FARS data are based on police crash reports and other sources; the drunk-driving measure is based on the highest BAC of any driver in the crash. Latest data year: 2024. Figures are aggregates from NHTSA's Fatality Analysis Reporting System; no individual crash is identified.
NHTSA's FARS file lists 6 people killed in 6 fatal crashes in Decatur County, Kansas, between 2015 and 2024, no of them in 2024.
With 2,716 residents, that is 21.5 deaths per 100,000 people a year over the ten years, 56% higher than the Kansas rate of 13.8 and above the national rate of 11.8. The rate rests on very few deaths and can double or halve with a single crash; through traffic on a route that passes a small population raises it further.
Counts this small move a lot from year to year, so the page shows ten-year totals and five-year bins rather than single years; 2005–2014 had 8 deaths.
Trend since 1975
Ten-year total down 25% (8 in 2005–2014, 6 in 2015–2024). The shaded band is the ten-year window used for rates and shares. County codes are matched to today's Census county list; a few historic code changes are merged.

Factors
Too few fatal crashes (6 in ten years) to show factor shares; see the Kansas page for state-level shares.
"Alcohol" counts crashes where police reported at least one driver as drinking (FARS DR_DRINK), not the BAC-based alcohol-impaired measure NHTSA publishes separately. "Speeding" counts crashes with a driver coded as racing, exceeding the limit or too fast for conditions. Details in the methodology. Factor pages: alcohol, speeding, pedestrians, motorcycles, unrestrained occupants.
