The 'BosWash' (also referred to as 'Bosnywash', 'Boshington', the '
Northeast Corridor', the 'BosWash Corridor', or simply the 'Northeast
megalopolis') is the name for a group of
metropolitan areas in the
northeastern United States, extending from
Boston,
Massachusetts, to
Washington, D.C., including
Providence,
Rhode Island;
Hartford,
New Haven and
Stamford,
Connecticut;
New York City,
New York;
Newark,
New Jersey;
Philadelphia,
Pennsylvania;
Wilmington,
Delaware; and
Baltimore,
Maryland. The geographic trend was first identified in
French geographer Jean Gottmann's book ''Megalopolis: The Urbanized Northeastern Seaboard of the United States'' (1961). The cities are also linked economically, and by transportation and communications.

Population-density map of BosWash
According to Gottmann, BosWash "provides the whole of America with so many essential services, of the sort a community used to obtain in its 'downtown' section, that it may well deserve the nickname of
Main Street of the nation." He also identified two other megalopolises in the U.S.,
ChiPitts and
SanSan, but these terms did not achieve wide use.
Extent
BosWash extends from extreme southern
Maine and
New Hampshire south to
Northern Virginia, which includes a large portion of suburban Washington DC, including
Alexandria and
Arlington. It has a reported population of 44 million, or 16 percent of the population of the United States (about 0.7 percent of the world population), three
World Cities (
New York,
Washington, and
Boston), and four of the
world's 70 largest metropolitan areas (New York, Boston,
Philadelphia, and
Baltimore-Washington).
The region is home to the
New York Stock Exchange and
NASDAQ, the
White House and
United States Capitol, the
UN Headquarters, the headquarters of
ABC,
NBC,
CBS,
FOX and the
New York Times Company as well as the ''
Washington Post'', and six of the eight
Ivy League Universities. The headquarters of many major financial companies such as
State Street,
Citigroup, and
Fidelity are located within the region. The region accounts for 1/5 of the economic activity in the US and it is home to 58 of the
Fortune Global 500 companies.
Amtrak's fastest train, the
Acela Express, runs on the
Northeast Corridor, an
electrified rail line extending the length of the BosWash area.
Interstate 95, one of the most vital highways in the country, is also a major transportation route for the BosWash area.
The major cities in the BosWash megalopolis include the following (listed north to south):

Several small and medium-sized metropolitan areas near the southwestern end of the corridor, including
Lancaster,
Harrisburg, and
York, Pennsylvania and
Hagerstown and
Frederick, Maryland, are also sometimes considered part of the region, though opinions vary from geographer to geographer as to which cities are included or excluded.
