The Nassau County Inmate Population
The Nassau County inmate population is held at the Nassau County Jail & Detention Center in Yulee, run by the Nassau County Sheriff's Office Division of Corrections. The jail takes in adults arrested anywhere in the county. It holds people before their first court appearance, people waiting for a case to be resolved, people serving short local sentences, and people waiting to be moved, bonded out, or released. The Florida Department of Corrections collects a monthly count from each county and publishes it. In the FDC County Detention Facilities Average Inmate Population report for October 2025, the Nassau County Jail had an average daily population of 249.
That number is not fixed. The size of the Nassau County inmate population rises and falls with arrest volume, how fast cases move through court, and bond decisions. When a felony case ends in a prison sentence, the person leaves the county jail and joins the state prison count instead, so the local total and the statewide total track different slices of custody. A booking adds to the count; a release, a bond, or a transfer takes one away. Because of this churn, the daily roster and the monthly average tell two different stories about the same jail.
Nassau County Inmate Population Statistics
The clearest official figures for the Nassau County inmate population come from the Florida Department of Corrections County Detention Facilities Average Inmate Population report for October 2025. That report lists an average daily population of 249, a county population of 103,990 used for the rate calculation, and an incarceration rate of 2.4 per 1,000 county residents. A rated bed capacity was not published in the official sources reviewed, so the stat card below shows it as not published rather than guessing a number.
The figures below set the Nassau County inmate population next to the wider state count for context. Nassau is a small share of Florida's jail population, but its incarceration rate sits a hair above the statewide county-detention rate for the same month. The pretrial figures are the most telling part of the picture, since most people in the jail have not yet had their cases resolved.
| Measure | Figure | Source / Year |
|---|---|---|
| Average daily population | 249 | FDC County Detention Facilities report, October 2025 |
| Rated / bed capacity | Not published in official sources | NCSO pages reviewed, 2025 |
| County population (rate base) | 103,990 | FDC October 2025 report (UF BEBR estimate) |
| Incarceration rate | 2.4 per 1,000 | FDC County Detention Facilities report, October 2025 |
| Statewide incarceration rate | 2.3 per 1,000 | FDC County Detention Facilities report, October 2025 |
| County share of state jail ADP | 0.47% | FDC County Detention Facilities report, October 2025 |
Nassau County Inmate Population Trends
Tracking the Nassau County inmate population over several years would normally call for a row of yearly averages. The strongest official source located is a single clean snapshot, the FDC County Detention Facilities report for October 2025, which gives the county jail an average daily population of 249. Older Nassau-specific averages were not pulled from official monthly FDC reports for this build, so the table does not invent prior-year county figures. What can be shown honestly is the October 2025 Nassau row alongside the statewide totals that the same report series carries for context.
| Period | Average Daily Population | Scope / Notes |
|---|---|---|
| October 2025 | 249 | Nassau County Jail, FDC county detention report |
| October 2025 | 197 pretrial | Nassau County, 164 felony plus 33 misdemeanor pretrial |
| 2025 statewide (Jan-Oct avg) | 54,327 | Florida county detention grand total, statewide context only |
| October 2025 statewide | 53,245 | Florida county detention total, statewide context only |
Note: only the October 2025 rows describe the Nassau County jail directly; the statewide rows are added for scale and are not Nassau-specific.
Who Makes Up the Nassau County Inmate Population
The Nassau County inmate population is mostly pretrial. In the October 2025 FDC report, 164 people were held as felony pretrial detainees and 33 as misdemeanor pretrial detainees. Together that is 197 pretrial inmates out of an average daily population of 249, a pretrial share of 79.1%. In plain terms, roughly four out of five people counted in the jail that month were waiting for a case to be resolved rather than serving a final local sentence. A pretrial detainee is someone held before the case ends, often because bond has not been posted or no bond was set.
- Pretrial vs sentenced - 197 of the 249 average daily inmates were pretrial, or 79.1%, in October 2025.
- Felony pretrial - 164 inmates were held on felony charges awaiting case resolution.
- Misdemeanor pretrial - 33 inmates were held on misdemeanor charges awaiting case resolution.
