The Clark County Inmate Population
The Clark County inmate population is reported through the Miami Valley Jails Clark County roster for people who are currently in the Clark County Jail. That roster is the official public custody page linked from the Clark County Jail page. It covers adults in local custody, such as new arrests, people waiting for arraignment, defendants held before trial, local sentenced inmates, and people held on warrants or local holds. It does not cover every person arrested in Clark County forever. A released person, a sentenced state prisoner, a federal inmate, or an immigration detainee may fall outside the county jail roster.
The count changes because arrests, court decisions, bond orders, warrants, releases, and transfers all affect the jail population. The Clark County Sheriff's Office operates the jail through its jail and court services function, while courts and prosecutors control charges, hearings, bond, and case outcomes. Once a felony defendant is sentenced to prison, the lookup usually moves from the county roster to the Ohio Department of Rehabilitation and Correction Offender Search. That separation matters. County jail records show local custody. ODRC records show prison custody and supervision.
Clark County Inmate Population Statistics
Clark County's official materials provide a stronger capacity picture than a long demographic file. The live roster showed 197 inmates on June 24, 2026 at 10:30 AM. The county's jail-history and current-conditions materials identify Ohio's recommended housing capacity as 167 inmates, while the state-recognized general-bed figure is 180. The 2024 ODRC annual inspection result reported 175 inmates on the inspection day. Those are point-in-time and capacity figures, not a published annual average daily population.

Clark County Inmate Population Trends
The trend line in the research is a facility-capacity story rather than a full annual bookings report. The current jail opened in 1980 after construction began in 1977. It was built after a federal court order required the older jail to close for substandard conditions, and Clark County housed inmates in other jurisdictions during the construction period. The building opened with 168 beds and 11 isolation or medical cells. In the early 2000s, 24 beds were added in common areas, which helps explain why bed count and recommended capacity do not match cleanly.
| Year / Date | Population or Capacity Figure | Local Meaning |
|---|---|---|
| 1977 | Construction began | Current jail project started after the prior jail was ordered closed. |
| 1980 | Jail opened | The facility cost $8.2 million and measured about 92,000 square feet. |
| Original design | 168 beds plus 11 isolation or medical cells | County history material describes the original jail layout. |
| Early 2000s | 24 added beds | Beds were added in inmate common areas. |
| 2024 inspection | 175 inmates | Inspection-day count was above the 167 recommended capacity. |
| June 24, 2026 | 197 inmates | Live roster snapshot was above both 167 and 180. |
Clark County Jail Capacity
Clark County's current jail count should be read with two capacity numbers in mind. The county materials and ODRC inspection reference use 167 as the recommended housing capacity based on living space and operational standards. The same research identifies 180 state-recognized general beds. The June 24, 2026 roster snapshot of 197 inmates was 30 above the recommended figure and 17 above the general-bed figure. That does not prove an annual average, but it does show why the Clark County inmate population is tied to overcrowding and jail-condition discussions.
Capacity note: Clark County did not publish a local demographic table or annual average daily population in the captured official pages, so those fields should not be guessed.
Laws for Clark County Inmate Records
Ohio law shapes what the public can inspect and what jail operators must document. ORC 149.43, Ohio's Public Records Act, is the main access law for public records unless a specific exemption applies. ORC 5120.10 requires the ODRC director to set minimum jail standards. Ohio Administrative Code Chapter 5120:1-8 covers full-service jail standards, including reception, release, security, housing, sanitation, and programs. These rules do not make every record public, but they explain why custody, capacity, and jail-operation records exist.
Key statutes:
ORC 149.43 gives broad access to public records kept by Ohio public offices, subject to exemptions.
OAC 5120:1-8-04 requires full-service jails to maintain housing-space and maximum-occupancy documentation.
Ohio OCJS death-in-custody reporting covers custody-death reporting under the federal reporting framework.
