This analysis explores the U.S. National Oceanic and Atmospheric Administration’s (NOAA) storm database to identify the types of severe weather events that are most harmful to population health and have the greatest economic consequences. The data spans events from 1950 to 2011. The raw dataset is cleaned, and only events with injuries, fatalities, or economic damage are considered. Events are grouped and standardized for clarity. Health impacts are evaluated by summing injuries and fatalities, while economic impacts are measured by property and crop damage. The results indicate tornadoes cause the most health-related harm, while floods result in the highest economic damage.
