Inmate Population in St Louis County MO reflects a complex mix of pretrial detainees, sentenced individuals, and transfer cases that together shape the daily census reported by Justice Services. The St Louis County MO inmate population count is updated each morning, showing a current inmate population of roughly eight hundred‑plus persons, while the St Louis County MO jail population count tracks a similar range of occupied beds across the 1,578‑bed facility. Daily inmate population reports break down custody status, highlighting pretrial, sentenced, and transfer categories, and reveal occupancy rates that hover near ninety percent of total jail capacity. These inmate population statistics are published on the county’s public portal, allowing researchers, policymakers, and community members to examine trends such as fluctuations in the St Louis County MO detention population during court holidays or periods of heightened law‑enforcement activity. By integrating demographic data, gender breakdowns, and age cohorts, the St Louis County MO inmate statistics provide a granular view that supports evidence‑based decision making and resource allocation within the correctional system.
Inmate Population data for St Louis County MO is compiled through a daily reporting cycle that timestamps each entry with a precise population reporting date, ensuring transparency for stakeholders monitoring the current jail population. The St Louis County MO jail statistics include total jail population figures, inmate population by facility, and a breakdown of inmates by custody level, which together illuminate how many beds are occupied versus available capacity. For example, the St Louis County MO jail occupancy metric often shows an occupied‑bed count of around 780 to 820, leaving a modest buffer of unfilled beds that can be leveraged during surge periods. Monthly inmate population reports aggregate these daily snapshots, offering a longer‑term perspective on trends such as rising or declining admission rates, release volumes, and transfer movements. Adjacent to the raw counts, the St Louis County MO inmate population report also presents demographic snapshots, highlighting gender ratios and age distributions that inform program planning. By publishing these inmate population statistics alongside jail capacity data, the Justice Center equips officials with the insight needed to balance safety, rehabilitation, and fiscal responsibility.
How to Search Inmate Population
You can review the current Inmate Population figures for St Louis County MO through the official Justice Services portal operated by the St. Louis County Police Department. Residents can also access official booking reports to verify current details. The portal lists daily counts from the county detention center and shows them in a clear format that mirrors the morning jail roster snapshot. Because the data refreshes each day, you see the most recent headcount before staff process new admissions or releases later in the shift.
The search experience supports both quick overviews and detailed breakdowns. You can view the total Inmate Population, drill into facility-level counts, and check custody categories without creating an account or paying a fee. The portal also links to booking records, court dates, and release notices so you can match an Inmate Population count to an individual case.

Current Inmate Population
The current Inmate Population at the St Louis County MO Justice Center reflects the total number of persons housed in the detention facility at a specific reporting time. Justice Services refreshes this figure each morning before court hearings begin, giving you a reliable count of how many people are in custody right now. The number changes hour by hour as new arrestees enter and released inmates exit through the booking lobby.
Daily Population Count
The daily Inmate Population count records the number of persons held in the detention facility at the end of the 24-hour reporting period. You see this number on the Justice Services website shortly after midnight on the following day. The count covers all housing units, medical beds, and isolation cells inside the Justice Center.
Daily counts help you track short-term shifts caused by weekend arrest patterns, holiday court calendars, or large law-enforcement operations. When the count rises sharply, you can compare it with the daily admissions log to find the cause. When the count drops, the daily releases report shows how many people left custody and why.
Population Reporting Date
Every published Inmate Population figure carries a precise population reporting date that shows when staff recorded the count. The reporting date appears next to the headcount on the public portal so you know the freshness of the data. The timestamp follows a standard format, which makes it easy to match the count to a particular day, week, or month.
Justice Services ties each reporting date to a single morning snapshot so counts stay consistent across reports. You can use the reporting date to align population data with court calendars, arrest logs, and release notices. This makes year-over-year comparisons accurate.
Total Custody Population
The total custody population represents every person under the supervision of the St Louis County Justice Center, regardless of where they sleep that night. The number combines detainees held at the main Justice Center with persons housed at contract facilities or other county locations. Justice Services publishes this total so you see the full picture of county-level custody, not just the on-site count.
Population Data Source
Justice Services compiles the Inmate Population from the jail management system used by the St. Louis County Police Department. Each booking, release, and transfer updates the system in real time, and a nightly batch process locks the official count for the day. The same system feeds the public portal, so the numbers you see match the records officers use on duty.
Inmate Population by Facility
The Inmate Population by Facility view breaks the total count down by physical location. You see how many people sit in the main Justice Center and how many sit in any annex or contract site operated by the county. This view helps you understand capacity pressure at each building.
