Levittown, New York, an unincorporated residential community in Nassau County. It is on Long Island, 27 miles (43 km) east of New York City. Levittown was built by Levitt & Sons, on 4,200 acres (1,700 hectares) of farmland, as a planned community with churches, schools, and recreational facilities. The houses were mass-produced and are much alike in appearance. Construction began in 1946 and ended in 1951.

About 90 per cent of Levittown's original occupants were veterans and their families. The community was inspired by the post-World War II need for veterans' housing and the availability of government-insured mortgages.

Population: 53,067.
