Hamilton County Inmate Population Overview
The confirmed local detention facility for Hamilton County is the Hamilton County Jail in Webster City. It is run by the Hamilton County Sheriff's Office and is the local custody point for adult men and women who are booked, held for court, serving short local time, or held for another agency when the jail accepts that custody. The county jail page says the facility can hold Hamilton County prisoners, U.S. Marshals Service prisoners, Federal Bureau of Prisons prisoners, State of Iowa prisoners, and surrounding-county prisoners as needed. That mixed role matters because the Hamilton County inmate population is not the same thing as the statewide prison population.
No separate city jail, county annex, regional jail, work-release center, Iowa DOC prison, BOP prison, or ICE detention facility was confirmed in Hamilton County. People arrested in contracted towns such as Blairsburg, Williams, Jewell, Ellsworth, Randall, Stanhope, Stratford, and Kamrar may still route through the sheriff and county jail. Once a person is sentenced to prison, the record trail shifts to the Iowa Department of Corrections offender search. Federal sentenced custody moves to BOP, and immigration custody uses ICE.
Hamilton County Inmate Population Statistics
The strongest current source for the Hamilton County inmate population is the 2025 PREA audit, supported by the county jail page. The audit reports a small jail profile: a 44-prisoner designed capacity, a current population of 9 in the audit front matter, 12 people on onsite review day one, and a 12-month average daily population of 14. The audit also says the jail was not over capacity at any time in the prior 12 months.
| Measure | Figure | Source / Year |
|---|---|---|
| Designed facility capacity | 44 prisoners | Hamilton County jail page and 2025 PREA audit |
| Average daily population | 14 | 2025 PREA audit, prior 12 months |
| Onsite day-one population | 12 | 2025 PREA audit, August 4, 2025 |
| Housing units | 6 | 2025 PREA audit |
| Over capacity in prior year | No | 2025 PREA audit |
| County population estimate | 14,944 | U.S. Census QuickFacts, 2025 estimate |
The U.S. Census QuickFacts page for Hamilton County gives resident population context, not a jail census. Use it only to understand the county scale around the jail numbers. Jail counts come from jail, inspection, audit, or high-authority jail trend sources.
Hamilton County Inmate Population Trends
Historical trend data show a small, steady Hamilton County inmate population rather than a large urban jail pattern. The Vera Institute county incarceration trends dataset, based on BJS-style county jail measures, rounded the jail population between 10 and 15 average daily people from 2013 through 2019. The 2025 PREA audit average daily population of 14 fits that long-term range, while the official 2025 capacity remains 44.
| Year | Jail Population / ADP | Pretrial Custody | Admissions | Source |
|---|---|---|---|---|
| 2013 | 10 | 10 | 174 | Vera Incarceration Trends dataset |
| 2015 | 14 | 12 | 196 | Vera dataset |
| 2017 | 15 | 12 | 174 | Vera dataset |
| 2019 | 15 | 14 | 191 | Vera dataset |
| 2025 audit lookback | 14 | Not published | Not published | Hamilton County PREA audit |
Small jails can show sharp percentage changes when only a few people move in or out. Hamilton County's current official record is more useful when read as capacity versus average daily population: the jail had room below its 44-prisoner capacity during the 2025 audit period. No official current annual booking total, average length of stay, or detailed offense-category table was located.
Hamilton County Inmate Population Makeup
The 2025 audit describes the Hamilton County inmate population as adults only, with no youthful inmates held at the facility. It reports an age range from 18 through 76 and identifies minimum, medium, and maximum custody levels. The audit does not publish a current race, sex, offense, pretrial, or sentenced breakdown in the same way a public dashboard might. Older Vera demographic fields are useful for context, but they are rounded historical estimates and should not be treated as a live jail roster.
- Local custody: people booked on Hamilton County matters, local sentences, and court commitments.
- Other agency holds: the jail may hold people for surrounding counties, the State of Iowa, USMS, or BOP as needed.
- State prison custody: sentenced prison cases are searched through Iowa DOC, not the county jail count.
- Federal and immigration custody: BOP and ICE locators cover separate public systems after transfer.
For local context, the county resident population is largely White alone in Census QuickFacts, but that is not a current jail demographic table. Do not infer the makeup of the Hamilton County inmate population from resident demographics when the jail source does not publish a matching breakdown.
Hamilton County Jail Capacity
Hamilton County Jail opened in October 2004 and is built as a single small jail. The county jail page and PREA audit both support the 44-prisoner capacity figure. The audit reports six housing units and no over-capacity period in the prior 12 months. Iowa jail standards matter here because capacity is not just a planning number. Iowa Administrative Code 201 chapter 50 says established jail capacity cannot be exceeded except temporarily in an emergency while release or alternate housing is arranged.
The Iowa Department of Corrections recognized Hamilton County Jail in 2025 for outstanding jail operations in the medium-jail category. Local coverage named Jail Administrator Alicia Salic-Leeck and supervisors Jessi-Reding Ratcliff and Samantha Lozano in that recognition. This is useful inspection context, but it is not the same as saying the jail has national accreditation.
