How to Look Up Cameron County Jail Population Data
Official jail population data does not live on the Sheriff's inmate roster. It lives in state reports. The Texas Commission on Jail Standards, known as TCJS, is the state body that oversees county jails. TCJS publishes monthly population reports with a line for each county. That line is where the real Cameron County numbers sit: total population, rated capacity, percent of capacity, and, when present, a pretrial and sentenced split. The county's own Jail Division page lists facilities but does not publish average daily population or demographic breakdowns.
Reading the data means going to the right report and the right column. A TCJS monthly report shows a snapshot for the reporting date, so it is a point-in-time count, not a daily average. For national and state context, the Bureau of Justice Statistics, or BJS, publishes annual jail data. To find the official figures, use the Texas Commission on Jail Standards reports rather than a screenshot of the live roster.
Reading tip: A TCJS monthly figure is a snapshot for one reporting date, while average daily population smooths the count across a month, so the two numbers differ.
Cameron County Jail Capacity Overview
The Cameron County jail system includes facilities in Brownsville and Olmito. The county's Jail Division page lists each facility with an address and phone, but it does not publish a rated capacity per facility. TCJS-related material reports a system capacity of roughly 1,746 for the Cameron County Jail. That figure should be treated as a reported system total and verified against the current TCJS jail profile before it is used for any calculation.
The table reflects what is and is not published. Per-facility capacities were not located in the county sources reviewed, so those cells are marked rather than filled with guesses.
| Facility | Location | Rated Capacity |
|---|---|---|
| Cameron County Jail | 954 E. Harrison St., Brownsville | Per-facility figure not located |
| Carrizales-Rucker Detention Center | 7300 Old Alice Road, Olmito | Per-facility figure not located |
| Ruben Torres Detention Center & Detention Center II | 1145 E. Harrison St., Brownsville | Per-facility figure not located |
| Cameron County jail system total | Multiple sites | Approx. 1,746 reported (verify with TCJS) |
Note: The roughly 1,746 figure is a reported system total from TCJS-related material and should be checked against the current TCJS jail profile.
Average Daily Population
Average daily population, or ADP, smooths the count across a month or a year. It is the better measure of how full a jail runs than a single-day snapshot. An official ADP figure and a multi-year trend for Cameron County were not located in the county pages reviewed. So the honest answer is that the county does not publish ADP on its own site.
The path to an ADP figure runs through TCJS monthly population reports. Pulling the Cameron County line across several months gives a usable average. BJS data provides the national and state backdrop. Neither the Sheriff's roster nor a one-time row count should be used to estimate ADP, because the roster is incomplete and changes every two hours.
Demographic Breakdown
A demographic breakdown of the Cameron County jail population was not located in official county sources. The roster itself does not display age, date of birth, race, or sex, so it cannot be used to build a demographic profile. No age, race, or sex percentages are published here because inventing them would be wrong. Where a breakdown is needed, TCJS and BJS publications are the proper sources.
The table below states the data status plainly rather than filling cells with estimates.
| Demographic Measure | Data Status |
|---|---|
| Sex breakdown | Not published by the county; check TCJS or BJS. |
| Race or ethnicity | Not located in official county sources. |
| Age distribution | Not shown on the roster or county jail pages. |
Pretrial vs. Sentenced Population
Many people in any county jail are held before trial, not after a conviction. A pretrial detainee is awaiting a court outcome and is presumed innocent. A sentenced inmate is serving time after a conviction. TCJS monthly reports often break out the pretrial and sentenced counts in the county line, which is the right place to read the split for Cameron County.
