The verdict
Byron earns an A safety grade: violent crime runs 70% below the U.S. average, placing it close to the national middle for violent crime.
Based on 4 reported violent incidents in a population of 3,768. 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
Byron reported 4 violent offences in 2024 against a population of 3,768. 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.
Comparable rate records
The nearest comparable 2024 records to Byron's 106.2 violent-crime rate per 100,000 are Barrington (105.7), Crystal Lake (104.7), Sesser (108.2), Tinley Park (108.9). 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.
Offense mix
Violent offenses are 28.6% of the 14 Part I offenses reported in Byron for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 17.4 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.
Property-offense composition
Larceny-theft is 90.0% of reported property offenses in Byron, against a cohort median of 70.2%. The remainder is burglary (0) and motor vehicle theft (1). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 106.2 reported violent offenses per 100,000 residents in 2024, Byron ranks 246 of 506 — above 260 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +6.5% 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 counts dominate Byron'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.

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.