Hamilton County Inmate Population Laws
Public access to Hamilton County jail data starts with Iowa law and the office that holds the record. The sheriff holds jail and booking records. The clerk holds court files. Iowa DOC holds sentenced offender records. Each source has its own public access limits, and some facts can be public while a report, juvenile matter, medical detail, victim information, or sealed court record remains restricted.
Key statutes and rules:
Iowa Code chapter 22 gives the public a broad right to examine and copy public records unless a confidentiality rule applies.
Iowa Code section 22.7(9) treats current and prior arrests and criminal history data as public records while protecting criminal-identification files.
Iowa Code chapter 356 governs county jails, sheriff custody of jail prisoners, jail inspection, health, cleanliness, and monthly reports.
Iowa Code chapter 127 can require medical examiner review when a death occurs in jail, prison, or police custody.
Note: A booking record is not proof of guilt; Hamilton County's jail materials repeat the presumption of innocence for people charged with crimes.
Search Hamilton County Inmate Population
The Hamilton County inmate search is unusual because no official public web jail roster was found on the county jail or sheriff pages during research. The official Hamilton County Sheriff IA app on Apple and Hamilton County Sheriff IA app on Google Play advertise an inmate-search feature. The app listings do not expose the search fields, sample records, photo display, update cycle, or release-retention rules from a desktop browser.
The practical search path is therefore app first, jail phone second, records request third, then court, DOC, VINE, BOP, or ICE if custody does not appear local. The Hamilton County Sheriff's Office page gives the sheriff contact block and office hours. The jail page gives the jail phone and family-service details.
- Open the Hamilton County Sheriff IA mobile app and look for the inmate-search feature.
- If the app does not answer the question, call Hamilton County Jail at 515-832-8629 for current custody.
- For copies or older booking facts, contact the Sheriff's Office at 515-832-9500 and frame the request under Iowa Code chapter 22.
- After charges are filed, search Iowa Courts Online for the court case.
- For sentenced state custody, use the Iowa DOC offender search instead of the county jail route.
The Apple App Store listing is an official source for the app name and inmate-search claim.
The app is not an emergency reporting channel; the listing says to call 911 in an emergency.
Hamilton County Roster Search Fields
Because the Hamilton County Sheriff IA app fields could not be inspected from public web listings, the search-field table must stay cautious. The table below describes what is confirmed, what is not, and where to go when an app search does not return a clear current-custody answer.
| Channel | Confirmed Fields | Best Use | Limits |
|---|---|---|---|
| Sheriff IA mobile app | Not inspectable from web | First official digital Hamilton inmate-search route | No visible field list, photo rule, or update cycle in store listings |
| Jail phone | Name, date of birth, arrest date, agency, case number if known | Same-day custody and visitation timing | Some records may require a written request |
| Sheriff records request | Booking date, charge, bond, release, mugshot if releasable | Copies and older booking questions | Iowa Code exceptions may apply |
| Iowa DOC search | Name, offender number, sex, location, offense, county of commitment | Sentenced state offenders | Updated weekly and not for new jail bookings |
Hamilton County Inmate Record Details
A Hamilton County jail record documents custody and booking. It is separate from a court record, which documents formal charges and case progress. Since no public Hamilton web profile was captured, readers should ask whether the app, jail, or records custodian can provide the useful fields below instead of assuming every field appears online.
| Field | What to Ask For |
|---|---|
| Custody status | Whether the person is currently held at Hamilton County Jail or has been released or transferred. |
| Booking date and time | The jail intake date and time if releasable. |
| Charges or allegations | Booking charges may differ from court charges later filed by the prosecutor. |
| Bond or hold status | Ask whether bond is set, no bond applies, or another agency hold blocks release. |
| Court case number | Use this to search Iowa Courts Online after filing. |
| Booking photo | Not confirmed in a public Hamilton web roster; request if releasable under Iowa law. |
Hamilton County Jail vs Prison Search
Hamilton County Jail is the place to check for a person recently arrested in Webster City, unincorporated Hamilton County, or contracted towns served by the sheriff. Iowa DOC is the place to check after a prison sentence or state supervision. Federal and immigration systems are separate. A person can move from one system to another, and the public search trail changes when custody changes.
| System | Who It Covers | Where to Search |
|---|---|---|
| Hamilton County Jail | Local pretrial, short-sentence, and some hold prisoners | Sheriff app, jail phone, sheriff records request |
| Iowa DOC | Sentenced state offenders and state supervision | Iowa DOC offender search |
| Federal BOP | Federal sentenced inmates | BOP inmate locator |
| ICE | Immigration detainees in ICE custody | ICE Online Detainee Locator |
| VINE | Custody and case notifications | Iowa VINELink |
Hamilton County Detention Facilities

Fort Dodge Correctional Facility is nearby in Webster County, but it is not a Hamilton County facility.
- Hamilton County Jail - the county jail for adult local custody, short local sentences, and some state, federal, or surrounding-county holds as needed.
