The Jefferson County Inmate Population
The official detention map for Jefferson County resolves to one public jail facility: Jefferson County Jail, operated by the Jefferson County Sheriff's Office. The jail is the county intake, custody, and work-release site. It is also a place where outside custody can appear in the daily count. The county jail statistics page says the facility houses Jefferson County inmates, Wisconsin State Prison System inmates, Federal Bureau of Prisons inmates, East and West District U.S. Marshals inmates, and inmates from surrounding counties. That mix makes the Jefferson County inmate population a physical custody count, not just a list of local criminal cases.
For a searcher, that distinction matters. A person may be in a Jefferson County jail bed while the court case is from another county or a federal hold. Another person may have left the jail after sentencing and moved into Wisconsin Department of Corrections custody. The local jail count, the public roster path, WCCA court cases, and the DOC locator each answer a different part of the question. Reading them together gives a cleaner view of the Jefferson County inmate population and the record trail behind it.
Jefferson County Inmate Population Statistics
The Jefferson County Jail Statistics page, accessed July 3, 2026, gives the strongest local population data. It lists 229 total beds, split into secure custody and Huber work-release beds. The same county source gives an average total inmate population range of 145 to 160 and says about 60 people use Huber privileges. These figures are more useful than a single bed number because the secure POD and the Huber dormitories serve different custody groups.
| Measure | Figure | Source / Date |
|---|---|---|
| Average total inmate population | 145-160 | Jefferson County Jail Statistics, accessed July 3, 2026 |
| Rated bed capacity | 229 beds | Jefferson County Jail Statistics, accessed July 3, 2026 |
| Secure POD beds | 116 beds | Jefferson County Jail Statistics, accessed July 3, 2026 |
| Huber/work-release beds | 103 beds | Jefferson County Jail Statistics, accessed July 3, 2026 |
| Huber population | About 60 inmates | Jefferson County Jail Statistics, accessed July 3, 2026 |
The county does not publish annual bookings, average length of stay, sex, age, race, or felony and misdemeanor splits in the static sources reviewed. Those gaps should not be filled with estimates. The published figures are still enough to show the main local pattern: the Jefferson County inmate population is shaped by a large work-release program and a secure side that can hold county inmates and contracted inmates.
The county's own jail statistics page is the source for the capacity split, average range, and Huber count used here.
The screenshot is useful because it ties the Jefferson County inmate population numbers to the county jail's official statistics page rather than a third-party roster site.
Jefferson County Jail Capacity
Using the county's own average range, the jail is below its total rated capacity. A 145-person average is about 63 percent of the 229-bed rating, and a 160-person average is about 70 percent. Those are calculations from official county numbers, not separate county-published rates. The key caution is that total capacity is not one pool of identical beds. A secure POD bed is not the same operational resource as a Huber dormitory bed.
The POD side is described by Jefferson County as maximum security. It houses county inmates and contracted inmates. Dormitories house minimum-security inmates using work release, educational release, and home-care privileges. The Huber share is large: about 60 people out of the average range means roughly 38 to 41 percent of the jail's average count is tied to work-release privileges. That is a defining fact for the Jefferson County inmate population.
The research file did not locate an official recent consent decree, construction plan, county jail death report, or overcrowding litigation in the reviewed county sources. The county's own current figures and facility descriptions are the safe basis for capacity analysis.
Who Is Held in Jefferson County
Jefferson County Jail holds more than local pretrial detainees. The county jail statistics page identifies several custody sources, including Wisconsin State Prison System inmates, BOP inmates, U.S. Marshals East and West District inmates, surrounding-county inmates, and Jefferson County local inmates. A roster or VINE result can therefore point to the jail as the physical location while the legal authority is local, state, federal, or from another county.
- Local county custody: people booked after Jefferson County arrests, court holds, or county sentences.
- Huber/work release: minimum-security sentenced inmates approved for work, education, or home-care privileges.
- State custody: people connected to Wisconsin DOC custody who may be housed or transferred through the county jail.
- Federal custody: BOP or U.S. Marshals inmates physically held at the jail under outside authority.
