Rock Island County Inmate Population Overview

The Rock Island County inmate population is split across two very different custody systems. The local system is the Rock Island County Jail, also called the Rock Island County Correctional Center, where the sheriff handles central booking for county arrests. That facility holds adults awaiting court, people serving short local sentences, people held for other agencies, and detainees housed under federal or neighboring-county arrangements. The state system is East Moline Correctional Center, an Illinois Department of Corrections prison for sentenced adult men. The two populations sit in the same county, but they are counted, searched, and managed by different agencies.

For public search purposes, the county jail count is the number that changes fastest. A person can move from arrest to booking to first appearance to release in a short span, and the county page reports an average length of stay of seven days. That short stay helps explain why the sheriff can report an annual jail population of more than 10,000 while the average daily population is far lower. The Rock Island County inmate population is therefore best read by source and date: a roster snapshot shows who is listed now, a county page gives a standing local average, and a procurement document may use a different 12-month measurement period.

The county's Inmate Services page is the best matching image source for the local population and jail-capacity discussion.

Rock Island County Inmate Population Statistics

Published Rock Island County inmate population figures are not all the same type of count. The county's inmate-services page lists 325 total capacity for the Jail and Justice Center, an average daily inmate count of 260, and an average stay of seven days. A 2025 inmate communications request for proposals lists 325 beds but gives a lower 12-month average daily population of 173 for that procurement period. A public Zuercher roster query on June 10, 2026 returned 233 total records. Each number is useful, but none should be treated as a substitute for the others.

Rock Island County Jail Population Trends

The long trend shows why the current jail population must be read against the county's facility history. Vera/BJS-derived county rows show 80 people in the jail population in 1970, 87 in 1985 before the current jail opened, and 156 in 1986 when the new Correctional Center came online. Capacity rose again after the Justice Center annex opened at the end of March 2001. By 2005, the trend row showed 238 people and 329 capacity, a scale close to the present county bed count.

Recent figures point in different directions because they measure different things. The county public page lists 260 as the average daily inmate count. The 2025 communications RFP lists a 173 average over the last 12 months. The June 10, 2026 roster sample returned 233 records. Those figures put jail utilization at about 80.0%, 53.2%, or 71.7% of the 325-capacity figure, depending on the basis. That spread is a reason to date-stamp every Rock Island County inmate population number.

Who Makes Up Rock Island Inmate Records

Rock Island County does not publish a standing public aggregate that separates pretrial detainees from sentenced local detainees, felony from misdemeanor custody, or county holds from outside-agency holds. The public roster does show race, sex, age, arrest date, release date, and hold-reason text for each visible row. A June 10, 2026 roster aggregate found 205 male records, 27 female records, and one not specified. The same snapshot showed 124 White records, 102 Black or African American records, four Not Specified records, and three Unknown records. Those figures describe one roster pull, not a yearly demographic report.

County jail status is also broader than local criminal charges. The 2024 IDOC jail inspection says the Rock Island County Jail houses detainees for the U.S. Marshals Service and Scott County, Iowa. The sheriff's page says the facility houses inmates locally and for federal agencies and neighboring communities. In roster language, that may appear as charge text, warrant text, or "Housing for other Agency" rather than a simple local case.

Pretrial detainee

A person held before a case is resolved, often after arrest and before later court hearings.

Sentenced prisoner

A person serving a sentence, often moved to IDOC if the sentence is state-prison custody.

Detainer or hold

A separate agency or case reason that can keep a person in custody even if one charge changes.

Roster snapshot

A count from a specific search date, not the same thing as average daily population.

Rock Island County Jail Capacity

The county's own capacity figure is 325 for the Jail and Justice Center together. The Illinois Sheriffs' Association lists 326 beds, and a Vera trend row for 2023 shows 329 capacity, so the build should treat 325 as the primary county figure and acknowledge nearby secondary figures only when useful. The 2024 IDOC inspection did not frame the facility as over capacity in the captured comments, but it did record detainee concerns about hot water, showers and windows in older jail areas, commissary hygiene prices, and property boxes for food. Officials responded that water heaters were purchased and shower work was part of painting or renovation.

