How to Look Up St. Charles County Jail Population Data
St. Charles County does not publish a single live population dashboard on the county site. The current count comes from the county Department of Corrections, while the trend context comes from national and state research sources. The Corrections page sits at sccmo.org/183/Department-of-Corrections. For figures the county has not posted, the federal Bureau of Justice Statistics and the Prison Policy Initiative Missouri profile are the standard public sources.
The most reliable county number comes straight from the Department of Corrections by phone. Research databases publish state and national rates that put the county in context but lag the live count by months or years. This page keeps the two layers separate so the county-specific facts are never mixed with statewide or national estimates.

The BJS site at bjs.ojp.gov publishes the national jail population reports used to frame St. Charles County inmate population trends.
Use the county Corrections office for the live St. Charles County jail count and BJS for the national benchmark.
St. Charles County Jail Capacity Overview
The St. Charles County Department of Corrections operates the county jail in downtown St. Charles. The facility holds pretrial detainees, people serving short local sentences, warrant holds, and people awaiting transfer to the Missouri Department of Corrections. The table below lists the facility detail confirmed for the county.
| Facility | Address | Official Page |
|---|---|---|
| St. Charles County Department of Corrections | 301 North Second Street, St. Charles, MO 63301 | sccmo.org/183/Department-of-Corrections |
The county did not publish a current rated bed capacity on its public pages during the most recent review. For a verified capacity figure, contact the Department of Corrections directly rather than relying on a third-party estimate.
Average Daily Population
Average daily population, often shortened to ADP, is the mean number of people held in a jail across a measurement period. It smooths out the daily swings caused by weekend arrests, court dockets, and release events. ADP is the number most often used to compare a jail across years.
The county has not posted a current ADP figure on its public pages. County budget documents and annual reports are the usual place a Missouri county publishes ADP, so a public records request or a review of the county budget on sccmo.org is the right path for a verified local number. National ADP context comes from the Bureau of Justice Statistics.
Note: A single-day jail count and the average daily population are different measures, and mixing them produces misleading comparisons.
Pretrial vs. Sentenced Population
County jails hold two broad groups. Pretrial detainees have been charged but not convicted in the pending case. Sentenced detainees are serving a local sentence or waiting for transfer to state prison. The mix matters because pretrial detainees are presumed innocent and many are held only because they cannot post bond.
| Group | Status | Typical Reason Held |
|---|---|---|
| Pretrial detainees | Not convicted in pending case | Bond not posted, hold, or detention order |
| Sentenced (local) | Convicted, short sentence | Serving a county jail sentence |
| Awaiting transfer | Sentenced to state prison | Waiting for Missouri DOC intake |
| Holds | Varies | Warrant holds, federal or other-county holds |
Nationally, a large share of county jail populations are pretrial rather than sentenced. The exact St. Charles County split is not published online; the Department of Corrections is the source for a current local breakdown.
Demographic Breakdown
Jail demographic data covers age, sex, race, and charge category. St. Charles County does not publish a current demographic breakdown of its jail on its public pages, so the reliable local source is a public records request to the Department of Corrections or a county budget or annual report.
The Prison Policy Initiative publishes a Missouri profile that breaks down incarceration by race and category at the state level. The Missouri profile is useful for state context, but its numbers are statewide rather than county-specific. Treat any demographic figure as state or national context unless it comes straight from St. Charles County Corrections.

The Missouri profile at prisonpolicy.org/profiles/MO shows statewide incarceration breakdowns that frame St. Charles County jail demographics.
Use the Missouri profile for state-level demographic context and the county Corrections office for any county-specific figure.
Misdemeanor vs. Felony Population
The charge mix in a county jail shifts the population profile. Felony holds tend to stay longer, especially when the case is pretrial or the person is awaiting transfer to state prison after sentencing. Misdemeanor and ordinance holds tend to move through faster.
St. Charles County felony cases run through the Criminal Division of the 11th Judicial Circuit Court, while many misdemeanor and traffic matters route through associate circuit and municipal dockets. A felony sentence to state prison eventually moves the person out of the county jail and into the Missouri Department of Corrections. The county jail count therefore reflects local pretrial and short-sentence work more than long-term incarceration.
Mental Health and Medical Population
A share of any county jail population needs mental-health or medical care. Jails handle intake screening, ongoing medication, and crisis response, and a portion of detainees wait for competency evaluation or treatment placement. These needs affect staffing and bed use even when the raw count is stable.
St. Charles County does not publish a mental-health population breakdown on its public pages. National research from the Bureau of Justice Statistics documents the broad scale of mental-health needs in jails, which provides context for the county without standing in for a local figure.
National and State Context
St. Charles County jail data is easier to read against a benchmark. The comparison below frames county jail use against the state and national rate per 100,000 residents. The county-specific rate is not published online, so the table marks which figures are local versus context.
| Level | Source | Figure Type |
|---|---|---|
| St. Charles County | Department of Corrections | Local count (request from county) |
| Missouri | Prison Policy Initiative | State incarceration rate |
| National | Bureau of Justice Statistics | National jail rate per 100,000 |
The Vera Institute also tracks county-level incarceration trends nationally, although its St. Charles County dataset was not reachable during the most recent review. When it is available, county trend data is a useful cross-check against the BJS national rate.
Population Trends Over Time
Jail populations move with arrest patterns, court speed, bond practice, and state transfer timing. The years after 2020 saw national jail counts dip and then climb back toward earlier levels as courts cleared pandemic backlogs. St. Charles County's own year-by-year figures are best pulled from county budget and annual documents on sccmo.org, since the county has not posted a public trend table.
To build a verified St. Charles County trend, the practical path is to gather the corrections budget or annual report for each year and to cross-check against BJS national figures and any Vera county trend that becomes available. Avoid treating a single-day count as a trend point; ADP across a full year is the better comparison unit.
Searching for St. Charles County Inmate Records by Name
This page covers population data rather than individual records. To look up a specific person in custody, use the inmate records page, which walks through the county jail roster, VINELink, the Missouri DOC offender search, and the federal BOP locator. Population figures and individual-inmate lookups are separate tasks with separate tools.
Where the St. Charles County Data Comes From
The county-specific facts on this page come from the St. Charles County Department of Corrections and the county government site. The state and national context comes from the Bureau of Justice Statistics, the Prison Policy Initiative, and the Vera Institute. Court-side context for charges and sentencing comes from the 11th Judicial Circuit Court and court records.
