A project of the NYU Furman Center, FloodzoneData.us describes the people and housing located in the U.S. floodplain.
FloodzoneData.us combines data from multiple sources to describe the housing stock and population in the nation's floodplain. Data at the national, state, county, and Census tract level are available for download.
Housing indicators include information on the number and share of residential units and buildings in the floodplains, how much housing is renter occupied or owner occupied, how much of the housing is multifamily or single-family, and information about the age and subsidy status of buildings in the floodplain. Population indicators include information on race and ethnicity, households with children, households with seniors, and household income for households in the floodplains.
