According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Mill Creek, WA shows violent crime at 125.7 per 100,000 residents and property crime at 1,832.1 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Mill Creek reported 26 violent offences in 2024 against a population of 20,687. 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 Mill Creek's 125.7 violent-crime rate per 100,000 are Cle Elum (126.0), Selah (126.3), Algona (126.6), Gold Bar (124.4). 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 174.4 per 100,000 in 2020 to 125.7 in 2024 (-27.9%). The highest observed value was 216.4 in 2023 and the lowest 125.7 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 125.7 reported violent offenses per 100,000 residents in 2024, Mill Creek ranks 104 of 164 — above 60 of the 163 other Washington cities whose 2024 submission passes this site’s completeness test. That is -32.7% against the cohort median of 186.8. 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 Mill Creek'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 20,687. 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.