- Sentenced felons - people sentenced to state prison leave the county count and appear in the Florida Department of Corrections system instead.
The same FDC report does not break out the Nassau County inmate population by sex, race, or age, so those splits are left out rather than estimated. Statewide, the report shows most county-jail inmates are adult males, but those totals describe Florida as a whole and not Nassau County on its own.
Nassau County Jail Capacity and Overcrowding
A jail's rated capacity is the number of beds it is approved to hold. For the Nassau County Jail & Detention Center, that number was not published in the official sources reviewed for this build. The Nassau County Sheriff's Office pages that were checked describe intake, housing, and inmate programs, but they do not list a rated bed count. Third-party sites circulate bed-count figures, but those are not official records and are not used here.
Because no verified capacity was located, the jail's October 2025 average daily population of 249 cannot be measured against an official limit, so this page does not claim the jail is or is not overcrowded. No official overcrowding lawsuit, consent decree, new-jail construction plan, or death-in-custody report for the Nassau County Jail was located in the official sources reviewed. If the county later publishes a jail inspection, capital plan, or budget document with a verified bed count, that figure would belong in the stat card and this section.
Laws Governing the Nassau County Inmate Population
Several Florida statutes set the rules behind the data on the Nassau County inmate population. One defines county jails and the standards they run under, including the monthly reporting instrument that feeds the state's county detention population reports. Others make jail and booking records open to the public and spell out how to inspect or copy them. Reading the count alongside these laws explains why the numbers exist and why the public can see them.
Key Statutes:
Florida Statutes § 951.23 - Defines county and municipal detention facilities, requires operators to adopt the Florida Model Jail Standards, and supports the monthly population reporting used in the FDC county jail reports.
Florida Statutes Chapter 119 - The state Public Records Law, which makes records made or received by the sheriff and the jail open for inspection unless a specific exemption applies.
Florida Statutes § 119.07 - Sets out how the public may inspect and copy public records, including the fees and process an agency may use.
Together these statutes are why a county can report a jail population at all and why a member of the public can request a booking record. The reporting law standardizes how each county counts inmates, and the public-records law gives anyone the right to ask the sheriff's office for jail records that are not posted online.
Nassau County and the State Prison Population
The county jail count and the state prison count are not the same population. The Nassau County Jail holds people before and during their cases and those serving short local time. When a Nassau County felony case ends in a state prison sentence, that person leaves the county jail and is admitted to the Florida Department of Corrections, the statewide prison and supervision agency. From that point, the person is tracked through the FDC system, not the county roster.
The Florida Department of Corrections runs the public locator for sentenced state prisoners and people under state supervision. Its search specifically excludes anyone held in a county jail, on county probation, or under other local supervision, which keeps the two counts separate. No state prison is located inside Nassau County, so a person sentenced from a Nassau case is held at an FDC facility elsewhere in the state. After sentencing there can be a short gap when the person still appears in county custody while awaiting transfer to an FDC reception center.
How to Search the Nassau County Inmate Population
The Nassau County Sheriff's Office links an online inmate search from its Corrections page as the public way to check current custody. The sheriff's office describes the search as showing current in-custody status and bond information. The portal could not be inspected directly for this build because it returned a web application firewall block, so the exact on-screen fields are not promised here. The safe approach is to open the official search and follow the labels shown on the live page rather than expect a specific form.
Before starting, have the person's full name ready. A booking or case number helps if you have it, but a name is usually enough to begin. If the person was arrested very recently, intake may not be finished, and a phone call to the booking desk is the better first step.
- Open the official NCSO inmate search at the Nassau County Sheriff's Office inmate inquiry portal and follow the search labels the page displays.
- Enter the inmate's name as shown on the official page, using the exact name from any arrest notice if you have it.
- Review the result for current in-custody status and bond information, the fields the sheriff's office confirms the search provides.
- If the search is down or the person is not listed, call the booking desk at 904-548-4006 for processing and bond questions.
- If the person may already be sentenced to state prison, switch to the Florida Department of Corrections locator, since the county search will not show state custody.
