In the past 10 years, the program has radically expanded to cover $1.1 trillion in assets today. This paper provides a detailed analysis of the largest flood insurance sample ever studied by focusing on the state of Florida, which accounts for 40 percent of the entire NFIP portfolio. We study the demand for flood insurance with a database of more than 7.5 million flood policies-in-force for the years 2000-2005, and all the claims filed in Florida during that period.
