National Flood Insurance Program

The U.S. federal program administered by FEMA that writes flood insurance policies and pays claims for insured properties.

Four datasets in this slice expose NFIP geodata, redacted claims (2.72 million records since 1970) and redacted policies (73.6 million transactions since 2009).

In this catalog it appears concretely: - FEMA NFIP Geospatial Hub — "nfip, fema, floodplain". - FEMA NFIP Redacted Claims v2 — "2,721,780 claim records, loss dates 1970-08-31 to present". - FEMA NFIP Redacted Policies v2 — "73,601,802 policy transactions, effective dates 2009-01-01 to present". - OpenFEMA Data Sets Hub — "nfip-claims, nfip-policies, flood-insurance".

Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and FEMA NFIP Geospatial Hub lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open FEMA NFIP Geospatial Hub and confirm its record — "nfip, fema, floodplain" — against the files you actually receive.
2. Open FEMA NFIP Redacted Claims v2 and confirm its record — "2,721,780 claim records, loss dates 1970-08-31 to present" — against the files you actually receive.
3. Open FEMA NFIP Redacted Policies v2 and confirm its record — "73,601,802 policy transactions, effective dates 2009-01-01 to present" — against the files you actually receive.
