In 2014 it records 322 deaths in 288 fatal crashes.

In 2015 the rate is 10.2 deaths for each 100,000 residents in Iowa and 11.1 in the United States.

By deaths for each 100,000 residents in 2015, Iowa was number 29 of 51, the 50 states and the District of Columbia.

Deaths in Iowa fell by 0.6% from 2014 to 2015. In the United States they rose by 8.4%.

In 2015, a driver was recorded as drinking in 29.1% of fatal crashes in Iowa and 28.3% 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.
