Dauphin County Inmate Population
The Dauphin County inmate population is centered on Dauphin County Prison, the county jail at 501 Mall Road in Harrisburg. County research identifies three local custody or custody-adjacent facilities: the main prison, the Dauphin County Judicial Center / Central Booking Facility, and the Dauphin County Work Release Center. They do not all hold the same type of person. The prison is the main site for pretrial detainees, sentenced county inmates, probation and parole violators, and people held for other authorities. Central Booking handles arrest processing and initial court movement. Work Release is a community-corrections setting for court-approved residents.
The count rises and falls through daily arrest activity, bail decisions, court orders, new sentences, transfers to the Pennsylvania Department of Corrections, and holds for federal, state, police, or immigration authorities. Dauphin County's 2024 year-end report says monthly population figures are generated daily at 12:02 a.m. and include the prison population plus male and female Work Release transfers. That source makes the Dauphin County inmate population more than a simple jail head count.
The county prison page is the official source hub for local custody links. The county's inmate lookup, visitation page, family and friends page, commissary instructions, Prison Board materials, annual reports, and point-in-time studies all branch from that official prison section.
Dauphin County Inmate Population Statistics
The strongest local figures come from the 2024 Dauphin County Prison year-end report, the 2025 county medication-assisted-treatment RFP, and the February 2025 Criminal Justice Advisory Board point-in-time report. Read together, those sources show a system with a main prison capacity near 805, a Work Release capacity near 129, and a total named-facility capacity near 934.
| Measure | Figure | Source / Year |
|---|---|---|
| Main prison capacity | Approx. 805 | Dauphin County MAT RFP, 2025 |
| Work Release capacity | Approx. 129 | Dauphin County MAT RFP, 2025 |
| Average in-house population | 829 | Dauphin County Prison year-end report, 2024 |
| Average total population | 964 | Dauphin County Prison year-end report, 2024 |
| Admissions | 8,128 | Dauphin County Prison year-end report, 2024 |
| Releases | 3,977 | Dauphin County Prison year-end report, 2024 |
Dauphin County Jail Population Trends
The 2024 report shows a decline from the prior year. Average total population fell from 1,067 in 2023 to 964 in 2024, and average in-house population fell from 940 to 829. January was the only 2024 month above 999 average total population. Work Release moved differently by gender, with average male Work Release population rising from 103 to 116 while average female Work Release population fell from 24 to 18.
| Year / Period | Figure | Notes |
|---|---|---|
| 2023 | 1,067 average total population | Prison plus Work Release transfers. |
| 2023 | 940 average in-house population | Main in-house jail count. |
| 2024 | 964 average total population | Down from 2023. |
| 2024 | 829 average in-house population | Down from 2023. |
| February 2025 | 939 point-in-time basis | Used for race, gender, and charge-type categories. |
Dauphin County Inmate Makeup
The February 2025 point-in-time report gives a local snapshot of who made up the Dauphin County inmate population. Its 939-person basis included race and gender categories, warrant and hold categories, and charge-type groups. Black males were the largest reported group at 486 people, followed by White males at 234 and Hispanic males at 117. Among women, the same report listed 41 White females, 39 Black females, 7 Hispanic females, and 2 Asian females.
- Violent charge category: 243 people, or 19% of the point-in-time charge-type categories.
- Bench warrant category: 146 people, or 12%, showing how warrant status affects jail counts.
- Federal category: 109 people, or 9%, even though no BOP facility sits in Dauphin County.
- ICE category: 31 people, or 2%, which matches the roster's ICE-number field and detainer context.
- State category: 55 people, or 4%, showing the overlap between county jail custody and state authority.
Dauphin County Jail Capacity
Capacity matters because the Dauphin County inmate population can sit near or above the local system's practical bed count depending on admissions, releases, and transfers. The 2025 MAT RFP states that the main prison can accommodate about 805 inmates and Work Release about 129. The 2024 average total population of 964 was above that combined named-facility capacity, while the average in-house population of 829 was just above the main-prison capacity estimate. The research did not locate a DOJ consent decree, but the 2024 annual report does acknowledge staffing pressure, contraband control, PREA and internal-affairs work, policy revisions, and historical criticism.
