FEMA Disaster Declarations

Every federally-declared disaster since 1953 — DR (major disaster), EM (emergency), and FM (fire management) declarations, one record per designated county, with the assistance programs activated. The event dataset for insurance, construction, utilities, and muni-credit questions — and the front-end of federal rebuild money.
