Merced County Jail Population Data

How to Look Up Merced County Jail Population Data

Merced County jail population data sits in two public Sheriff's tools and two federal data sets. The first is the Sheriff's online Inmate Inquiry. The page shows a paged list of people held by the Merced County Sheriff's Office at the moment the page loads. On May 19, 2026, the list showed 764 records, with paging marked "Showing 1 to 100 of 764." That number is the live public-search count for Merced County. It is not an audited average daily population, and it can change by the hour as people are booked or released.

The second source is the Sheriff's In-Custody Deaths page, which lists deaths in custody under Penal Code section 10008 and Assembly Bill 2761. The third source is the federal Bureau of Justice Statistics, which runs national jail counts and prints a state-level rate per 100,000 residents. The fourth source is the Vera Incarceration Trends tool, which holds county-level jail data over time. The image below is the BJS landing page that hosts the national jail data series cited later on this page.

BJS data is the standard yardstick when a county jail count is set next to state and national figures. The Sheriff's Inmate Inquiry, by contrast, is best read as a point-in-time count of the Merced County jail system on the day of the search.

Merced County Jail Capacity Overview

The Merced County jail system runs out of two main sites. The Main Jail sits at 700 W. 22nd Street in Merced. The John Latorraca Correctional Center, often shown as JLCC, sits at 2584 W. Sandy Mush Road in El Nido. A current rated bed capacity for each site was not located on the visible Sheriff facility pages during research. A county correctional facility exhibit found in official county documents states that the Merced County jail system has run over rated capacity since 1992, and that the system's average daily population has averaged 962 since 2009, with that figure exceeding rated bed capacity by 21%. That exhibit may not be current, so it should be read as historical context, not a present-day capacity table.

The cells marked "not located in current official visible source" are honest gaps. A confirmed current capacity for the Main Jail and JLCC would need to come from the latest Board of State and Community Corrections jail profile, the latest Merced County budget, or a direct facility tour record. Until then, the 21% overcrowding figure is the only published systemwide context.

Average Daily Population in Merced County

Average daily population, or ADP, is the mean count of people held each day across a year. The county correctional facility exhibit places Merced County jail system ADP at 962 since 2009. That same exhibit states the figure exceeded rated bed capacity by 21%, and that chronic overcrowding has run since 1992. ADP is the standard jail planning number, since it smooths out the daily booking and release churn that moves the live count up and down. For Merced County, the ADP figure is historical context. It is not a fresh 2026 reading.

The live Inmate Inquiry count of 764 on May 19, 2026 sits below the 962 historical ADP. That gap may mean the live count is simply a low day in the cycle, or it may mean ADP has dropped since the exhibit was written. Without a current Board of State and Community Corrections jail profile reading or a fresh county audit, the build cannot state which one is true. For now, hold both numbers side by side. The 962 figure is the historical ADP yardstick. The 764 figure is the public-search count on one day in May 2026.

Housing Facility Categories in Merced County

The Sheriff's Inmate Inquiry asks users to pick a housing facility from a dropdown. The dropdown values map to where a person is being held or what their custody status is at search time. Some values are physical sites. Some are status flags. The list below mirrors the live dropdown that the Merced County jail system publishes.

The mix of physical and status values means a raw count of all dropdown rows does not equal the count of people in a Merced County jail bed. A reader who wants only bed counts has to filter to Main Jail and JLCC, and treat the other rows as outside the brick-and-mortar jail count. The Sheriff's locations page shows the two main sites on a map.

The locations page is the cleanest single view of where the Merced County jail system holds people, even though it does not list a bed count for each site.

Pretrial vs Sentenced Population in Merced County

The Merced County In-Custody Deaths page is the clearest published signal on the pretrial split inside the jail system. Of the six deaths listed across 2023, 2024, and 2025, five carry a custodial status of pretrial. Only one carries a status of partially sentenced. That ratio fits the broader national pattern, where most county jail residents are held before trial rather than after sentencing. Pretrial detention can stem from a bail hold, a no-bail flag, a probation hold, or a parole hold. Sentenced county jail residents are typically serving misdemeanor terms or local felony terms under California's Public Safety Realignment.

A precise pretrial-versus-sentenced split for the live Inmate Inquiry count of 764 was not published on the page during research. The Sheriff does not break out the live list by custodial status. For a hard split, the source of record is the Board of State and Community Corrections jail profile or a Merced County budget jail line. Until that data is captured, the in-custody deaths sample is the only published cut, and it leans heavily pretrial.

