Method nfip-county-ranks-v1. Premium ranks sort the same 330 eligible county rows by average premium, then transaction count, then FIPS; the state rank uses that state's eligible subset. Volume rank sorts by transaction count, then FIPS. These ranks describe one source month and are not a score or recommendation.

Method and limitations

  • The figures describe policies newly written or renewed in June 2026; they are not FEMA's official average across all in-force policies.
  • Only named counties with matching state and five-digit FIPS codes, finite cost values, and at least 100 transactions enter the comparison population.
  • A monthly county average can change with the mix of properties renewing. It is not a household quote and does not include private flood insurance.
  • State and national values use the same transaction-based source month. A larger sample does not mean a lower or higher household price.
