Iowa fatal crashes in 2011

FARS records 360 deaths in 329 fatal crashes in Iowa in 2011.

In 2010 it records 390 deaths in 348 fatal crashes.

In 2011 the rate is 11.7 deaths for each 100,000 residents in Iowa and 10.4 in the United States.

By deaths for each 100,000 residents in 2011, Iowa was number 22 of 51, the 50 states and the District of Columbia.

Deaths in Iowa fell by 7.7% from 2010 to 2011. In the United States they fell by 1.6%.

In 2011, a driver was recorded as drinking in 20.1% of fatal crashes in Iowa and 30.9% 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.
