This analysis explores the U.S. National Oceanic and Atmospheric Administration storm database to identify which severe weather events have had the largest effects on population health and the economy across the United States. Population health impact is measured using the combined number of fatalities and injuries recorded for each event type. Economic impact is measured using the combined property and crop damage estimates, after converting the damage exponent fields into numeric multipliers. The analysis starts from the original compressed raw CSV file and performs all processing inside this document. Event names are standardised to reduce differences caused by inconsistent capitalisation and spacing. The results show which event categories are most harmful to people and which categories cause the greatest economic damage. This provides a high-level view that could help municipal or government managers understand which weather events require the most attention when planning for public safety and disaster preparedness.
