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).
