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. Dummer is smaller than a census tract, so it shares the figures of the tract around its center.

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