How to read these ratings

Ratings run in five steps: very low, relatively low, relatively moderate, relatively high and very high. They compare a county with every other US county; they are not a measure of danger on their own.
Scores run from 0 to 100 and are national percentiles. The bar shows the score: a score of 80 means a higher value than 80% of US counties.
Overall risk combines the expected annual loss with social vulnerability and community resilience.
Expected annual loss is the average yearly loss to buildings, people and agriculture the model expects from all 18 hazards.
Social vulnerability describes how hard it may be for people to prepare for and recover from a disaster. Higher is worse.
Community resilience describes a community's ability to prepare, adapt and recover. Higher is better.
"Not applicable" means FEMA does not model that hazard there (for example, hurricanes far inland).
