n=55 · window 2021-2025

near broadly near the state rate

95% range: 3.5–6.0
2.1%

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

n=247 · window 2021-2025

below somewhat below the state share

95% range: 1.8%–2.4%

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

19.6%

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

n=9 · window 2021-2024

well below possibly well below the state share

95% range: 10.7%–33.2%
26.1%

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

n=12 · window 2021-2024

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

n=12 · window 2021-2024

below somewhat below the state share

95% range: 15.6%–40.3%

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

214.4

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

n=2365 · window 2025

near near the state rate

215.1

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

n=11864 · window 2021-2025

near near 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

1.03

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

n=163 · window 2021-2023

near broadly near the state level

95% range: 0.88–1.20

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