Jefferson County Inmate Population
The Jefferson County inmate population is centered on the Jefferson County Correctional Facility, the county jail supervised by the Jefferson County Sheriff's Office. The official jail page describes it as the local facility for people criminally charged in Jefferson County, people awaiting trial, and people serving state, county, or municipal time. That mix matters. A person arrested by the Sheriff's Office, Fairfield Police, or another local agency may be in the county jail before any final court result exists.
No official public Jefferson County online roster, daily population dashboard, recent-booking list, or mugshot gallery was located in the county, sheriff, Fairfield, or Iowa court sources reviewed. The Jefferson County inmate population therefore cannot be checked with one live county search form. The reliable local path starts with the jail phone or the Law Center lobby, then moves to Iowa Courts Online for filed criminal cases, Iowa DOC for sentenced prison and supervision records, Iowa VINE for notification, and BOP or ICE when federal custody is possible.
Jefferson County Inmate Population Statistics
The strongest local number is the jail's bed capacity. Jefferson County publishes that the Correctional Facility has 32 beds. The county did not publish a current count, average daily population, annual bookings, average stay, or jail demographic table in the official sources reviewed. That means the Jefferson County inmate population can be described by confirmed capacity and custody type, but no public source supports a precise current headcount.
U.S. Census QuickFacts gives county context for the jail service area. Jefferson County had an estimated population of 15,291 on July 1, 2025, a 2024 estimate of 15,781, and a 2020 Census population of 15,663. The county covers 435.52 square miles, with 36.0 people per square mile in 2020. Those census figures are not jail counts. They help frame why the jail serves a small rural county centered on Fairfield.
The Census QuickFacts page is a useful source for county scale when reading the Jefferson County inmate population alongside local jail capacity.
The image shows the county population source used for local context, while jail-specific custody numbers still have to come from the sheriff or jail.

Jefferson County Jail Capacity Limits
The known capacity for the Jefferson County inmate population is a 32-bed county jail. The official jail page also states that the facility is inspected each year by the Iowa State Jail Inspector and has received a 100 percent score for more than 10 years. That supports a standards and inspection statement, not an overcrowding claim. No source reviewed published a daily population count or year-by-year local average.
Because the Jefferson County inmate population count is not posted online, readers should avoid inferring crowding from the capacity alone. A small jail can be near capacity on one day and well below it on another. The jail phone is the direct route for current custody questions, while broader public-record requests may be needed for historic counts, booking totals, or inspection reports.
| Year | Jefferson County Jail Count / ADP | Public Note |
|---|---|---|
| 2026 | Not published | Capacity remains 32 beds in county jail source |
| 2025 | Not published | No official roster or dashboard located |
| 2024 | Not published | Census county estimate available, but jail ADP absent |
| 2023 | Not published | Official sheriff annual report was located, but ADP was not available here |
| 2020 | Not published | County Census population was 15,663 |
Who Is in Jefferson County Jail
The Jefferson County Correctional Facility holds people criminally charged in Jefferson County, people awaiting trial, and people serving time for state, county, and municipal offenses. That statement covers more than one group. A newly arrested defendant may be there before the first court event. A person with a short local sentence may also be there. A municipal case from Fairfield or another community can still lead to the same county jail.
The Sheriff's Office serves Fairfield, Batavia, Libertyville, Packwood, Vedic City, Pleasant Plain, Lockridge, and unincorporated areas. Fairfield Police also works from the shared Law Center complex. That building detail is important because the City of Fairfield jail page points to the same Jefferson County Jail, not to a separate long-term city jail with its own roster.
- Pretrial custody
- A person is held after arrest while charges, bond, or court dates are still pending.
- Sentenced jail time
- A short local sentence may be served in the county jail instead of a state prison.
- DOC custody
- A sentenced Iowa prison, probation, parole, or work-release record is searched through Iowa DOC.
- Detainer
- A hold from another agency can affect release even when a local bond issue appears resolved.
Laws for Jefferson County Inmate Records
Iowa law separates jail records, court records, and state correctional records. Iowa Code Chapter 22 is the open-records law used for public-record requests to local offices, including sheriff and jail records when no roster is posted. The same chapter allows supervision, fees, and withholding of confidential or exempt material, so it is not a guarantee that every booking item or booking photo will be released.
Iowa Code Chapter 904 governs Iowa DOC records. The DOC locator states offender records are public information under section 904.601(1), with warnings that data is updated weekly and may change quickly. Iowa Code Chapter 804 covers arrest and initial appearance, while Chapter 811 covers bail and pretrial release. Iowa jail standards also require annual inspection and reporting to the sheriff and governing body.
