How to Look Up Ottawa County Jail Population Data
For Ottawa County jail population context, official sources include the county Sheriff's pages, the Michigan Department of Corrections, and federal data from the Bureau of Justice Statistics. The Ottawa County Sheriff jail page covers facility location, services, and inmate lookup. The MDOC site at michigan.gov/corrections covers state custody data. The federal BJS at bjs.ojp.gov publishes annual Jail Inmates reports that show state and national context.
For a real-time snapshot of who is in the Ottawa County Jail right now, the in-custody lookup at app.miottawa.org/InmateLookup is the official tool. The lookup requires a complete last name and a CAPTCHA, which limits its use as a population data tool. The page shows a "Data Last Updated" timestamp, last observed on May 20, 2026 at 04:00 PM, which gives a rough sense of refresh cadence.
Ottawa County Jail Capacity Overview
The Sheriff's pages identify one county jail facility at 12130 Fillmore Street, West Olive. The inspected county pages do not publish a current jail capacity number. Capacity numbers from third-party aggregators are not used here. For a current capacity figure, the county should be contacted directly through the Sheriff Administration office at (616) 738-4000. The table below sums up what the county does publish about the facility.
| Facility | Address | Official Capacity Published? |
|---|---|---|
| Ottawa County Jail | 12130 Fillmore Street, West Olive, MI 49460 | No, not in county pages inspected |
| Sheriff Administration | 12220 Fillmore Street, West Olive, MI 49460 | n/a, administration office |
| Family Justice Center | 12240 Fillmore Street, West Olive, MI 49460 | n/a, court facility |
Average Daily Population
Average daily population, often shortened to ADP, is the standard measure for jail use over time. ADP is the sum of daily inmate counts across a year divided by the number of days. The county's inspected pages do not publish a current ADP number. Annual reports from the Sheriff's Office or county budget documents may include ADP figures in future revisions. Until those are confirmed, this page does not list an ADP estimate.
For state and national benchmarks, the BJS Jail Inmates Series tracks county-level ADP across the U.S. The series is not a real-time tool; it lags by one or more years. State-level ADP data from MDOC may be more current than national series releases. Both are useful as background but should not be confused with current Ottawa County numbers.
Demographic Breakdown
A full demographic breakdown of the Ottawa County jail population by age, sex, race, and citizenship was not located in the inspected official county pages. The current in-custody lookup exposes a gender filter, which suggests gender data is captured at booking. Age and racial breakdowns are not exposed through the public search interface. For a verified demographic profile, a public records request to the Sheriff's Office is the official path.
For broader Ottawa County demographic context, the U.S. Census QuickFacts page publishes county-level population, race, age, and household data. Census data describes the entire county, not just the jail population, but it gives a comparison baseline.
Pretrial vs Sentenced Population
County jails across the country generally house two groups: pretrial detainees awaiting case resolution, and sentenced inmates serving short sentences after conviction. A breakdown of pretrial vs sentenced in the Ottawa County Jail was not located in the inspected county pages. BJS data on county jails shows that the pretrial share of jail population has grown nationally over several decades. State and county-level ratios vary based on bond practice, case processing speed, and program use.
Bond setting in Ottawa County happens at the 58th District Court. A district judge or magistrate sets bond on criminal cases. Standard bond schedules exist for some minor offenses, which lets people post bond quickly. More serious offenses require judicial bond setting after arrest. Pretrial release conditions can include no-contact orders, GPS, drug testing, and other terms.
Misdemeanor vs Felony Population
A misdemeanor vs felony breakdown for the Ottawa County jail population was not located in the inspected county pages. The general structure is that misdemeanors remain in the 58th District Court and may carry shorter jail sentences, while felonies transfer to the 20th Circuit Court and may carry longer terms in either the county jail or the state prison system. Sentenced state prisoners do not stay in the county jail; they move to MDOC custody. The OTIS lookup at mdocweb.state.mi.us/otis2/otis2.aspx is the state tool for that custody type.
Mental Health and Medical Population
The Ottawa County Jail does mental health and medical screening at intake. A current mental-health or medical-population number is not published in the inspected county pages. Probate Court handles mental health proceedings under the Mental Health Code at MCL 330.1748 and lists a separate mental health contact at (616) 738-4128. The Sheriff's jail page describes the corrections mission as detaining inmates securely in the least restrictive setting possible given inmate classification.
For community mental health resources outside the jail, the county's Ottawa County Community Mental Health office at miottawa.org/cmh handles access screening and adult mental health services. Reentry resources include Michigan Department of Health and Human Services for benefits and Michigan Works! for employment support.
National and State Context
The federal Bureau of Justice Statistics publishes Jail Inmates and Prisoners reports each year. These reports give national jail incarceration rates per 100,000 residents, state-level rates, and trend lines over time. Michigan reports come through MDOC and the Michigan Statistical Analysis Center. For Ottawa County, comparing local numbers to state and national context requires verified local data, which is the gap the inspected pages leave open.
Background national jail data is published by the Bureau of Justice Statistics.
BJS reports are useful for state and national context, not for county-level daily counts.
Population Trends Over Time
Tracking trends over time for the Ottawa County jail requires a consistent ADP or month-end count time series. The inspected county pages do not publish that data set. The 2023 20th Judicial Circuit and Probate Courts annual report covers Recovery Court outcomes, including a 75% graduation rate and a 73% lower rearrest likelihood over three years after Recovery Court graduation. That data describes program effects, not jail population totals, but it points to one factor that affects ADP through diversion.
Searching for Ottawa County Inmate Records by Name
This page is about jail population data. For an individual inmate search by name, the right tool is the in-custody inmate lookup, covered in the full Ottawa County inmate records page. For released state prisoners and parolees, see the released inmates page. For federal inmates, see the BOP locator referenced on the released-inmates page. Population data and individual records sit in different systems; mixing them produces confusion.
Where the Ottawa County Jail Data Comes From
Verified Ottawa County jail data comes from the Sheriff's Office. Public-facing summary data may also appear in the county budget, in annual reports, or in board minutes. Statewide data is reported through MDOC. National rollups come from BJS. Third-party incarceration trends sites can be useful for historical context but are not the county's official source. The official county home for these questions is the Ottawa County Sheriff's Office.
Note: Verify any current Ottawa County jail capacity, ADP, or demographic number with the Sheriff's Office before relying on it, since the inspected county pages do not publish those figures.
