Position in the state cohort
At 468.7 reported violent offenses per 100,000 residents in 2024, Summit ranks 36 of 506 — above 470 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +370.2% 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.
Comparable rate records
The nearest comparable 2024 records to Summit's 468.7 violent-crime rate per 100,000 are Marion (468.7), Kansas (468.0), Fairmont City (465.5), Zion (452.9). 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 23.4% of the 209 Part I offenses reported in Summit for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 12.2 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
Across 4 comparable reporting years, the rate moved from 431.5 per 100,000 in 2020 to 468.7 in 2024 (+8.6%). The highest observed value was 468.7 in 2024 and the lowest 243.9 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Summit'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.
