Niagara County Inmate Population Overview
The Niagara County inmate population is centered on the Niagara County Correctional Facility in Lockport. The sheriff-operated jail is the county's main adult custody site for people arrested by sheriff's deputies, city police, town police, village police, state police, and some federal authorities. The facility is not just a pretrial lockup. New York DCJS and State Commission of Correction reports count sentenced local inmates, federal people, technical parole violators, state-ready inmates, civil categories, and other unsentenced people in the Niagara County Jail population.
No official source reviewed listed a New York DOCCS prison, Federal Bureau of Prisons institution, ICE-owned detention center, or separate adult regional jail physically in Niagara County. The Niagara Falls Police Holding Center is a short-term municipal police lockup, but people booked into ongoing county custody are searched through the sheriff's roster. State-sentenced prisoners move to the New York DOCCS locator. Federal sentenced prisoners move to BOP. Immigration detainee searches use ICE ODLS.
Niagara County Inmate Population Statistics
The strongest current data comes from the NY DCJS/SCOC monthly jail population report prepared June 1, 2026, the annual jail population report prepared February 2, 2026, and March 2025 State Commission of Correction variance materials. Those sources show a jail operating below maximum capacity in May 2026, after several mid-2025 months that were above or near the current maximum facility capacity.
| Measure | Figure | Source / Date |
|---|---|---|
| May 2026 average daily census | 397 | NY DCJS/SCOC monthly jail report, prepared 6/1/2026 |
| May 2026 in-house ADP | 395 | NY DCJS/SCOC monthly jail report |
| Current maximum facility capacity | 447 | SCOC March 2025 variance materials |
| 2025 annual average daily census | 436 | NY DCJS/SCOC annual jail report, prepared 2/2/2026 |
| 2025 bookings | 2,904 | Niagara County Sheriff's Office 2025 annual report |
Niagara County Inmate Population Trends
The Niagara County inmate population fell sharply in 2020, then climbed again through 2025. The annual report row shows a 2020 low point followed by a steady rebound, with 2025 higher than 2016. Monthly data then shows a high stretch in mid-2025 and a decline into spring 2026. That matters for custody searches because a crowded period can create more state-ready transfers, federal contract holds, and movement between jail categories.
| Year | Annual ADP / Census | Notes |
|---|---|---|
| 2016 | 416 | Annual jail population baseline. |
| 2020 | 265 | COVID-era and bail-reform decline noted in state reporting context. |
| 2021 | 348 | Population rebounded from the 2020 low. |
| 2024 | 413 | Near the 2016 level. |
| 2025 | 436 | State report says this was 5 percent above 2016 and 6 percent above 2024. |
Bookings followed a similar upward path through 2024 before easing in 2025. Sheriff annual reports list 1,778 bookings in 2020, 2,115 in 2021, 2,360 in 2022, 2,622 in 2023, 3,094 in 2024, and 2,904 in 2025. Bookings are not the same as daily population because one person may stay a few hours while another stays for months.
Who Is Held in Niagara County Jail
The May 2026 monthly report breaks the in-house Niagara County inmate population into useful custody categories. Other unsentenced people were the largest category, with 186 of 395 in-house. Sentenced local inmates averaged 105. Federal custody was also large at 97, which matches the roster research that found a "United States Marshal Remand" example in the official data. Technical parole violators averaged 3, and state-ready inmates averaged 4 after higher late-2025 state-ready numbers.
- Other unsentenced: people held before final case disposition, often after arraignment or while a case is pending.
- Sentenced local: people serving local jail terms rather than a DOCCS prison sentence.
- Federal: people held for federal authorities, including USMS remand categories.
- State-ready: people waiting for transfer to state prison after the local jail stage.
Public roster fields do not show each category in the same way state reports do. A roster record may show a statute code, charge description, bail value, or hold reason. The state report is better for population counts. The sheriff roster is better for a current person-by-person lookup.
Niagara County Jail Capacity
The current official maximum facility capacity cited in March 2025 State Commission of Correction variance materials is 447. Older sheriff history says the 1996 expansion increased the jail to 449 beds, which is useful history but not the current capacity number to use for a capacity comparison. Several 2025 monthly census values were above or close to the 447 MFC. May 2025 was 464, June 2025 was 471, and July 2025 was 461. By May 2026, the average census had fallen to 397.
The same March 2025 materials discussed Building #2 Pods 1 through 4 and double-celling variance conditions. The research reports four 56-cell direct-supervision pods arranged around a unit control center. The variance material described 14 cells in each pod designed with two bunks and conditions tied to active supervision, staffing, record keeping, and not using the variance to board people for revenue.
Laws for Niagara County Jail Data
New York law separates public access, court records, jail standards, and custody orders. FOIL is the broad access path for agency records, but it has exemptions. Court records use clerk and court rules. Jail population and conditions oversight runs through the State Commission of Correction, not the county roster alone.
Key Statutes:
Public Officers Law § 87 requires agencies to make records available under FOIL rules, subject to exemptions.
Public Officers Law § 89 sets FOIL timing and procedure and addresses arrest or booking photos in the privacy context.
