About State-Level Data

State-level summaries and charts on this page are derived from authoritative data that assigns costs to each affected state for every billion-dollar disaster. Those state-specific costs are shown only as binned ranges. The event cards and table list each disaster's full event cost rather than an exact state allocation.

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.
