American Falls, ID is higher-crime than most U.S. cities, and earns a B PlainCrime safety grade, where violent crime runs 24% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, American Falls, ID shows violent crime at 267.7 per 100,000 residents and property crime at 288.2 per 100,000. Violent crime runs 24% 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
American Falls reported 13 violent offences in 2024 against a population of 4,857. 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 48.1% of the 27 Part I offenses reported in American Falls for 2024, against a median of 21.6% across comparable Idaho cities — a gap of 26.6 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 American Falls's 267.7 violent-crime rate per 100,000 are Chubbuck (265.1), Parma (276.8), St. Maries (278.8), Kellogg (280.6). 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 186.1 per 100,000 in 2020 to 267.7 in 2024 (+43.8%). The highest observed value was 300.4 in 2022 and the lowest 140.2 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 267.7 reported violent offenses per 100,000 residents in 2024, American Falls ranks 19 of 55 — above 36 of the 54 other Idaho cities whose 2024 submission passes this site’s completeness test. That is +39.0% against the cohort median of 192.6. 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 64.3% of reported property offenses in American Falls, against a cohort median of 77.0%. The remainder is burglary (4) and motor vehicle theft (1). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
American Falls's FBI UCR Table 8 municipal row keeps violent and property totals in a closer balance. Per-100,000 rates use the reporting-year population on that row; incomplete reporters stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
Based on 13 reported violent incidents in a population of 4,857. 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.