A specific pretrial and sentenced percentage for Cameron County was not located in the county sources reviewed, so the table flags the data status instead of stating a number.
| Status | Where to Find It |
|---|---|
| Pretrial | TCJS monthly population report, Cameron County line. |
| Sentenced | TCJS monthly population report, Cameron County line. |
Misdemeanor vs. Felony Population
Jail populations also split by charge level. Misdemeanors are lower-level offenses, often handled by the county courts at law. Felonies are more serious and run through the district courts. The county does not publish a misdemeanor-versus-felony breakdown of its jail population on the pages reviewed. For charge-level context, court filing data and TCJS reports are better sources than the live roster, which lists charge text for reference only.
Mental Health and Medical Population
Jails carry a real medical and mental health load, but Cameron County does not publish a count of inmates receiving such care. The Jail Division does state a clear privacy rule: no medical information on any inmate is given to family, for security reasons. Prescribed medicine may be brought in but must be approved by the medical department, and family calls are not transferred to medical staff. So while the share of the population in care is not published, the privacy framework around it is.
Cameron County does run a mental health divert court, which steers some defendants toward treatment instead of jail. That program is a court diversion effort, not a jail population statistic.
National and State Context
National context helps make sense of any single jail's numbers. The Bureau of Justice Statistics publishes annual jail population data and pretrial trends for the whole country. The Vera Institute, a nonprofit, publishes county-level incarceration dashboards, though it is not an official government source. Together they frame how a county like Cameron compares, even when the county does not post its own rate.
A verified jail population per 100,000 residents for Cameron County, Texas, and the nation was not assembled from official sources during research, so the table points to where each rate can be obtained rather than stating unverified figures.
| Level | Where to Get the Rate |
|---|---|
| Cameron County | TCJS population report divided by Census QuickFacts population (431,874 in 2024). |
| Texas | Bureau of Justice Statistics state jail data. |
| National | Bureau of Justice Statistics annual jail inmates report. |
The county's resident base gives the denominator: the 2020 census counted 421,017 people, the 2024 estimate is 431,874, land area is 891.71 square miles, and density is 472.1 per square mile.
Population Trends and Oversight
A multi-year Cameron County jail population trend was not located in the county pages reviewed. The way to build one is to pull the Cameron County line from successive TCJS monthly reports. That approach uses official figures and avoids the error of reading the live roster as a trend line.
Oversight is part of the picture too. On May 23, 2025, TCJS issued a notice of non-compliance for the Cameron County Jail after a May 21, 2025 inspection. The notice referenced minimum standards tied to jailer observation and documentation. This is recent official oversight context and is stated here neutrally, without conclusions about current status.
Oversight note: A TCJS notice of non-compliance reflects inspection findings on a given date and does not, by itself, describe the jail's current population or staffing level.
Searching for Cameron County Inmate Records by Name
This page covers aggregate jail population data, not individual lookups. To search for a specific person on the live jail roster by name, booking number, or charge, use the Cameron County inmate records page, which explains the roster and its limits. The population figures here and a single name search answer two different questions.
Where the Data Comes From
The strongest sources for Cameron County jail population are official and statistical, not the live roster. TCJS monthly population reports give total population, capacity, percent of capacity, and pretrial or sentenced counts. TCJS inspection reports and notices show operational status. The county budget and Commissioners Court minutes carry staffing and contract detail. BJS supplies the national and state backdrop, and Census QuickFacts supplies the resident population denominator.
It is worth repeating why the roster is the wrong tool here. The live inmate list omits federal detainees and prisoners, includes only certain current and last-seven-day categories, and updates every two hours. A row count at one moment is not an average daily population. For official figures, start with TCJS and the Bureau of Justice Statistics.
Reading a TCJS report is straightforward once you know the layout. Each monthly report lists a line for Cameron County with the total population on the report date, the rated capacity, and the percent of capacity in use. Compare the latest population to the reported system capacity of about 1,746 to judge whether the jail is running below, near, or above its rated limit. Some reports also separate pretrial detainees from sentenced inmates and flag contract or federal holds where they apply. For spending and staffing, the Cameron County adopted budget and the Commissioners Court agendas cover jail medical contracts, food service, commissary, and construction items that population numbers alone do not show.
