n=21 · window 2016-2025

well below possibly well below the state share

95% range: 0.1%–0.3%

Keep in view: These reported-crash flags can overlap and do not measure how often individual drivers engage in a behavior or establish why a crash happened.

Share of reported crashes that were fatal: 11.6 per 1,000, 2016-2025

n=110 · 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.

Population context

92.7

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

n=984 · window 2025

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

n=4665 · window 2021-2025

0.97

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

n=521 · window 2015-2023

near broadly near the state level
