The verdict
Assumption: among the safest cities in the country.
Based on 0 reported violent incidents in a population of 1,103. 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-count caution
Assumption reported 0 violent offences in 2024 against a population of 1,103. 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.
Position in the state cohort
At 0.0 reported violent offenses per 100,000 residents in 2024, Assumption ranks 418 of 506 — above 0 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is -100.0% 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.
Comparable rate records
The nearest comparable 2024 records to Assumption's 0.0 violent-crime rate per 100,000 are Albers (0.0), Annawan (0.0), Ashland (0.0), Bannockburn (0.0). 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.
Property counts dominate Assumption'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.
