About State-Level Data
State-level cost estimates shown on this page are derived from authoritative data that assigns specific costs to each affected state for every billion-dollar disaster. Because many events span multiple states, the costs displayed here represent each state's specific share of the total event cost, providing an accurate picture of economic impacts at the state level.
Climate Central maintains this comprehensive database tracking U.S. weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including Consumer Price Index adjustment). As the steward of this dataset, Climate Central is committed to maintaining the scientific rigor and methodological standards established by NOAA's National Centers for Environmental Information (NCEI) while enhancing the dataset's utility for climate communication and public understanding of climate risks.
