According to the FBI Uniform Crime Reporting (UCR) Program for 2024, McHenry, IL shows violent crime at 94.5 per 100,000 residents and property crime at 619.7 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
McHenry reported 27 violent offences in 2024 against a population of 28,563. 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 McHenry's 94.5 violent-crime rate per 100,000 are Washington (95.2), Woodstock (93.3), Park Ridge (96.3), Brookfield (92.7). 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 125.6 per 100,000 in 2020 to 94.5 in 2024 (-24.8%). The highest observed value was 125.6 in 2020 and the lowest 40.6 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property-offense composition
Larceny-theft is 84.2% of reported property offenses in McHenry, against a cohort median of 70.2%. The remainder is burglary (21) and motor vehicle theft (7). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 94.5 reported violent offenses per 100,000 residents in 2024, McHenry ranks 258 of 506 — above 248 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is -6.1% against the cohort median of 100.7. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property counts dominate McHenry'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 27 reported violent incidents in a population of 28,563. 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.
