About This Dataset
Costliest Atlantic Hurricanes, Damage Normalized
Normalized damage restates each storm's bill as if it struck today, adjusting for inflation, population growth and the value of property now standing in its path. It is the only way to compare a storm from the 1920s with one from last year, and it reorders the ranking considerably.
Analysis
Katrina (2005) normalizes to $226.21 billion, against $125 billion in the dollars of its own year. 4 of the 12 storms here struck before 2000 - adjustment is what puts them on the chart. The largest gap between normalized and nominal damage belongs to Katrina, at $101 billion. The smallest figure on this chart is $48.33 billion.
