
Key Statutes:
5 ILCS 140/3 sets written public-record request channels and the ordinary five-business-day FOIA response period.
5 ILCS 140/2.15 covers core arrest information, including a photograph when and if available, within 72 hours.
5 ILCS 140/7 allows exemptions for law-enforcement interference, safety, confidential sources, and correctional security.
730 ILCS 5/3-15-2 gives IDOC authority to establish county and municipal jail standards.
730 ILCS 125 covers county jail maintenance, the sheriff's jail role, and use of another county jail when local facilities are insufficient.
Henderson County Jail Capacity
Recent records do not show current overcrowding at Henderson County Jail. The opposite issue appears in the inspection record: zero local detainees on the 2024 and 2025 inspection dates, with vendor contracts and regional housing arrangements maintained for future or changing need. The 2025 report describes a 1935 jail last renovated in 1978, with A and B block rooms and C and D dormitories. The 2024 report lists physical plant work, ligature-point removal, new shower heads, and other safety upgrades, while the 2025 report lists no noncompliances and facility improvements.

Search Henderson County Inmates
The current Henderson County inmate population search is app-first, then phone-supported. No official web roster was found for Henderson County, Illinois. The Henderson Co. Sheriff's Office app is listed on Google Play and Apple, while the sheriff phone line is the fallback for current custody and physical housing location. If the person has moved to state prison, IDOC is the correct tool. If the person is in federal or immigration custody, use BOP or ICE.
- Open the Henderson Co. Sheriff's Office mobile app and verify it is the Illinois app.
- Use the in-app inmate lookup or custody feature if available on the device.
- Call Henderson County Sheriff's Office at 309-867-4291 if the app does not show a match.
- Ask whether the person is in Henderson County Jail, Warren County Jail, or McDonough County Jail.
- Switch to IDOC, BOP, ICE, or Judici when the custody stage or record type is no longer local jail custody.

Henderson County Inmate Records
A Henderson County inmate record may be an app result, a phone-verified custody status, a sheriff arrest report, a VINE notification record, or a court filing that appears after charges are filed. The app-store pages did not reveal sample inmate fields. Illinois FOIA section 2.15, however, identifies arrest information that can be requested from a criminal justice agency, including identifying information, charges, arrest time and location, arresting agency, and custody receive, discharge, or transfer dates if the person was incarcerated.
| Record Field | Best Henderson County Source |
|---|---|
| Current custody | Sheriff app, sheriff phone, or VINE. |
| Physical jail location | Sheriff phone, then Warren or McDonough if transferred. |
| Booking photo | FOIA request when available; no public web gallery located. |
| Filed charges | Judici or Henderson County Circuit Clerk. |
| State prison location | IDOC Individual in Custody Search. |
County Jail vs State Prison
Henderson County inmate population searches often fail when the wrong system is used. County jail custody covers recent arrests, pretrial detention, short local sentences, and housing pending court action. State prison custody begins after sentencing and transfer to IDOC. Federal and immigration custody use separate national locators. A person may still have a Henderson County court case even after leaving Oquawka or after being housed in a neighboring jail.
| County Jail | State Prison | Federal / ICE | |
|---|---|---|---|
| Who is held | Pretrial and local detainees | Sentenced state prisoners | Federal prisoners or immigration detainees |
| Run by | Sheriff or contract county jail | Illinois Department of Corrections | BOP or ICE |
| Where to look | Sheriff app and phone | IDOC locator | BOP or ICE ODLS |
Henderson County Detention Facilities
Three facilities are part of the Henderson County inmate population map. The Oquawka jail is the home sheriff facility. Warren County Jail and McDonough County Jail are not Henderson County agencies, but they are documented regional housing sites for Henderson detainees when needed.

Henderson County Inmate Population FAQ
How big is the Henderson County inmate population?
Recent sourced figures are very small. IDOC recorded zero people in Henderson County Jail on the 2024 and 2025 inspection dates, and Vera listed a 2024 jail population figure of 2. Those figures do not mean Henderson County never has detainees. They mean the count is low and may include contract housing outside Oquawka.
How do I search the Henderson County inmate population?
Start with the Henderson Co. Sheriff's Office mobile app. If the app does not answer the question, call 309-867-4291 and ask whether the person is in Henderson County Jail, Warren County Jail, or McDonough County Jail. Use IDOC only for sentenced state prisoners.
Does Henderson County publish mugshots online?
No official Henderson County web mugshot roster or recent-bookings gallery was located. Illinois FOIA allows request of a photograph when and if available, subject to exemptions and limits.
Where are court charges found after arrest?
After the prosecutor files charges, use Judici or the Henderson County Circuit Clerk. Court records after an arrest are separate from jail custody and booking-photo records.
