The county rows show FEMA's own county percentile scores and rating categories; the state figures above are our weighted means. County data cannot establish a property's safety. Expected loss is modeled annual loss per resident, not a premium quote. The insurance figure is what owners with a mortgage reported paying in 2024 (Census American Community Survey), not a current quote. For a specific home, check the address on FEMA's flood map and get insurance quotes before you commit. Our guide explains how to check natural disaster risk before you move.
