Population in the U.S. floodplains

This brief examines the more than 30 million people living in the combined U.S. floodplains (100-year or 500- year floodplain) in 2011-2015, looking at characteristics such as age, race and ethnicity, and poverty. It also takes a closer look at how the population living in the floodplain varies by state. This information shows who is likely to bear the eventual cost of flooding, which can help policymakers plan the most effective and geography-specific disaster prevention and readiness programs.
