Is FEMA flood claims data accessible on demand?

Yes. FEMA NFIP Redacted Claims v2 (OpenFEMA) costs nothing and needs no integration key: 2,721,780 claim records with loss dates back to August 31, 1970, refreshed monthly and downloadable in bulk as CSV (500MB-10GB class) or Parquet (50MB-500MB class). OpenFEMA terms restrict use to statistical research or reporting and prohibit reidentifying individuals.

How big is the NFIP claims CSV download?

The bulk CSV sits in the 500MB-10GB class holding 2,721,780 claim transactions across 74 documented fields. The Parquet alternative lands in the 50MB-500MB class and loads directly into Spark or DuckDB. Filtered subsets via the REST API come back as JSON, or as server-rendered CSV when you append $format=csv to the request.

Does the NFIP claims data include payment amounts?

Yes. Each record carries buildingDamageAmount and contentsDamageAmount alongside gross payments on building, contents and Increased Cost of Compliance claims, matching net payment amounts after deductions, deductible codes, insurance coverage totals and non-payment reason codes explaining claims that paid nothing.

Is the NFIP claims dataset being replaced?

Yes. V2 was frozen as of June 1, 2026 during deprecation and will be removed after October 15, 2026, when NfipRedactedClaims v3 resumes the monthly rebuild. Existing v2 extracts stay valid historical snapshots, but any pipeline needing post-June 2026 losses should migrate to the v3 endpoint now.

What fields does the NFIP claims file include?

All 74 documented fields carry verified definitions in Datadory's catalog, and they group into five clusters.

How far back does the claim history reach, and what can you benchmark it against?

Loss dates run from August 31, 1970 to the present - five decades of transaction-level flood losses, which is why severity trending is this table's signature use. Policy detail cannot match it: coverage starts January 1, 2009, so every catastrophe before 2009 exists only in claims, identified through floodEvent and eventDesignationNumber.
