Montgomery County Inmate Population Snapshot
The Montgomery County inmate population is not one single list. The main local count is the Montgomery County Jail population, which covers adult pretrial detainees, local sentenced inmates, people held on warrants, people waiting for court, and people waiting on transfer decisions. The sheriff's jail page points users to the public roster, which is branded Montgomery County Sheriff Rob Streck - Persons In Custody and lists the jail provider as MONT-JAIL. On June 24, 2026 around 11:30 a.m. Eastern, that roster showed 491 to 492 people in Montgomery County Jail custody and stated that the data updates every 30 minutes.
Other custody lanes sit beside that jail count. MonDay Community Correctional Institution is a court and community-corrections facility, not a normal jail roster population. Dayton Correctional Institution is an Ohio Department of Rehabilitation and Correction prison for sentenced state prisoners, so it is searched through ODRC rather than the county roster. Federal prisoners and immigration detainees use separate federal systems. That split matters because a person can start in the county jail after arrest, move through video arraignment or bond review, then leave the jail roster after release, sentence, transfer, or a hold from another agency.
Montgomery County Inmate Population Statistics
The strongest official statistics are point-in-time figures, not a full annual average daily population series. The 2024 ODRC annual jail inspection report listed Montgomery County Jail with a total actual general housing capacity of 903 and counted 602 inmates on the inspection date. The public roster snapshot on June 24, 2026 was lower, at 491 to 492 current detainees. Those two values describe different moments, so they should not be treated as the same metric.
| Measure | Figure | Source / Date |
|---|---|---|
| Montgomery County Jail roster count | 491-492 | Persons in Custody roster, June 24, 2026 around 11:30 a.m. |
| Roster update interval | 30 minutes | Persons in Custody provider table, June 24, 2026 |
| General housing capacity | 903 | ODRC annual jail inspection, 2024 |
| Inmates on inspection date | 602 | ODRC annual jail inspection, 2024 |
| Capacity use on inspection date | About 66.7% | 602 divided by 903 from ODRC 2024 data |
Montgomery County Inmate Population Trends
Recent official figures show a lower point-in-time jail population than earlier ODRC inspection counts. The 2019 ODRC inspection counted 796 inmates against the same 903 capacity. The 2021 inspection counted 664 inmates, and the 2024 inspection counted 602. The June 24, 2026 roster snapshot was lower still. That is a visible downward trend in the located official data, but the figures are not a full annual average. Inspection counts, roster counts, and annual averages are different ways to measure custody.
| Year / Date | Population or Count | Notes |
|---|---|---|
| 2019 inspection | 796 | ODRC annual jail inspection; capacity 903. |
| 2021 inspection | 664 | ODRC annual jail inspection; capacity 903. |
| 2024 inspection | 602 | ODRC annual jail inspection; capacity 903. |
| June 24, 2026 roster | 491-492 | Public roster provider table; updates every 30 minutes. |
Population can rise or fall because of arrests, weekend booking flow, bond decisions, municipal court schedules, felony charging decisions, transfers to ODRC, and releases after court action. Montgomery County also runs video arraignment from the jail for several courts, which keeps custody and court processing linked in the downtown Dayton jail and court system.
Montgomery County Jail Capacity
Montgomery County Jail is a large urban county jail with a rated general housing capacity just above 900 beds. The 2024 inspection count of 602 was below capacity by about 301 beds on that date. The 2019 inspection count of 796 was also below capacity, but it was much closer to the limit. A live roster count can look lower because it is a current custody snapshot rather than an inspection-day count. It can also change after the next booking cycle, release list, or transfer run.
The sources located for this build did not publish a reliable official breakdown by race, age, sex, felony or misdemeanor charge, pretrial or sentenced status, average length of stay, annual bookings, or holds for other agencies. Those gaps should be treated as missing official county data, not as an invitation to estimate. The public roster and ODRC inspections still give a defensible local picture of jail size, capacity, and recent point-in-time counts.
Data note: A roster count is not the same as an average daily population. Use the date and source label when comparing Montgomery County inmate population figures.
Montgomery County Inmate Population Laws
Ohio law shapes what can be viewed, requested, redacted, or withheld. The county roster gives current custody access, but it does not replace a formal public-records request, court docket search, or ODRC search. The sheriff's records page says public records maintained by the Sheriff's Office may be inspected or copied within a reasonable time. For offense and crash reports, the Records Section directs callers to wait at least three business days after the incident and call (937) 225-4096.
Key Ohio rules:
ORC 149.43 is the Ohio Public Records Act, with access rights and exemptions for some law-enforcement, medical, juvenile, victim, and restricted personal information.
ORC 5120.21 governs many ODRC inmate records and permits disclosure of items such as name, convictions, photograph, status, and incarceration location.
OAC Chapter 5120:1-8 supplies the minimum standards used for full-service jail inspection and jail operations.
ORC 341.05 requires the sheriff to assign sufficient staff for safe county jail operation.
Search the Montgomery County Inmate Population
The official starting point for a current local jail search is the Persons in Custody roster. The roster covers inmates currently held in the listed jail provider, which was MONT-JAIL for Montgomery County Jail during the research capture. It does not state that it searches other jails, state prisons, federal custody, or ICE custody. If a name does not appear, the next step depends on the timing and custody type. A very new arrest may still be in intake. A sentenced prisoner may have moved to ODRC. A released person may require a public-record request or court lookup.
The Montgomery County Persons in Custody roster image below shows the local roster's provider table and name-browse controls. It is the visual source for the population, phone number, update interval, and roster layout.
The provider table is useful even before a name search because it confirms the jail name, phone line, roster refresh rate, and current count.
