FEMA National Risk Index

FEMA's National Risk Index (NRI) is a comprehensive dataset designed to assess and quantify risks associated with various natural hazards and socioeconomic factors across the United States. It integrates extensive datasets from federal, state, local, and private sources to provide a holistic understanding of the vulnerabilities and potential impacts of natural disasters. The NRI covers 18 different perils, including hurricanes, floods, earthquakes, wildfires, and more. By combining hazard intensity, exposure data, and vulnerability factors, it calculates risk scores and rankings to inform decision-making, disaster preparedness, and resilience-building efforts at local, regional, and national levels. The NRI plays a pivotal role in enhancing risk management and reducing the impact of disasters on communities and infrastructure.

The National Risk Index datasets have been uploaded by Kipi.ai to provide Snowflake customers with easier access to the data. The data is from the latest available update “Dataset Update 1.19.0 - 3/23/2023”. The data will be updated as new updates are released from FEMA.
