Iowa fatal crashes in 2024

FARS records 356 deaths in 324 fatal crashes in Iowa in 2024.

In 2023 it records 379 deaths in 330 fatal crashes.

In 2024 the rate is 11.0 deaths for each 100,000 residents in Iowa and 11.5 in the United States.

By deaths for each 100,000 residents in 2024, Iowa was number 30 of 51, the 50 states and the District of Columbia.

Deaths in Iowa fell by 6.1% from 2023 to 2024. In the United States they fell by 4.3%.

In 2024, a driver was recorded as drinking in 23.1% of fatal crashes in Iowa and 24.8% 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.
