Project Description

Project Title:  View help for Project Title FEMA National Risk Index
Summary:  View help for Summary
The National Risk Index is a dataset and online tool to help illustrate the United States communities most at risk for 18 natural hazards. It was designed and built by FEMA in close collaboration with various stakeholders and partners in academia; local, state and federal government; and private industry.
The Risk Index leverages available source data for natural hazard and community risk factors to develop a baseline risk measurement for each United States county and Census tract.

The 18 natural hazards included in the National Risk Index are:
In the National Risk Index, natural hazards are represented in terms of Expected Annual Loss, which incorporate data for exposure, annualized frequency, and historic loss ratio.

This dataset is represented in three different formats:
* Geodatabase - files with _GDB_ in the name are geodatabase format.
* Shape files - files with _Shapefile_ in the name are in shapefile format.
* CSV - files with _Table_ in the name are in CSV format.
