The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.

Shenandoah County's composite risk score of 60th percentile is above the Virginia state average of 33th percentile. This elevated risk is driven by hurricane exposure (80th percentile), along with flooding and wildfire and earthquake risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
