The Peoria County Inmate Population
The Peoria County inmate population is held mainly at the Peoria County Jail on North Maxwell Road, which the Sheriff's Corrections Division calls the eighth largest jail in Illinois. The jail holds adults in local custody. That includes people booked after an arrest, people picked up on a warrant, people waiting for a first court date, and people serving short local sentences. Three separate facilities hold people in or from the county. The sheriff's jail handles adult county custody. The Illinois Department of Corrections runs a transition center in downtown Peoria for sentenced state residents. A separate juvenile detention center holds minors under the juvenile court, not the adult jail roster.
Several things move the count up and down. New arrests and warrant arrests raise it. Bond and pretrial release decisions, dismissals, and transfers to state prison lower it. Illinois changed how pretrial release works, so fewer people sit in jail only because they cannot pay a set bond amount. When a person is convicted and sentenced to prison, the county jail is no longer the right place to look, because that person moves to the state system.
The county made one change that still confuses searchers. The sheriff discontinued the printed Daily Commitment Report at the end of 2018 and moved jail records online. People who go looking for a daily booking list will not find one, and that gap sends them to commercial sites instead of the official records page.
The official records show what the Peoria County inmate population looks like today, but the raw daily count for the adult jail is part of the picture and not a published web figure. The lead-in below uses the county's own corrections page, which sets out staffing and the jail's statewide ranking.

Peoria County Inmate Population Statistics
Hard numbers for the adult jail are limited in the county's published web pages, so only sourced figures appear here. The county describes the Peoria County Jail as the eighth largest jail in Illinois, and the Corrections Division lists a sizable staff to run it. The state corrections facility in Peoria publishes its own capacity and population. The adult jail's exact rated capacity and average daily population were not posted in the captured county web text, so they are left out rather than guessed.
The figures below are the verified numbers from official Peoria County and Illinois Department of Corrections pages. Where a measure was not published, the table says so plainly.
| Measure | Figure | Source / Year |
|---|---|---|
| Peoria County Jail statewide ranking | 8th largest in Illinois | Sheriff's Corrections page, 2026 |
| Corrections officers | 53 | Sheriff's Corrections page, 2026 |
| Jail techs | 10 | Sheriff's Corrections page, 2026 |
| Peoria Adult Transition Center operational capacity | 249 | IDOC facility page, 2022 census |
| Peoria Adult Transition Center population | 241 | IDOC facility page, as of 6/30/2024 |
| Juvenile Detention Center capacity | 63 beds | Tenth Judicial Circuit page |
| Adult jail rated capacity / daily population | Not published online | See jail inspection reports |
Peoria County Inmate Population Trends
Year over year jail counts are not posted on the county site, so a clean multi-year average daily population chart is not available from official Peoria sources. What the official record does show is how the public data picture has shifted over recent years. The county moved away from a daily printed report, the state continues to publish transition center figures, and the sheriff now files annual jail inspection documents.
| Year | Reported Change | Source |
|---|---|---|
| 2018 | Daily Commitment Report discontinued; jail records moved online | Sheriff's Public Information page |
| 2024 | Peoria Adult Transition Center population reported at 241 | IDOC facility page, 6/30/2024 |
| 2025 | Jail inspection report published for the adult jail | Peoria County Jail Inspection Reports page |
For a true count trend, the jail inspection report and county board records are the next stop, since the web pages do not carry a year-by-year figure.
Who Makes Up the Peoria County Inmate Population
The inmate population splits across custody types more than across any single profile. The adult jail mixes people who have not yet had their day in court with people serving short local sentences. The state transition center holds only sentenced adult men. The juvenile center holds minors and is tracked apart from the adult roster. The county does not publish a public male, female, race, or age breakdown for the jail, so those splits are described in plain terms rather than with invented percentages.
- Pretrial vs sentenced - the adult jail holds both people awaiting court and people serving short local time.
- Adult vs juvenile - minors go to the separate juvenile detention center, not the jail roster.
- County vs state custody - the Peoria Adult Transition Center holds sentenced state men, found through the state locator.
- Holds and detainers - a person may also be held for another agency, which can keep them in custody after local matters clear.