Facility age also matters. The Sheriff's Office says the current Correctional Center opened in 1986 and the Justice Center annex opened in 2001. Later county procurement files describe exterior waterproofing work, swing-door lock replacement, and older Folger Adams lock hardware. Those sources do not change the public roster, but they show why the Rock Island County inmate population is housed in a downtown jail complex with several decades of maintenance history.

Laws Governing Rock Island Inmate Data

Illinois law explains why some Rock Island County inmate population and booking information is public while other jail records stay internal. The county roster is a public index of custody information, not the full jail file. State jail standards require broader booking and personal records inside the jail, but the public roster leaves out fields such as full date of birth, medical details, property records, internal discipline, attorney contacts, and detailed housing information.

Rock Island County State Prison Population

East Moline Correctional Center adds a state-prison population physically located in Rock Island County, but it is not part of the county jail roster. IDOC lists East Moline as a minimum-security adult male facility with operational capacity of 925 and a population of 482 as of June 30, 2024. It opened in November 1980 after conversion from a mental health facility and consists of 26 buildings over more than 430,000 square feet. Programs include GED, Adult Basic Education, the Augustana Prison Education Program bachelor's degree, career technologies, construction, culinary arts, counseling, veterans transition, library, AA, NA, worship services, Toastmasters, and tutoring.

A person sentenced from a Rock Island County case to IDOC custody should be searched through the IDOC Individual in Custody Search, not the county Zuercher roster. IDOC searches use last name, birthdate, or IDOC number and return state custody fields such as IDOC number, parent institution, status, offense, sentence, county, mittimus or case number, projected parole, and discharge information when public.

How to Search Rock Island County Inmates

The official current-jail search channel is the Rock Island County Zuercher Inmate Listings portal. The sheriff's site labels the link "Inmate Listings," and the portal text says it shows a current list of inmates held in the Correctional Facility. The portal also warns that if a subject is not listed but was in custody, the person has been released or transferred. That warning is important for released people, IDOC transfers, federal transfers, and outside-agency holds.

Start with a name when the person is likely still in the county jail. Use the date filters when an arrest date is known, especially because the portal says to enter the same date in Arrest Date and In Custody On to see subjects arrested on a specific date. If the person was sentenced to state prison, use IDOC. If the person is in federal custody, use BOP after designation or the jail phone line if the county is housing the person for USMS.

1. Open the official Zuercher Inmate Listings portal from the sheriff's site or by direct URL.
2. Search by Name, or combine Race, Sex, Arrest Date, Release Date, and In Custody On if the name is common.
3. For a known arrest day, enter the same date in Arrest Date and In Custody On, as the portal notice directs.
4. Review the row for mugshot, name, race, sex, age, arrest date, release date, and hold-reason text.
5. If no row appears, call 309-558-3436 or 309-558-3455, then check IDOC, BOP, ICE, or VINE if the person moved systems.

The visible portal layout supports the field-by-field search path and the public roster limits described in the search tables below.

Rock Island County Roster Search Fields

The Rock Island County inmate population roster uses a Zuercher interface with a small set of public filters. The active configuration shows Name, Race, Sex, Arrest Date, Release Date, and In Custody On. It does not expose Cell Block or Held For Agency as separate public filters in the captured Rock Island configuration, although hold-reason text can still show housing for another agency. The public setup also uses age rather than full date of birth.

What Rock Island Inmate Records Show

A public Rock Island County jail roster row is narrower than the internal booking record required by Illinois jail standards. Visible rows can include mugshot, name, race, sex, age, arrest date, release date, and expanded hold-reason text. The hold-reason row is where charge and warrant detail appears. Sample public rows showed charge type, Illinois statute citation, plain-language charge text, pending status, arrest date, bond or no-bond text, dollar amount, set-by-judge language, warrant type, issuing jurisdiction, and count language.

Note: Juvenile information is restricted by the portal configuration and should not be expected in public roster results.

Past Rock Island Inmate Records

Released or transferred people can be harder to find. The Zuercher portal includes Release Date and In Custody On filters, and the portal warning says a missing person may have been released or transferred. It does not publish a fixed retention window for released inmates or mugshots. For older booking records, jail records not shown online, or historical booking photos, the sheriff records and FOIA path is the proper fallback. The county FOIA directory lists Stacey Watson, Investigations Secretary, for sheriff FOIA at 309-558-3414, and the records section is reached through 309-794-1230.

