Residence and crash location

Deaths of county residents, CDC WONDER, 2018-2024

n=236 · window 2018-2024

Deaths from crashes in this county, FARS, 2018-2024

-24

Crash-location fatalities minus resident deaths, 2018-2024

n=212 · 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

3.8

Share of reported crashes that were fatal: 3.8 per 1,000, 2021-2025

n=156 · window 2021-2025

below somewhat below the state rate

95% range: 3.3–4.5
2.0%

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

n=814 · window 2021-2025

below somewhat below the state share

95% range: 1.9%–2.1%

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

42.6%

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

n=55 · window 2021-2024

near broadly near the state share

95% range: 34.4%–51.3%
32.6%

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

n=42 · window 2021-2024

near broadly near the state share

95% range: 25.1%–41.0%
30.2%

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

n=39 · window 2021-2024

near broadly near the state share

95% range: 23.0%–38.6%

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

210.9

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

n=8286 · window 2025

near near the state rate

206.6

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

n=40577 · 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

0.90

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

n=472 · window 2021-2023

near broadly near the state level

95% range: 0.82–0.99

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