Northeast Megalopolis, Taiheiyō Belt

A megalopolis (sometimes called a megapolis or megaregion) is typically defined as a chain of roughly adjacent metropolitan areas. The term was used by Lewis Mumford in his 1938 book, The Culture of Cities, which described it as the first stage in urban overdevelopment and social decline. Later, it was used by Jean Gottmann in 1957, to describe the huge metropolitan area along the eastern seaboard of the U.S. extending from Boston, Massachusetts through New York City; Philadelphia, Pennsylvania; Baltimore, Maryland and ending in Washington, D.C..

Definition

A megalopolis, also known as a megaregion, is a clustered network of cities with a population of about 10 million or more.[1][2][3] America 2050,[4] an organization sponsored by the Rockefeller and Ford Foundations, lists 11 megaregions in the United States and Canada.[1] Megapolitan areas were explored in a July 2005 report by Robert E. Lang and Dawn Dhavale of the Metropolitan Institute at Virginia Tech.[5] A later 2007 article by Lang and Nelson uses 20 megapolitan areas grouped into 10 megaregions.[6] The concept is based on the original Megalopolis model.[3]

Modern interlinked ground transportation corridors, such as rail and highway, often aid in the development of megalopolises. Using these commuter passageways to travel throughout the megalopolis is informally called megaloping. This term was coined by Davide Gadren and Stefan Berteau.[7]

Mexico

  • The Megalopolis of Central Mexico was defined to be integrated by the metropolitan areas of Mexico City, Puebla, Cuernavaca, Toluca and Pachuca. The megalopolis of central Mexico is integrated by 173 municipalities (91 of the state of Mexico, 29 of the state of Puebla, 37 of the state of Tlaxcala, 16 of Morelos and 16 of Hidalgo) and the 16 boroughs of the Federal District,[7] with an approximate total population of 35 million.
  • The “Corredor del Bajío” in Northern Central Mexico is a chain of settlements that stretches 334 km (208 mi) in four states (Querétaro, Guanajuato, Jalisco, and Aguascalientes). Federal Highway 45 works as the backbone for this megalopolis, which includes 4 metro areas (León (ranked 7th nationwide), Querétaro (11th), Aguascalientes (13th) and San Francisco del Rincón (53rd)) and 5 medium sized cities (Lagos de Moreno, Irapuato, Salamanca, Celaya, and San Juan del Río). Route 45 runs through 5 more municipalities (Encarnación de Díaz, Cortazar, Villagrán, Apaseo el Grande, and Pedro Escobedo). This system of 21 municipalities has a population of 5.141 million people and high levels of growth. However, some other cities could be included in this megalopolis (such as San Miguel de Allende and Guanajuato) since even if they are not located on Route 45 they are close enough to interact heavily with the system. It is expected that in 2040, this corridor will fuse with the megalopolis of Central Mexico.[13]

South America

Europe

  • Milan metropolitan area - Recognized by the OECD. (7,400,000 in Italy, that is more than one tenth of the national population). Potentially some parts of the Swiss Canton Ticino can be considered within the metropolis, thus making it a transnational city; this is not recognized by the OECD definition, though.
  • Attica - The megapolis of Athens, Greece, covering the most of the basin of the district of Attica. (4.5 million)

Asia

Emerging megacities in China (in decreasing order of population):

  • The central Liaoning city cluster in China. Within 150 km from its center Shenyang (7.2 million), it has Fushun (3 million), Anshan City (3.6 million), Benxi (1.5 million), Liaoyang (1.8 million), Yingkou (2.2 million), Panjin (1.2 million), and Tieling (3.4 million), with a total population of 23 million. And it can be further extended to Dalian (6.2 million), Fuxin (2 million) and Dandong (2.4 million). This area used to be the most industrialized region in China. It declined during 1980s-1990s, but in recent years, it has rapidly revived.
