What this page shows, and what it misses

FEMA's National Risk Index compares every US county with every other for 18 natural hazards, combining expected losses with social vulnerability and community resilience. It is a planning-level estimate for nationwide comparison, not a flood-zone map and not the risk to any one property — for flood zones use FEMA's Flood Map Service Center ↗. Federal declarations exclude state declarations and SBA or USDA designations.
