Four people died in crashes on Londonderry’s roads in 2019–2023
Londonderry had 4 fatal crashes in five years, in which four 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 Londonderry’s size would see about 6 in five years. With numbers this small, a death or two either way changes the picture, so Londonderry’s own rate (3.0) 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.
- One number for all of Londonderry. 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 Londonderry’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (27,327 in 2025); our figure for Londonderry is 27,844 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
