The Mason County Inmate Population
The Mason County inmate population is reported through Texas jail standards data and the county jail records held by the Mason County Sheriff's Office. Official research found one local detention facility inside the county: Mason County Jail, the jail function of the sheriff's office. The county jail population means people held before trial, people held for short local sentences, and people waiting on release, court, transfer, or housing elsewhere. It is not the same as the Texas state prison population. Once a Mason County defendant is sentenced to the Texas Department of Criminal Justice, that person is searched through the state prison locator instead of the local roster.
The count can move for simple reasons. A new arrest adds a person. A bond release, dismissal, sentence, transfer, or hold from another agency can remove one person from the visible local roster or move the case into another custody system. Because Mason County Jail has a very small bed count, one person changes the Mason County inmate population more than it would in a large urban jail. That is why the official roster, sheriff phone line, VINELink, public information request route, and state or federal locators all matter.
Mason County Inmate Population Statistics
The strongest official data point is the Texas Commission on Jail Standards county jail population reporting series. In the TCJS current population reports, the June 1, 2026 Mason County row listed a rated capacity of 5 beds, a total local plus contract plus federal jail population of 1, and 1 Mason inmate housed elsewhere in Texas. The related incarceration-rate workbook listed countywide population of 3,987, average daily population of 3, and an incarceration rate of 0.75. Annual bookings and average length of stay were not located in official Mason County sources.
| Measure | Figure | Source / Date |
|---|---|---|
| Rated capacity | 5 beds | TCJS County Jail Population workbook, June 1, 2026 |
| Total local plus contract plus federal jail population | 1 | TCJS County Jail Population workbook, June 1, 2026 |
| Percent of capacity | 20% | TCJS County Jail Population workbook, June 1, 2026 |
| Housed elsewhere in state | 1 | TCJS County Jail Population workbook, June 1, 2026 |
| Average daily population | 3 | TCJS Incarceration Rate workbook, June 1, 2026 |
| Countywide population used for rate | 3,987 | TCJS Incarceration Rate workbook, June 1, 2026 |
| Annual bookings | Not located | No official Mason County booking total found |
The TCJS population reports page is the state source used to verify these figures.
The TCJS page matters because it reports capacity and population data separately from the sheriff's live roster.
Mason County Inmate Population Trends
Mason County's trend table shows a small jail count rather than a sustained overcrowding pattern. From January 2024 through June 2026, the average daily population reported in the TCJS incarceration-rate workbook ranged from 1 to 4. The local count is therefore best read as a small-county trend, not a large statistical curve. A change from 1 to 4 people is still a major operational shift when the capacity is only 5 beds.
| Reporting Date | ADP | Incarceration Rate | Countywide Population |
|---|---|---|---|
| January 1, 2024 | 4 | 1.02 | 3,931 |
| June 1, 2024 | 3 | 0.76 | 3,931 |
| September 1, 2024 | 2 | 0.51 | 3,931 |
| December 1, 2024 | 1 | 0.25 | 3,931 |
| April 1, 2025 | 2 | 0.51 | 3,931 |
| September 1, 2025 | 2 | 0.50 | 3,987 |
| December 1, 2025 | 3 | 0.75 | 3,987 |
| April 1, 2026 | 4 | 1.00 | 3,987 |
| May 1, 2026 | 3 | 0.75 | 3,987 |
| June 1, 2026 | 3 | 0.75 | 3,987 |
No official Mason County source reviewed showed jail overcrowding litigation, a consent decree, a new jail campaign, or a closure announcement. The county sheriff page was updated in 2026 with a full-time jailer/dispatcher employment notice, which is a local operating detail rather than a population-policy change.
Mason County Jail Population Makeup
The June 1, 2026 TCJS county jail population row gives limited but useful detail about the Mason County jail population. The local jail count included 1 local male pretrial state jail felon. The same reporting series showed 1 Mason inmate housed elsewhere in state and identified that elsewhere person as a male convicted felon or parole violator sentenced to a TDCJ division. It also listed 0 federal inmates, 0 contract inmates, and 0 out-of-state housed inmates. Those are population categories, not a person-level roster.
- Local pretrial custody - the reported local count was one male pretrial state jail felon.
- Sentenced or housed elsewhere - one Mason inmate was reported housed elsewhere in Texas.
- Federal custody - the Mason row showed no federal inmates in the latest count reviewed.
- ICE detainers - latest TCJS immigration-detainer rows inspected showed no current ICE-detainer inmates for Mason.
Note: TCJS population categories do not replace a current custody check with the sheriff, Kologik roster, or VINELink.
Mason County Jail Capacity
Mason County Jail's 5-bed capacity is the main local capacity fact. At that scale, public-facing jail information is sparse. The official county page did not publish pod names, a housing-unit roster, construction history, a public lobby schedule, commissary vendor, or a separate booking desk number. The public jail contact route is the Mason County Sheriff's Office and dispatch. Capacity also helps explain why the Kologik roster can be empty. On June 30, 2026, the Mason ORI returned an empty current roster array, even though state reports can show a small average daily population or a person housed elsewhere.
