Natural-hazard score
What this number means, its source and the limits of using it.
Guide updated · Source dates are shown in the app
Say you want to flag a place for a closer hazard check. FEMA’s combined risk measure is broad screening information, not a parcel inspection or an insurance quote.
Reading the number
Group: Risk. Units: NRI composite score. Read the selected geography and compare the same measure at the same level.
Source and date
FEMA National Risk Index. Expected interval: about 365 days. This is a schedule, not proof that a refresh succeeded.
A guide update is not a data refresh. The source period and collection date, when available, are on the app’s data details. A missing date is unknown, never today. Check freshness.
Access and limits
Buyer and above by default. The app’s current lock is authoritative if settings change. Derived measures also need their input measures open. A missing number is not zero. What each plan shows.
