What the 2024 FBI UCR record shows for Janesville, WI
Comparable rate records
Janesville's closest reported-rate comparisons are in the Wisconsin cohort
The nearest comparable 2024 records to Janesville's 143.4 violent-crime rate per 100,000 are Beaver Dam (145.7), Saukville (140.8), Oak Creek (146.0), Hales Corners (146.4). 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.
2020–2024 direction
The reported violent-crime rate ended the window lower
Across 5 comparable reporting years, the rate moved from 224.2 per 100,000 in 2020 to 143.4 in 2024 (-36.0%). The highest observed value was 230.1 in 2021 and the lowest 143.4 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
Janesville sits mid-pack among comparable Wisconsin cities
At 143.4 reported violent offenses per 100,000 residents in 2024, Janesville ranks 82 of 222 — above 140 of the 221 other Wisconsin cities whose 2024 submission passes this site’s completeness test. That is +34.0% against the cohort median of 107.1. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
The reported mix leans further toward property offenses than the state cohort
Violent offenses are 7.2% of the 1,315 Part I offenses reported in Janesville for 2024, against a median of 12.1% across comparable Wisconsin cities — a gap of 4.8 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 Janesville'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.
On a large city row, these are citywide reported offense totals - not neighbourhood advice. Conditions vary by place and time; reporting rates differ across jurisdictions.
