BosWash

BosWash is a name coined by futurist Herman Kahn in a 1967 essay describing a theoretical United States megalopolis extending from the metropolitan area of Boston to that of Washington, D.C. The publication coined terms like BosWash, referring to predicted accretions of the Northeast, and SanSan for the urbanized region in Coastal California. The general concept for the area described by BosWash was first identified as "The Atlantic seaboard area from north of Boston to south of Washington" by French geographer Jean Gottmann in the annual report of the Twentieth Century Fund on May 25, 1958. Gottman elaborated on the 600 miles (970 km) stretch of cities in his 1961 book Megalopolis: The Urbanized Northeastern Seaboard of the United States, although the term BosWash did not appear in the work.