Capacity is also tied to case timing. A person can enter at Central Booking, wait for arraignment, move to the prison after commitment, post bail, receive a court release order, transfer to another institution, or later enter state DOC custody. Those pathways mean the Dauphin County inmate population is a moving operational count, not a single public roster page.
Dauphin County Jail Record Laws
Pennsylvania law gives the public a route to many government records, but jail, court, criminal-history, and mugshot records do not all follow the same rule. Dauphin County's open-records page names Vince Paese as the county open-records officer, while criminal-record and law-enforcement requests are routed to the District Attorney process when they involve investigative or criminal-history material.
Key Statutes:
Pennsylvania Right-to-Know Law, 65 P.S. ยงยง 67.101 et seq. gives access to public records unless an exemption or another law applies.
Open-records officer rules require agencies to designate an official route for public requests.
Pennsylvania CHRIA guidance treats criminal-history information, including mug shots in that guidance, differently from ordinary administrative records.
61 Pa.C.S. Chapter 17 covers county correctional institution oversight and prison-board governance.
Dauphin County and PA DOC
The county jail roster is not the same as the state prison locator. The Pennsylvania Department of Corrections service page says the state locator is for state-sentenced inmates and parolees, is updated daily, and excludes county-facility inmates. No PA DOC prison is physically inside Dauphin County. Men entering DOC are commonly processed through SCI Camp Hill in nearby Cumberland County, while women enter through SCI Muncy in Lycoming County.
A Dauphin County defendant may therefore appear on the county roster during pretrial custody, disappear after a transfer, and later appear in the PA DOC locator. Use the county system for people in Dauphin County Prison, Central Booking timing issues, and Work Release questions. Use PA DOC for a state sentence or parole supervision.
Search Dauphin County Inmates
The official online lookup path starts at the county's Inmate Lookup redirect notice and sends users to the external IML v. 3.0 roster. The county warns that the roster is outside the county website, but the research identifies it as the documented public county search interface. It is free, public, and does not require a login.
The IML tool supports a name search and an identifier search. A broad last-name search may return several rows. The result list can show the inmate name, booking number, permanent ID, date of birth, and release date when one exists. Click the result row to open the profile.
- Open the Dauphin County IML roster from the county redirect or direct URL.
- Use the name search with last name, first name, and optional date of birth.
- Check "Include released inmates" if the person may have left custody.
- Use identifier search for a booking number, permanent number, state ID, county ID, FBI number, or ICE number.
- If no county result appears after sentencing, check the PA DOC locator instead.
Dauphin County Roster Fields
The IML search screen is old-style but useful because it accepts both names and multiple identifiers. The county roster covers county jail custody, not state prison custody, and a very new arrestee may still be at Central Booking before a full IML commitment record appears.
The official IML search form is shown in the county roster screenshot captured from the Dauphin inmate lookup search page.
The search form separates name lookup from identifier lookup, which helps when a booking number, FBI number, or ICE number is already known.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| First Name | Text | Unspecified | Useful with last name to narrow common names. |
| Last Name | Text | Practical name-search field | Most useful starting field for a name search. |
| Date of Birth | Date mask | Optional | Uses mm/dd/yyyy format. |
| Include released inmates | Checkbox | Optional | Expands the search to people with release dates. |
| Select Identifier | Dropdown | Optional path | Booking Number, Permanent Number, State ID, County ID, FBI Number, or ICE Number. |
| Value | Text | Required for identifier search | Enter the matching number or ID. |
Dauphin Released Inmate Records
IML includes an "Include released inmates" checkbox, so a past Dauphin County inmate search should start there. The research did not locate a separate county archive with a fixed public retention period for every released record. If the person is not visible online, use the prison phone line for current timing, Central Booking for a fresh arrest, and the Dauphin County Open Records process for administrative records that are not already public.
