Ontario, OH carries a PlainCrime C safety grade with violent crime 57% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Ontario, OH shows violent crime at 150.4 per 100,000 residents and property crime at 3,458.6 per 100,000. Violent crime runs 57% below the U.S. average. PlainCrime assigns grade C from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 16.5 per 100,000 in 2020 to 150.4 in 2024 (+812.5%). The highest observed value was 150.4 in 2024 and the lowest 0.0 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Ontario reported 10 violent offences in 2024 against a population of 6,650. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
Comparable rate records
The nearest comparable 2024 records to Ontario's 150.4 violent-crime rate per 100,000 are Upper Sandusky (150.8), Washington Court House (152.7), Fairfield Township (147.9), Reading (152.9). These are same-year agency submissions that pass the same completeness screen, not a claim that the cities have identical conditions. They make the cohort position above checkable against named records instead of a generic state average.
Offense mix
Violent offenses are 4.2% of the 240 Part I offenses reported in Ontario for 2024, against a median of 10.6% across comparable Ohio cities — a gap of 6.4 points. Offense mix is shaped by which agencies report and how incidents are classified as well as by the underlying offenses, so it describes the reported record rather than a settled difference in conditions.
Position in the state cohort
At 150.4 reported violent offenses per 100,000 residents in 2024, Ontario ranks 130 of 340 — above 210 of the 339 other Ohio cities whose 2024 submission passes this site’s completeness test. That is +33.0% against the cohort median of 113.1. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property-offense composition
Larceny-theft is 96.5% of reported property offenses in Ontario, against a cohort median of 83.9%. The remainder is burglary (3) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Ontario's FBI UCR Table 8 municipal row. Per-100,000 rates use the reporting-year population on that row; cities that fail the completeness test stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
Based on 10 reported violent incidents in a population of 6,650. At this volume, one additional or one fewer report can shift the rate and letter grade noticeably; small-city crime counts are inherently more volatile year to year than large-city counts, so treat this grade as a data point, not a precise ranking.
Small-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
Across 11.1 Census sq mi, Ontario logged 20.8 property and 0.9 violent offenses per square mile in 2024.
Ontario's 2024 book concentrates in larceny-theft (93% of 240 offenses; mix index 8,574).
Violent offenses are only 4% of the municipal total - a property-led book.
