Polk County Inmate Population Snapshot
The Polk County inmate population is centered on the Polk County Jail in Dallas. The jail is run by the Polk County Sheriff's Office and holds people arrested by county deputies, Dallas police, Independence police, Monmouth police, Salem police on the Polk side, Grand Ronde police, and other agencies when the jail accepts the custody. It is a local jail, not a state prison. That means the roster is best for people awaiting court, serving local jail time, being held on probation or post-prison sanctions, or waiting on another agency hold.
The jail map is simple, but the custody paths are not. The live roster reviewed in the research showed Polk County cases, Benton and Marion holds, Oregon DOC-related holds, Community Corrections sanctions, parole or post-prison entries, and U.S. Marshals Service holds. A person can be physically housed in Polk County Jail while the court or agency named on the row is outside Polk County. For the Polk County inmate population, that distinction matters because release, case records, and notifications may come from different offices.
Polk County Inmate Population Statistics
The strongest official Polk County inmate population figure found in the research is capacity. The county jail page says the facility has capacity for 195 inmates and was completed in August 1999. The best current public count is the hourly roster. On June 25, 2026, the public JDS roster showed about 120 current entries by table-entry count. That is useful as a point-in-time snapshot, but it is not an official average daily population, annual booking count, or jail census.
Polk County did not publish an official jail ADP dashboard, annual booking table, average length of stay, or demographic jail-population report in the sources reviewed. The right way to present the Polk County inmate population is therefore narrow and sourced: use the official 195-bed capacity, use the dated roster snapshot only as a live-custody proxy, and avoid calculating rates without a dated official ADP.
| Measure | Figure | Source / Year |
|---|---|---|
| Rated jail capacity | 195 inmates | Polk County Jail overview, inspected June 2026 |
| Current roster count | About 120 entries | JDS roster, June 25, 2026 point-in-time review |
| Roster update cycle | Hourly | Inmates In Custody, inspected June 2026 |
| County population context | 90,037 estimated residents | U.S. Census QuickFacts, July 1, 2025 estimate |
The Polk County Jail overview page shows the local jail capacity and history.
That county page is the source for the 195-inmate capacity figure used in the Polk County inmate population table.
Polk County Inmate Population Trends
Multi-year trend data was not located in the official Polk County jail pages. The research checked sheriff and jail pages, the FAQ, the inmate manual, county pages, and search results, but no county-published ADP table or annual booking report was captured. That gap should not be filled with estimates. The live roster is an hourly operational list, while ADP is a separate statistical measure that usually comes from a jail management report or annual county publication.
| Year | Published ADP or Count | Use in Content |
|---|---|---|
| 2022 | Not located | No official Polk County ADP figure found. |
| 2023 | Not located | No official jail-population trend table found. |
| 2024 | Not located | Do not use unrelated Polk County jurisdictions. |
| 2025 | Not located | County resident population is available, but jail ADP is not. |
| 2026 | About 120 roster entries | Point-in-time roster count on June 25, 2026, not ADP. |
State context can help frame the Polk County inmate population without replacing local data. The Prison Policy Initiative's Oregon profile says at least 42,000 people are booked into Oregon local jails each year, but that is not a Polk County booking count. It belongs in statewide context only.
Who Is in Polk County Jail
The Polk County inmate population includes more than new arrests. The roster can show people awaiting court, local sentenced inmates, probation violation sanctions, post-prison supervision sanctions, state parole board matters, and outside-agency holds. Some rows name Polk County Circuit Court, Dallas Municipal Court, or Monmouth Municipal Court. Others may name Benton County, Marion County, the Oregon State Parole Board, DOC, Community Corrections, or the U.S. Marshals Service.
- Pretrial custody: people booked after arrest and held while the case starts or continues.
- Local sentences: people serving court-imposed jail time at the Polk County Jail.
- Supervision sanctions: probation, parole, post-prison, or Community Corrections holds that can be served in jail.
- Other jurisdictions: Benton, Marion, federal, and other holds can appear when Polk houses the person.
- State prison transfers: sentenced prison custody is searched through Oregon Offender Search, not the county roster.
Laws Governing Polk County Jail Data
Oregon law controls what Polk County can release about jail custody and what must be withheld. Oregon public-records law gives a baseline right to inspect nonexempt public records, but the jail may withhold protected data, confidential records, and booking photos when a statute applies. The county roster therefore shows custody facts such as charges, bail, court, housing, and booking date, while leaving out full dates of birth, detailed physical descriptors, and public mugshots.
