The Knox County Inmate Population
The Knox County inmate population is centered on one local detention facility: the Knox County Jail in Mount Vernon. Official county and ODRC sources did not identify a separate long-term city jail, county annex, work-release building, federal prison, ICE detention center, or state prison inside Knox County. The Knox County Sheriff's Office runs the jail, and the current sheriff identified in the 2025 ODRC inspection and county command-staff material is Sheriff Daniel J. Weckesser. That local custody role matters because the sheriff roster is not a full criminal-history database. It is a current county jail custody report.
The jail population changes when people are arrested, booked, released on bond, sentenced locally, held for another county, or moved to state prison. Sheriff's annual reports say the Knox County Jail houses adults awaiting trial on misdemeanor or felony charges, people serving misdemeanor or certain felony sentences, felony prisoners waiting for prison transport, and federally charged inmates housed by contract with the U.S. Marshals Service. Once a Knox County defendant is received by the Ohio Department of Rehabilitation and Correction, the search path changes to the statewide ODRC Offender Search.
Knox County Inmate Population Statistics
The strongest Knox County inmate population figures come from the sheriff's annual reports and the ODRC annual jail inspection. The 2025 ODRC inspection reported a recommended and actual general housing capacity of 100. That inspection counted 90 inmates at the jail on November 18, 2025. The 2024 sheriff annual report listed an average daily jail population of 78 and 1,182 total prisoners housed or booked during the year. The official PDF jail roster reviewed for research was printed June 24, 2026 and showed 79 total records.
| Measure | Figure | Source / Year |

| Recommended/general housing capacity | 100 | ODRC annual jail inspection, inspected 11/18/2025 |
| Inspection-day population | 90 | ODRC annual jail inspection, 11/18/2025 |

Knox County Inmate Population Trends
The multi-year figures show that Knox County jail bookings are still far below the 2018 and 2019 totals, while the average daily population has moved back near pre-2020 levels. The 2024 report listed 78 average daily inmates, lower than 82 in 2023 but higher than the 2021 and 2022 low points. Total prisoners housed rose from 1,114 in 2022 to 1,139 in 2023 and 1,182 in 2024. That means the jail handled more booked people in 2024 while holding a slightly smaller average daily count than in 2023.
| Year | Average Daily Population | Total Prisoners Housed | Notes |
|---|---|---|---|
| 2018 | 82 | 2,070 | Higher pre-2020 booking volume. |
| 2019 | 88 | 1,979 | Highest ADP in the sheriff trend. |
| 2020 | 73 | 1,349 | Large pandemic-era drop. |
| 2021 | 68 | 1,142 | Lowest ADP in the available table. |
| 2022 | 69 | 1,114 | Booking count continued near the low point. |
| 2023 | 82 | 1,139 | ADP rose back to the 2018 level. |
| 2024 | 78 | 1,182 | Bookings rose while ADP fell from 2023. |
Who Makes Up the Knox County Inmate Population
The 2024 sheriff report gave age and sex booking counts, but it did not publish every breakdown readers often ask for. It did not locate an official Knox County split by race, average length of stay, felony versus misdemeanor status, pretrial versus sentenced status, ICE detainer count, or annual deaths in custody. The local facts that are published are still useful. The 2024 report counted 898 male prisoners housed and 284 female prisoners housed, roughly a 76 percent to 24 percent split. The 35 to 44 age group was the largest booking group in 2024, followed by ages 25 to 34.
| 2024 Age Group | Male Bookings | Female Bookings |
|---|---|---|
| 18-24 | 112 | 22 |
| 25-34 | 235 | 84 |
| 35-44 | 286 | 97 |
| 45-54 | 171 | 46 |
| 55-64 | 76 | 30 |
| 65 and older | 18 | 5 |
Knox County Jail Capacity
The 2025 inspection-day count of 90 inmates was below the recommended capacity of 100, and the 2024 average daily population of 78 was also below that capacity. That should not be read as a full conditions clearance. The same ODRC inspection reported compliance with 170 standards but listed five noncompliant standards, including one essential standard. The listed issues involved classification policy components, culinary equipment inventory practice, repair and maintenance items, fire-drill timing or documentation, and inmate grievance appeal language in the rules of conduct handbook.
