How to Look Up Duval County Jail Population Data
Population figures for Duval County jails come from a small set of official sources. The Jacksonville Sheriff's Office publishes annual reports that describe the jail system and include intake and release counts. The corrections page on the Sheriff's site describes facility purpose and services. State-level and national-level data sets fill in context.
The data set splits into a few buckets. Bookings and releases are flow numbers, counted as events over a year. Capacity is a fixed number per facility. Average daily population is a snapshot, taken across each day of the year. Demographic breakdowns are slices through the daily population.
The Sheriff's Office annual report is the primary public document for year-by-year flow. The corrections page is the primary document for facility purpose. National context comes from the Bureau of Justice Statistics. State context comes from the Florida Department of Corrections statistics pages and from independent research groups that compile county-level jail data.
The Sheriff's corrections page is the central public reference for facility purpose, services, and the structure of the Duval County jail system.
Note: Population data changes year by year; cite the publication date of any number used in a public report or news story.
Duval County Jail Capacity Overview
The Sheriff's Office runs three corrections facilities. Each one holds a different category of inmate. The downtown jail is the largest, with a mixed pretrial and short-term sentenced population. The Community Transition Center holds county sentenced inmates in work and treatment programs. The Montgomery Correctional Center on the north side holds county sentenced inmates in a longer-term setting.
| Facility | Address | Stated Purpose | Capacity |
|---|---|---|---|
| Pre-Trial Detention Facility | 500 E. Adams St., Jacksonville, FL 32202 | Pretrial, federal, juvenile, state, and county sentenced inmates | Capacity figure not published on the public corrections page reviewed |
| Community Transition Center | 451 Catherine St., Jacksonville, FL 32202 | Work Furlough, Matrix House substance abuse treatment, inmate workers | Capacity figure not published on the public corrections page reviewed |
| Montgomery Correctional Center | 4727 Lannie Road, Jacksonville, FL 32218 | County sentenced and some sentenced male and female inmates | Capacity figure not published on the public corrections page reviewed |
The Sheriff's Office publishes facility purpose in plain language but does not list a hard capacity number on the public corrections page. Capacity figures for Florida county jails are filed with state and federal agencies on a periodic basis. Researchers using a specific bed count should request it directly from the Sheriff's Office public information staff and cite the document used.
Annual Bookings and Releases
Annual flow numbers tell a different story than capacity. A jail with a modest daily population can still process many thousands of people in a year. Most bookings end in a short stay. A small share end in a longer sentence served in the local system. The rest move to state prison, federal custody, supervision, or a dismissal.
The Sheriff's Office 2023 annual report includes a snapshot of the jail flow at the Pre-Trial Detention Facility.
| Metric (2023) | Reported Figure | Source |
|---|---|---|
| Inmates booked into the jail | Over 25,700 | JSO 2023 annual report |
| Inmates released | Approximately 28,000 | JSO 2023 annual report |
The release count runs ahead of the booking count for that year because some releases ended stays that began before 2023. The mix shifts year to year. Newer JSO annual reports continue the same intake and release reporting and should be consulted for the latest complete year.
Average Daily Population
Average daily population, often shortened to ADP, is a snapshot measure. It is the average number of people in custody across each day of the year. ADP captures the jail at rest, while booking and release counts capture the jail in motion. Both are needed for a full picture.
The Sheriff's Office corrections page reviewed for this site does not list a current ADP number for the Duval County jail system. ADP figures are typically published in the JSO annual reports and in state-level reporting from the Florida Department of Corrections. National-level ADP tallies appear in the Bureau of Justice Statistics annual jail reports, which roll up county-level data across the country.
For independent county-level data, the Vera Institute and similar research groups compile county jail figures from state and federal sources. Anyone citing a Duval County ADP in a published report should pull from the original JSO or BJS source and label the year clearly. Older ADP figures circulate online for many years after the source year, so the citation date matters.
Demographic Breakdown
Demographic detail breaks the inmate population into slices by race, sex, age, and offense category. A full breakdown shows the share of inmates by each category. These breakdowns are common in annual reports, in state-level publications, and in research-group data sets.
The official Sheriff's Office corrections page reviewed for this site does not include a detailed race, sex, age, or offense table for the Duval County jail population. The same information may appear in specific year annual reports, in city budget documents, or in records released through a public-records request. Reports based on the JSO 2023 annual report should cite the figures actually present in that document.
Where official county-level demographic data is not yet linked, the Florida Department of Corrections statistics pages give state-level demographic context for the sentenced population, and the Bureau of Justice Statistics gives national context. Both data sets are useful as benchmarks against any local figure that does become available.
