Crash-location fatalities minus resident deaths, 2018-2024

n=121 · window 2018-2024

location minus resident A signed difference between the two source counts.

Keep in view: This difference is not a count of people traveling into or out of the county and does not identify where county residents crashed.

Crash severity

3.0

Share of reported crashes that were fatal: 3.0 per 1,000, 2021-2025

n=71 · window 2021-2025

well below possibly well below the state rate

95% range: 2.3–3.8
2.0%

Suspected-serious share of the source-defined reported-crash injury universe, 2021-2025

n=483 · window 2021-2025

below somewhat below the state share

95% range: 1.9%–2.2%

Keep in view: The share of reported crashes that were fatal does not measure a county's danger, a traveler's risk, or the cause of any crash.

Fatal-crash timing

31.7%

Share of FARS fatal crashes that were night, 2021-2024

n=19 · window 2021-2024

below somewhat below the state share

95% range: 21.3%–44.2%
28.3%

Share of FARS fatal crashes that were weekend, 2021-2024

n=17 · window 2021-2024

95% range: 18.5%–40.8%
21.7%

Share of FARS fatal crashes that were impaired involved, 2021-2024

n=13 · window 2021-2024

well below possibly well below the state share

95% range: 13.1%–33.6%

Keep in view: These time and involvement shares describe fatal crashes in FARS and do not measure an individual's risk or establish why a crash occurred.

Population context

209.8

Annual reported crashes per 10,000 residents (2024 ACS population), 2025

n=5245 · window 2025

near near the state rate

188.9

Five-year annualized reported crashes per 10,000 residents (2024 ACS population), 2021-2025

n=23610 · window 2021-2025

below below the state rate

Keep in view: Crashes per resident use population as context, not miles traveled, and do not measure an individual resident's driving risk.

Truck-crash context

1.07

Truck-crash share relative to overall reported-crash share, 2021-2023

n=316 · window 2021-2023

near broadly near the state level

95% range: 0.95–1.19

Keep in view: This location quotient compares shares of reported crashes and does not measure truck-driver fault, carrier safety, or roadway danger.
