Small-count caution
Dyersville reported 1 violent offences in 2024 against a population of 4,575. 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 114.8 per 100,000 in 2020 to 21.9 in 2024 (-81.0%). The highest observed value was 156.3 in 2021 and the lowest 21.9 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 21.9 reported violent offenses per 100,000 residents in 2024, Dyersville ranks 134 of 148 — above 14 of the 147 other Iowa cities whose 2024 submission passes this site’s completeness test. That is -85.1% against the cohort median of 146.3. 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 Dyersville's 21.9 violent-crime rate per 100,000 are Huxley (21.1), Waukon (26.6), Polk City (30.5), Mitchellville (37.6). 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 5.6% of the 18 Part I offenses reported in Dyersville for 2024, against a median of 15.9% across comparable Iowa cities — a gap of 10.3 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 58.8% of reported property offenses in Dyersville, against a cohort median of 76.8%. The remainder is burglary (3) and motor vehicle theft (4). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Dyersville'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 1 reported violent incidents in a population of 4,575. 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.
