Levittown is a census-designated place (CDP) and planned community in Bucks County, Pennsylvania, United States, within the Philadelphia metropolitan area. The population was 52,983 at the 2010 census. It is 40 feet (12 m) above sea level. Though not a municipality, it is sometimes recognized as the largest suburb of Philadelphia in Pennsylvania (while Upper Darby Township, Lower Merion Township, Bensalem Township, Abington Township and Bristol Township are municipalities larger in size in the three surrounding Pennsylvania counties). Starting with land purchased in 1951, it was planned and built by Levitt & Sons. The brothers Bill Levitt and architect Alfred Levitt designed its six typical houses.
The majority of the land on which it is built was purchased in 1951. Levitt and Sons only built six models of houses in Levittown, all single-family dwellings with lawns: the Levittowner, the Rancher, the Jubilee, the Pennsylvanian, the Colonial and the Country Clubber, with only modest exterior variations within each model. The homes were moderately priced and required only a low down payment. Construction of Levittown began in February 1952, soon after completion of Levittown, New York, located on Long Island.
