The Sioux County Inmate Population
The local Sioux County inmate population is centered at Sioux County Jail, the Public Safety Center jail in Orange City operated by the Sioux County Sheriff's Office. The jail is the county's primary detention site, and official research found no Iowa Department of Corrections prison or Bureau of Prisons institution physically located in Sioux County. ICE does list Sioux County Jail as a detention facility, so immigration detention in the county uses the same local building rather than a separate ICE jail.
The count can include several groups at once. The facility map identifies pre-trial detainees, sentenced county inmates, work release, federal holds, ICE or federal immigration detainees, and other agency holds. That mix matters when reading the roster. A person listed as a federal hold or hold for another agency may be physically housed in the Sioux County Jail while release authority belongs to a court, ICE, BOP, or another agency. The jail roster confirms local custody, but it does not replace a court docket, a DOC prison record, a BOP record, or an ICE custody lookup.
Sioux County Inmate Population Statistics
Sioux County publishes a jail population report and has facility figures in the 2024 PREA final audit. The current official capacity used for this build is 67 beds, because the jail page and PREA audit both use that figure. An older sheriff about-page reference to 70 inmates exists, but the audited number is the safer current capacity. The population report dated June 12, 2026 at 21:00 listed 46 people in custody, with 42 males, 4 females, and 9 federal holds.

Sioux County Inmate Population Trends
The official sources do not provide a full three-year or five-year average daily population series for Sioux County Jail. They do provide a useful point-in-time and audit trend: the 2024 PREA audit reported a 12-month average daily population of 32, a current population of 36 on the audit form, and no point over capacity during the prior 12 months. The June 12, 2026 jail population report was higher, at 46 people, but still below the 67-bed capacity.
| Year / Date | Population / ADP | Notes |
|---|---|---|
| 2024 PREA audit | 32 ADP | Average daily population for the prior 12 months |
| 2024 PREA audit day | 36 | Current population listed in facility information |
| 06/12/2026 21:00 | 46 | Population report listed 42 males, 4 females, and 9 federal holds |
State and national context should stay separate from the Sioux County inmate population. Research notes cite national jail admissions and Iowa-wide jail growth from outside sources, but those are not Sioux County counts. They are best used as background only. The strongest local trend is that the Sioux County Jail was under listed capacity in both the 2024 audit and the June 2026 population report.
Who Is Counted in Sioux County Jail
The June 2026 population report gives the clearest demographic count: 42 males and 4 females out of 46 people in custody, with 9 federal holds. The PREA audit also confirms the jail holds adult males and adult females, with an age range of 18 to 60 on the audit materials and no youthful inmates. Those facts are narrower than a full demographic study. They should not be read as race, charge-level, or length-of-stay data, because the official local sources did not publish those breakdowns.
- Pre-trial inmate
- A person held after arrest while a case, bond decision, or first appearance is still pending.
- Sentenced county inmate
- A person serving a local sentence in Sioux County Jail rather than a state prison term.
- Federal hold
- A person held locally while a federal agency or immigration process may affect release.
- Work release
- A local custody status that may let an approved inmate leave for work under jail rules and fees.
Sioux County Jail Capacity
Sioux County Jail is described as a 67-bed facility with six housing pods. Each pod has cells, restroom and shower facilities, and a dayroom. The jail also has indoor recreation, booking and processing space, a medical room, and a central control room where staff monitor activity. Classification uses gender, custody status, offense level, work release, federal holds, and special housing needs.
The capacity record does not show current overcrowding. The 2024 PREA audit answered "No" to whether the facility was over capacity at any point in the prior 12 months. The June 2026 jail population report listed 46 people against 67 beds. A 2026 official sheriff warning mentioned scammers falsely telling families that inmates could be released early because of overcrowding. That release was a scam warning, not an official finding that the jail was over capacity.
Laws for Sioux County Jail Data
Iowa law explains why some jail and inmate data can be read by the public while other details are withheld. The starting point is Iowa's open-records law, but jail records can still be redacted for active investigations, juvenile data, protected victim or witness information, health information, criminal intelligence, and other confidential material. Sioux County's public-records page applies those limits to local jail record checks and incident reports.
Key Statutes:
Iowa Code chapter 22 governs examination and copying of public records, subject to confidentiality exemptions and reasonable fees.
Iowa Code section 356.49 requires county sheriffs to file monthly jail reports with total numbers of men, women, and juveniles held.
Iowa Code section 356.36 requires minimum standards for Iowa jails and related holding facilities.
Iowa Code section 904.601 makes DOC offender records public information for the state corrections locator.
Search the Sioux County Inmate Population
The main local lookup is the Sioux County current inmate roster PDF. It is linked from the sheriff homepage and jail information page. It is not an interactive search portal. The roster inspected on June 12, 2026 carried an "Updated on" timestamp and listed current inmates by date booked, name, reason booked, and charge lines. Use PDF or browser Find for a last name, first name, or charge term.
- Open the sheriff roster PDF or choose the current roster link from the sheriff website.
- Check the timestamp at the top before relying on the status.
