Economic & Other Societal Impacts Related to Hurricanes, Floods, Tornadoes, Lightning, & Other Weather Phenomena

Tornado, Hurricane, and Flood Damage 1955 - 2006 (Sources)

The composite loss totals presented here are a sum of annual flood, tornado, and hurricane damages. In order to combine these events into a meaningful total, the time periods must be similar. Therefore, hurricane and tornado is only included for the years 1955-2006. The "Total Damages" column presents composite losses adjusted for inflation to $2006 U.S. Also, when wealth changes over time, the amount of assets vulnerable to extreme weather events also changes. Therefore, the "Total Wealth Adjusted Damages" column normalizes all loss values to account for national changes in wealth. Links to more information on adjustment methods, appropriate interpretation, and original data sources can be found on the Data & Methodology page.

It should be noted that there is no flood loss data for the years 1980-1982. Reliable data for these years does not exist due to a lack of funding for collecting flood loss data during this time period.
