FARS records 310 deaths in 285 fatal crashes in Connecticut in 2024.

In 2024 the rate is 8.4 deaths for each 100,000 residents in Connecticut and 11.5 in the United States.

In 2024 the rate is 1.00 deaths for each 100 million vehicle-miles in Connecticut and 1.19 in the United States.

By deaths for each 100,000 residents in 2024, Connecticut was number 43 of 51, the 50 states and the District of Columbia.

Deaths in Connecticut rose by 0.6% from 2023 to 2024. In the United States they fell by 4.3%.

From 2015 to 2024, 14.4% of the fatal crashes in Connecticut with a known setting were rural, against 42.7% in the United States.

To qualify as a FARS case, the crash had to involve a motor vehicle traveling on a trafficway customarily open to the public and must have resulted in the death of a motorist or a non-motorist within 30 days of the crash.

The set of first files, known as the Annual Report File (ARF), is released following the crash year. The ARF is replaced about a year later with a final file, which contains additional cases or updates to cases that had become available after the ARF was released.

The limits of the classes are the same for every state. A county with few residents can show a high rate from few deaths. A class is not a judgement of a county.

In words: 5 counties have a rate of fewer than 10; 3 counties have a rate of 10 to 14.9; 0 counties have a rate of 15 to 19.9; 0 counties have a rate of 20 to 29.9; 0 counties have a rate of 30 or more. Table 1 has the rate of each county.

Two rates

One rate divides the deaths by the residents. The other rate divides the deaths by the miles that vehicles travel in the state.

Note: FARS records a driver as drinking when police reported alcohol involvement or a test of the driver was positive for alcohol. It is not NHTSA's alcohol-impaired measure, which uses a blood alcohol concentration of .08 g/dL or higher. One crash can be in two or more rows. NHTSA's definitions

Note that alcohol data is often missing. For that reason, this data element may under-count the actual number of drinking drivers.