- Use PDF Find for the last name first, because names appear in LAST,FIRST style.
- Read the date booked, reason booked, and charge rows below the name.
- Call the jail at (712) 737-3131 when release, bond, transfer, or hold status is urgent.
When a person is not listed, the next channel depends on the problem. Recent arrests or released entries may appear in the sheriff arrest press log or the sheriff app. Older local jail record checks go through the sheriff public-record request process. Sentenced state prisoners move to the Iowa DOC Offender Search. BOP and ICE systems cover federal prison custody and immigration detention.
Current Sioux County Inmate Lookup
The roster is lean by design. It confirms that a person is listed in current county custody, but it does not show booking numbers, mugshots, date of birth, age, race, sex, bond, housing pod, court date, or a clickable profile. For a fast search, treat it like a report rather than a database. If the roster says "FEDERAL HOLD" or "HOLD/OTH AGENCY," verify the release authority before assuming the jail can release the person on a county bond.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Search within PDF / browser Find | Text | Optional | No official search form; use Find for name, reason booked, or charge text. |
| Date Booked In | Displayed column | N/A | Date format appears as MM/DD/YYYY. |
| Inmate Name | Displayed column | N/A | Uppercase LAST,FIRST MIDDLE style. |
| Reason Booked Desc | Displayed column | N/A | Examples include federal hold, warrant, court order, serve sentence, and hold for other agency. |
| Charge sequence | Displayed rows | N/A | Charges are numbered and may be abbreviated. |
| Refresh notice | Timestamp | N/A | The PDF carries an update timestamp, with no broader refresh-frequency promise. |
Sioux County Inmate Record Fields
The current roster has fewer fields than the sheriff arrest log and active warrant list. That difference is important. The current roster is best for "is this person in jail right now?" The arrest log is better for bond amount, bond type, release date, and release reason. The warrant list has warrant numbers and physical descriptors. A public-record request is the fallback when the online reports do not answer the custody question.
| Field | What It Shows |
|---|---|
| Updated on timestamp | When the roster PDF was generated. |
| Date Booked In | The calendar date the person entered jail custody. |
| Inmate Name | Uppercase name, usually last name first. |
| Reason Booked Desc | Custody reason such as warrant, serve sentence, federal hold, or court order. |
| Charge lines | Numbered charge descriptions, often abbreviated. |
| Not shown | Mugshot, DOB, booking number, bond, court date, housing pod, and arresting agency. |
Sioux County State and Federal Search
Sentenced state prisoners from Sioux County are searched through the Iowa DOC Offender Search, not through the county jail roster. The DOC search accepts first, middle, and last name, offender number, sex, location, offense, county of commitment, and a name-search type. County of commitment can be set to Sioux. DOC warns that records are public under Iowa Code section 904.601, but they are updated weekly and may change quickly.
The Iowa DOC Offender Search page is a matching visual source for the state-prison lookup channel.
The DOC form should be used after a prison sentence or transfer, while Sioux County Jail remains the source for current local custody.
| System | Best For | Limit |
|---|---|---|
| Sioux County roster | Current county jail custody | No mugshots, bond, court date, or profile page |
| Iowa DOC Offender Search | Sentenced state prisoners and supervision records | Not a live county jail roster |
| BOP Inmate Locator | Federal inmates in BOP custody from 1982 to present | May not show pretrial federal detainees housed locally |
| ICE ODLS | Immigration detainees | Requires ICE locator search and may differ from county shorthand |
| Iowa VINELink | Custody or case notification | Notification tool, not a full jail record |
Sioux County App and Records
The Sioux County Sheriff app is an additional access channel. The official app page and Google Play listing describe contacts, press releases, arrests, inmate search, sheriff sales, most wanted, alerts, and more. The sheriff page says the app includes recent arrests for the last 30 days, current inmates, inmate lookup and protection-order notifications, and most wanted with mugshots. Those app features are useful because the website's current roster is a sparse PDF.
The successful screenshot from Google Play matches the sheriff app channel documented in the research.
Use the app as a helpful route to alerts and lookup tools, but call the jail or use the public-record request process for official record needs.
For records not visible online, Sioux County Sheriff's public-records process accepts requests in person, by mail, by phone with payment sent separately, or by email to records@siouxcounty.org with payment mailed separately. A local jail public-information record check requires the subject's full name and date of birth plus a valid government-issued photo ID from the requester. The response gives only date of arrest, arresting agency, and charges. It does not provide disposition and does not cover juvenile records, traffic records, or records from other agencies.
Sioux County Detention Facilities
The facility map resolves one Sioux County detention facility for the site: Sioux County Jail. State prisons should not be added as local Sioux County facilities, because DOC lists Iowa prison locations elsewhere in the state. ICE custody is still relevant because ICE lists Sioux County Jail as a detention facility and the county population report counted federal holds.
- Sioux County Jail - county jail and ICE-listed detention facility operated by the Sioux County Sheriff's Office for pre-trial custody, sentenced county inmates, work release, federal holds, immigration detainees, and other agency holds.
