Premise: The Northeast megalopolis ( also Boston -- Washington Corridor or Bos-Wash Corridor ) is the most heavily urbanized region of the United States , running primarily northeast to southwest from the northern suburbs of Boston , Massachusetts , to the southern suburbs of Washington , D.C. , in Northern Virginia . It includes the major cities of Boston , Providence , Hartford , New York City , Philadelphia , Baltimore , and Washington , D.C. , along with their metropolitan areas and suburbs as well as many smaller urban centers . French geographer Jean Gottmann popularized the term in his landmark 1961 study of the region , Megalopolis : The Urbanized Northeastern Seaboard of the United States . Gottmann concluded that the region 's cities , while discrete and independent , are uniquely tied to each other through the intermeshing of their suburban zones , taking on some characteristics of a single , massive city : a megalopolis .
Hypothesis: There are zero cities in the Northeast megalopolis.
