How to Look Up Clay County Jail Population Data
The two official sources for Clay County jail population data are the Sheriff's live detention listings and the Sheriff's annual report. The Clay County detention listings page shows a current snapshot of who is in custody. The page refreshes every four hours. It is a roster, not a dashboard, so it does not publish a running headcount across the page. Counting names on the roster at one moment gives a point-in-time number, not an average.
The Sheriff's annual report is the better source for population trends. The Sheriff's Office release dated March 27, 2026 covers the 2025 annual report. The release publishes the average daily population, year-over-year change, and longer trend context. For the most recent year, the official annual-report figure is the one to use. The Bureau of Justice Statistics publishes the most reliable state and national benchmarks for jail population, broken down by jail size and county.
Clay County Jail Capacity Overview
The Clay County Detention Center at 14 S. Water Street in Liberty is the single jail facility in the county. The Sheriff's Office runs the building. Booking, classification, housing, video visitation, and commissary all sit inside the same address. The Sheriff publishes the detention listings out of this facility. The table below captures the official numbers found on the Sheriff's site. One key figure, the rated bed capacity, is not posted on the official sheriff pages reviewed for this build.
| Facility | Address | Rated Capacity | Update Cadence |
|---|---|---|---|
| Clay County Detention Center | 14 S. Water Street, Liberty, MO 64068 | Not published on official sheriff pages reviewed | Roster updates every four hours |
Note: Third-party data sites publish capacity figures for the Clay County jail, but those numbers are not used here because they are not on a primary government source. The official rated bed count should be confirmed with the Sheriff's Office at 816-407-3800 before relying on any number.
Average Daily Population
The Sheriff's 2025 annual report release is the strongest official population figure for the Clay County jail. The average daily population grew from 289 in 2024 to 345 in 2025. That is a 19 percent year-over-year increase. The same release says 2025 marks a 38 percent increase from 2023, which puts the 2023 average daily population near 250 if the percentage is rounded. The build should quote the official percentages rather than the implied 2023 count unless the underlying annual report table is checked again.
Operational pressure rose with the population. The 2025 annual report release notes that inmate-versus-inmate assaults dropped 9 percent and inmate-versus-staff assaults dropped 73 percent despite a higher headcount. Bailiff service volume also climbed: deputies served as bailiffs at 71,156 court cases in 2025, up 11 percent from the prior year. The numbers point to a busier jail and busier courthouse for the same Sheriff's staff.
Demographic Breakdown
The Sheriff's detention listings page records race and sex for every booked inmate. A live roster check can give a point-in-time demographic snapshot. The aggregate demographic breakdown for the full year, however, is not published on the official sheriff pages reviewed for this build. The fields are collected at intake but rolled-up percentages are not posted online.
| Group | Source Note |
|---|---|
| Sex | Recorded at intake; per-inmate value visible on the public detention detail card. |
| Race | Recorded at intake; per-inmate value visible on the public detention detail card. |
| Age | Not on the public detention detail card; tracked internally for bookings. |
| Aggregate percentages | Not published on official sheriff pages reviewed; ask the Sheriff's Office for annual-report breakdowns. |
Researchers who need a verified aggregate breakdown can request it from the Sheriff's records custodian under RSMo 610.023. The custodian has three business days to act on the request.
Pretrial vs Sentenced Population
National jail studies consistently show that most county-jail populations skew pretrial. Bureau of Justice Statistics jail reports put the national pretrial share around two-thirds of the full local jail population. The Clay County Sheriff's site does not publish a county-specific pretrial-versus-sentenced split for the Clay County jail, so the local share is not stated here. A confirmed figure has to come from the Sheriff's annual report or a Sunshine Law request.
The case-flow pattern matters for population planning. Pretrial inmates are people booked into the Clay County jail who have not yet been convicted. They often sit while waiting on bond, plea negotiation, or trial setting at the Circuit Court divisions covered on the Clay County Circuit Court page. Sentenced inmates are people serving a county sentence, usually a year or less. Anyone serving a longer state sentence moves to a Missouri Department of Corrections facility.
