Small-count caution
Oconomowoc reported 3 violent offences in 2024 against a population of 18,830. 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 87.6 per 100,000 in 2020 to 15.9 in 2024 (-81.8%). The highest observed value was 87.6 in 2020 and the lowest 15.9 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 15.9 reported violent offenses per 100,000 residents in 2024, Oconomowoc ranks 200 of 222 — above 22 of the 221 other Wisconsin cities whose 2024 submission passes this site’s completeness test. That is -85.3% against the cohort median of 108.1. 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 Oconomowoc's 15.9 violent-crime rate per 100,000 are Whitefish Bay (13.8), Muskego (11.8), Plover (21.0), East Troy (21.2). 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 4.9% of the 61 Part I offenses reported in Oconomowoc for 2024, against a median of 12.1% across comparable Wisconsin cities — a gap of 7.2 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 counts dominate Oconomowoc'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 3 reported violent incidents in a population of 18,830. 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.