Court records follow a different route. If the reader needs formal charges, case events, hearing history, or certified copies after a booking, the better channel is Judici, the Circuit Clerk's public terminal, or the clerk copy request process. The county FOIA directory notes the Circuit Clerk is exempt from FOIA, so court-file requests should not be routed as sheriff booking-record requests.

Rock Island Jail vs State Prison

Search errors often come from using the wrong custody system. A person arrested in Rock Island County starts in county jail custody if still held locally. A person sentenced to IDOC custody moves into the state prison system and may be listed at East Moline Correctional Center or another IDOC facility. A person held for a federal case may be physically in the county jail under USMS authority before later moving to BOP. Immigration detention uses ICE's separate locator and requires different identifying information.

Rock Island County Detention Facilities

Two facilities drive the local custody map. The county jail is the downtown booking and pretrial facility. East Moline Correctional Center is a state prison within the county's borders. The same person can move from the county jail to IDOC after sentencing, so facility type controls the search path.

• Rock Island County Jail / Rock Island County Correctional Center holds adult pretrial detainees, local-sentence detainees, people held for other agencies, USMS detainees, and short-term county arrestees.
• East Moline Correctional Center is an IDOC minimum-security adult male state prison for sentenced people in state custody.

First Appearance and Release Timing

The Zuercher roster page provides a rare local timing note. It says First Appearance Court is Monday through Friday at 1:00 p.m. and Saturday at 8:30 a.m., with exceptions for holiday weekends. It also says inmate releases are usually 2:00 p.m. to 4:00 p.m. after First Appearance Court on weekdays and 10:00 to 11:00 a.m. on Saturdays. The word "usually" matters because warrants, outside-agency holds, judge-set detention, release conditions, and holiday schedules can change custody timing.

Illinois pretrial law also changed the meaning of older local "bond" labels. The county Inmate Services page still has a Bond Payment section and names GovPayNet, while Illinois Article 110 abolished monetary bail for current pretrial release decisions. Roster text may still show "Bond," "No Bond," "$0.00," or "Set By Judge." Those are display labels and case notations, not a promise that a payment will release the person.

Visitation, Mail, and Money Basics

Rock Island County jail visitation depends on the detainee's cell-block schedule. Each inmate may have five adult visitors on the registration list, not including minors. Adults need valid photo identification. Minors must be with a parent or legal guardian. No more than four visitors may be in the visitation area at one time, and visits last 30 minutes. Because inmates can move, the county tells visitors to call 309-558-3455 to verify dates and times before traveling.

Personal inmate mail changed on July 1, 2024 through ViaPath Technologies and TextBehind. The county says letters, postcards, greeting cards, photographs, and drawings are scanned and delivered digitally through the tablet system, while legal mail and money orders go directly to the jail. The research found conflicting TextBehind P.O. box examples in county sources, so current mailing-address details should be verified with the jail before sending mail. Commissary slips and money must be paid by 8 p.m. Sunday for that week's order schedule, and iCare packages are available for Rock Island County commissary in Illinois.

Rock Island Jail Programs and Conditions

The county Inmate Services page lists behavioral health counselors, Narcotics Anonymous, Alcoholics Anonymous, GED, parenting classes, religious services, and trustee work. The 2024 IDOC inspection adds more operating detail: Robert Young Center provides mental health services, Advanced Correctional Healthcare provides medical care, GTL/ViaPath provides phones and tablets, LexisNexis provides a digital law library, and Aramark provides commissary items and meals prepared on site. The inspection also noted a family resources program and an on-site GED program through Black Hawk College.

Inspection and procurement records add useful context without changing the search path. A 2023 IDOC report cited training-documentation and supervision-check issues and recommended repainting detainee living areas. A 2024 report recorded detainee concerns and county responses on hot water and renovations. Separate 2025 county procurement files covered exterior waterproofing, inmate communications, food and commissary services, and swing-door lock replacement. These are facility-condition facts, not inmate-lookup records.
