This site gives no rate for the years before 2000.
Deaths in South Dakota fell by 22.4% from 1980 to 1981. In the United States they fell by 3.5%.
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. NHTSA's definitions
NHTSA says that its count of drinking drivers is unreliable for 1977, 1981 and 1999 to 2007, because it was derived in a wrong way. This site gives no count for these years.
For the years before 2015 the count is from the FARS element DRUNK_DR. It counts a blood alcohol concentration of .01 g/dL or more. From 2015 the count is from DR_DRINK and counts .001 g/dL or more.
