Position in the state cohort
At 247.4 reported violent offenses per 100,000 residents in 2024, Mount Vernon ranks 112 of 506 — above 394 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +148.2% 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.
Offense mix
Violent offenses are 18.5% of the 189 Part I offenses reported in Mount Vernon for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 7.3 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.
Property-offense composition
Larceny-theft is 86.4% of reported property offenses in Mount Vernon, against a cohort median of 70.2%. The remainder is burglary (16) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Mount Vernon'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.
