What the 2024 FBI UCR record shows for Crystal Lake, IL
Comparable rate records
Crystal Lake's closest reported-rate comparisons are in the Illinois cohort
The nearest comparable 2024 records to Crystal Lake's 104.7 violent-crime rate per 100,000 are Barrington (105.7), Byron (106.2), Coal City (103.2), Chatham (103.0). 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.
Property-offense composition
Larceny-theft dominates the property total more than it does across the cohort
Larceny-theft is 84.1% of reported property offenses in Crystal Lake, against a cohort median of 70.2%. The remainder is burglary (42) and motor vehicle theft (30). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
2020–2024 direction
The reported violent-crime rate ended the window higher
Across 4 comparable reporting years, the rate moved from 93.1 per 100,000 in 2020 to 104.7 in 2024 (+12.4%). The highest observed value was 105.2 in 2023 and the lowest 93.1 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
Crystal Lake sits mid-pack among comparable Illinois cities
At 104.7 reported violent offenses per 100,000 residents in 2024, Crystal Lake ranks 248 of 506 — above 258 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +5.0% against the cohort median of 99.7. 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 Crystal Lake'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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
