Growth began in the early 1950s, when William Levitt chose Bucks County for his second "Levittown". Levitt bought hundreds of acres of woodlands and farmland, and constructed 17,000 homes and dozens of schools, parks, libraries, and shopping centers. By the time the project ended, the population of Levittown had swelled to almost 74,000 residents. At the time, only whites could buy homes. This rule however, was soon overturned. Other planned developments included Croydon and Fairless Hills. This rapid sprawl continued until the mid-1960s.