- Open the sheriff's jail page and choose Inmates in Custody, or go directly to the Persons in Custody roster.
- Confirm the provider table lists MONT-JAIL and Montgomery County Jail before treating the result as a local jail search.
- Use the Search by Last Name A to Z links. The page may require a captcha or human-verification code.
- Review the current custody results and use Last or First controls if shown in the live session.
- If the person is not listed, call the Inmate Information Line at (937) 225-4160 or check ODRC, BOP, ICE, VINELink, or public-record channels as the custody path requires.
Montgomery County Roster Search Fields
The public roster is alphabet-driven. The captured roster homepage did not expose a normal free-text box for last name or first name. Instead, the public starts with A through Z links under Search by Last Name. A search request may route to a CheckCaptcha page, which says the user must prove human access and permit session cookies for the Miami Valley Jails site. That limitation is important for accuracy because automated browsing did not reach a sample inmate detail page.
| Field Label | Type | Required | Options / Notes |
|---|---|---|---|
| Search by Last Name | Alphabet link list | Yes for browse path | A through Z links by last-name initial. |
| Last | Sort/control link | Unspecified | Visible in the roster header. |
| First | Sort/control link | Unspecified | Visible in the roster header. |
| Link/button | No | Print option visible on the roster page. | |
| Help / FAQs / Who can I call? | Help links | No | Roster help and phone guidance. |
| Type the code shown | Captcha text input | Required after redirect | Appears after some search requests. |
Montgomery County Inmate Record Fields
The captured county roster homepage confirms visible provider and search data, but it does not confirm the full detainee profile fields because the detail path was blocked by human verification. That means Montgomery County inmate record content should be described conservatively. The roster is the official first lookup for current custody. For charges, court dates, bond events, and filed case documents, a reader should also use the clerk and court systems after the case opens.
| Visible Field | What It Shows |
|---|---|
| Roster title | Montgomery County Sheriff Rob Streck - Persons In Custody. |
| Search by Last Name | A to Z browsing links for last-name initial. |
| Jail provider code | MONT-JAIL. |
| Jail provider name | Montgomery County Jail. |
| Population | Current provider-table count, observed at 491 to 492 on June 24, 2026. |
| Phone | (937) 225-4160. |
| Update frequency | Every 30 minutes. |
| Captcha notice | Search may require human verification and session cookies. |
Montgomery County Jail vs Prison Search
County jail custody and state prison custody are different records systems. Montgomery County Jail is the local arrest and pretrial custody hub. ODRC is the state prison agency for people sentenced to state custody. A person can appear on the county roster after arrest, then disappear from it after release, transfer, or conveyance to state prison. Dayton Correctional Institution is located in Montgomery County, but it is still an ODRC facility and is not searched through the county jail roster.
| County Jail | State Prison | |
|---|---|---|
| Who is held | Pretrial detainees, local sentenced inmates, warrants, court holds, transfers. | Sentenced state prisoners and some supervision records. |
| Run by | Montgomery County Sheriff's Office. | Ohio Department of Rehabilitation and Correction. |
| Lookup | Persons in Custody roster. | ODRC Offender Search. |
| Best use | Recent arrest and current local custody. | Post-sentence prison location, ODRC number, status, and public conviction data. |
State and Federal Inmate Search
ODRC Offender Search is the correct statewide lookup for sentenced Ohio prisoners and parole-related records. Search fields include last name, first name, county of commitment, offender number, and status or institution filters. Montgomery appears as a county of commitment option. Under ORC 5120.21, ODRC may disclose name, criminal convictions, photograph, status, current or past incarceration location, and disciplinary history, even though the full prison file is not treated like an ordinary county public record.
Federal and immigration custody require different systems. The BOP Inmate Locator covers federal inmates from 1982 to present, mainly by register number or name. The ICE Online Detainee Locator System is the official public ICE detainee locator and generally uses an A-number with country of birth or biographical data. Ohio VINELink is useful for custody notification and status alerts. The official MoCoInfo app exists, but no app-only inmate roster was confirmed from the store text.
Montgomery County Detention Facilities
The resolved Montgomery County facility list has three separate roles. The county jail is the primary roster population. MonDay is community corrections and treatment. Dayton Correctional Institution is state prison custody. Keeping those lanes separate prevents a common search error: using the county roster for someone who has already moved to prison, or using ODRC for someone arrested in Dayton hours ago.
- Montgomery County Jail holds adult pretrial detainees, local sentenced inmates, warrant holds, and people waiting on bond, court, or transfer decisions.
- MonDay Community Correctional Institution is a secure community-based correctional facility for court-ordered treatment, accountability, and reentry programming.
- Dayton Correctional Institution is an ODRC state prison in Dayton for sentenced state prisoners, not current county jail detainees.
Montgomery County Booking and Jail Services
New jail bookings may not appear on the public roster until intake is complete and the roster refreshes. Intake includes custody entry, identity work, property handling, and booking steps. The jail medical page says Naphcare provides health services, with medical staff on duty 24 hours a day, seven days per week. Mental-health counselors are also available 24/7, and mental-health screening is documented as part of the booking process. That makes the public roster only one part of the intake path.
Bond information is also local and practical. The sheriff's inmate information page says bond may be posted 24 hours a day at the Inmate's Property Room Window in the jail lobby, and the bond amount should be checked at (937) 224-8447. Ohio House Bill 1 adds a bail surcharge that can be as much as $85 per bond, and the jail says personal checks cannot be accepted. If another court, probation, parole, federal, or ICE hold exists, local bond payment may not cause release.
