A megalopolis can also be defined as the coalescence that results from the independent growth of various metropolitan areas. The term was first used in the United States by Jean Gottman in 1957, to refer to the entire metropolitan area of the east coast of that country, extending from Boston, Massachusetts to the city of Washington, DC and that includes New York City and Philadelphia.