The Iowa Code Chapter 22 source shows the public-records framework behind Jefferson County booking-record and mugshot requests.
That law supports access requests, but the jail and sheriff still apply any record-specific limits or redactions.
Record law distinction: County jail custody, court charges, state prison records, and federal detention records each have their own custodian and search route.
Search Jefferson County Inmates
The Jefferson County inmate population search starts with a fallback chain because no official online roster was found. Call the Jefferson County Jail at (641) 472-3967 for current local custody, visitation time, approval-list questions, mail, funds, or communications. For in-person questions, use the Jefferson County Law Center jail lobby at 1200 W Grimes Avenue in Fairfield. The county and city sources place the jail lobby and parking on the east side of the Law Center.
Have identifying details ready before calling. Jail staff may need a full legal name, date of birth or age, approximate arrest date, arresting agency, and case number if one is known. If staff cannot provide what is needed by phone, a written Iowa Code Chapter 22 request to the sheriff, jail, or county custodian is the next local route for booking, jail, arrest, or incident records.
- Call the jail to ask whether the person is currently in the Jefferson County Correctional Facility.
- Visit the Law Center jail lobby if an in-person access point is needed for local custody or visitation questions.
- Search Iowa Courts Online once charges have been filed and a court case exists.
- Use Iowa DOC Offender Search after sentencing, prison transfer, probation, parole, or work release.
- Check Iowa VINE for custody and case notification when ongoing status alerts are needed.
- Use BOP, USMS, or ICE routes when the case is federal or immigration-related.
Jefferson County Roster Search Limits
Because no Jefferson County online jail roster was located, there are no confirmed local search fields to display. That is the central roster finding. Iowa DOC and BOP have searchable forms, but those systems do not replace the county jail phone for a new Jefferson County arrest.
| Lookup Source | Search Fields or Method | Best Use |
|---|---|---|
| Jefferson County Jail | No public online fields found; call or visit | Current county jail custody |
| Iowa Courts Online | Statewide case search with limited fields | Filed charges, case events, hearings |
| Iowa DOC Offender Search | Name, offender number, sex, location, offense, county of commitment | Prison, probation, parole, work release |
| BOP Inmate Locator | Number search or name search | Federal sentenced custody from 1982 forward |
| ICE ODLS | Federal immigration detainee search | Immigration custody outside the jail roster |
Jefferson County Jail vs DOC
Iowa DOC Offender Search is for sentenced Iowa prison, probation, parole, and work-release records. It is not the Jefferson County jail roster. The sheriff page notes that the sheriff transports inmates to prisons after commitment from the Clerk of District Court, which is the local bridge from jail and court to state custody. For a person in transit, DOC facility assignment may not show until the move is complete.
The Iowa DOC locator is a key search route once a Jefferson County case moves beyond local jail custody.
The state form includes fields that the county jail does not publish online, including location and county of commitment.
| Question | County Jail | Iowa DOC Prison or Supervision |
|---|---|---|
| Who is covered? | New arrests, pretrial detainees, short local sentences | Sentenced prison, probation, parole, work release |
| Where to search? | Jail phone or Law Center lobby | Iowa DOC Offender Search |
| Visits | Law Center list and lobby rules | DOC approval and Ameelio scheduling |
| Jefferson County Jail mail format | DOC central mail-processing address | |
| Money | Jail lobby kiosk | IDOC fiduciary account and vendors |
Federal and Immigration Inmate Search
No BOP prison, ICE detention center, or standalone federal detention center was located in Jefferson County. Jefferson County is in the U.S. Marshals Service Southern District of Iowa. A federal pretrial detainee may be held in a contracted facility outside the county, while a sentenced federal prisoner is searched through the BOP Inmate Locator. Immigration detainees are searched through the ICE Online Detainee Locator System.
The BOP locator uses number and name search paths, and its public result fields differ from county jail and Iowa DOC records.
A BOP result does not prove the person was never in Jefferson County jail; it only shows federal custody or release data in the BOP system.
Jefferson County Detention Facilities
The Jefferson County inmate population touches one primary county jail, one Fairfield city access point in the same Law Center, and two state DOC facilities that matter after sentencing or transfer. The primary jail comes first because it is the current-custody starting point for local arrests.
- Jefferson County Correctional Facility - the 32-bed county jail for local charges, pretrial custody, and short local sentences.
- Fairfield Law Center / Fairfield Police Jail access point - a shared Law Center access point, not a separate city roster.
- Iowa Medical and Classification Center - Iowa DOC reception and classification center for new adult male prison commitments.
- Mount Pleasant Correctional Facility - nearby minimum-security Iowa DOC prison in Henry County.
