Darke County Inmate Population Snapshot
The Darke County inmate population is centered on one local detention site: the Darke County Correctional Facility in Greenville. The facility is run by the Darke County Sheriff's Office, which names Sheriff Mark Whittaker and links the public to the jail roster, jail page, annual reports, and public records. Official research found no separate county work-release building, jail annex, state prison, federal prison, or ICE detention center inside Darke County. That makes the local map simple, but not every inmate connected to a Darke County case remains in the county jail.
The local jail holds adults arrested in Greenville, Versailles, Arcanum, Ansonia, Bradford, Union City, and other Darke County communities. It may hold pretrial detainees, people arrested on warrants, sentenced misdemeanants, people waiting for transfer, and local holds. Once a felony defendant is sentenced to state prison, the lookup path moves from the county roster to the Ohio Department of Rehabilitation and Correction Offender Search. Federal prisoners and immigration detainees use separate BOP, U.S. Marshals, or ICE channels. Mixing those systems is the most common cause of failed searches.
Darke County Inmate Population Statistics
The most useful Darke County inmate population figures come from the ODRC annual jail inspection, the Miami Valley Jails roster provider table, Census population estimates, and 2025 local reporting about the aging jail. Each source measures a different thing. ODRC's inspection count is a point-in-time count. The roster count is a live snapshot. The sheriff's reported average daily population describes the burden across a year. Those figures should not be treated as interchangeable.
| Measure | Figure | Source / Date |
|---|---|---|
| Actual general housing capacity | 36 | ODRC 2025 jail inspection, inspected October 21, 2025 |
| Recommended housing capacity | 36 | ODRC 2025 jail inspection |
| Inspection-day population | 32 | ODRC 2025 jail inspection |
| Roster snapshot | 30 | Miami Valley Jails, June 24, 2026 at 10:31 a.m. |
| 2024 average daily population | More than 44 | March 2025 Dayton 24/7 Now and My County Link reporting |
| Darke County population estimate | 51,520 | U.S. Census QuickFacts, 2025 estimate |
A reader comparing these numbers should focus on the time period. The ODRC count showed the jail below capacity on inspection day, while the sheriff's 2024 average daily figure showed a yearlong load above the formal bed count. Local reporting said the county had to house extra inmates outside Darke County at an annual cost of about $134,000.
Darke County Inmate Population Trends
Darke County's trend story is not a straight line. ODRC inspection snippets and the 2025 inspection report show point-in-time counts near or below the 36-bed capacity in several years. The 2024 average daily population, however, was reported as more than 44. That annual measure explains why jail improvement planning became a county issue even though a single inspection snapshot did not show crowding on that day.
| Year or Date | Jail Population / ADP | Note |
|---|---|---|
| 2019 inspection | 33 | ODRC search-result snippet, secondary source because the full file did not open in research. |
| 2020 self-audit | 30 | ODRC search-result snippet also reported 36 total housing capacity. |
| 2022 inspection | 28 | ODRC search-result snippet. |
| 2024 average | More than 44 ADP | Local March 2025 reporting tied to the sheriff's grant discussion. |
| October 21, 2025 | 32 | ODRC inspection count. |
| June 24, 2026 | 30 | Miami Valley Jails roster provider table snapshot. |
Population context: If the 2024 ADP was more than 44 against a 36-bed capacity, the jail averaged at least eight people over capacity across that year.
Darke County Jail Capacity
The sheriff's jail page describes the Darke County Correctional Facility as a 36-bed, county-owned jail outside Greenville. The ODRC 2025 inspection recorded the same actual and recommended capacity. Local reporting adds why that small number matters. The jail opened in July 1983, operates 24 hours a day, and has been described by Sheriff Whittaker as an aging linear design with plumbing, HVAC, medical-space, mental-health, and programming-space concerns.
In March 2025, the county pursued a $200,000 state grant for a jail needs assessment. The reports said a modern design could potentially hold at least 80 people with nearly the same number of correctional staff, according to the sheriff. That does not mean a new jail has been built. It means the Darke County inmate population is tied to a facility-planning debate about capacity, safety, medical care, and costs for out-of-county housing.
Darke County Inmate Record Laws
Ohio law gives the public a path to basic jail and court information, but it does not turn every correctional file into an open database. Darke County inmate population data sits under public-records law, jail-register law, and statewide jail standards. State-prison records follow a separate ODRC statute. Booking photographs have their own Ohio law concern because commercial mugshot sites can misuse criminal-record information.
Key Ohio laws:
ORC 149.43 covers Ohio public records and the general right to inspect or copy non-exempt public office records.
ORC 341.02 requires the sheriff to keep a jail register with each prisoner's name, commitment date and cause, and discharge date and manner.
OAC Chapter 5120:1-8 sets standards for full-service jails, including reception, classification, housing, visitation, medical care, sanitation, and staffing.
ORC 5120.21 governs ODRC inmate records and permits release of listed state-prison information such as name, convictions, institution, status, and sentence data.
