Linn County Inmate Population Overview
The Linn County inmate population is centered on the Linn County Correctional Center in Cedar Rapids. Linn County identifies that facility as the only jail in the county, so city arrests, sheriff arrests, local court commitments, municipal cases, state charges waiting for district court, and many short jail sentences all route through one county jail. The facility is run by the Linn County Sheriff's Office and serves as the intake, booking, pretrial detention, sentenced-jail, transport, and courthouse-security hub for the county.
Not every person tied to a Linn County case stays in the county count. A person awaiting trial may appear on the active jail roster, while a person sentenced to state prison moves to the Iowa Department of Corrections system. Federal defendants may be held at the county jail before trial, yet sentenced federal prisoners use Bureau of Prisons records. Immigration detention has its own ICE locator. That split is why the Linn County inmate population must be read by custody stage, not just by name search.
Linn County Inmate Population Statistics
Linn County publishes some jail population facts through official jail pages and the active roster, but it does not publish a current demographic dashboard in the research set. The clearest fixed number is the jail's rated capacity. The current active roster count is useful, but it is a point-in-time search count, not an annual average daily population. Older official snippets give a limited trend line for FY14 and FY16 bookings and average daily population.
| Measure | Figure | Source / Year |
|---|---|---|
| Point-in-time active roster count | 336 people | Official Linn County Inmate Search snippet, June 2026 |
| Rated bed capacity | 401 beds | Official Correctional Center page, inspected June 13, 2026 |
| FY16 average daily population | 354 | Official archived Linn County Correctional Center snippet |
| FY16 bookings | 10,235 | Official archived Linn County Correctional Center snippet |
Linn County Inmate Population Trends
The available Linn County trend data is narrow, so the safest reading is limited. Official archived snippets showed FY14 average daily population at 343 with 11,354 bookings, and FY16 average daily population at 354 with 10,235 bookings. The 2026 active roster snippet showed 336 people, but that is a live custody count from the active list and should not be compared as if it were an annual average. Using the 401-bed capacity and the 336-person roster snapshot, the point-in-time occupancy was about 83.8 percent of capacity.
| Year / Period | Population or Count | Notes |
|---|---|---|
| FY14 | ADP 343; bookings 11,354 | Archived official Linn County jail snippet |
| FY16 | ADP 354; bookings 10,235 | Archived official Linn County jail snippet |
| June 2026 | 336 active roster people | Point-in-time active table count, not ADP |
Linn County Jail Custody Groups
The official jail page says the Linn County Correctional Center holds people awaiting trial and people serving time for state, county, and municipal offenses. It also houses overflow inmates for other jurisdictions and federal prisoners awaiting trial. The research did not locate an official local breakdown by race, sex, charge class, average length of stay, or pretrial share. Those gaps should not be filled with guesses. The confirmed local point is that several legal statuses can share the same building.
- Pretrial detainees: people booked after arrest who are waiting for court, bond, transfer, or release.
- Sentenced jail inmates: people serving state, county, or municipal jail time locally.
- Other-jurisdiction overflow: people held for agencies outside the ordinary Linn County case flow.
- Federal pretrial prisoners: federal defendants housed locally before trial or transfer.
Linn County Jail Capacity Law
Iowa law shapes how the Linn County inmate population is housed and how jail records can be requested. Iowa Code chapter 356 governs jails and municipal holding facilities, including sheriff duties and jail administration. Iowa Administrative Code chapter 201-50 sets jail standards and defines a jail as a place administered by the county sheriff to hold prisoners as lawfully required, with the cited definition tied to custody not exceeding one year.
Key access rules: Iowa Code chapter 22 is the baseline public-records law. Iowa Code section 22.7 lists confidential records and investigative limits. Iowa Code chapter 804 connects arrest, initial appearance, and prisoner disposition.
Search Linn County Inmates
The official Linn County Inmate Search is the first channel for the current Linn County inmate population. The table is labeled Active Inmates and covers people in custody and currently booked into the Linn County Correctional Center. It does not include people who were in custody before but are no longer active inmates. That active-only limit matters for past bookings, mugshot requests, older jail records, and court cases after release.
The roster screenshot below comes from the official active-inmate search page. It shows the public table fields and the table controls used for a Linn County jail roster search.
The official active-inmate search page displays the current roster table with filters and export controls.
The screenshot confirms that the public list is useful for current custody, but it should not be treated as a complete booking-history database.
- Open the Linn County Inmate Search active table.
- Use the global Find box or the Name column filter to narrow the list.
- Filter by Age or Booking Date if the name is common.
- Change page length before using export controls if the visible page is too short.
- If the person is not listed, check court, records-request, DOC, BOP, ICE, or VINE channels.
