Position in the state cohort
At 468.7 reported violent offenses per 100,000 residents in 2024, Marion ranks 35 of 506 — above 471 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 Marion's 468.7 violent-crime rate per 100,000 are Summit (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.
2020–2024 direction
Across 3 comparable reporting years, the rate moved from 774.9 per 100,000 in 2020 to 468.7 in 2024 (-39.5%). The highest observed value was 774.9 in 2020 and the lowest 209.9 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property-offense composition
Larceny-theft is 56.5% of reported property offenses in Marion, against a cohort median of 70.3%. The remainder is burglary (186) and motor vehicle theft (29). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Marion'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.