Pretrial vs Sentenced Population
The Duval County jail system holds a mix of pretrial and sentenced inmates. The downtown jail is described on the corrections page as a facility for pretrial, federal, juvenile, state, and county sentenced inmates. The Community Transition Center and the Montgomery Correctional Center are described as facilities for county sentenced inmates in specific programs.
| Facility | Pretrial | County Sentenced | Other Holds |
|---|---|---|---|
| Pre-Trial Detention Facility | Primary use | Some county sentenced | Federal, juvenile, state holds |
| Community Transition Center | Not the primary use | Work Furlough and Matrix House program inmates | Inmate workers assigned to support roles |
| Montgomery Correctional Center | Not the primary use | County sentenced male and female inmates | Some sentenced male/female under JSO custody |
A precise pretrial-versus-sentenced ratio for the Duval County jail system was not located on the public corrections page reviewed. Ratio figures are often published in annual reports and in research-group data sets that pull from state sources. Anyone using a specific ratio should pull from a dated official document and cite that source.
Work, Treatment, and Health Programs
Some Duval County jail population data falls outside the standard demographic table. People assigned to Work Furlough, the Matrix House substance abuse treatment program, or inmate worker roles show up in different reporting categories than the general pretrial population. The corrections page describes those programs in plain terms.
Inmate health and mental health caseloads are also tracked separately. The corrections page lists medical and dental services, religious services, recreation, and other support across the facilities. Specific mental health caseload counts or medical caseload counts are not published on the corrections page reviewed. Annual reports and budget documents are the usual sources for those tallies.
Inmate workers cannot take visits during their assigned work hours. Juveniles cannot take visits during school hours. Both rules show that the population is segmented for daily scheduling, not just for housing.
State and National Population Context
State and national context helps compare Duval County to other places. The Florida Department of Corrections publishes statewide statistics for the sentenced prison population, which sits on top of all county jail populations across Florida. The Bureau of Justice Statistics publishes national jail and prison statistics that put state numbers in a national frame.
National jail rates per 100,000 residents change slowly year over year. Florida tracks above some states and below others. Comparing a Duval County rate to a Florida rate and a national rate is the standard frame for reporting. The Vera Institute and similar groups publish county-level series that allow direct comparison across counties.
For accurate citation, the year matters. A 2023 figure should be compared to other 2023 figures. Older comparisons drift quickly as reform programs, court backlogs, and arrest patterns shift.
Population Trends Over Time
Population trends are tracked through a multi-year window. A jail system can hold a stable average daily population while its annual booking count rises or falls. The two metrics move on different cycles. Pretrial reform programs, court calendar shifts, and arrest pattern changes all show up in the trend lines.
Duval County trend tables are best pulled from the Sheriff's Office annual reports across several recent years. The 2023 annual report gives one anchor point for bookings and releases. Earlier and later reports give the trend. National and state context comes from the same BJS and FDC sources used elsewhere on this page.
Public-interest research groups also publish county-level trend charts. The Vera Institute, the Prison Policy Initiative, and academic centers track jail populations across many counties. Their pages are useful for trend comparison but should be checked against the original JSO and state data for the most accurate Duval County numbers.
Searching for Inmate Records by Name
Population data is a system-level view, not a person-level view. To look up a specific person by name in the Duval County jail roster, the right tool is the JSO Inmate Information Search. Step-by-step instructions, search fields, and profile field details live on the inmate records page. For people who have been released, the released inmates page covers the release log, state and federal sources, and notification setup.
Where the Duval County Jail Population Data Comes From
Source citations are the backbone of any population analysis. The Sheriff's Office is the originating authority for Duval County jail data. The Florida Department of Corrections is the originating authority for state prison data. The Bureau of Justice Statistics is the originating authority for national jail and prison data. Each source has its own publication schedule and its own format.
The Sheriff's Office contact page lists the public lines for general information, jail information, and emergency response. Open-records requests for population data go through the Sheriff's Office public information staff. Specific annual reports may also be archived on the Jacksonville city website and through the city's open data portal where available.
The Sheriff's contact page is the right starting point for population-data questions, public-records requests, and confirmation of the latest annual report year.
- JSO annual reports for year-by-year intake, release, and program data.
- FDC statistics pages for state prison context and sentenced population.
- BJS annual jail and prison reports for national context.
- Vera Institute and similar research groups for cross-county comparison.
- Florida open-records requests for specific data not posted online.
Note: Always confirm a number against the dated original document before publishing or citing it.
