The Missouri Inmate Population
The phrase Missouri inmate population can mean more than one record set. The most precise statewide prison figure in the research is the Missouri Department of Corrections count: the official FY25 profile reports 24,454 institutional offenders on June 30, 2025. That is the state-prison population, not the combined count of every person held in a county jail on that day. County jails are run locally and can change by the hour as arrests, releases, bond orders, court transports, and transfers occur.
Missouri is covered county by county in this build, including all 114 counties plus St. Louis City. That matters because the local jail layer is not one statewide database. Each sheriff, city jail, regional jail, or detention center may publish a separate roster or may require a call or records request. MODOC is the statewide system for sentenced state prisoners, probationers, parolees, conditional releases, transition centers, and community supervision. A person can move from one layer to another after sentencing or transfer, so the best search path depends on custody type.
The official Missouri Department of Corrections home page is the state source for MODOC context, including agency navigation and public links.
The MODOC home page helps separate state prison and supervision records from county jail bookings, which are searched through county-level sources.
Missouri Inmate Population Statistics
The strongest statewide statistic is the official MODOC institutional count. The FY25 offender profile reports 24,454 people in institutions on June 30, 2025, made up of 22,342 male offenders and 2,112 female offenders. The same report breaks the prison population down by race and ethnicity: 15,360 White offenders, 8,205 Black offenders, 676 Hispanic offenders, 110 Native American offenders, 49 Asian offenders, and 54 with unknown race or ethnicity.
Those figures should not be blended with county jail populations without a separate statewide jail census source. The research did not provide one combined county-jail average daily population figure for Missouri, so this page does not invent it. Instead, it treats the statewide prison figure as the official MODOC count and routes local jail searches to the county directory. The statewide facility directory is broad because it includes county jails, municipal holding units, state prisons, juvenile entries where the research found them, transition facilities, the federal medical center in Springfield, and ICE-relevant local detention notes.
| Measure | Figure | Source / Date |
|---|---|---|
| MODOC institutional offenders | 24,454 | FY25 offender profile, June 30, 2025 |
| Female institutional offenders | 2,112 | FY25 offender profile, June 30, 2025 |
| Male institutional offenders | 22,342 | FY25 offender profile, June 30, 2025 |
| Locality folders in the Missouri roll-up | 115 | Research aggregation, July 6, 2026 |
Missouri Inmate Population Trends
The official five-year trend is modest. MODOC's FY25 profile compares June 30, 2020 with June 30, 2025 and reports that the institutional population rose from 24,010 to 24,454, a 1.8 percent increase. The same profile reports a 3.1 percent increase in female population and a 1.7 percent increase in male population across the same span. It also reports that average sentence length decreased 3.0 percent.
Offense-group trends moved in different directions. Nonviolent offenses increased 17.2 percent, violent offenses increased 0.9 percent, sex and child-abuse offenses decreased 2.2 percent, drug offenses decreased 6.6 percent, and DWI decreased 11.5 percent. That mix is important for a Missouri inmate population page because a flat or small total change can hide shifts in the kinds of sentences people are serving.
| Comparison | Population / Change | Official Note |
|---|---|---|
| FY2020 institutional population | 24,010 | Base year in FY25 five-year comparison |
| FY2025 institutional population | 24,454 | June 30, 2025 count |
| Five-year total change | 1.8% increase | MODOC FY25 profile |
| Average sentence length | 3.0% decrease | MODOC FY25 profile |
The MODOC publications page is the official route to the FY25 offender profile and related reports.
Using the publications page keeps population claims tied to the state's own reports instead of to copied or stale summaries.
Who Is in Missouri Custody
MODOC uses the most serious sentence to group institutional offenders. On June 30, 2025, the prison population included 10,829 people in the violent offense group, 4,608 in sex or child-abuse offenses, 5,114 in nonviolent offenses, 3,455 in drug offenses, and 448 in DWI offenses. The total average sentence was 14.2 years, with male offenders averaging 14.6 years and female offenders averaging 10.5 years.
County jail populations are different. A county roster may include people waiting for first appearance, people held on bond, short-sentence inmates, probation or parole holds, city detainees, contract detainees, or people waiting on transport. A jail roster charge is not a conviction. Filed charges and court dispositions must be checked through Missouri Case.net or the circuit clerk.
- Pretrial custody
- A person held before case disposition, often in the county jail that booked the arrest.
- Detainer
- A hold from another agency, such as another county, parole authority, federal agency, or immigration office.
- Conditional release
- A Missouri sentence-release status governed by statute and supervision rules, not a simple jail release date.
Missouri State Prison System
MODOC states that it manages 21 correctional centers, 19 for men and two for women. The adult-institution address listing visible during research listed 19 adult institutions with acronyms, names, security levels, locations, addresses, and phone numbers. The research preserves that distinction: cite MODOC's facilities page for the 21-center count, and cite the address listing only for the named institutions it shows.
Security levels are numeric. Level 1 means minimum security, level 2 means medium security, and level 5 means maximum security. Several Missouri prisons have more than one level. Eastern Reception, Diagnostic and Correctional Center, Potosi Correctional Center, South Central Correctional Center, Southeast Correctional Center, Chillicothe Correctional Center, and Women's Eastern Reception, Diagnostic and Correctional Center each show multiple security levels in the research.