Misdemeanor vs Felony Population
Charge mix shapes jail population. Felony cases tend to involve higher bond amounts and longer pretrial stays. Misdemeanor cases more often release on summons, bond, or a quick plea. The Clay County Sheriff's site does not publish a charge-class breakdown of the jail population, but the Circuit Court's Criminal Department processes both classes. Felony filings flow through Circuit Court Division 2, while misdemeanors and many traffic cases pass through Associate Circuit divisions.
People reviewing population data should remember that one booked person may have several charges across both classes. A single bond hearing may set conditions for a felony and a misdemeanor at the same time. Population counts the body, not the charges, so a single high-profile booking with multiple charges still adds one to the daily count.
Mental Health and Medical Population
Jails serve a population with higher-than-average mental health and medical needs. National BJS data shows a sizable share of jail bookings have prior mental health treatment, substance abuse history, or chronic medical conditions. Local data for the Clay County jail's mental health and medical share is not posted on the Sheriff's public pages. Treatment courts in Division 1 of the Seventh Judicial Circuit, including the Mental Health Court and Adult Substance Abuse Court, route qualifying defendants out of standard sentencing and into structured treatment dockets.
People with active civil commitments under Chapter 632 are handled in the Probate Department of the Circuit Court, not the criminal divisions. Commitment files are confidential under RSMo 630.140. Probate court records and process are covered on the Clay County probate records page.
National and State Context
National benchmarks help place the Clay County jail in context. The Bureau of Justice Statistics is the official source. Its Census of Jails and Annual Survey of Jails publish state and county-level rates per 100,000 residents. The Vera Institute also publishes incarceration trends for many counties, drawing on the same BJS underlying data. The table below sets up the comparison frame. Cells marked "see source" point to figures that should be pulled fresh from the BJS report rather than restated here.
| Level | Jail Population Source | Rate per 100k |
|---|---|---|
| Clay County | Sheriff's annual report; 2025 ADP 345 | See source; rate per 100k not published on official sheriff pages reviewed |
| Missouri (state) | BJS Annual Survey of Jails | See source |
| United States (national) | BJS Census of Jails | See source |
Note: Published BJS national rates have hovered around the low-to-mid 200s per 100,000 residents in recent reporting cycles, but the build does not cite a specific number because the official BJS table was not extracted into the research file.
Population Trends Over Time
The Clay County jail population trend over recent years moves sharply upward. The Sheriff's 2025 annual report release puts the average daily population at 345 in 2025, 289 in 2024, and a 38 percent rise from 2023 to 2025. That is a fast climb by national standards, which mostly moved in the opposite direction during the same window. The local jail therefore runs against the broader downward trend many county jails saw in the early 2020s.
Several drivers can explain the rise: charging changes, bond-setting patterns, court backlog from earlier years, or local arrest activity. The Sheriff's annual report release does not single out any one cause. Court bailiff cases rose 11 percent in the same period to 71,156, which points to higher court volume rather than only longer stays. Researchers who want to model the trend should pair Sheriff data with Circuit Court filing counts from the Seventh Judicial Circuit and Case.net pull dates.
Searching for Clay County Inmate Records by Name
The page covers aggregate jail population data, not individual inmate lookups. For a name-based search of the live jail roster, see Clay County inmate records. That page walks through the detention listings, profile fields, bond posting, and visitation rules. For people who have been released, see released inmates.
Where the Data Comes From
Three official sources feed any honest Clay County jail population report. The first is the Sheriff's live detention listings, which refresh every four hours. The second is the Sheriff's annual report, with the 2025 release dated March 27, 2026. The third is the Bureau of Justice Statistics jail program, which provides state and national context. Where the Sheriff's Office does not publish a number, the right move is a Sunshine Law request under RSMo 610.023 to the Sheriff's records custodian, Captain Chris Johnson, rather than a guess from a third-party data site.
Data integrity matters. Case.net is the public case management portal for the Missouri Judiciary and is described on the official Missouri Courts Case.net help page. It tracks the case, not the person in jail. Case.net counts and Sheriff roster counts do not match because not every charged person sits in custody, and not every person in custody has a Clay County case. Researchers should use the Sheriff's count for jail population and Case.net for case-level filings.
Note: Court Operating Rule 2 bans automated scraping of Case.net, so jail and court datasets must be combined with care and not pulled by bot.
