A project of the NYU Furman Center, FloodzoneData.us describes the people and housing located in the U.S. floodplain.
Data briefs by the NYU Furman Center presented in conjunction with FloodzoneData.us.
(May 2017) This brief describes characteristics about the housing stock located in the U.S. floodplains. Between 2011 and 2015, five percent of all occupied housing units in the U.S. were located in the 100-year floodplain, and 10 percent were located in combined (100- and 500-year) floodplains. This brief details factors that are important to understand when assessing the risk from flooding and the challenges of retrofitting, including the shares that are rental and owner-occupied, the age of the housing, and whether the housing is government subsidized.
(December 2017) The second brief in the series explores the characteristics of the population located in the 100-year floodplain and the combined floodplain (100-year and 500-year floodplain), nationwide. In 2015, more than 30 million people (10% of the U.S. population) lived in the combined floodplain.
(December 2017) The third brief in the series describes the housing and population located in the floodplains of metropolitan areas affected by hurricanes in recent months, including Houston, Miami, Tampa, and Jacksonville. The analysis describes the housing stock (including tenure, size, and number of subsidized housing units) and population demographics (including poverty rates, households with children and seniors, and race/ethnicity) in floodplains within these metro areas.