Peoria County Jail Capacity and Overcrowding
The county leans on its ranking rather than a single capacity number. Calling the jail the eighth largest in Illinois signals a large operation, and the Corrections Division lists jail techs, dozens of officers, a classification director, several sergeants, and superintendent staff to run it. A formal rated capacity for the adult jail was not visible in the captured county web text. The sheriff does publish annual jail inspection reports, and those state inspections are the official route for capacity, condition, and compliance details.
The state side is clearer. The Peoria Adult Transition Center reports an operational capacity of 249 and a population of 241 as of mid-2024, which is close to full but not over. That facility is a reentry setting, not the county jail, so its numbers should never be read as the jail's count.
Laws Governing the Peoria County Inmate Population
A short stack of Illinois laws makes the data public and sets the rules behind it. Open records law is why booking records, corrections records, and jail data can be requested at all. State jail standards govern how the jail itself runs. A separate identification act controls criminal history records and the routes to seal or clear them. Pretrial release rules shape who stays in custody before trial. Each one is summarized in plain English below.
Key Statutes:
Illinois Freedom of Information Act, 5 ILCS 140 - public bodies must release records, including jail and booking records, unless an exemption applies.
County Jail Standards, 20 Ill. Admin. Code Part 701 - state rules cover admission, release, classification, sanitation, medical care, and discipline in county jails.
Illinois Criminal Identification Act, 20 ILCS 2630 - governs criminal history records and the rules for sealing or expunging them.
Illinois pretrial release framework - the state changed pretrial release, so local bond steps must be read with the current court order.
Peoria County and the State Prison Population
People from Peoria County feed into the state prison count after sentencing. A person can begin at the county jail as a pretrial detainee, then move to the Illinois Department of Corrections once a judge imposes a prison sentence. From that point the county roster is the wrong tool, and the statewide IDOC inmate search is the right one. A Peoria resident in state custody may be housed anywhere in Illinois, not only in Peoria. The Peoria Adult Transition Center is one state facility in the county, but it is a reentry center near the end of a sentence and has its own rules.
How to Search the Peoria County Inmate Population
The current path runs through the sheriff's records page, not a daily report. The Jail and Inmate Information page points to the county's Tyler Technologies records portal, and the inmate information line stands as a backup when the portal is unclear. Start with a last name. A booking number helps if you have one.
The walkthrough below works whether the person was just booked or has been held for days.
- Open the sheriff's records portal from the Jail and Inmate Information page.
- Search the jail records by last name, then add a first name to narrow a common surname.
- If the person was just booked and does not appear, call the inmate information line at 309-697-7841.
- Open the matching record to read booking and custody details.
- If the person was sentenced to prison, switch to the state IDOC locator instead of the county portal.
The lead-in below opens the official county records portal that the sheriff links for jail records.
The Peoria County records portal is where the sheriff directs the public for jail record searches.
Bookmark that portal, since it has replaced the old daily report as the front door to the Peoria County inmate population.
Current Inmate Lookup in Peoria County
For a person believed to be in the jail right now, the records portal is the first stop and the inmate information line is the second. New bookings can take time to appear, so a phone check fills the gap. The county also runs a separate warrant list that publishes a name, an offense, and a case number, which can confirm why someone may have been taken into custody. That warrant list is a subset and updates once a day, so it is a clue rather than a full record.
Note: A just-booked person may not show online for a short time, so the inmate information line is the fastest way to confirm a brand new booking.
Past and Released Inmate Records
Released and past inmates are harder to track than current ones. The online jail records focus on current custody, and the county no longer prints a historical daily list. For an older booking, a booking photo, or an incident record, the sheriff's FOIA process is the official route. A request can be filed online through JustFOIA or in person, and the office responds within five business days. If the person was sentenced and moved to state prison, the released or current status lives in the state locator, not the county portal.
What a Peoria County Inmate Record Shows
A jail record ties a person to a booking event and a custody status. In practice that means a name, a booking, the charges or warrant behind the hold, any bond information, and whether the person is still in custody. The county confirms that booking photos and booking documents are kept as corrections records, even though the public portal display needs a live check to confirm every field. The clearest captured example of a public county record is the warrant list, which shows three fields for each person.
| Field | What It Shows |
|---|---|
| Name | The person named, shown last name first, such as ACOSTA, CAMERON REIS. |
| Offense | The underlying offense, such as aggravated battery, retail theft, or unlawful possession. |
| Case Number | The court case number, such as 2024-CF-0000321, used to pull the court file. |
Several terms come up when reading any inmate record. The short glossary below defines them so the record reads clearly.
