What the 2024 FBI UCR record shows for Arlington Heights, IL
Comparable rate records
Arlington Heights's closest reported-rate comparisons are in the Illinois cohort
The nearest comparable 2024 records to Arlington Heights's 50.3 violent-crime rate per 100,000 are Barrington Hills (50.1), Glen Ellyn (49.7), Dwight (49.6), Highland Park (49.5). 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.
Position in the state cohort
Arlington Heights sits mid-pack among comparable Illinois cities
At 50.3 reported violent offenses per 100,000 residents in 2024, Arlington Heights ranks 350 of 506 — above 156 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is -50.0% 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.
Offense mix
The reported mix leans further toward property offenses than the state cohort
Violent offenses are 5.4% of the 684 Part I offenses reported in Arlington Heights for 2024, against a median of 11.3% across comparable Illinois cities — a gap of 5.9 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.
2020–2024 direction
The reported violent-crime rate ended the window lower
Across 5 comparable reporting years, the rate moved from 57.6 per 100,000 in 2020 to 50.3 in 2024 (-12.6%). The highest observed value was 86.4 in 2023 and the lowest 42.0 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Arlington Heights'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.
On a large city row, these are citywide reported offense totals - not neighbourhood advice. Conditions vary by place and time; reporting rates differ across jurisdictions.
