Auburn, IL is higher-crime than most U.S. cities, and earns a B PlainCrime safety grade, where violent crime runs 36% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Auburn, IL shows violent crime at 226.7 per 100,000 residents and property crime at 498.8 per 100,000. Violent crime runs 36% below the U.S. average. PlainCrime assigns grade B from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Auburn reported 10 violent offences in 2024 against a population of 4,411. 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 31.3% of the 32 Part I offenses reported in Auburn for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 20.0 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 Auburn's 226.7 violent-crime rate per 100,000 are Peru (226.0), Mahomet (227.7), Litchfield (228.4), Olney (224.8). 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 226.7 reported violent offenses per 100,000 residents in 2024, Auburn ranks 123 of 506 — above 383 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +127.5% 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-offense composition
Larceny-theft is 50.0% of reported property offenses in Auburn, against a cohort median of 70.3%. The remainder is burglary (11) and motor vehicle theft (0). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 260.8 per 100,000 in 2020 to 226.7 in 2024 (-13.1%). The highest observed value was 260.8 in 2020 and the lowest 22.5 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Auburn'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 10 reported violent incidents in a population of 4,411. 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.
Across 4.1 Census sq mi, Auburn logged 5.3 property and 2.4 violent offenses per square mile in 2024.
