Increases in coastal population growth by 2020 likely, putting more people at risk of extreme weather

News release: “If current population trends continue, the already crowded U.S. coast will see population grow from 123 million people to nearly 134 million people by 2020, putting more of the population at increased risk from extreme coastal storms like Sandy and Isaac, which severely damaged infrastructure and property last year. The projection comes from a new report released today from NOAA with input from the U.S. Census Bureau. According to the report, which analyzed data from the 2010 census, 39 percent of the U.S. population is concentrated in counties directly on the shoreline — less than 10 percent of the total U.S. land area excluding Alaska, and that 52 percent of the total population lives in counties that drain to coastal watersheds, less than 20 percent of U.S. land area, excluding Alaska. A coastal watershed is an area in which water, sediments, and dissolved material drain to a common coastal outlet, like a bay or the ocean.”
