No one died in a crash on Dewey’s roads in 2019–2023
That is about what is typical for Montana towns of 2,500–5,000 people: at their median rate (0.0 deaths per 100,000 residents a year), a town of Dewey’s size would see about 0 in five years. With numbers this small, a death or two either way changes the picture, so Dewey’s own rate (0.0) 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.
- A county agency covers a wide area. Its totals mix many communities, so they say little about any one of them.
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
