What the Data Shows

New Haven County, Connecticut recorded 662 total road fatalities across 623 reported crashes during the 2016-2023 reporting window, according to NHTSA's Fatality Analysis Reporting System. The most recent year covered by the data logged 71 deaths on county roads, and the annual average works out to approximately 73.6 fatalities per year. Per-capita rates are not reported for every county in the FARS dataset; raw counts should therefore be compared against population and road-mile denominators from the state page.

Cause-code breakdowns are not individually published for New Haven County in the current FARS release, so readers looking for contributing-factor data should use the Connecticut state page, which aggregates county-level case files into statewide totals. Either way, the underlying records are drawn from a census of fatal crashes, not a statistical sample, so the counts are actual deaths rather than estimates.

The directional trend for New Haven County is increasing, which means annual fatalities have risen across the reporting period and may warrant closer attention from local transportation and enforcement agencies. Residents, insurers, and policy analysts can use this baseline alongside population density, highway mile data, and rural-versus-urban road mix to judge whether New Haven County's 662-death total is proportionate to its exposure. All numbers are for research and informational use only.