In-Custody Deaths and Reporting Under PC Section 10008 and AB 2761

Penal Code section 10008 and Assembly Bill 2761 require county sheriffs to log and report deaths in custody. The Merced County Sheriff publishes that log on the In-Custody Deaths page. Each entry holds a reportable number, date, county, facility, location inside the facility, race, gender, age, custodial status, manner, and means. The table below holds the public entries for 2023 through 2025, drawn from the Sheriff's own page.

The image below is the Sheriff's In-Custody Deaths page, which is the source of record for these entries.

The page is updated when a new in-custody death takes place. The table is one of the few public reads on risk inside the Merced County jail system.

National and State Context

BJS is the federal lead on county jail data. Its annual jail report holds total counts, rates per 100,000 residents, and pretrial-versus-sentenced splits at the national and state level. The Vera Incarceration Trends tool drills down to single counties, including Merced County, and tracks change over time. Both sources are official or widely accepted research sources, so they sit cleanly next to the Sheriff's local figures.

The county-specific cell is the live Sheriff count plus the historical exhibit. The California and national cells need a fresh BJS pull to lock in the per-100,000 rate. That step keeps the comparison honest, since BJS reports use a rolling base year that shifts each cycle. Vera fills in the longer Merced County time series.

Historical Overcrowding in the Merced County Jail System

The county correctional facility exhibit is blunt. It says the Merced County jail system has run over rated bed capacity since 1992. It says the system's average daily population has averaged 962 since 2009. It puts the gap between ADP and rated capacity at 21%. That is the kind of structural overcrowding that drives county requests for jail construction grants, alternative sentencing programs, and pretrial release efforts. It also helps explain why the Inmate Inquiry housing dropdown holds values like OUT-OF-COUNTY and SUPERVISED RELEASE, since both are common pressure-relief tools when a county jail runs hot.

Overcrowding is not just a bed math problem. It feeds into staff load, medical care load, and risk of in-custody harm. The six in-custody deaths on the Sheriff's page over 2023 through 2025 sit inside that context. None of this is meant as a one-to-one cause and effect. It is meant as honest framing for the live Merced County jail count: the system has run over rated capacity for more than three decades, and the May 19, 2026 public-search count of 764 should be read against that long backdrop.

Where the Merced County Population Data Comes From

The data sources used on this page are listed below, with the official URL for each one. Every figure on this page should be traceable back to one of these sources.

• Sheriff Inmate Inquiry: live public-search count of 764 on May 19, 2026, plus the housing facility dropdown.
• Sheriff In-Custody Deaths: deaths under Penal Code section 10008 and AB 2761, 2023 through 2025.
• Board of State and Community Corrections jail profile: official source for current rated capacity at Main Jail and JLCC when the latest profile is reviewed.
• Bureau of Justice Statistics: national and state jail counts, rates per 100,000 residents, and pretrial split.
• Vera Incarceration Trends: county-level jail trend tool that holds Merced County over time.
• County correctional facility exhibit: historical context on ADP of 962 since 2009 and 21% over rated capacity since 1992.

For the live Sheriff numbers, refresh the Inmate Inquiry page before quoting any count. For BJS and Vera, pull the most recent year before quoting any rate.

Searching for Merced County Inmate Records by Name

Name-based lookups of single people held in the Merced County jail system are handled on the Merced County inmate records page, since this page covers aggregate jail population data only. The inmate records page walks through the Sheriff's Inmate Inquiry name search, booking number search, and the fields that come back on a single inmate profile.

Data Caveats

Two honest caveats apply to every figure on this page. The first is that the public-search count on the Sheriff's Inmate Inquiry is a point-in-time read, not an audited average daily population. A count taken at 9 a.m. on a Monday will not match a count taken at 9 p.m. on a Friday. The 764 figure on May 19, 2026 is one moment in that cycle. It should not be quoted as the Merced County jail's annual count.

The second is the capacity gap. The visible Sheriff facility pages reviewed during research did not publish a current rated bed capacity for the Main Jail or JLCC. The 962 ADP and 21% over-capacity figures come from an older county exhibit. Both are useful as historical context, but neither one is a fresh 2026 number. For confirmed current capacity, the source of record is the Board of State and Community Corrections jail profile or the latest Merced County budget.
