Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Sammamish reported 18 violent offences in 2024 against a population of 64,358. 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.
Position in the state cohort
At 28.0 reported violent offenses per 100,000 residents in 2024, Sammamish ranks 149 of 164 — above 15 of the 163 other Washington cities whose 2024 submission passes this site’s completeness test. That is -85.0% 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.
Comparable rate records
The nearest comparable 2024 records to Sammamish's 28.0 violent-crime rate per 100,000 are Black Diamond (27.3), Raymond (30.6), Zillah (32.2), Clyde Hill (32.7). 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 4.9% of the 365 Part I offenses reported in Sammamish for 2024, against a median of 9.3% across comparable Washington cities — a gap of 4.4 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 26.9 per 100,000 in 2020 to 28.0 in 2024 (+3.9%). The highest observed value was 63.9 in 2022 and the lowest 26.9 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Sammamish'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 18 reported violent incidents in a population of 64,358. 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.
On a large city row, these are citywide reported offense totals - not neighbourhood advice. Conditions vary by place and time; reporting rates differ across jurisdictions.
