The history of the real estate development of Long Island followed the classical mode from inner city to the suburban areas of Nassau and Suffolk Counties. The greatest development occurred shortly after World War II. In 1970, the census count for Suffolk County was over the one million mark. It appeared that there would be no end to this wave of development and that Suffolk County was destined for the same fate that befell Nassau County. Nassau County, at the end of World War II, contained many viable working farms growing food crops and producing dairy products for New York City. By 1970, the farms of Nassau County were gone, covered over by urban sprawl.
