Position in the state cohort
Marshalltown reported a higher violent-crime rate than most comparable Iowa cities
At 297.4 reported violent offenses per 100,000 residents in 2024, Marshalltown ranks 32 of 148 — above 116 of the 147 other Iowa cities whose 2024 submission passes this site’s completeness test. That is +108.4% 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.
2020–2024 direction
The reported violent-crime rate ended the window lower
Across 5 comparable reporting years, the rate moved from 481.9 per 100,000 in 2020 to 297.4 in 2024 (-38.3%). The highest observed value was 676.3 in 2022 and the lowest 297.4 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Marshalltown'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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
