Small-count caution
Mount Vernon-Lisbon reported 9 violent offences in 2024 against a population of 4,555. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
Comparable rate records
The nearest comparable 2024 records to Mount Vernon-Lisbon's 197.6 violent-crime rate per 100,000 are Camanche (198.0), Iowa Falls (201.0), Clarence (201.4), West Burlington (190.5). 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.
Property-offense composition
Larceny-theft is 50.0% of reported property offenses in Mount Vernon-Lisbon, against a cohort median of 76.8%. The remainder is burglary (10) and motor vehicle theft (2). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Offense mix
Violent offenses are 27.3% of the 33 Part I offenses reported in Mount Vernon-Lisbon for 2024, against a median of 15.8% across comparable Iowa cities — a gap of 11.5 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.
Position in the state cohort
At 197.6 reported violent offenses per 100,000 residents in 2024, Mount Vernon-Lisbon ranks 59 of 148 — above 89 of the 147 other Iowa cities whose 2024 submission passes this site’s completeness test. That is +38.4% against the cohort median of 142.7. 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 Mount Vernon-Lisbon'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.
Based on 9 reported violent incidents in a population of 4,555. At this volume, one additional or one fewer report can shift the rate and letter grade noticeably; small-city crime counts are inherently more volatile year to year than large-city counts, so treat this grade as a data point, not a precise ranking.
Small-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
Mount Vernon-Lisbon leans on larceny-theft at 36% of reported offenses, with a moderate mix index of 2,691.
Violent offenses are 27% of the municipal total; property offenses still dominate the count.