The MODOC facilities overview states the correctional-center count, custody levels, probation and parole office framework, and visiting overview.
That statewide facilities page is the right source when a Missouri inmate search turns from a county jail booking into a state-prison placement.
Laws for Missouri Inmate Records
Missouri's public-records framework is Chapter 610, known as the Sunshine Law. The Attorney General says a public-record request should go to the public body that created or keeps the record. That rule is practical for inmate records. MODOC records go to MODOC. County booking sheets, jail logs, and arrest reports go to the sheriff, jail, police department, or local custodian. Court filings go to Case.net or the circuit clerk.
RSMo 610.023 requires each public governmental body to have a custodian and says public-record requests must be acted on as soon as possible and no later than the end of the third business day after receipt. RSMo 610.100 defines arrest reports and incident reports and states that those reports are open records, while investigative reports and some sensitive material can be closed or limited.
Key Missouri statutes:
RSMo 610.011 states Missouri's open-records public policy.
RSMo 610.023 sets custodian and response duties for public-record requests.
RSMo 610.100 defines arrest and incident reports and explains major law-enforcement record limits.
The Missouri Attorney General Sunshine Law page gives statewide request guidance for public records.
The Sunshine Law guidance supports a key search rule: send the request to the office that made or keeps the record.
How to Search Missouri Inmates
A Missouri inmate population search works best as a decision tree. Start with the type of custody, then choose the portal. If the person was just arrested, search the county jail roster for the booking county. If the person has a state sentence, parole, probation, conditional release, or transition-center status, search MODOC. If the case is federal, use BOP. If the person is in immigration custody, use ICE ODLS and the known facility if available. If the question is about filed charges after an arrest, use Case.net.
- Search the MODOC Offender Search for active Missouri Department of Corrections supervision.
- Use the Missouri county directory for recent jail bookings and county rosters.
- Use the BOP inmate locator for federal inmates from 1982 forward.
- Use ICE ODLS for immigration custody, then contact the facility if the locator does not find the person.
- Use VINELink or MOVANS for custody notification where the participating agency feed supports it.

Missouri Jail vs Prison Search
County jail and state prison searches answer different questions. A county jail roster is best for a recent arrest, bond status, booking photo, booking number, or local hold. MODOC is best after a state sentence or for active probation, parole, conditional release, and supervision status. BOP and ICE are separate from both. MOVANS and VINELink support notification, but they do not replace the official roster, locator, court record, or custodian response.
| Custody layer | Who runs it | Where to search |
|---|---|---|
| County jail or city holding | County sheriff or city police | Local roster through the county directory |
| State prison or supervision | Missouri Department of Corrections | MODOC Offender Search |
| Federal prison | Federal Bureau of Prisons | BOP inmate locator |
| Immigration detention | ICE | ICE Online Detainee Locator System |
| Court charges after arrest | Missouri courts and circuit clerks | Case.net or the clerk |
Missouri Federal and Notification Search
The Missouri roll-up includes Medical Center for Federal Prisoners Springfield in Greene County. Federal prisoners should be searched through BOP, not MODOC and not a county roster unless the person is temporarily held locally. BOP supports search by register number, DCDC number, FBI number, INS number, or name fields, and its results can show release date and location. BOP also warns that First Step Act sentence review can affect release-date accuracy.
Missouri also uses VINELink and MOVANS for victim and custody notification. These tools help users search for participating custody records and register for alerts. They are not the final legal docket and do not prove a conviction. Court status still belongs with Case.net or the circuit clerk, and jail custody status still belongs with the roster or facility.
The Federal Bureau of Prisons inmate locator is the official federal search path for people in BOP custody.
BOP is separate from both Missouri county jails and MODOC, even when the facility is physically located in Missouri.
The Missouri VINELink portal supports custody-notification searches for participating records.
VINELink is useful for alerts, but official status should still be verified with the holding agency or court.
Missouri Detention Facilities
Missouri detention facilities include county jails, regional jails, city police holding units, MODOC prisons, diagnostic centers, transition centers, supervision centers, juvenile detention entries, and the federal medical center in Springfield. The statewide facility directory is an A-Z routing page, not a deep profile for each row. It distinguishes county jail rows from state prisons and federal or ICE-relevant entries because the search route changes with the type of custody.
The MODOC adult institution address listing provides facility acronyms, names, security levels, addresses, and phone numbers for the listed adult institutions.
State-prison rows in the facility directory should be read through the MODOC lens, not as sheriff-run jail rosters.
Missouri Inmate Population FAQ
How big is the Missouri inmate population?
The official statewide prison count in the research is 24,454 MODOC institutional offenders on June 30, 2025. That number is not a full statewide jail census. County jail populations are held and reported locally, so a current jail search should start with the county that booked or holds the person.
How do I find which county jail holds someone?
Start with the booking county, arresting agency, court county, or last known facility. Then use the Missouri county directory to reach that county's jail roster or local inmate-population site. If the person has been sentenced to state prison, switch to MODOC Offender Search.
Does MODOC show every Missouri inmate?
No. MODOC covers active Missouri Department of Corrections supervision and state custody. It does not replace county jail rosters, BOP, ICE, Case.net, or local records requests. It also does not show discharged offenders and may suppress some records for safety, security, or confidentiality.
