The Marathon County Inmate Population
The core Marathon County inmate population is held through the Marathon County Sheriff's Office Corrections Division. The adult jail is the main local detention site, while the Marathon Juvenile Detention Facility is a separate secure juvenile placement. The adult jail serves arrests from Wausau, municipal police departments, the sheriff's office, state patrol activity in the county, and other agencies accepted by the jail. That makes the county jail roster broader than a simple list of sheriff arrests.
The public count also needs context. The official P2C roster returned 251 records when inspected on July 3, 2026, but that figure should not be treated as a bed count by itself. The holding-facility filter included Marathon County Jail, Home Monitor, Dane County (Fed), Mendota, Taylor County Jail, and Waupaca County Jail. A person may be supervised by Marathon County, held for another agency, housed out of county, or serving under electronic monitoring rather than sitting in a physical jail cell.
Marathon County Inmate Population Statistics
Marathon County publishes firm facility numbers for the adult jail and juvenile detention facility. The adult jail opened in 1988, received a 120-bed addition in 2000, and is listed by the county with 279 beds. The juvenile facility is listed with capacity for 20 children ages 10 to 17. The local research did not locate an official annual booking count or an extractable county average daily population table, so those figures should not be guessed.
| Measure | Figure | Source / date |
|---|---|---|
| Adult jail rated capacity | 279 beds | Marathon County Corrections Division, inspected July 3, 2026 |
| P2C live roster total | 251 records | Official P2C API response, July 3, 2026 |
| Juvenile facility capacity | 20 children ages 10-17 | Marathon County Corrections Division |
| National jail benchmark | 664,200 local jail inmates at midyear 2023 | Bureau of Justice Statistics Jail Inmates in 2023 |
| Wisconsin incarceration context | 615 per 100,000 residents | Prison Policy Initiative Wisconsin profile |
Marathon County Jail Population Trends
The strongest official trend line is facility history: the jail opened in 1988, then added 120 beds in 2000. More recent local reporting gives useful context but must be attributed as news, not as the official population table. PBS Wisconsin reported that on July 25, 2023, Marathon County had 131 people in its facility and 117 housed elsewhere during a period of Wisconsin jail staffing strain. Other local reporting described past overcrowding and a COVID-era population drop, but those figures were not found in a current county data table.
| Date | Figure | What it means |
|---|---|---|
| 1988 | Jail opened | Official adult jail history |
| 2000 | 120-bed addition | Official expansion history |
| July 25, 2023 | 131 in facility, 117 elsewhere | PBS Wisconsin reporting with Sheriff Chad Billeb |
| July 3, 2026 | 251 P2C records | Official public roster response, with home monitor and other holding statuses included |
Who Is in Marathon County Custody
The public roster does not publish a full demographic report for the Marathon County inmate population. It does show the categories a user can search or filter. Race filters include Black or African American, White or Caucasian, Asian/Pacific Islander, Native American, and Hispanic. Sex filters include Male, Female, and Unknown. Age is a numeric filter and a visible public field, while date of birth and home address are hidden in public roster settings.
The custody mix is local and practical. The adult jail population can include people awaiting initial appearance, people with pending court dates, sentenced county inmates, people on home monitor, and people held for another Wisconsin or U.S. agency. Juvenile detention is not part of the adult inmate roster. Sentenced prison cases move to the Wisconsin DOC locator, and federal or immigration custody must be checked through federal systems.
- Pretrial detainee
- A person held after arrest while charges, bond, or court dates are pending.
- Home Monitor
- A jail-supervised electronic monitoring status that can appear in Marathon County roster filters.
- Detainer
- A hold or request from another agency that can affect release even when local bond is addressed.
- DOC
- The Wisconsin Department of Corrections system for sentenced prison custody and supervision.
Marathon County Jail Capacity
The adult facility's official rated capacity is 279 beds. If the July 3, 2026 P2C total of 251 records were compared directly against that capacity, the simple ratio would be about 90 percent. That comparison has a major caveat: the roster includes a holding-facility filter for Home Monitor and other locations, so it is not the same as in-house bed occupancy. For a true bed count, the holding facility and current custody status matter as much as the roster total.
Population caveat: The roster total is a public search count, not a certified in-house bed census.
Laws Governing Marathon County Records
Wisconsin law supplies the public-record framework for jail and booking information, while DOC rules govern jail standards. These laws do not mean every data point must be posted online. They do mean that a requester can usually start with public access and then use the county records process when an item is not visible on the roster.
Key statutes and rules:
Wis. Stat. 19.31 states Wisconsin's policy favoring public access to government records.
Wis. Stat. 19.35 gives the general right to inspect records and request copies, subject to limits.
Wis. Stat. 19.36 explains limits that can restrict release, including other law and public-policy balancing.
Wis. Admin. Code ch. DOC 350 sets jail standards for local detention operations, records, health screening, security, mail, visitation, and canteen.
Search the Marathon County Inmate Population
The official current roster is the Marathon County Sheriff's Office Police-to-Citizen Inmates Catalog. It is free, public, and no login was observed in the research pass. The roster is the first place to search for a current adult jail record, including a person in the courthouse jail, Home Monitor, or another listed holding location tied to Marathon County supervision.
