About these numbers

How to read this page

An average, not a forecastFEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.

Compared by rate“Higher than N%” compares yearly damage as a share of what’s here, so a big city isn’t rated riskier just for having more buildings. Wilseyville covers 1 census tract, combined by population.

Money that reached townFlood claims are matched to Wilseyville’s own flood-insurance community (here, the census tracts inside it); household aid to the registrant’s city; repair grants to Wilseyville. FEMA’s model follows property values, so a place that recently lost many homes can rate lower than it feels.

FEMA’s expected losses across Wilseyville total about $5.9M a year, counting buildings, people and crops.
