Decatur, IN carries a PlainCrime A safety grade with violent crime 52% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Decatur, IN shows violent crime at 169.1 per 100,000 residents and property crime at 676.4 per 100,000. Violent crime runs 52% below the U.S. average. PlainCrime assigns grade A from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Decatur reported 17 violent offences in 2024 against a population of 10,053. 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 Decatur's 169.1 violent-crime rate per 100,000 are Tipton (172.1), Speedway (161.6), Tell City (160.4), Albion (179.9). 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 20.0% of the 85 Part I offenses reported in Decatur for 2024, against a median of 13.5% across comparable Indiana cities — a gap of 6.5 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.
Position in the state cohort
At 169.1 reported violent offenses per 100,000 residents in 2024, Decatur ranks 55 of 113 — above 58 of the 112 other Indiana cities whose 2024 submission passes this site’s completeness test. That is +8.9% against the cohort median of 155.3. 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 Decatur'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 17 reported violent incidents in a population of 10,053. 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.
