Billion-Dollar Weather and Climate Disasters: Summary Stats

The distribution of damage from U.S. Billion-dollar disaster events across the 1980-2016 period of record (as of January 2017) is dominated by tropical cyclone losses. From 1980-2016, tropical cyclones have caused the most damage ($560.1 billion, CPI-adjusted) and also have the highest average event cost ($16.0 billion per event, CPI-adjusted). Drought ($223.8 billion, CPI-adjusted), severe storms ($180.1 billion, CPI-adjusted) and inland flooding ($110.7 billion, CPI-adjusted) have also caused considerable damage based on the list of billion-dollar events. Severe storms have caused the highest number of billion-dollar disaster events (83), while the average event cost is the lowest ($2.2 billion, CPI-adjusted). Tropical cyclones and flooding represent the second and third most frequent event types (35 and 26), respectively. Tropical cyclones are responsible for the highest number of deaths (3,210), followed by drought/heatwave events (2,993) and severe storms (1,546).