- Surrounding counties: people held for nearby jurisdictions when the county accepts them.
Note: A person physically held in Jefferson County Jail may still need a DOC, BOP, ICE, or WCCA search to explain the legal case.
Laws Governing Jefferson County Inmates
Wisconsin law helps explain why some jail facts are public and why other details can be withheld. Wisconsin Stat. 19.31 states the public-records policy in broad terms, while Wisconsin Stat. 19.35 covers access and fees. Those laws apply with exceptions and a balancing test, so public access does not mean every booking detail, photo, video, or security fact must be posted online.
Key Wisconsin rules:
Wis. Stat. 59.27 places the county jail and prisoner register duties with the sheriff.
Wis. Stat. 302.365 requires jail program standards and written policies for screening and programming.
Wisconsin Admin. Code DOC 350 sets minimum standards for jail design, construction, and operation.
Classification also matters. Wisconsin Stat. 302.36, surfaced in the jail statutes around Wisconsin prisoner reimbursement law, requires an objective prisoner classification system. Jefferson County's published POD and dormitory terms line up with that concept. Housing is based on risk, behavior, legal status, medical or mental-health concerns, and safety needs, not just bed availability.
How to Search Jefferson County Inmates
Jefferson County does not publish a plain static jail roster table in the county pages reviewed. The county links custody and criminal-case lookup to Wisconsin VINELink, and the 2026 JESO app press release says the sheriff's mobile app includes detailed jail and inmate lists. A practical Jefferson County inmate search starts with those two public channels, then uses phone and records-request routes when the online path is thin.
- Start at the Jefferson County Sheriff's Office or Jail Division page and open the county-linked VINELink custody lookup.
- Search by name in Wisconsin VINE. If an agency or county filter appears, use Jefferson County or the Jefferson County Sheriff's Office.
- Use the JESO mobile app when mobile access is available, since the county press release says the app includes jail and inmate lists.
- If the person does not appear, call the Jail Division at 920-674-8620 or the Sheriff's Office at 920-674-7310.
- For booking records, mugshots, incident reports, or older records, use the Sheriff's open-records process.
The JESO launch is unusually important for Jefferson County. The county press release announcing the app says Sheriff Travis Maze linked early demand to easier access to jail and inmate list information. The app also lists outstanding warrants, sex offenders, sheriff sales, crash reports, records-request access, tips, and public-safety alerts.
Jefferson County VINELink Lookup Fields
VINELink is a vendor portal, and the exact field labels can change. The static research captured the county's use of Wisconsin VINE for custody status and criminal-case lookup, but it did not capture a full live inmate profile. Use cautious results language. VINE is strong for status and notifications. It may be thinner than a jail booking record.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| State | Dropdown or state landing | Yes | Use Wisconsin from the VINE landing path. |
| Search type | Tab or dropdown | Unspecified | Jefferson County names custody status and criminal-case lookup. |
| Name | Text | Usually yes | Search by person name; spelling differences can affect results. |
| ID or case number | Text | Optional when offered | Use a known offender number or case number if the portal exposes that path. |
| County or agency | Dropdown/filter | Optional if exposed | Narrow to Jefferson County or Jefferson County Sheriff's Office when available. |
What Jefferson County Records Show
A Jefferson County inmate record may not show the same fields in each system. VINELink is built around custody status and notification. The JESO app may show a jail list, but the public app-store pages do not confirm all booking fields. WCCA shows court charges once the prosecutor files a case. DOC and BOP locators use their own identifiers. A careful search treats each system as a separate record source.
| Field | Research Status |
|---|---|
| Name | Expected in VINE and app custody lookup; exact display format was not captured. |
| Custody status | VINE is designed for status and notification, and the county links it for custody lookup. |
| Holding agency | May show Jefferson County or another holding agency when exposed. |
| Charges | Check WCCA for formal charges because the DA decides what to file. |
| Mugshot | Not confirmed on static county roster sources; request through open records if not visible. |
| Release or transfer | VINE is the main public channel for release and transfer notification. |
County Jail and State Prison Search
The Jefferson County inmate population should not be confused with the Wisconsin prison population. The Wisconsin DOC general information page says its locator is for people sentenced to state prison and housed in DOC custody. DOC also notes that people not found there may be held in a city or county jail administered separately. That is why a fresh Jefferson County booking belongs in VINE, JESO, or jail records first, while a sentenced prison case belongs in the Wisconsin DOC Offender Locator.
