Natural disaster rankings

Every ranking here measures one thing and says which: FEMA's declarations, the deaths and damage NOAA recorded, or days with a storm record per square mile. None combines measures into a score. The storm measures run through June 30, 2026, FEMA's declarations through October 2, 2026.
