According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Nauvoo, IL shows violent crime at 218.1 per 100,000 residents and property crime at 436.2 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Nauvoo reported 2 violent offences in 2024 against a population of 917. 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.
Offense mix
Violent offenses are 33.3% of the 6 Part I offenses reported in Nauvoo for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 22.1 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.
Comparable rate records
The nearest comparable 2024 records to Nauvoo's 218.1 violent-crime rate per 100,000 are South Jacksonville (219.6), Effingham (220.5), Hometown (220.8), Glenwood (220.9). 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 218.1 reported violent offenses per 100,000 residents in 2024, Nauvoo ranks 132 of 506 — above 374 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +118.8% against the cohort median of 99.7. 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 Nauvoo'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 2 reported violent incidents in a population of 917. 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.
On a small municipal row, small denominators make rates sensitive to a handful of incidents. Figures are reported totals, not neighbourhood advice.