| Custody Type | Best Lookup | What It Covers |
|---|---|---|
| Jefferson County jail | VINELink, JESO app, Jail Division | Current local custody, Huber, and county jail status. |
| Wisconsin state prison | DOC Offender Locator | Sentenced prison and supervision records. |
| Federal custody | BOP Inmate Locator | Federal inmates from 1982 to present, mainly sentenced BOP custody. |
| Immigration detention | ICE Online Detainee Locator | Immigration detainee searches by A-Number or biographical details. |
The county jail can house BOP and U.S. Marshals inmates, so the federal locator is not filler here. A federal defendant may be physically in Jefferson County Jail while the underlying case belongs to federal court. BOP may not show every pretrial U.S. Marshals hold the same way it shows sentenced BOP custody.
Open Records for Jefferson Inmates
The Sheriff's open-records process is the fallback when VINE or the app does not show enough detail. The Jefferson County Sheriff's Open Records page lists Sheriff Travis Maze as legal custodian of Sheriff's Office records. Requests can be made through the online form, by detailed email to openrecords@jeffersoncountywi.gov, or by mail or drop-off to the Sheriff's Office at 411 South Center Avenue. The county asks for names, locations, dates, times, incident type, and officer names if known.
Phone calls cannot be used to request records. The county does allow records questions at 920-674-7329. Requested items must be paid by cash or check because the office says it cannot process credit or debit cards for those items. If a requester does not respond within 30 days after notice that the request is complete, the county marks the request as no response and archives it. Video can take longer.
Jefferson County Detention Facility
Only one public detention facility becomes a facility page for this project. City police departments may make arrests or operate stations, but the official sources reviewed did not identify a separate public municipal jail page in Jefferson County. The county jail remains the central public custody point.
- Jefferson County Jail - the county jail, secure POD, and Huber/work-release facility for Jefferson County inmates and several outside-agency custody categories.
The facility's local details are unusually specific. Jefferson County publishes the secure and Huber bed split, the average population range, and precise Huber fees and documentation rules. That information gives the facility page more value than a generic address listing.
Jefferson County Custody Terms
Common jail and court terms can point to different systems. These definitions keep Jefferson County inmate search results in the right lane.
- Huber
- A Wisconsin work-release privilege that can let eligible sentenced inmates leave for approved work or care obligations.
- POD
- Jefferson County's secure jail housing side, described by the county as maximum security.
- Detainer
- A hold or request from another agency that can keep a person in custody after a local issue is addressed.
- Body-only warrant
- A Jefferson County warrant term meaning the person must be seen by a judge rather than simply paying cash bond.
- WCCA
- Wisconsin Circuit Court Access, the court case-search system used to review charges and case activity.
Jefferson County Inmate Population FAQ
How large is the Jefferson County inmate population?
The county jail statistics page lists an average total population of 145 to 160 people and a total rated capacity of 229 beds. Those figures were accessed July 3, 2026. The total includes secure and Huber/work-release custody, and the county also notes that the jail can house outside-agency inmates.
How do I search for Jefferson County inmates?
Start with Wisconsin VINELink from the Sheriff's or Jail Division page. Use the JESO mobile app if mobile access is available, because the county press release says it includes jail and inmate lists. If neither path works, call the Jail Division or use the Sheriff's open-records process.
Does the jail roster include state prison inmates?
No single roster covers every custody type. A sentenced person in Wisconsin DOC custody belongs in the DOC Offender Locator. A person physically held at Jefferson County Jail under an outside hold may also require WCCA, BOP, ICE, or another county's records.
Can released inmates be searched?
The county pages reviewed do not publish a retention period for released inmates in VINE or the app. For older booking records, use the Sheriff's open-records process and provide as much identifying detail as possible.