Criminal-record, police-report, and investigative material may not be released by the prison under ordinary open-records handling. Dauphin County's open-records page says criminal records or related inquiries should be directed to the Office of the District Attorney. Formal charges after an arrest belong in UJS docket records, not just the jail profile.
Dauphin County Inmate Record Details
A Dauphin County IML profile can show identity fields, demographics, housing and location fields, commitment date, projected release date, bond data, charges, detainers, aliases, and hearing information. The inspected public profile did not display a mugshot, even though image-related functions existed in the page code. Treat the roster as a custody and booking information tool first.
| Field | What It Shows |
|---|---|
| Booking # | Dauphin booking number such as a DC-number, useful for exact lookup. |
| Permanent ID # | Internal permanent number that can also be searched from the identifier dropdown. |
| Current location | Broad facility or location value, such as MAIN. |
| Housing block, cell, bed | Granular housing fields that may be blank in public view. |
| Bond | Bond type, amount, status, percent, set-by field, set date, and total when public. |
| Charges | Case number, offense date, code, description, grade, and degree when present. |
| Detainers | Holds from another authority or a no-detainer message. |
Dauphin County Jail vs State Prison
People often search the wrong system after a court case changes status. Dauphin County Prison is the county jail for arrest, pretrial custody, county sentences, holds, and transfer waits. PA DOC is the state system for sentenced state inmates and parolees. Federal BOP and ICE are separate systems again.
| County Jail | State Prison / DOC | |
|---|---|---|
| Who is held | Pretrial detainees, county sentences, violators, holds, and transfer waits. | State-sentenced inmates and parolees under PA DOC supervision. |
| Run by | Dauphin County Prison / county corrections system. | Pennsylvania Department of Corrections. |
| Where to look | Dauphin IML roster and prison phone line. | PA DOC Inmate and Parolee Locator. |
| Mail and visits | Dauphin County Prison rules and ViaPath mail scanning. | DOC visitation, Smart Communications mail, and DOC facility rules. |
Dauphin State Federal ICE Search
Use the PA DOC locator for state sentences and parolees. Use the BOP inmate locator for federal custody from 1982 forward. Use the ICE Online Detainee Locator System for immigration detainees by A-number and country of birth or by biographical search. VINELink at VINELink is useful for custody-status notifications when Pennsylvania records are available.
The February 2025 point-in-time report counted Federal and ICE categories inside the Dauphin County prison population snapshot, so these fallback tools are not optional edge cases. A county profile can show FBI or ICE number fields, but a federal or immigration move can take the person outside the Dauphin roster path.
Dauphin County Detention Facilities
The Dauphin County inmate population is split by function. The main prison holds the core jail population, the Judicial Center handles booking and Night Court, and Work Release serves a narrower court-approved population.
- Dauphin County Prison - primary county jail for pretrial detainees, sentenced county inmates, violators, and people awaiting transfer.
- Dauphin County Judicial Center / Central Booking Facility - 24/7 arrest processing, fingerprinting, Night Court, video arraignment, and diversion screening.
- Dauphin County Work Release Center - community-corrections setting for court-approved residents who may keep work, treatment, and program ties.
Dauphin County Inmate Population FAQ
How big is the Dauphin County inmate population?
The 2024 year-end report lists an average total population of 964 and an average in-house population of 829. A February 2025 point-in-time report used a 939-person basis for demographic and charge-type data.
How do I search the Dauphin County inmate population?
Start with the Dauphin IML roster. Search by name or by identifier, then include released inmates if needed. Use Central Booking by phone for a very new arrest and PA DOC after a state sentence.
Does the Dauphin roster include mugshots?
The inspected public IML profile did not display a mugshot. Booking-photo access in Pennsylvania is tied to CHRIA and law-enforcement records rules, so do not treat IML as a public mugshot gallery.