St Louis County MO Jail Population
The St Louis County MO Jail Population covers every person held inside the Justice Center at 100 South Central Avenue in Clayton. You can view the total headcount for this main facility along with housing unit breakdowns. The Justice Center is the primary intake site for arrests made anywhere in the county.
Detention Facility Counts
Detention facility counts show how many detainees sit in each housing area, from minimum-security dorms to maximum-security cells. You see how the population splits between general population, protective custody, and medical units. The breakdown helps you gauge staffing needs and programming space.
| Facility Section | Typical Population Range | Primary Use |
|---|---|---|
| General Population – Male | 400-450 | Housing for sentenced and pretrial males |
| General Population – Female | 100-130 | Housing for sentenced and pretrial females |
| Medical Unit | 30-50 | Inmates needing medical or mental health care |
| Administrative Segregation | 40-70 | Inmates separated for safety or discipline |
Facility Capacity
The St Louis County Justice Center operates with a rated facility capacity of 1,578 beds. The capacity figure reflects the number of beds the building was designed to hold under normal operating conditions. You can use this number to calculate the occupancy percentage for any given day.
Occupied Beds
Occupied beds reflect the number of people physically assigned to a bed at the reporting time. On most days, occupied beds fall between 780 and 820, which keeps the Justice Center near ninety percent of capacity. The count moves up or down based on daily admissions and releases, court outcomes, and transfer activity.
Available Capacity
Available capacity equals the rated facility capacity minus the occupied beds. You see a small buffer of unfilled beds on most days, which lets staff handle short-term surges after large arrest events. The buffer also covers isolation holds, medical placements, and pending transfers that require temporary separation.
Inmate Population by Custody Category
The Inmate Population by Custody Category view groups detainees based on their legal status. You see separate totals for people who have not yet been sentenced, those serving county sentences, and those held for other agencies. The custody category drives housing decisions, program eligibility, and release timing.
Pretrial Population
The pretrial population includes every person held in custody while waiting for their court case to resolve. Most people in this group have not been convicted and are presumed innocent. You see this category grow on weeks when arrest activity rises and shrink when bond conditions ease.
Sentenced Population
The sentenced population covers people serving a county sentence of one year or less at the Justice Center. These individuals have been convicted and are completing their court-ordered time. You can see their numbers shift when courts issue new sentences or when inmates finish their terms and exit custody.
Federal or State Holds
Federal or state holds apply to detainees wanted by a federal agency or the Missouri Department of Corrections. St Louis County MO holds these individuals on a contract basis until the outside agency picks them up. You see this category on the custody report so the count stays separate from local detainees.
Transfer Population
The transfer population covers detainees waiting to move to another facility, such as a state prison or a different county jail. Transfer waits can last several days depending on transport schedules and bed availability at the receiving site. You can track this group to see how movement affects the daily headcount.
Other Custody Categories
Justice Services also reports on smaller custody categories, such as persons held for contempt, material witnesses, and protective orders. These groups make up a small share of the total Inmate Population, but you see them broken out for full transparency. Each category carries its own release path and reporting rules.
| Custody Category | Approximate Share | Release Path |
|---|---|---|
| Pretrial | ~70% | Bond, court order, or case dismissal |
| County Sentenced | ~20% | Sentence completion or parole |
| State or Federal Hold | ~5% | Picked up by outside agency |
| Transfer or Other | ~5% | Transport or special court order |
Inmate Population Demographics
The Inmate Population demographics view adds a human layer to the raw headcount. You see the age, gender, and other published characteristics of people in custody on a given day. This data supports research, policy planning, and program design at the county level.
Age Groups
Justice Services publishes Inmate Population counts in standard age bands, such as 18-24, 25-34, 35-44, 45-54, and 55 and older. You can use these bands to study how age distribution shifts over time. Most of the population sits in the 25-44 range, with smaller shares at the youngest and oldest ends.
Gender Categories
The gender breakdown shows how many people in custody identify as male, female, or non-binary. You see this split on the public portal and in the annual demographic report. Male detainees make up the majority of the daily population, while female and non-binary detainees make up a smaller share.
Other Published Demographics
Justice Services may also publish additional demographic markers when the data supports it. You can look for race and ethnicity breakdowns in annual reports, along with veteran status where self-reported at booking. These markers help researchers and community partners study disparities and outcomes.
Reporting Periods for Demographic Data
Demographic data follows its own release cycle. Daily counts show only the total headcount, while monthly and annual reports add the demographic breakdown. Residents can also access official current inmates to verify current details. You see a richer demographic picture at year-end, when Justice Services publishes a full statistical report covering all published categories.
Historical Inmate Population
The historical Inmate Population data lets you look back at how the headcount changed over time. You can compare today’s figure with counts from prior days, months, and years. This data is helpful when you study trends, write reports, or support policy decisions.