Overcrowding language should stay precise. The June 1, 2026 TCJS row showed 1 person counted locally against 5 beds, or 20% capacity use. The trend data does not show a large sustained crowding problem in the official sources reviewed. If the live roster is empty, it does not prove there are no Mason County cases, no warrants, or no people held for Mason elsewhere. It only means no current public Kologik card was visible at the time of the search.
Mason County Jail Population Laws
Texas law controls how Mason County jail records, jail standards, capacity reports, bail decisions, and custody events are handled. The Texas Public Information Act is the request framework for public records held by a Texas governmental body. Jail records can still be limited by law-enforcement, privacy, juvenile, court-record, or criminal-history rules. The Mason County public information request form is the local route for records not visible in the online roster.
Key Statutes:
Texas Government Code Chapter 552 provides the public-information request framework for Texas government records, subject to exceptions.
Texas Local Government Code Chapter 351 covers county jail custody and sheriff responsibilities for safekeeping prisoners.
Texas Government Code Chapter 511 creates the Texas Commission on Jail Standards, the state body behind jail standards and population reporting.
Texas Code of Criminal Procedure Chapter 49 includes death-in-custody reporting rules.
Mason County State Prison Custody
The TDCJ unit directory did not identify a Texas state prison unit in Mason County. That means sentenced state prisoners from Mason County are not searched by facility name inside the county. They move into the Texas Department of Criminal Justice system and are searched through the official TDCJ sentenced-inmate locator. TDCJ records are different from county jail records. They focus on state identifiers, assigned unit, projected release, maximum sentence date, offense, sentence, and parole-related dates.
A Mason County jail booking can be the start of a case, while a TDCJ record reflects a state sentence after conviction and transfer. VINELink may help with custody notification, but it should not be treated as a replacement for the official state profile. For federal sentenced prisoners, use the Bureau of Prisons locator. For immigration detention, use ICE ODLS. Each system covers a different part of the broader inmate population connected to Mason County.
Search Mason County Inmates
Mason County uses the Kologik Public Jail Roster for the sheriff's public jail roster. The correct ORI-driven endpoint is TX1600000, and the Kologik agency-name endpoint returned Mason County Sheriffs Office during research. That ORI check matters because Kologik rosters are tied to agency codes. A wrong ORI can open the wrong county's roster.
The roster is free and does not require a login. On June 30, 2026, the current Mason roster API returned an empty array, so the roster had no public current inmate card to inspect. The search flow still matters because the same page is the first online channel when a booking is listed.
- Open the Kologik Mason County roster and confirm the header says Mason County Sheriffs Office.
- Select RECENT BOOKINGS for new entries, ALL for visible current listings, or a letter button to browse by last name.
- Use the Name Filter box to narrow visible roster cards by first, middle, or last name.
- Sort by shortest or longest days in jail when more than one card appears.
- If no card appears, call the sheriff's office or dispatch, check VINELink, and ask whether the person was released, transferred, or housed elsewhere.
The Mason County Kologik roster is the source for live local jail cards when a person is publicly listed.
Because the roster can be empty, phone, VINELink, and records-request channels are part of a complete Mason County inmate search.
Mason County Roster Search Fields
The Kologik interface uses filters instead of a separate submit button. The roster loads cards when public current data exists, then lets users narrow the results. For Mason County, history mode was not displayed because the history check returned no public history mode for the agency at inspection. Released records may also suppress charge detail with a notice that charges are not available for released people.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Name Filter | Text input | No | Filters loaded cards by last, first, or middle name. |
| Order By | Dropdown | No | Options include shortest in jail and longest in jail. |
| History | Dropdown, hidden for Mason at inspection | No | Current, past 5 days, and past 10 days exist in the app, but Mason history mode was not shown. |
| Letter buttons | Button filters | No | RECENT BOOKINGS, ALL, and A through Z change the server request. |
| Search button | None visible | Not applicable | The page filters as users type or select roster buttons. |
Mason County Released Inmate Records
Past and released Mason County inmate records are not handled the same way as current roster cards. Research found the public Kologik current roster empty on the inspection date, and the visible interface did not show a Mason history control. For an older booking, a booking photo not shown online, or a jail record that is no longer on the roster, the documented route is the Mason County public information request form linked through the county site. A good request should give the name, date, record type, and agency as clearly as possible.
Clerk records are different. The County Clerk and District Clerk maintain court pleadings, docket entries, settings, and case papers after charges are filed. The jail roster is a custody snapshot, while the court file is where filed charges and case status are tracked. If a person was sentenced to state prison, the TDCJ locator becomes the main search channel. If a person is in federal or immigration custody, use BOP or ICE ODLS instead of the Mason roster.
