Crimes reported to the FBI per 1,000 residents a year, 2023–2025. “Rest of WA” is every other Washington city and town in the FBI’s tables; the U.S. figure is the FBI’s national estimate as published, averaged over the three years. The FBI publishes no national homicide or robbery rate in our data, so those compare with all U.S. cities and towns in its tables.

One person died in crashes on Black Diamond’s roads in 2019–2023
Black Diamond had 1 fatal crash in five years, in which one person died.
That is about what is typical for Washington towns of 5,000–25,000 people: at their median rate (3.7 deaths per 100,000 residents a year), a town of Black Diamond’s size would see about 1 in five years. With numbers this small, a death or two either way changes the picture, so Black Diamond’s own rate (3.4) is context, not a ranking.
Deaths are counted where the crash happened, not where the people lived: a highway through town adds through-traffic deaths, and residents’ own risk on roads elsewhere isn’t here. Town rates sit below state and U.S. rates because a third of fatal crashes happen outside any town. Road safety is described here and is not part of the Safety Grade.

What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many crimes are never reported to police.
- One number for all of Black Diamond. A town-wide rate doesn’t show where incidents happen, and that can differ a lot from one part of town to another.
- Visitors count too. Incidents involving people who work, shop or visit are counted against Black Diamond’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (7,388 in 2025); our figure for Black Diamond is 6,978 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
