FARS records 465 deaths in 404 fatal crashes in Iowa in 1990.

In 1989 it records 514 deaths in 451 fatal crashes.

This site gives no rate for the years before 2000.

Deaths in Iowa fell by 9.5% from 1989 to 1990. In the United States they fell by 2.2%.

In 1990, a driver was recorded as drinking in 42.3% of fatal crashes in Iowa and 40.3% 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.