Correction Law § 45 gives the State Commission of Correction inspection, standards, and reporting authority.
Correction Law § 47 governs death-in-custody reporting and Medical Review Board review.
Niagara County and State Prison
No DOCCS prison was located in Niagara County's official facility map. That does not mean state prison is irrelevant. A Niagara County defendant sentenced to state custody leaves the county roster and becomes a New York DOCCS Incarcerated Lookup search subject after reception and transfer. The state-ready jail category captures people waiting for that move. DOCCS also lists a Niagara Frontier Area Office in Niagara Falls for community supervision, but that is a parole office, not a prison or jail.
Search the Niagara County Inmate Population
The official starting point for current local custody is the sheriff's Incarcerated Individual Search. The page uses a Type to Search field over current roster cards. The visible page shows names and booking-photo images, with pagination. The official OCV feed and public JSON behind the roster expose more detail, including booking numbers, demographics, booking dates, charges, statute codes, bail fields, and image URLs.
- Open the sheriff's Incarcerated Individual Search page.
- Use Type to Search for a name or likely text string.
- Move through pagination because the roster is longer than one page.
- Open the person's card or detail route when available.
- If no record appears, check DOCCS, BOP, ICE ODLS, VINELink, the jail phone line, or a FOIL request path.
The sheriff's mobile app is also part of the access chain. The Apple and Google listings say the Niagara County Sheriff NY app can show inmates booked into the correctional facility and can support bail posting. App alerts and road-closure features are separate from custody records and should not be used for emergencies.
Niagara County Roster Search Fields
The Niagara County inmate population roster is simpler than many multi-field jail portals. The public page does not show separate first-name, last-name, date-of-birth, facility, or booking-number boxes. It uses an on-page text filter and pagination over roster cards. That design makes exact spelling helpful, but it also means partial names may help when a person is listed under a middle name or alternate spelling.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Type to Search | Text filter | Optional | Filters current roster cards on the sheriff page. |
| Pagination controls | Buttons | Optional | Inspection showed many pages, so page one is not complete. |
| Inmate name link/card | Link | Not applicable | Each card can point to an individual detail route. |
| Mugshot image | Image | Not applicable | Cards use sheriff/OCV image URLs when a booking photo is present. |
The official sheriff roster screenshot at niagarasheriff.com/incarcerated shows the Type to Search field, roster cards, booking photos, and pagination.
The screenshot matches the research finding that the public page is a current-roster card interface rather than a full archive search.
What Niagara County Inmate Records Show
A Niagara County inmate record should be read as a custody and booking record, not as proof of conviction. The official public data feed may show more than the visible roster card. It can include a booking number, age, sex, height, weight, race, eye color, hair color, booking ORI, booking date, charges, statute code, charge description, bail field, and an image URL. It does not expose a housing pod, court date, judge, total bond, projected release date, date of birth, or residential address in the inspected public JSON.
| Field | What It Shows |
|---|---|
| BookingNumber | Local year-sequential booking identifier used by the jail data. |
| BookingDate | Date and time tied to intake or the charge record. |
| Charges | Array of charge or hold objects, each with code, description, and bail field. |
| Bail | Per-charge bail value, often N/A when no bail is listed. |
| Image | Booking-photo URL hosted through the sheriff/OCV system. |
Past Niagara County Inmate Records
The sheriff roster is a current custody tool. The research did not locate a public released-inmate archive, refresh interval, or retention window after release. If a person is no longer listed, the next path depends on what happened. Recent release may mean the person is no longer in the live roster. Sentencing may mean transfer to DOCCS. A federal sentence may move the search to BOP. Immigration custody may require ICE ODLS. Older booking records or missing mugshots require a sheriff or county FOIL request, subject to New York exemptions, sealed records, privacy limits, and law-enforcement concerns.
Niagara County Jail vs State Prison
Many failed inmate searches come from using the wrong system. The Niagara County jail roster covers local custody at the sheriff's correctional facility. DOCCS covers sentenced state prisoners. BOP covers federal sentenced prisoners. ICE ODLS covers immigration detainees. A federal remand may still appear in the Niagara roster while housed locally, but that is not the same as a BOP sentenced-prison record.
| County Jail | State Prison | Federal / ICE | |
|---|---|---|---|
| Who is held | Pretrial, local sentenced, federal remands, holds | State-sentenced prisoners | Federal sentenced or immigration detainees |
| Run by | Niagara County Sheriff's Office | New York DOCCS | BOP, USMS, or ICE |
| Lookup | Sheriff Incarcerated Individual Search | DOCCS Incarcerated Lookup | BOP locator or ICE ODLS |
Niagara County Detention Facilities
The facility map has one long-term adult county custody facility and one municipal police holding center. The county jail is the roster source. The Niagara Falls lockup is a short-term police holding site before court, release, or transfer, and no separate public city roster was located.
- Niagara County Correctional Facility - sheriff-operated county jail for current local custody, local sentences, federal remands, state-ready inmates, and other reported jail categories.
- Niagara Falls Police Holding Center - municipal police holding center for short-term custody before court or transfer to the county jail.
Niagara County Jail Service Paths
