Estimates of economic losses from natural hazards involving floods from three national databases. Figures on the left represent the natural logarithm of annual losses; figures on the right represent these losses as a percent of the US gross domestic product. All estimates have been converted to 2007 dollars using the consumer price index. Data are compiled from: (a) national flood damages (excluding those associated with coastal storm surges); (b) losses from the deadliest, costliest, and most intense US tropical cyclones; and (c) paid flood insurance losses from significant flood events. Please see the text for a description of coverage, gaps, and overlaps.