Key Statutes:
ORS 192.311 to 192.478 governs Oregon public records, including inspection rights, fees, response rules, and exemptions.
ORS 133.870 restricts law-enforcement release of booking photos, which explains Polk County's blank roster photo column.
ORS 169.076 sets statutory standards for local correctional facilities such as written rules, discipline, and access to legal rights.
For a request that the roster does not answer, the best route is the agency with custody of the record. Jail and booking records go to the Sheriff's Office or jail records. Court files go to Polk County Circuit Court or Oregon Judicial Department systems. Oregon prison records go to ODOC.
Search Polk County Inmate Records
The Polk County inmate population search starts at the county's Inmates In Custody gateway, which explains the roster scope and warning notices. After agreeing to the county statements, the official linked roster opens at JDS New Inmate Roster. It is a current table, not a modern search form. Use browser find for the last name, and check the Run Date/Time before relying on a row.
- Open the county Inmates In Custody gateway and read the hourly-update and presumption-of-innocence notices.
- Proceed to the JDS roster and use browser find for the last name, including alternate spellings when needed.
- Read the row as a custody snapshot, not as the full criminal case file.
- Use Jail ID, Book Date, Court, Current Disposition, Total Bail, and Next Court Date to choose the next office.
- If no name appears, call Polk County Jail at 503-623-9254 or check Marion County, OOS, BOP, or ICE as the facts require.
The JDS roster screenshot shows the current-custody table and its blank photo column.
The roster is best read with the county gateway notices nearby because the gateway explains update timing and booking-photo removal.
Polk County Roster Fields
The JDS roster does not ask for search fields. It displays grouped male and female tables with a print button, then row and detail fields. The practical search method is page search within the browser. The row confirms current custody, but it does not publish a full demographic profile or a full case register.
| Roster Item | What It Means | Polk County Note |
|---|---|---|
| Run Date/Time | Timestamp for the current report. | Use it because the roster updates hourly. |
| Jail ID | Local jail identifier. | Five-digit numbers were observed. |
| House | Housing or status code. | Needed for visitation schedule matching. |
| Charges and Court | Booking charge, hold text, and named authority. | May be Polk, municipal, another county, DOC, or USMS. |
| Total Bail | Posted money amount for the row. | $.00 may still mean a hold or sanction. |
| Photo | Photo column. | Blank because photos were removed after HB 3273. |
County Jail vs State Prison
The Polk County inmate population is not one database. The county roster covers the local jail. Oregon Offender Search covers people in ODOC custody or local Community Corrections records. The BOP inmate locator covers federal inmates from 1982 forward. The ICE locator covers people currently in ICE custody or in CBP custody more than 48 hours.
| Custody Type | Where to Search | Best Use |
|---|---|---|
| Polk County jail custody | Polk County Inmates In Custody and JDS roster | Current local jail booking, bail, housing, and court date. |
| Oregon prison or Community Corrections | Oregon Offender Search | Sentenced prison custody, SID search, location, and offense tab. |
| Federal sentenced custody | BOP inmate locator | Federal prison custody and release date notices. |
| Immigration custody | ICE Online Detainee Locator | A-Number or biographical search for ICE detention status. |
Note: No official Polk County Oregon Sheriff mobile app with inmate, warrant, or mugshot lookup was located in the official sources reviewed.
Polk County Detention Facility
The facility map lists one detention facility in Polk County for this project. The Polk County Jail is the county jail for current local custody in Dallas. No state prison, federal prison, ICE detention center, or separate regional jail physically located in Polk County was found in the official source review.
- Polk County Jail holds pretrial detainees, local sentenced people, supervision sanctions, contract or outside-agency holds, and some U.S. Marshals holds when accepted by the jail.
Polk County Jail Details
Several local facts keep the Polk County inmate population from being a simple name lookup. Salem spans county lines, so someone arrested in Salem may be in Marion County Jail or Polk County Jail. The Polk FAQ lists Marion County Jail at 503-581-1183. The jail and court campus is compact in Dallas, and the Polk Circuit Court Criminal Division is located in the jail building across from the courthouse. This makes the jail roster and court record closely linked, but still separate records.
- Detainer or hold
- A request or legal authority from another agency that can keep a person in custody even when a local bail row is shown.
- SID
- Oregon State Identification number used across state criminal-justice records.
- Classification
- The jail's housing and security decision after intake, reflected publicly by House codes.
- Community Corrections
- Local supervision for probation or post-prison matters that may result in jail sanctions.
