Counties by historical claims

Sorted by total claims, highest first. Historical totals do not capture uninsured properties or future climate shifts.

How to read this

Historical claims show where NFIP-insured properties have actually filed. They under-count uninsured properties and don't forecast future risk from climate, upstream development, or new mitigation projects. For parcel-specific flood-zone designations, use FEMA's Map Service Center.