The sheriff's annual reports add useful context. The 2023 report said a jail remodeling project meant to increase female housing had been completed and that the jail could house up to 24 female inmates. The 2024 report described TeamHealth medical care, Freedom Center substance-use services, and the hiring of a full-time correctional social worker. Those details are part of the Knox County inmate population picture because jail use is not just a count. It also depends on classification, health care, programs, transport, and release decisions.
Laws for Knox County Jail Data
Ohio law controls public access, jail standards, and the sheriff's duty to keep prisoners committed to the county jail. ORC 149.43, the Ohio Public Records Act, is the baseline for public records held by public offices, while also listing exemptions for confidential law-enforcement investigatory records, protected medical information, juvenile or sealed material, and certain image-related records. That is why Knox County jail records can be public while some details are withheld or redacted.
Key Knox County jail authorities:
ORC 341.12 requires the sheriff to receive and keep prisoners committed to the county jail by lawful authority.
ORC 5120.10 gives ODRC authority to set minimum jail standards and inspect local jails.
OAC Chapter 5120:1-8 sets full-service jail standards covering housing, classification, security, visitation, medical care, and grievances.
ORC 2929.37 and ORC 2929.38 support jail reimbursement and confinement-cost collection.
Knox County State Prison Searches
No state prison was found inside Knox County in the ODRC facility sources reviewed. A person sentenced from Knox County can still appear in the statewide ODRC system under County of Commitment as Knox. That record may list an institution, status, photo, docket, offense, ORC section, sentence dates, jail-time credit, judge, and victim-information labels. It is a deeper sentence record than the sheriff PDF, but it applies to state prison custody or ODRC supervision, not the current county jail population.
The State of Ohio Offender Search resource page and the Ohio Department of Rehabilitation and Correction are the official statewide paths. VINELink can add notification features, while the county roster remains the first check for local jail custody.
Search Knox County Jail Inmates
The official Knox County jail roster is a PDF report linked from the sheriff page as the Jail Inmate List. The direct roster URL is the sheriff's current inmate list PDF. The PDF reviewed for research was titled Website Inmate Info and printed June 24, 2026. It had 27 pages and 79 total records. It is not an interactive database, so a Knox County jail roster search usually means opening the PDF and using the browser or PDF viewer find tool.
- Open the current Knox County Jail inmate list from the sheriff page or direct PDF link.
- Check the print date before relying on the custody list.
- Use PDF find for a last name, then read nearby rows carefully.
- Compare the arrest date, hold reason, and listed charges before assuming a final court charge.
- If the name is missing, call the jail, contact sheriff records, search court portals, and check ODRC, BOP, ICE, or VINELink as the facts require.
Current Knox County Inmate Lookup
The Knox County inmate lookup process has a local quirk: the county publishes a current custody report, not a search form. The public PDF has no login, no reset button, no dropdown, no booking-number field, no release-date tab, and no profile page. The report header identifies a front mugshot column, name, arrest date, hold reasons, and charges for all hold reasons. The roster can show people held for other counties, people serving short local sentences, probation or warrant holds, and local charges. It does not show every field a court clerk or jail records unit may have.
| Roster Field | Type | Required | Notes |
|---|---|---|---|
| Front Mugshot | PDF image column | n/a | Report layout includes a front booking photo column. |
| Last, First Middle Name Initial | PDF text field | n/a | Names appear last-name first, often with middle name or initial. |
| Arrest | PDF date field | n/a | Dates use MM/DD/YY format. |
| Hold Reasons | PDF text field | n/a | Examples include charge, sentenced, held for another county, and warrant-related holds. |
| Charges | PDF text field | n/a | Charge lines can include ORC sections and count notes. |
| Total Records | PDF footer/count | n/a | The reviewed PDF showed 79 records. |
Past Knox County Inmate Records
No official retention rule for released inmates on the PDF roster was located. If a person is no longer listed, use the Knox County Sheriff's Office records channel rather than assuming the arrest did not happen. The records page names Records Clerk Karen Hall and lists records contacts at records@knoxcountysheriff.com and khall@knoxcountysheriff.com. The records clerk phone is (740) 399-3904. Emailed copies are not charged, while paper and media copies follow the posted fee schedule.
