How the Stone Score works
Experimental estimated housing-exposure index, not a damage rating. Each housing unit is assigned to its highest mapped size band using Census block points; housing units are not a count of individual buildings.
- 1 stone: qualifying local exposure below the higher tiers.
- 2 stones: 100+ units at 1.5″+, or 1,000+ at 1″+.
- 3 stones: 1,000+ units at 1.5″+, or 500+ at 2″+.
- 4 stones: 5,000+ units at 1.5″+, or 2,000+ at 2″+.
- 5 stones: 5,000+ units at 2″+.
Local pages require 100+ units at 1″+, or 25+ at 1.5″+. The highest qualifying tier wins. Unrated means insufficient qualifying exposure or missing data—not no damage.
