10 people died in crashes on Merrimack’s roads in 2019–2023
Merrimack had 9 fatal crashes in five years, in which 10 people died.
That is 7.1 deaths per 100,000 residents a year, above the median for New Hampshire towns of 25,000–100,000 people (4.7, 9 towns).
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 Merrimack. 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 Merrimack’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (30,040 in 2025); our figure for Merrimack is 29,699 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
