n=11 · window 2016-2025

well below possibly well below the state share

95% range: 0.1%–0.3%

Share of reported crashes that were fatal: 14.3 per 1,000, 2016-2025

n=102 · window 2016-2025

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.

99.7

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

n=726 · window 2025

above somewhat above the state rate

94.5

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

n=3441 · window 2021-2025

near broadly near the state rate

95% range: 91.4–97.7

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

1.63

Truck-crash share relative to overall reported-crash share, 2015-2023

n=664 · window 2015-2023
