Overall, Ansonia grades B− for safety (#60 of 90 graded towns in Connecticut): close to the middle of U.S. towns, on crimes its police reported to the FBI in 2023–2025.
Crimes reported to the FBI per 1,000 residents a year, 2023–2025. “Rest of CT” is every other Connecticut 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.

What’s behind Ansonia’s grade
Property crimes plus four times violent crimes reported to the FBI per resident, 2023–2025, on a national curve. Violent crime holds Ansonia’s grade up; property crime pulls it down. Its property rate (15.4) is below the FBI’s national estimate (17.6) but higher than in most individual towns: the national figure is weighted by people, and the grade counts towns.
Violent crime, by year and by type
Ansonia’s police reported 36 violent crimes to the FBI over 2023–2025, about 0.6 per 1,000 residents a year, against 1.5 in the rest of Connecticut and the FBI’s national estimate of 3.6.

One person died in crashes on Ansonia’s roads in 2019–2023
Ansonia had 1 fatal crash in five years, in which one person died.
That is fewer than is typical for Connecticut towns of 5,000–25,000 people: at their median rate (7.5 deaths per 100,000 residents a year), a town of Ansonia’s size would see about 7 in five years. With numbers this small, a death or two either way changes the picture, so Ansonia’s own rate (1.1) 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 Ansonia. 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 Ansonia’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (19,271 in 2025); our figure for Ansonia is 19,216 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
