Risk Overview

About Natural Disaster Risk in Graham County, Arizona

Graham County has low overall risk

Graham County scores 64.60 on the composite risk scale, placing it in the "Relatively Low" category and well below Arizona's state average of 84.45. The southeastern county enjoys one of Arizona's safer natural hazard profiles.

Safer than most Arizona counties

Graham County ranks among Arizona's lower-risk counties, significantly outperforming the state average. Its 64.60 score positions it as one of the safest areas in the state for natural disaster exposure.

Safer than surrounding counties

Graham County's 64.60 score is substantially lower than Cochise County (92.84) to the east and Apache County (78.78) to the north. Its favorable position makes it one of southeastern Arizona's most protected areas.

Wildfire remains the primary concern

Graham County's main hazard is wildfire risk, which scores 94.27 despite the county's overall low composite rating. Flood risk (67.94) is also present but secondary; together these two hazards drive most of the county's natural disaster exposure.

Wildfire insurance is the priority

While Graham County's overall risk is low, wildfire coverage should still be a priority given the 94.27 risk score. Standard homeowners policies typically exclude wildfire, making supplemental or specialized insurance essential for property protection.
