Roosevelt is a hamlet and census-designated place (CDP) in the Town of Hempstead, which is in Nassau County, New York, United States on Long Island. The population was 16,258 at the 2010 census.
The community is named for former President Theodore Roosevelt, but was also known as Greenwich and Rum Point for a time before that. While Roosevelt once had a predominantly-white population, white flight and real estate blockbusting became a major issue during the postwar housing boom in the 1950s and 1960s, when the community saw an influx of African-American residents.
Notable residents of the community have included both Flava Flav and Chuck D. of Public Enemy, actors Eddie and Charlie Murphy, basketball player Dr. J (Julius Erving), singers Aaron and Damian Hall and radio host Howard Stern. In addition, Melvyn M. Sobel, James V. Petrungaro and David D. Weinberg, the original three members of The Ravens, a rock group well known on Long Island, performed from 1965–1969.
According to the 2010 census, the population of Roosevelt is 16,272. The median household income is listed as $68,625.
According to the United States Census Bureau, the CDP has a total area of 1.8 square miles (4.6 km2). 1.8 square miles (4.6 km2) of it is land and 0.56% is water.
As of the census of 2000, there were 15,854 people, 4,061 households, and 3,362 families residing in the CDP. The population density was 3,438.9/km2 (8,916.8/mi2).