Linn County Roster Search Fields
The active roster uses a DataTables-style interface. Visible row data is sparse: name, age, and booking date. The official JSON endpoint also returns internal identifiers used to open the detail route, but direct detail-page inspection required CAPTCHA during research. For that reason, the Linn County inmate population pages should not promise public charges, bond, housing, or mugshot fields from the profile view.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Find | Global text search | No | Searches the active table. |
| Name | Column text filter | No | Displays full name in last-name-first format. |
| Age | Column text filter | No | Filters the numeric age shown in the table. |
| Booking Date | Column text filter | No | Visible format is M/D/YYYY. |
| Page length | Dropdown | No | Options include 5, 10, 25, 50, 100, and 1,000 people. |
Past Linn County Inmate Records
Released people fall out of the active inmate search. A past booking may still have a court case, a sheriff record, a mugshot request path, or a state correctional record, but it will not remain in the active table after the person leaves current custody. The Sheriff's Office open-records process is the local fallback for older booking records, reports, and mugshot requests that are not visible on the active list. Payment, if needed, is addressed before the request is processed.
The Sheriff's Office open-records form is the official request path for records not shown on the active roster.
The form is especially important for released-inmate records and mugshot requests, because the active roster is limited to current custody.
Linn County Jail vs DOC
A current Linn County jail inmate and a sentenced Iowa prison inmate are searched in different systems. The county roster is for people currently booked into the Linn County Correctional Center. The Iowa DOC Offender Search is for sentenced state offenders and people under state correctional supervision. Iowa DOC says offender records are public information under Iowa Code section 904.601(1), but it also warns that records update weekly and may change quickly.
| County Jail | Iowa DOC | |
|---|---|---|
| Custody stage | Arrest, pretrial custody, short local sentences | State prison sentence or state supervision |
| Run by | Linn County Sheriff's Office | Iowa Department of Corrections |
| Search tool | Linn County Inmate Search | Iowa DOC Offender Search |
| Linn County facility | Linn County Correctional Center | No state prison is located in Linn County |
Federal ICE and VINE Channels
Some people connected to Linn County do not resolve through the county roster. The BOP Inmate Locator covers federal inmates from 1982 to present, but it is mainly a sentenced-federal custody tool. Federal pretrial defendants may be held at the county jail, and the U.S. Marshals Service Northern District of Iowa has a Cedar Rapids office. For immigration detention, use ICE ODLS or the ICE number listed on Linn County's arraignment resources. For alerts, Iowa VINELink handles custody and criminal-case notification.
- Detainer
- A request or hold from another agency, such as federal or immigration authorities, that may affect release timing.
- Pretrial custody
- Jail custody before a case is resolved by plea, dismissal, trial, sentence, or transfer.
- DOC custody
- State correctional custody after a person moves out of the county jail system.
Linn County Court Records
The jail roster answers the custody question. Court records answer the charge and case-status question. After a jail arrest, the path usually moves from booking to initial appearance, prosecutor charging decision, and docket entries in Iowa Courts Online. For custody details, use Linn County jail inmate records. For booking photo access, the Linn County jail mugshots page tracks what the official roster does and does not show.
Linn County's arraignment page says a person arrested before the early weekday cutoff is scheduled for a morning court time, while weekend and holiday arrests use a separate morning schedule. Future court dates are routed to the Clerk of Court. Bond can be posted at the Clerk of Court during business hours, through a bail bondsman, or as cash-only bond at the jail lobby after the Clerk is closed when county rules allow it.
Linn County Detention Facility
The facility map has one jail entry because Linn County states that the Correctional Center is the only jail in the county. No official municipal jail page was located for Cedar Rapids, Marion, Hiawatha, Robins, or other Linn County cities. No state prison or BOP-operated federal prison is physically located in Linn County.
- Linn County Correctional Center - county jail holding current pretrial detainees, sentenced local jail inmates, overflow inmates, and federal prisoners awaiting trial.
Linn County Jail Communication
Jail population lookup often leads to visitation, phone, mail, and money questions. Linn County uses Telespan/NCIC for phone and video communication. The jail has eight on-site video terminals, while remote video is handled through NCIC. Personal mail is not delivered straight to the Cedar Rapids jail for normal personal-mail processing. It is sent to a Longview, Texas scanning center and delivered electronically to the inmate's housing-unit kiosk.
| Service | Documented Detail |
|---|---|
| Phone calls | $0.20 per minute through Telespan/NCIC, no connection fee |
| Remote video | $0.30 per minute through NCIC |
| On-site video | Eight terminals at the jail, no associated fee |
| NCIC messages | $0.25 each and delivered through the messaging system |