Search Darke County Jail Inmates
The official current-custody roster is the Miami Valley Jails Darke County roster. The sheriff's homepage and jail page both point users to it. The provider table uses code DARK-JAIL, lists the facility as Darke County Jail, gives the jail phone as 937-548-3399, and states that information updates every 30 minutes. The roster warns that it covers only inmates currently held in the jail or jails listed on that page, with no information for people housed elsewhere.
The roster interface is built around last-name browsing. It shows A through Z links for "Search by Last Name," Last and First result headings, a Print link, FAQs, and a "Who can I call?" link. A CAPTCHA may appear, and the security notice says automated programs are not permitted. If the roster blocks a session, use a normal browser with cookies enabled or call the jail.
- Open the sheriff's jail page or go directly to the Miami Valley Jails Darke County roster.
- Confirm the provider table shows DARK-JAIL / Darke County Jail.
- Check the update frequency and last-update time before relying on the count.
- Use the A-Z last-name links to browse current custody records.
- If the person is not listed, call the jail or switch to the records, ODRC, BOP, ICE, or VINE channels that fit the case.

The update table is important because a new booking or recent release may not appear until the next cycle.
Darke County Roster Search Fields
The public roster landing page exposes a narrow search interface. It does not act like a broad statewide name search, and automated research could not inspect individual profiles after the site's CAPTCHA. The verified fields are still useful for understanding what can be searched and what the provider table confirms.
| Field or Element | Type | Required | Notes |
|---|---|---|---|
| Search by Last Name | Alphabet-link filter | Optional | A through Z links are visible on the roster landing page. |
| Last | Result heading | Unspecified | Visible as a name-related heading. |
| First | Result heading | Unspecified | Visible as a name-related heading. |
| Type the code shown | CAPTCHA field | Required if shown | Appears when the site requests human verification. |
| Provider table | Facility status table | N/A | Shows code, jail name, population, phone, update cycle, and last update. |
Darke County Inmate Record Fields
For Darke County jail records, the verified public landing page shows the current-custody scope and provider details. Individual profile fields such as mugshot, booking number, bond, charges, housing unit, and arresting agency were not verified through automated inspection because the site required human CAPTCHA completion. That limitation should be taken seriously. If a custody or bond question turns on a field not visible on the landing page, call the jail or request records from the sheriff's records unit.
| Verified Field / Element | What It Shows |
|---|---|
| Page title | Darke County, Ohio, persons currently in custody. |
| Last / First | Name-related result headings or sort labels. |
| Provider code | DARK-JAIL for Darke County Jail. |
| Population | Dynamic current count, with a timestamp. |
| Update frequency | Thirty-minute update cycle. |
| Scope notice | Current custody in listed jail only, not other jails. |
Darke County Inmate Search Fallbacks
A current roster is the fastest channel, but it is not the only channel. Call the Darke County jail at 937-548-3399 when a new arrest may not have posted, a release may have just occurred, or the person might be housed elsewhere. The sheriff's non-emergency number is 937-548-2020. For report copies, use the sheriff's records department at 937-547-4603 or records@darkecountysheriff.org. The records page says copies are available Monday through Friday, 8 a.m. to 4 p.m., and requests may take 2 to 3 business days for a reply.
State and federal channels matter when the county roster does not fit. ODRC covers sentenced Ohio prisoners, released state offenders, APA supervision, and violators at large. Ohio VINE/VINELink provides custody status and notification. The BOP Inmate Locator covers federal inmates from 1982 to present. ICE custody uses the ICE Online Detainee Locator or the official USAGov ICE explanation. No released Darke County Sheriff jail app was verified in research; the Greenville Police Department app was not verified as a jail roster tool.
| Situation | Best Channel | Why |
|---|---|---|
| Current local custody | Miami Valley Jails Darke roster | It is the official current-custody source for the listed jail. |
| New arrest or uncertain release | Jail phone | Staff can confirm details not yet reflected in a roster refresh. |
| Past reports or booking records | Sheriff's Records Department | The current roster is not an archive. |
| Sentenced Ohio prison case | ODRC Offender Search | State-prison custody leaves the county roster path. |
| Federal or immigration custody | BOP, USMS, or ICE | Those systems are separate from Darke County jail records. |

Darke County Inmate Population FAQ
How large is the Darke County inmate population?
The answer depends on the source date. ODRC counted 32 people at the Darke County Correctional Facility on October 21, 2025. The Miami Valley Jails provider table showed 30 on June 24, 2026 at 10:31 a.m. Local 2025 reporting said the 2024 average daily population was more than 44.
Why can the jail be under capacity one day and over capacity for a year?
A point-in-time count is one snapshot. Average daily population spreads the custody load across a full period. Darke County's 36-bed capacity can look adequate on an inspection day but still be strained during high-booking months or when releases and transfers slow down.
How do I search the Darke County inmate population?
Start with the Miami Valley Jails roster for current custody. If the person is not listed, call the jail, use the sheriff's records department for older records, check ODRC for sentenced prison custody, and use BOP or ICE channels for federal or immigration custody.
Does the roster show past inmates?
The Darke County roster is current-custody focused. Released people may not stay visible. Past jail reports or booking records should be requested from the sheriff's records department, while court case documents should be requested from the appropriate court or clerk.