For a broader path, check the court case portals after a jail arrest. Municipal cases are commonly searched through Mount Vernon Municipal Court, felony cases through the Knox County Common Pleas Clerk, and limited juvenile records through Probate/Juvenile Court. A current custody record, a court charge, and a criminal history are different records. The Knox County jail inmate records page explains the roster fields in more detail.
Knox County Inmate Record Fields
A Knox County roster row is useful for a fast custody check, but it is not a full booking profile. It can show a front mugshot slot, name, arrest date, hold reason, and charge lines. The text-reviewed roster did not expose booking number, bond amount, housing unit, court date, warrant number, release date, full date of birth, full booking time, or physical descriptors. When those details matter, the practical route is to call the jail or use sheriff records and the court docket.
| Field | What It Shows |
|---|---|
| Front Mugshot | Booking-photo column in the public report layout. |
| Name | Last, first, and middle name or initial format. |
| Arrest Date | Date tied to the listed arrest or booking. |
| Hold Reason | Charge, sentence, out-of-county hold, warrant, failure to appear, probation, or parole-type reason. |
| Charges | ORC code and offense description, sometimes with counts. |
| Total Records | Count of rows in the PDF at print time. |
County Jail vs State Prison
Most lookup errors come from searching the wrong system. Knox County Jail is the local jail for pretrial detainees, short local sentences, sentenced felony prisoners awaiting transport, and some USMS contract detainees. ODRC is the state prison and supervision system. BOP is for federal sentenced inmates from 1982 to present. ICE ODLS is for immigration detention. VINELink is a notification tool, not a substitute for the jail or court record.
| Custody Type | Who Runs It | Where to Search |
|---|---|---|
| Knox County jail custody | Knox County Sheriff's Office | Current sheriff PDF roster and jail phone line. |
| Ohio prison or ODRC supervision | Ohio Department of Rehabilitation and Correction | ODRC Offender Search. |
| Federal sentenced custody | Federal Bureau of Prisons | BOP Inmate Locator. |
| Immigration detention | U.S. Immigration and Customs Enforcement | ICE Online Detainee Locator System. |
| Victim notification | VINELink and participating agencies | VINELink. |
Knox County Detention Facility
The facility map resolves one Knox County detention page. Mount Vernon Police and other municipal agencies make arrests, but the research did not locate a separate long-term municipal jail for adult detainees. The county jail is the official local custody destination for adult jail bookings, local commitments, and the public PDF inmate list.
- Knox County Jail - full-service county jail for adults awaiting trial, serving local sentences, awaiting prison transport, or held under U.S. Marshals contract.
Knox County Inmate Population FAQ
How big is the Knox County inmate population?
The 2024 sheriff annual report listed an average daily jail population of 78. The 2025 ODRC inspection counted 90 inmates at the Knox County Jail on November 18, 2025, against a recommended/general capacity of 100.

How do I search the Knox County inmate population?
Start with the official Knox County Jail inmate list PDF. Use the PDF find tool for a last name and read the print date, arrest date, hold reason, and charges. If the person is not listed, call the jail, contact sheriff records, search the court portals, and check ODRC, BOP, ICE, or VINELink as needed.
Does Knox County publish jail mugshots?
The current PDF roster layout includes a Front Mugshot column. The county did not publish a separate official recent-bookings gallery or historical mugshot archive in the sources reviewed. Booking-photo access is covered more fully on the Knox County jail mugshots page.
Who should be searched in ODRC?
Search ODRC when a Knox County defendant has been sentenced to state prison, placed under ODRC supervision, judicially released, or listed as a violator at large. A state prison record is not the same as the Knox County jail roster.