Current Inmate Lookup in Nassau County
A current inmate lookup in Nassau County starts at the sheriff's online inmate search. The most direct way to reach it is from the official Corrections page, which links the live roster used for the county jail. The lead-in to the portal below points to that official search so readers can confirm they are using the real source rather than a third-party copy.
The sheriff's office identifies the inmate inquiry portal at its New World inmate search page as the public county jail roster.
The search returns current custody and bond details for people held in the county jail, which is the slice of the Nassau County inmate population that a roster lookup covers. Because the live portal could not be inspected for this build, the field table below records what the sheriff's office confirms and tells you to read the rest from the labels on the official page itself.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Inmate name | Text | Follow on-screen label | Portal was firewall-blocked from inspection; use the exact name fields shown on the official NCSO page. |
| Current in-custody status | Result output | n/a | Confirmed by the sheriff's office as part of the online inmate search. |
| Bond information | Result output | n/a | Confirmed by the sheriff's office as part of the online inmate search. |
Note: do not assume the county roster shows mugshots, charges, or housing until you confirm those fields on the live official portal.
Past and Released Inmate Records
Finding someone who is no longer in custody works differently from a current lookup. The county online inmate search is built to show people in the jail now, and the sheriff's office does not publish how long a released name stays visible or how far back the roster reaches. For a booking that is no longer online, the route is a public-records request to the sheriff's office for the historical booking record.
The Nassau County Sheriff's Office Records Department handles those requests through its JustFOIA online records portal or in person at 77151 Citizens Circle in Yulee. Including the case number, the date and time, the incident location, the deputy's name, and the names of anyone involved helps the records staff find the file faster. If the person was sentenced to state prison after a Nassau case, the past record path is the state corrections locator instead, since released and scheduled-to-release state inmates appear there rather than on the county roster.
What a Nassau County Inmate Record Shows
The Nassau County Sheriff's Office confirms that its online inmate search provides current in-custody status and bond information. It does not publish a full list of every field on a roster result, and the live portal could not be inspected for this build. For that reason the table below only states what the sheriff's office confirms and what its booking process documents, and it does not promise fields such as a photo or housing unit that were not verified.
| Field | What It Shows |
|---|---|
| Current in-custody status | Whether the person is held in the county jail right now, confirmed by NCSO as part of the inmate search. |
| Bond information | The bond tied to release, confirmed by NCSO as part of the inmate search. |
| Intake status | A person is not considered for release or visitation until property inventory, booking, medical screening, and cell assignment are complete. |
| Release processing | Cleared inmates return to the booking desk for property, monies, and bond steps; release times vary. |
| Cash bond | Paid by certified or cashier's check from a local bank or money order to the Nassau County Clerk of Courts; no cash or credit cards. |
| Purge | A civil release amount, such as on a writ of attachment, paid by certified check or money order to the Nassau County Sheriff's Office. |
County Jail vs State Prison: Where to Look
The single most common mistake in an inmate search is using the wrong system. Pretrial detainees and people serving short local sentences sit in the Nassau County Jail and show up on the sheriff's roster. People sentenced to state prison on a felony move to the Florida Department of Corrections, a separate agency with its own locator. The comparison below shows which part of the inmate population each system covers so you start in the right place.
| County Jail | State Prison (DOC) | |
|---|---|---|
| Who Is Held | Pretrial detainees and short local sentences | Sentenced felons |
| Run By | Nassau County Sheriff's Office | Florida Department of Corrections (FDC) |
| Where to Look | NCSO online inmate search | FDC offender search |
| What It Confirms | Current custody status and bond information | Location, DC number, offenses, release date |
A useful way to remember the split is the custody flow: arrest leads to booking, then a first appearance, then the county jail, and if the case ends in a prison sentence, transfer to state DOC custody. Up to the prison step, the county roster is the source. After it, the state locator is.
State and Federal Inmate Search
When the county roster is not the right tool, three other locators cover the rest of the inmate population. The Florida Department of Corrections runs the search for sentenced state prisoners and people under state supervision. The lead-in below points to the FDC current inmate population search, the page used after someone leaves the Nassau County Jail for state prison.