Daily Historical Counts
Daily historical counts archive each day’s headcount with a timestamp. You can scroll back through past counts to see how the population responded to specific events. The archive starts from the date the public portal launched and grows each morning.
Monthly Population Data
Monthly population data rolls the daily counts into one summary per month. You see the average daily population, the highest daily count, and the lowest daily count for each month. Monthly reports also note special events that drove swings, such as holiday weekends or large court dockets.
Annual Population Data
Annual population data gives you the widest view of long-term change. Justice Services publishes a yearly statistical report that compares each year’s totals and demographic breakdown. You can use the annual report to measure growth, decline, or stability over multiple years.
Historical Facility Capacity
Historical facility capacity figures show how the rated bed count changed as the Justice Center expanded or contracted. You can match capacity changes to construction projects, policy shifts, and population pressure. The history helps you understand why today’s occupancy rate looks the way it does.
Long-Term Population Trends
Long-term population trends let you see the direction of the Inmate Population over years. You can plot the data to find periods of growth, periods of decline, and stable plateaus. Trends reflect changes in arrest policy, court practice, and community conditions across St Louis County MO.
Inmate Population Reports
Justice Services publishes Inmate Population reports on a set schedule so you always know when new data drops. Reports cover daily, monthly, and annual timeframes, and each report links back to the underlying daily counts. You can pick the report that matches the question you are trying to answer.
Daily Population Reports
Daily population reports show the headcount for a single day, broken down by custody category and housing area. You see the report on the public portal the morning after the reporting date. Daily reports are the freshest source of truth for the current Inmate Population.
Monthly Reports
Monthly reports combine the daily counts into one summary for each calendar month. You see the average daily population, peak day, low day, and a breakdown by custody status. Monthly reports give you a steady view of how the population moved over a four-week window.
Annual Reports
Annual reports cover a full calendar year and add the deepest level of detail. You see yearly averages, demographic breakdowns, admissions and releases, and capacity use. Annual reports are the right choice when you study long-term change or write policy briefs.
Population Statistics
Population statistics compile key numbers from each report into one easy-to-scan file. You see totals, averages, and percentages in a table. The statistics help you compare periods quickly without reading the full report.
Archived Reports
Archived reports store older daily, monthly, and annual publications in one section of the portal. You can pull up a past report by date, year, or topic. The archive goes back several years and grows with each new release.
Inmate Population Changes
The Inmate Population changes section shows the daily movement that drives the headcount up or down. You can see how many people entered custody, how many left, and how many moved between facilities. Tracking these flows helps you understand the forces behind the daily number.
New Admissions
New admissions count every person booked into the Justice Center during the reporting day. You see this number climb on weekends and after large law-enforcement operations. Admissions reflect local arrest activity, not just serious crime, since the booking lobby processes every arrest made in the county.
Releases
Releases count every person who left custody during the reporting day through bond, sentence completion, court order, or other path. You can match the release count to the bond docket and sentencing calendar. Releases often spike after morning court sessions.
Transfers
Transfers cover people moving in or out of the Justice Center to another facility. You see transfers going out to state prisons and transfers coming in from contract sites. Transfers affect the daily count but do not change the broader county custody picture.
Population Increases
Population increases happen when admissions and incoming transfers outpace releases and outgoing transfers. You see this pattern on days with heavy arrest activity or low court output. The increase shows up the next morning on the daily count.
Population Decreases
Population decreases happen when releases and outgoing transfers outpace admissions and incoming transfers. You see this pattern after bond hearings, mass release days, or large state pickups. Decreases free up bed space and ease occupancy pressure.
Inmate Population Data Access
The Inmate Population Data Access section shows where you can find the numbers and what you can do with them. Justice Services publishes most data online so you can pull it without filing a formal request. Some records stay restricted to protect privacy and active investigations.
Online Population Information
Online population information sits on the St. Louis County Police Department website under the Jail & Inmate Information tab. You see today’s headcount, custody breakdown, and capacity use on the public portal. The page updates each morning with the latest count.

Downloadable reports let you save Inmate Population files to your own computer. You can open monthly and annual reports as PDF files, and the statistics file comes in a spreadsheet format. The downloads are free and carry no usage fee.
Historical Data Access
Historical data access covers counts that go back to the launch of the public portal. You can pull archived daily reports by date or pull monthly and annual summaries by year. The archive grows each morning as the new daily count is added.
Restricted Information
Restricted information stays out of public view to protect privacy, active cases, and safety. You cannot see juvenile detention figures, sealed court orders, or the identities of protected witnesses. Justice Services explains the restriction on the portal so you know what falls outside the public dataset.
