FEMA publishes its new National Risk Index

The National Risk Index is a new, online mapping application from FEMA that identifies communities most at risk to 18 natural hazards. This application visualizes natural hazard risk metrics and includes data about expected annual losses, social vulnerabilities and community resilience.

The National Risk Index's interactive web maps are at the county and census tract level and made available via geographic information system (GIS) feature services for custom analyses. With this data, you can discover a holistic view of community risk to natural hazards via online maps and data.
