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. New Trier covers 14 census tracts, combined by population.

Money that reached townFlood claims are matched to New Trier’s own flood-insurance community (here, the census tracts inside it); household aid to the registrant’s city; repair grants to the Township of New Trier. 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 New Trier total about $35.0M a year, counting buildings, people and crops.
