Comparable rate records
The nearest comparable 2024 records to Arlington's 337.8 violent-crime rate per 100,000 are Renton (339.2), Soap Lake (341.1), Pasco (347.6), Bellingham (350.0). 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 337.8 reported violent offenses per 100,000 residents in 2024, Arlington ranks 39 of 164 — above 125 of the 163 other Washington cities whose 2024 submission passes this site’s completeness test. That is +83.7% against the cohort median of 183.9. 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 302.5 per 100,000 in 2020 to 337.8 in 2024 (+11.7%). The highest observed value was 407.2 in 2023 and the lowest 219.6 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 13.2% of the 553 Part I offenses reported in Arlington for 2024, against a median of 9.2% across comparable Washington cities — a gap of 4.0 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.
Property-offense composition
Larceny-theft is 65.4% of reported property offenses in Arlington, against a cohort median of 73.6%. The remainder is burglary (74) and motor vehicle theft (92). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Arlington'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.
