On crimes reported to the FBI by Dover’s police in 2023–2025, it grades A− for safety: #74 of 124 graded towns in New Hampshire.
Crimes reported to the FBI per 1,000 residents a year, 2023–2025. “Rest of NH” is every other New Hampshire 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.

Seven people died in crashes on Dover’s roads in 2019–2023
Dover had 6 fatal crashes in five years, in which seven people died; 2 were pedestrians.
That is about what is typical for New Hampshire towns of 25,000–100,000 people: at their median rate (4.7 deaths per 100,000 residents a year), a town of Dover’s size would see about 8 in five years. With numbers this small, a death or two either way changes the picture, so Dover’s own rate (4.2) 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 Dover. 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 Dover’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (34,157 in 2025); our figure for Dover is 34,623 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
