In conjunction with the launch of FloodzoneData.us, the NYU Furman Center released a series of data briefs to illustrate the housing and population located in the U.S. floodplains. The third brief in the series, Population and Housing in the Floodplain Battered by Hurricanes Harvey and Irma, 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.
In conjunction with the launch of FloodzoneData.us, the NYU Furman Center released a series of data briefs to illustrate the housing and population located in the U.S. floodplains. The second brief in the series, Population in the U.S. Floodplains, 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.
This brief, presented in conjuction with FloodzoneData.us 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 United States were located in the 100-year floodplain, and 10 percent were located in combined (100- and 500-year) floodplains. The 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.