- Today’s headcount
- Custody category breakdown
- Housing unit occupancy
- Admissions, releases, and transfer log
- Monthly and annual summaries
Inmate Population Data Accuracy
The Inmate Population Data Accuracy section explains how Justice Services keeps the numbers clean. You see the steps staff take to update counts, fix errors, and flag delays. Knowing these steps helps you judge how much weight to put on any given figure.
Population Count Updates
Population count updates happen continuously inside the jail management system. Each booking, release, and transfer writes a new record that adjusts the running total. The system locks the count at a set time each morning so the published figure stays stable.
Reporting Delays
Reporting delays can occur when the jail management system pauses for maintenance, when court calendars shift, or when a holiday changes the reporting cycle. You see a clear date stamp on every figure so you know when the count was taken. Residents can also access official warrant records to verify current details. Delays are noted on the portal so users do not mistake old data for new.
Differences Between Reports
Differences between reports can show up because each report covers a different time window. The daily report uses a single morning snapshot, the monthly report uses daily averages, and the annual report uses yearly totals. You should match the report to the question you want to answer.
Corrected Population Data
Corrected population data happens when staff find an error in a past count. Justice Services issues a correction note on the portal and updates the archived file. The corrected version carries the same date but a new “revised” flag so users know what changed.
Limitations of Published Counts
Limitations of published counts include the snapshot timing, the in-transit gap during transfers, and the privacy rules on juvenile data. You should treat each number as a point-in-time view rather than a live ticker. Justice Services lists these limits on the portal so you do not read more into the data than it shows.
Inmate Population Questions
The Common Inmate Population Questions section answers the most frequent user questions about the daily count. You see short explanations that cover why numbers move, why some figures look different, and where to find older records.
Why Does the Population Count Change?
The Inmate Population count changes because new arrestees enter the booking lobby and current detainees leave through bond, court order, or sentence completion. Every booking writes a new entry in the system, and every release writes an exit entry. The running total adjusts hour by hour.
Why Do Facility Counts Differ?
Facility counts differ because some detainees sleep at the main Justice Center and others sleep at contract sites or other county buildings. The total custody figure adds these locations together, while the jail-specific figure shows only the Justice Center count. Reading the chart title helps you pick the right number.
Why Is Recent Population Data Missing?
Recent population data can be missing when a reporting cycle has not closed yet, when the system is in maintenance, or when a holiday shifts the schedule. Justice Services posts a notice on the portal when a delay affects the daily count. The next morning’s update restores the full series.
How Often Is Population Data Updated?
Population data updates each morning with the count from the previous reporting day. The jail management system processes new bookings and releases around the clock, but the official snapshot locks in at the end of each cycle. You see the new number on the portal the next day.
Where Can Historical Population Data Be Found?
Historical population data sits in the archive section of the Justice Services portal. You can browse past daily reports by date, past monthly reports by month, and past annual reports by year. Each archived file is free to download.
Inmate Population and Related Records
The Inmate Population and Related Records section shows how the daily headcount connects to other public records. You see how population data lines up with booking rosters, court calendars, and release notices. Matching these records helps you build a clear picture of a case.
Inmate Population vs. Current Inmates
The Inmate Population figure counts every person housed at the Justice Center at the reporting time. The current inmates list shows the same group, broken out by name, booking number, and housing unit. You can use the headcount as a quick total and the inmate list for individual details.
Inmate Population vs. Current Bookings
Current bookings cover people who entered custody during the reporting day. The Inmate Population counts everyone in custody, not just the new entries. You can compare the two to find how many detainees were already inside when the new bookings arrived.
Inmate Population vs. Jail Roster
The jail roster lists every person currently in custody, with their basic identifiers. The Inmate Population count adds up that roster into one figure. You can move between the two with a single click on the portal.
Inmate Population vs. Booking Reports
Booking reports show who entered custody and when, along with charges and bond status. The Inmate Population count does not list names, but it does reflect every booking. You can use both to follow a person’s path from arrest to release.
Inmate Population vs. Jail Records
Jail records cover the full history of a person’s stay, including moves, programs, and medical notes. The Inmate Population count is just the daily total. You pair the count with jail records when you need a full story.
| Record Type | Scope | Best Use |
|---|---|---|
| Inmate Population | Daily total headcount | Quick snapshot of how many people are in custody |
| Current Inmates | Named list with identifiers | Look up an individual detainee |
| Booking Reports | Daily new entries | Track new admissions and charges |
| Jail Roster | Full active roster | Browse all detainees in custody |
| Jail Records | Full history per person | Review stays, moves, and program notes |