Clark County State Prison Lookup
No ODRC state prison was identified inside Clark County. That does not mean Clark County defendants never enter the state prison population. After a felony case moves through Common Pleas and a person is sentenced to prison, the person leaves the county jail system and is searched through the statewide ODRC locator. ODRC profiles can show a photo, offender number, institution, status, admission date, offense details, ORC section, docket, committing county, judge, sentence, parole eligibility, and release-related information when available.
| System | Who It Covers | Where to Search |
|---|---|---|
| Clark County Jail roster | Current local jail custody only | Miami Valley Jails Clark County roster |
| ODRC Offender Search | Ohio prison custody and DRC supervision | ODRC Offender Search |
| BOP Inmate Locator | Federal inmates from 1982 to present | BOP inmate locator |
| ICE Online Detainee Locator | People currently held by ICE | ICE locator |
Search Clark County Jail Inmates
The official roster is hosted on Miami Valley Jails and titled "Clark County, Ohio, Sheriff - Persons Currently In Custody." The provider row is CLAR-JAIL for Clark County Jail, and the visible roster table says the information updates every 30 minutes. The roster also warns that it contains information only for inmates currently in custody in the listed jail. If a person is housed in another jail, state prison, federal custody, or immigration custody, the Clark County jail roster is not the final answer.
- Open the official Clark County jail page and choose Current Inmates In Custody, or go directly to the roster.
- Confirm the provider row is CLAR-JAIL, Clark County Jail, before relying on the result.
- Use the alphabet links under Search by Last Name to choose the first letter of the last name.
- Complete the human-verification screen if it appears. The site may require session cookies.
- Review current custody results, then call the jail or use records requests if the profile does not show the detail needed.
- Search ODRC, BOP, ICE, or VINELink if the person is not in local Clark County jail custody.
The roster screenshot below comes from the official Miami Valley Jails Clark County roster, which shows the alphabet search and provider-level custody table.
The provider table is useful because it confirms the jail row, phone number, population snapshot, and update interval before a person-level search begins.
Clark County Current Inmate Lookup
The captured roster view exposes an alphabet search rather than a simple blank last-name box. Person-level profiles could not be inspected through automated access because the site uses a captcha. For that reason, Clark County pages should not claim exact local profile fields that were not verified. The safe reading is that the roster confirms current custody status and provider-level details, while jail staff and records requests remain the fallback for charges, bond, housing, booking photo, and report details not visible online.
| Field or Control | Type | Required | Notes |
|---|---|---|---|
| Search by Last Name | Alphabet link filter | Optional, primary navigation | A through Z links are visible. |
| Last / First | Navigation or sort label | Unspecified | Visible near the roster controls. |
| Type the code shown | Captcha text | Required after security check | Human verification appears before viewing current-custody pages. |
| Provider code and name | Provider table | Not a search field | CLAR-JAIL, Clark County Jail. |

Clark County Jail Records Channels
When the online roster is not enough, Clark County has several official access channels. The roster provider phone is 937-328-2560. Jail/Corrections is 937-521-2080. The sheriff's main office is 937-521-2050. Records requests and warrants are routed to Nikki Callahan at 937-521-2073, while report-copy requests can be made by phone at 937-521-2063. In-person records requests go through the Sheriff's Office lobby at 120 N. Fountain Avenue in Springfield, Monday through Friday, 8 a.m. to 4 p.m.
The Sheriff's records page says fax requests use 937-325-8321 and email requests may go to investigations@clarkcountyohio.gov. The request form itself lists Investigationscadet@clarkcountyohio.gov, so the research preserves that source difference rather than choosing one silently. The form asks for incident type, report number if known, people involved, incident location, date, time, requester identity, contact information, and the requester's interest in the matter. Fees include 10 cents per page, 10 cents per emailed photo, and listed media or video costs.
Clark County Detention Facilities
Clark County has one confirmed adult detention facility for this build. Municipal police agencies may make arrests, and federal or immigration authorities may control some people, but no separate ODRC prison, BOP prison, ICE detention facility, sheriff annex, or work-release center was identified inside Clark County from the official facility research.
- Clark County Jail holds adults in local Clark County custody, including new arrests, pretrial detainees, local sentenced inmates, and people held on warrants or local holds.
The Clark County Sheriff page identifies Sheriff Christopher D. Clark and places jail and court services within the sheriff's operating structure.
That office context matters because the sheriff operates the county jail, while the courts and prosecutor control the criminal case record after arrest.