- Booking
- The intake process after an arrest, when identity, charges, and custody status are entered.
- Classification
- The jail process that assigns a security level and housing; Peoria lists a classification director on staff.
- Bond
- Money or a condition tied to release; Illinois has changed its pretrial release rules.
- Detainer
- A hold from another agency that can keep a person in custody even after local charges clear.
- Remand
- A court order returning a person to custody, often after a hearing.
County Jail vs. State Prison: Where to Look
The single most common mistake is searching the county roster for a state prisoner. Pretrial detainees and short local sentences sit in the county jail under the sheriff. Sentenced felons serve their time in an Illinois Department of Corrections prison, found through a different locator. The table below maps each part of the inmate population to the right tool.
| County Jail | State Prison (DOC) | |
|---|---|---|
| Who Is Held | Pretrial and short sentences | Sentenced felons |
| Run By | Peoria County Sheriff | Illinois Department of Corrections (IDOC) |
| Where to Look | County jail records portal | IDOC Individual in Custody Search |
| Stays Listed | While in county custody | Through the state sentence |
State and Federal Inmate Search
Three locators cover the parts of the population the county roster does not. The IDOC Individual in Custody Search handles sentenced state prisoners. The Federal Bureau of Prisons locator handles sentenced federal inmates. The ICE Online Detainee Locator handles immigration detention. The state search accepts three methods, shown in the table below.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Radio + text | One method required | Example: Smith or Smit |
| IDOC Number | Radio + text | One method required | Example: K01234 |
| Birthdate | Radio + text | One method required | Example: 04-01-1965 |
| Find | Button | Yes | Submits the search |
The lead-in below opens the state locator that covers sentenced custody from across Illinois.
The IDOC Individual in Custody Search is the statewide tool for sentenced state prisoners.
Use that locator the moment a Peoria County case ends in a state prison sentence, because the county roster will no longer carry the person.
Peoria County Detention Facilities
Three facilities hold people in or from Peoria County, and each serves a different part of the inmate population. Knowing which one applies tells you which roster or locator to open. Booking detail for current jail inmates also appears on the jail inmate records page, and booking photos are covered on the jail roster mugshots page.
- Peoria County Jail - the sheriff's adult jail for pretrial detainees and short local sentences.
- Peoria County Juvenile Detention Center - a secure 63-bed center for minors under the juvenile court.
- Peoria Adult Transition Center - a state reentry facility for sentenced adult men, searched through IDOC.
Peoria County Inmate Population FAQ
How big is the Peoria County inmate population?
The county calls the Peoria County Jail the eighth largest jail in Illinois, but it does not post a daily count online. The exact rated capacity and average daily population were not published in the captured county web pages, so the annual jail inspection report and county board records are the next place to look for a firm number.
How do I search the Peoria County inmate population?
Start at the sheriff's Jail and Inmate Information page, which links the county records portal, and search by last name. If a new booking does not appear, call the inmate information line at 309-697-7841. For a sentenced prisoner, use the state IDOC locator instead of the county portal.
Can I look up a released or past inmate?
The online jail records focus on current custody. For an older booking or a historical record, file a public records request with the sheriff through JustFOIA or in person, and expect a response within five business days. A sentenced person who moved to state prison shows up in the IDOC locator.
Where did the Daily Commitment Report go?
The sheriff discontinued the Daily Commitment Report at the end of 2018 and moved jail records online. There is no longer a daily printed booking list, so the records portal and the inmate information line are the current routes.
Is the Peoria Adult Transition Center the same as the jail?
No. The transition center is a state Illinois Department of Corrections facility for sentenced adult men near the end of a sentence. It is found through the IDOC locator, not the county jail roster, and its capacity and population are reported separately.
How do I get notified about a release or court date?
Peoria County supports VINELink, which provides custody status by phone, internet, or email and can notify you of a release, escape, or court appearance. The VINE phone line runs around the clock for registered users.