The Florida Department of Corrections publishes its inmate population information search for current state prisoners.
The FDC search lets you look by last name, first name, or DC number, with options to include aliases and control photo display. The DC number is a six-character state identifier, either all numbers or one letter followed by five numbers. For federal custody, the Federal Bureau of Prisons inmate locator covers people in federal prison, and the ICE online detainee locator covers immigration detention. Where a participating agency provides data, VINELink can return custody status as a fallback, though it is supplemental and not the official county roster. The official Nassau County Sheriff app may include inmate-search access, but the web roster and booking desk remain the primary sources, so verify current app availability before relying on it.
Nassau County Detention Facilities
Two facilities account for the local custody picture in Nassau County, and they serve very different groups. The adult jail holds the Nassau County inmate population covered by the sheriff's roster. A regional juvenile center in Jacksonville serves Nassau County youth under a separate state system, with records that are far more restricted than adult jail records.
- Nassau County Jail & Detention Center - the county adult jail in Yulee, holding pretrial detainees, people serving short local sentences, and those awaiting transfer or release.
- Duval Regional Juvenile Detention Center - a state juvenile detention center in Jacksonville that serves Duval, Clay, and Nassau youth; it is not an adult jail and uses separate juvenile-court channels.
Nassau County Inmate Population Terms
A few terms come up again and again when reading about jail custody and the inmate population. Knowing them makes a roster result and the official statistics easier to understand.
- Pretrial detainee
- A person held before a case is resolved, often because bond was not posted or no bond was set.
- Average daily population (ADP)
- The average number of inmates held per day over a reporting period, the figure FDC uses for the county jail.
- Bond
- Money or conditions set to secure release and a promise to return to court.
- Purge
- A civil payment, often tied to a writ of attachment, that must be paid for release.
- Detainer
- A hold placed by another agency, such as another county, the state, federal authorities, or immigration.
- FDC
- The Florida Department of Corrections, the state agency for prison and supervision custody.
Nassau County Inmate Population FAQ
How big is the Nassau County inmate population?
In the Florida Department of Corrections County Detention Facilities report for October 2025, the Nassau County Jail had an average daily population of 249. That count placed the county at an incarceration rate of 2.4 per 1,000 residents, slightly above the statewide county-detention rate of 2.3 per 1,000 for the same month. The number changes daily as people are booked, bond out, or move to state prison, so the monthly average is a snapshot rather than a fixed figure.
How do I search the Nassau County inmate population?
Use the official Nassau County Sheriff's Office online inmate search linked from its Corrections page. The sheriff's office says the search shows current in-custody status and bond information for people held in the county jail. Have the person's full name ready. If the search is down or the person is not listed, call the booking desk at 904-548-4006, since a very recent arrest may still be in intake.
Is the Nassau County inmate search the same as the Florida DOC search?
No. The Nassau County search covers local jail custody and bond information. The Florida Department of Corrections search covers felony offenders sentenced to state prison or state supervision, and it specifically excludes county jail and county probation records. Someone arrested recently belongs in the county search, while someone sentenced to state prison belongs in the FDC locator.
Why is a recent arrest not showing up?
The jail must complete property inventory, booking, medical screening, identification clearance, and cell assignment before a person is considered for release or visitation. A very recent booking can lag online during that process. If the online search is not enough, call the booking desk at 904-548-4006 for processing and bond questions.
Can I look up a released or past inmate?
The county online search is built for current inmates, and the sheriff's office does not publish how long a released name stays visible. For an older booking record, file a public-records request with the Nassau County Sheriff's Office through its JustFOIA portal or in person, including identifying details. If the person was sentenced to state prison, the FDC locator lists released and scheduled-to-release state inmates instead.
Are Nassau County mugshots online?
This could not be confirmed because the official portal blocked automated inspection, so the live roster's photo fields are unknown. Start with the official NCSO inmate search to see what it displays. If a booking photo is not shown or the portal is unavailable, a public-records request to the sheriff's office is the route. Booking photos for current inmates are covered on the Nassau County jail mugshots page.