Mason County Inmate Record Fields
The Mason roster did not show a live current inmate card during inspection, but the Kologik app code shows the fields a public card can display when a card exists. Treat these as roster-system fields, not a promise that each Mason booking will show each field. The card itself is the public profile. It is not a separate click-through case file.
| Field | What It Shows |
|---|---|
| Name | Last, first, middle, and suffix in uppercase. |
| Arrested | Arrest or arrival date and time from the roster data. |
| Days Jailed | Calculated days in custody, with the current day added in display. |
| Demographics | Race, sex, date or year of birth, age, height, weight, eyes, and hair. |
| Arresting Agency | The agency tied to the arrest or booking. |
| Photo | A Kologik photo endpoint exists, and Mason was not configured to globally hide photos. |
| Charges | Charge code, literal, comments where shown, warrant number, and bond. |
| Release Date | May appear for released records, with charge detail suppressed in some cases. |
Mason County Jail vs TDCJ
Most search errors come from using the right name in the wrong system. Mason County Jail is for local pretrial detainees, short-term county jail inmates, and people awaiting release, court, transfer, or housing elsewhere. TDCJ is for sentenced state prisoners. Federal and immigration custody have separate locators. A person can also move through more than one system over time.
| County Jail | State Prison | Federal or ICE Custody | |
|---|---|---|---|
| Who is held | Pretrial and short-term local jail custody | Sentenced state prisoners | Federal prisoners or immigration detainees |
| Run by | Mason County Sheriff's Office | Texas Department of Criminal Justice | BOP, ICE, or U.S. Marshals channels |
| Where to look | Kologik Mason roster, sheriff phone, VINELink | TDCJ inmate search | BOP inmate locator or ICE ODLS |
| Record focus | Booking, arrest date, charges, bond, custody status | Sentence, unit, release dates, offense, parole fields | Register number, location, status, or A-Number search |
Mason County Outside Custody Search
Outside custody searches are a normal part of Mason County inmate lookup because the local jail is small and TCJS has reported Mason inmates housed elsewhere in state. Search the TDCJ inmate locator for a sentenced state prisoner. Use the Federal Bureau of Prisons inmate locator for federal sentenced inmates. Use ICE ODLS for immigration detainee searches by A-Number and country of birth or by biographic information.
VINELink is also available and is linked from the official Mason County sheriff page. It can help with custody status and release notification where a person is represented in the system. The Mason County Sheriff TX mobile app is available through the Apple App Store and Google Play and is described as a public outreach tool for reports, tips, and interactive communication. The app listings reviewed did not promise an inmate roster, warrant search, or booking-photo gallery, so the app should not replace the roster or official phone check.
The VINELink custody search is a useful notification channel for Mason County custody questions.
VINELink helps with alerts, while the originating sheriff, TDCJ, BOP, or ICE system remains the source to verify custody.
Mason County Detention Facilities
Official sources identified one detention facility inside Mason County. The Mason County Jail is operated by the Mason County Sheriff's Office at the sheriff's Mason location. No separate city jail, regional jail, work-release annex, TDCJ unit, BOP prison, ICE detention facility, or U.S. Marshals facility physically in Mason County was identified in the official sources reviewed.
- Mason County Jail - the local county jail and holding facility for pretrial detainees, short-term county jail inmates, and people awaiting release, court, transfer, or housing elsewhere.
Note: State-sentenced prisoners from Mason County are searched through TDCJ, not through a local facility page.
Mason County Custody Terms
The same person may appear in different records at different points in a case. These terms help separate the roster, court file, and state or federal custody systems without treating one as a final result.
- Booking
- Administrative entry into jail custody after arrest or surrender.
- Article 15.17 warning
- The Texas magistrate warning after arrest, where rights, accusations, and bond issues are addressed.
- Bond
- Security set to permit release while a criminal case is pending.
- Hold or detainer
- A request or order from another agency that can prevent release even when a local bond exists.
- TDCJ
- The Texas Department of Criminal Justice, which runs the state prison system.
Mason County Inmate Population FAQ
How big is the Mason County inmate population?
The June 1, 2026 TCJS county jail population row listed 1 local plus contract plus federal jail-population inmate for Mason County and 5 rated beds. The related incarceration-rate workbook listed average daily population of 3. Because the jail is small, each booking or release changes the percentage of capacity by a large amount.
Why might the Mason County roster be empty?
The Kologik current roster for Mason County returned no public current inmates during the June 30, 2026 inspection. That can happen in a very small jail. It can also happen when a person has been released, moved to another county, housed elsewhere, or transferred to state custody. Call the sheriff or dispatch when the live roster does not answer the custody question.
How do I search the Mason County inmate population?
Start with the Kologik Mason County roster for local jail custody. If no card appears, use the sheriff's office phone, dispatch, VINELink, in-person contact, or a public information request. For sentenced state prisoners, use TDCJ. For federal custody, use BOP. For immigration detention, use ICE ODLS.
Are Mason County jail records the same as court records?
No. Jail records show custody and booking details. Court records show the filed case, prosecutor action, docket settings, pleadings, charge status, and disposition. The County Clerk and District Clerk pages are the official local sources for Mason County criminal docket information after an arrest.
