Green River, WY carries a PlainCrime B safety grade with violent crime 35% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Green River, WY shows violent crime at 228.2 per 100,000 residents and property crime at 623.1 per 100,000. Violent crime runs 35% 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
Green River reported 26 violent offences in 2024 against a population of 11,395. 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 Green River's 228.2 violent-crime rate per 100,000 are Gillette (197.0), Jackson (188.8), Saratoga (169.4), Casper (288.8). 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.
Offense mix
Violent offenses are 26.8% of the 97 Part I offenses reported in Green River for 2024, against a median of 12.5% across comparable Wyoming cities — a gap of 14.3 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 228.2 reported violent offenses per 100,000 residents in 2024, Green River ranks 10 of 28 — above 18 of the 27 other Wyoming cities whose 2024 submission passes this site’s completeness test. That is +67.4% against the cohort median of 136.3. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 265.2 per 100,000 in 2020 to 228.2 in 2024 (-14.0%). The highest observed value was 342.0 in 2023 and the lowest 192.4 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property-offense composition
Larceny-theft is 87.3% of reported property offenses in Green River, against a cohort median of 79.2%. The remainder is burglary (5) and motor vehicle theft (4). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Green River'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 26 reported violent incidents in a population of 11,395. 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.
