2020–2024 direction
Across 5 comparable reporting years, the rate moved from 70.9 per 100,000 in 2020 to 184.3 in 2024 (+160.1%). The highest observed value was 284.9 in 2022 and the lowest 70.9 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Comparable rate records
The nearest comparable 2024 records to Sun Prairie's 184.3 violent-crime rate per 100,000 are Fennimore (181.4), Ripon (180.9), Delavan (188.3), Watertown (190.2). 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.
Position in the state cohort
At 184.3 reported violent offenses per 100,000 residents in 2024, Sun Prairie ranks 66 of 222 — above 156 of the 221 other Wisconsin cities whose 2024 submission passes this site’s completeness test. That is +72.2% 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.
Property counts dominate Sun Prairie'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.
