This report explores the U.S. National Oceanic and Atmospheric Administration (NOAA) storm database, covering severe weather events from 1950 to November 2011. It investigates which types of events have the highest impact on public health, measured by fatalities and injuries, and which events lead to the greatest economic losses, measured by property and crop damages. Data was loaded directly from the original compressed CSV file and cleaned to standardize damage estimates. Tornadoes, heat, and floods emerge as key hazards for human health, while floods, hurricanes, and tornadoes cause major economic losses. All results are reproducible, and plots illustrate the main findings.

This analysis explores the NOAA Storm Database from 1950 to 2011 to determine which types of severe weather events are most harmful to population health and which cause the greatest economic consequences in the United States. The raw data was processed to calculate fatalities, injuries, and property/crop damages. Results show that tornadoes are the most dangerous to human health, while floods, hurricanes, and tornadoes cause the most economic loss. The purpose of this report is to support emergency preparedness decisions.
