How to Look Up Gloucester County Jail Population Data
There is no live dashboard for the Gloucester County jail population, because the county does not run a local jail. Instead, population data lives across several sources. County budgets and corrections contracts hold the spending and per-diem figures. Partner jails hold their own counts. Statewide and national surveys provide the broader frame. To build an accurate picture, you combine these rather than read one page.
The Bureau of Justice Statistics is the national authority on jail data. Its Census of Jails enumerates facilities and frames other surveys.
The BJS Census of Jails explains the scope and method behind national jail counts, which sets the context for any county-level reading. Pairing that national frame with state data and a county records request is the most reliable way to study Gloucester's numbers.
Gloucester County's No-Local-Housing Structure
Gloucester County's correctional position is unusual. The county Corrections page states that male, female, and juvenile offenders are no longer housed in Gloucester County. So the local on-site housing count should be treated as zero. Gloucester detainees are processed, classified, transported, and housed in partner facilities such as Salem, Atlantic, or Essex, depending on sex, status, and agreement.
This means the county's own Corrections Division now runs as a transport, classification, and bail-routing operation rather than a traditional county jail. Because housing is regionalized, the public roster and population statistics for Gloucester detainees may appear under partner facilities rather than a Gloucester jail count.
For anyone studying the county's jail numbers, this structure is the single most important fact. A standard question like "how many people are in the Gloucester County jail today" does not have a simple published answer, because there is no single jail to count. The honest figure for on-site local housing is zero, and the real detainee count is spread across the partner facilities that hold Gloucester's people under contract.
Gloucester County Jail Capacity Overview
Local capacity for on-site housing is effectively zero, since the county no longer houses offenders. Partner facility capacities are not published in the official Gloucester sources reviewed, so the table marks them as not located rather than guessing. Salem County Correctional Facility is named by the county as the main processing and housing facility.
| Facility / Function | Local Housing | Phone |
|---|---|---|
| Gloucester County Corrections (classification, transport) | No local inmate housing | 856-384-4607 |
| Salem County Correctional Facility | Main processing/housing per county | Not in county sources |
| Atlantic County Correctional Facility | Listed for female inquiries | Not in county sources |
| Essex County Correctional Facility | Listed for female inquiries | Not in county sources |
Confirm any partner-facility capacity directly with that county, since Gloucester's pages do not publish those numbers.
Average Daily Population and Data Gaps
The official Gloucester pages reviewed do not publish an average daily population, booking totals, or length-of-stay figures. Because housing is outsourced, the average daily count of Gloucester detainees must be requested from the county budget, the corrections contract, partner-jail invoices, or state reporting. It is not posted online.
A public records request to Gloucester Corrections or the County Commissioners can ask for the data that is missing online. A focused request gets a better answer than a broad one.
- Annual bookings of Gloucester detainees.
- Average daily population by housing facility.
- Total and per-diem jail housing expense by contract facility.
- Number housed by sex and the pretrial-to-sentenced split.
- Average length of stay and the annual jail and transport budget.
Demographic Context for Gloucester County
The county does not publish a jail demographic breakdown, so any figure here describes the county's general population, not its detainees. Census QuickFacts lists a Gloucester County population estimate of 311,783 as of July 2024, up from 302,294 in the 2020 census. These are residents, not inmates, and should not be read as jail statistics.
For jail-specific demographics, the Vera incarceration trends dashboard for New Jersey provides state-level figures and county comparisons. The county-population context below comes from the Census.
| County Population Measure | Value |
|---|---|
| Population estimate, July 2024 | 311,783 |
| Persons under 18 | 20.9% |
| Persons 65 and over | 17.9% |
| White alone | 80.5% |
| Black alone | 12.7% |
Pretrial vs Sentenced Population
Jail populations split into people held before trial and people serving a sentence. Pretrial detainees have not been convicted and are held while a case is pending. Sentenced inmates are serving time after a conviction. The mix matters because it shapes how long people stay and why they are held.
Vera's New Jersey dashboard, updated February 9, 2026, reports that 59% of the state's jail population is held pretrial and lists 114,523 annual local jail admissions statewide. These are state figures, not a Gloucester-only count, but they show how large the pretrial share is across New Jersey jails.
Note: The 59% pretrial share and 114,523 annual admissions are statewide New Jersey figures from Vera, not Gloucester County-only numbers.
Charge Levels in the Jail Population
New Jersey uses different terms than many states. Serious crimes are indictable offenses, roughly like felonies elsewhere. Lower-level matters are disorderly persons and petty disorderly persons offenses, closer to misdemeanors. Indictable cases are heard in the Superior Court, while disorderly persons cases are heard in municipal court.
A jail population usually mixes both, plus people held on violations or warrants. Gloucester does not publish a local breakdown by charge level, so the indictable-to-disorderly split for its detainees would have to be requested from the county or the housing facilities.
Mental Health and Medical Population
Jails carry a share of people with mental-health and medical needs, but Gloucester does not publish a local mental-health caseload for its detainees. Medical and mental-health information is protected by court rule, statute, and health privacy law, so individual data is not public. The county's Recovery Court and corrections alternatives, such as the Labor Assistance Program, reflect efforts to manage some of these needs outside a traditional jail.
For any mental-health population figures, the housing facilities and state agencies are the custodians. National context from BJS can frame the scale of the issue across jails. The county also lists a Juvenile Home Electronic Detention Program as a structured alternative to detention, which matters because juveniles are no longer housed in the county at all.
National and State Jail Data Context
National and state surveys help fill the gap left by missing local numbers. The Bureau of Justice Statistics publishes national jail population, demographics, admissions, and conviction-status data. Its preliminary 2024 jail data is a current national reference.
The BJS preliminary 2024 jail statistics set the national frame, while Vera adds the New Jersey view. The comparison below shows which level each source covers.
| Source | Level | What It Provides |
|---|---|---|
| Gloucester County records | County | No published local jail population; data by request |
| Vera incarceration trends | State | 59% pretrial; 114,523 annual NJ jail admissions |
| BJS jail data | National | National population, demographics, and admissions |
Population Trends Over Time
The clearest Gloucester trend is structural, not numeric. The county moved away from local inmate housing and now states that all male, female, and juvenile offenders are no longer housed in Gloucester County. The official pages reviewed do not publish a 2021 to 2026 series for daily population, bookings, or length of stay.
Because of that, third-party jail-population estimates should be treated with care unless they can be checked against official county budgets, partner-jail contracts, BJS, or Vera data. The honest picture is a county that shifted its model rather than a county with a rising or falling local count.
If you need a year-over-year trend for Gloucester detainees, the most reliable path is a records request for the per-diem housing expense and the average daily population by contract facility across several budget years. Those figures, read together, reveal the real trend better than any single estimate. Statewide trends from Vera can then show whether Gloucester's pattern matches or differs from New Jersey as a whole.
Searching for Gloucester County Inmate Records by Name
This page covers population data, not individual lookups. To find a specific person, use the name-based tools instead. State prison custody runs through NJDOC, federal custody through the BOP locator, and county routing through Gloucester Corrections. Full steps are on the Gloucester County inmate records page.
Where the Data Comes From
The numbers on this page trace to named sources. The no-local-housing facts come from the county Corrections and Female Offenders pages. The county-population figures come from Census QuickFacts. The pretrial share and admissions come from Vera's New Jersey dashboard. The national frame comes from BJS. Any figure missing from those sources is marked as not published, rather than estimated.