The roster is not the right source for every person. If the person was sentenced to Wisconsin prison, use the Wisconsin DOC Offender Locator. If the person is in federal custody, check the BOP inmate locator. If immigration custody is involved, use ICE ODLS. For custody alerts, Wisconsin VINE is available at VINELink.
- Open the P2C Inmates Catalog and start with the broad search bar.
- Use last name first, then add first name only if the results are too broad.
- Open Advanced search when age, charge, arrest date, race, sex, or holding facility can narrow the result.
- Expand the inmate card to review charges, bond, court date, booking agency, and holding facility.
- If no record appears, clear filters and check DOC, VINE, BOP, ICE, or the county records portal.
The official roster screenshot in the manifest comes from the P2C inmate roster interface, which is the same search channel described above.
The screenshot shows why a name-only search can miss context: the interface supports search, filters, sort controls, and expandable inmate cards.
Marathon County Roster Search Fields
The P2C roster exposes useful search fields through the official search-criteria API. None of the advanced fields was marked as required in the research. That helps when a user has only a last name, but it also means a careful search should be widened before assuming a person is not in custody.
| Field label | Type | Required | Notes |
|---|---|---|---|
| Global search bar | Text | No | Broad name or keyword search above the catalog |
| Last Name | Text | No | Best first structured field for name lookup |
| First Name | Text | No | Useful after a last-name search returns too many results |
| Age | Number | No | Helps separate similar names |
| Charge | Text | No | Searches charge text or statute wording |
| Arrest Date | Date | No | Useful when the booking date is known |
| Holding Facility | Dropdown | No | Includes Marathon County Jail, Home Monitor, Dane County (Fed), Mendota, Taylor County Jail, and Waupaca County Jail |
What Marathon County Inmate Records Show
A Marathon County inmate record is an expandable public card, not just a name line. It can show the booking agency, holding facility, charge list, bond information, court date, release or expected release information, and a booking image. Public settings hide date of birth, home address, arresting agency, scars and tattoos, traits, property, and arrest notes.
| Field | What it shows |
|---|---|
| Name and age | Public identity fields, with date of birth hidden |
| Mugshot | Images are enabled through P2C ShowImages settings |
| Arrested | Arrest date displayed in the public card |
| Court date | Next scheduled court date when returned |
| Holding facility | Jail, Home Monitor, or other listed holding location |
| Charges | Charge code, description, status, docket number, bond type, bond status, and bond amount |
Marathon County State and Federal Search
County jail custody and state prison custody are often confused. The county roster is for current adult jail and jail-supervised status. The Wisconsin DOC locator is for convicted offenders sentenced to DOC incarceration, supervision, or both. DOC warns that location, status, and release dates can change quickly and that the locator does not include county-jail-only inmates or adjudicated juveniles.
| Custody type | Where to look | Key limit |
|---|---|---|
| Pretrial or county sentence | Marathon County P2C roster | Current roster, not a full historical archive |
| Sentenced Wisconsin prison or supervision | Wisconsin DOC Offender Locator | Does not cover county-jail-only custody |
| Federal sentenced or former inmate | BOP inmate locator | May not show pretrial USMS custody |
| Immigration detention | ICE Online Detainee Locator System | Not a county booking-photo gallery |
The Wisconsin DOC locator is documented at the DOC Offender Locator welcome page, and it is separate from the Marathon County jail roster.
Use DOC after sentencing or supervision begins. Use the county roster when the custody question is about a current jail booking.
Marathon County Detention Facilities
The local facility list is short, but the two facilities serve very different populations. The adult jail is the public inmate roster facility. The juvenile detention facility is secure youth placement and should not be treated as a public adult inmate lookup tool.
- Marathon County Jail - Adult county detention, pretrial custody, sentenced county inmates, Home Monitor supervision, and some accepted holds for other agencies.
- Marathon Juvenile Detention Facility - Secure juvenile detention for children ages 10-17, separate from the adult P2C roster.
Past Marathon County Inmate Records
The live roster can change when someone bonds out, moves to DOC, completes a sentence, transfers, or changes holding status. For older booking records, incident reports, booking photos not shown online, or a date-specific record, the county public-records path is the Marathon County NextRequest form. Include the person's name, approximate booking date, case number if known, and the exact record requested.
The NextRequest form was captured successfully in the manifest from the official Marathon County public-records request endpoint.
That request path matters when the public roster no longer displays the person or when the record needed is broader than the current inmate card.
Marathon County Inmate Population FAQ
How many people are on the Marathon County roster?
The official P2C response returned 251 records on July 3, 2026. Treat that as a roster total, not a certified in-house bed census, because the holding-facility filter includes Home Monitor and other locations.
Where is the adult jail?
The adult Marathon County Jail is inside the Marathon County Courthouse in downtown Wausau. Visitors should confirm the correct entrance, parking, security screening, and visit schedule before traveling.
Are juvenile detainees on the adult roster?
No. The Marathon Juvenile Detention Facility is a secure youth placement facility, and juvenile custody information is legally distinct from adult jail roster information.
What if a Marathon County inmate is not found?
Clear the roster filters, search only by last name, check Wisconsin DOC and VINE, then use BOP or ICE if federal or immigration custody may be involved. For older local records, use NextRequest.
