Frequently Asked Questions
What is the FEMA National Risk Index?
The National Risk Index (NRI) is FEMA's county-level measure of natural disaster risk. It combines Expected Annual Loss across 18 hazard types (hurricane, tornado, wildfire, flood, and more) with Social Vulnerability and Community Resilience into a single composite score from 0 to 100.
Which parts of the US have the highest natural disaster risk?
The highest composite scores cluster along the hurricane-exposed Gulf and Atlantic coasts, the tornado- and hail-prone central Plains, and the wildfire- and earthquake-prone West. The lowest-risk counties are concentrated in the interior Northeast and upper Midwest.
