Offense mix
Violent offenses are 50.0% of the 6 Part I offenses reported in Sullivan for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 38.8 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.
Small-count caution
Sullivan reported 3 violent offences in 2024 against a population of 4,230. 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 812.5 per 100,000 in 2020 to 70.9 in 2024 (-91.3%). The highest observed value was 812.5 in 2020 and the lowest 0.0 in 2021. 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 Sullivan's 70.9 violent-crime rate per 100,000 are Roxana (71.3), Peotone (71.5), Knoxville (71.7), Bloomingdale (71.8). 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 70.9 reported violent offenses per 100,000 residents in 2024, Sullivan ranks 306 of 506 — above 200 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is -29.6% against the cohort median of 100.7. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Sullivan's FBI UCR Table 8 municipal row keeps violent and property totals in a closer balance. Per-100,000 rates use the reporting-year population on that row; incomplete reporters 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 4,230. 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.
