Monthly tracking of what Americans pay for NFIP flood insurance, nationally and in every state, built from FEMA OpenFEMA NFIP policy transaction data (NFIP Redacted Policies v3). What we measure: Average premium among policies newly written or renewed that month (NFIP transactions) — not the official in-force average. OpenFEMA transaction data is published on a lag of roughly two months; the latest period shown reflects that lag.

How this index is built
We aggregate monthly policy transactions from FEMA OpenFEMA NFIP policy transaction data (NFIP Redacted Policies v3). For each month we average the premium across policies that became newly effective or renewed in that month — a cost-trend proxy, not the official in-force average that FEMA publishes separately. OpenFEMA transaction data is published on a lag of roughly two months; the latest period shown reflects that lag.
