Adams County, Idaho: fatal crash statistics

FARS records 1 or 2 deaths in 1 or 2 fatal crashes in Adams County in 2024.

FARS records 23 deaths in 20 fatal crashes in the county from 2015 to 2024.

From 2015 to 2024 the rate is 52.1 deaths for each 100,000 residents in a year.

The rate of Idaho in the same years is 13.1.

By deaths from 2015 to 2024, Adams County was number 28 of 44 counties of Idaho.

From 2015 to 2024, 100.0% of the fatal crashes in Adams County with a known setting were rural, against 74.5% in Idaho.

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.

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.
