A megalopolis ( sometimes called a megapolis ; also megaregion, or supercity ) is typically defined as a chain of roughly adjacent metropolitan areas, which may be somewhat separated or may merge into a continuous urban region. Emerging megalopolises in the developing world include the Pearl River Delta, which when formed will constitute the core part of a Southern China Coast megaregion ; the Unified Jakarta - Bandung metro area forming the core of the Northern Java megaregion ; and the Yangtze River Delta core, a part of a Central Chinese Coast megaregion.

Later, it was used by Jean Gottmann in his landmark 1961 study, Megalopolis : The Urbanized Northeastern Seaboard of the United States, to describe the chain of metropolitan areas along the northeastern seaboard of the U.S. extending from Boston, Massachusetts, through New York City, Philadelphia, Baltimore, and ending in Washington, D.C. and Northern Virginia. The latter is sometimes called the `` BosWash megalopolis ''. Definitions Northeast megalopolis ( United States ) and Taiheiyō Belt ( Japan ). Megalopolis is a Western deformation of the Greek word that derived from Greek : μέγας ( mégas ) meaning ' great ' and Greek : πόλις ( pólis ) meaning ' city ', therefore literally a ' great city '. This term is closer in meaning to megacity. Because in Greek, πόλις is feminine, the correct term is megalopolis. The Ancient Greek city of Megalopolis was formed by the Arcadian League by bringing together smaller communities. A megalopolis, also known as a megaregion, is a clustered network of cities. Gottmann defined its population as 25 million. Doxiadis defined a small megalopolis a similar cluster with a population of about 10 million. America 2050, a program of the Regional Plan Association, lists 11 megaregions in the United States and Canada. Literally, megalopolis in Greek means a city of exaggerated size where the prefix megalo - represents a quantity of exaggerated size. Megapolitan areas were explored in a July 2005 report by Robert E. Lang and Dawn Dhavale of the Metropolitan Institute at Virginia Tech. A later 2007 article by Lang and Nelson uses 20 megapolitan areas grouped into 10 megaregions. The concept is based on the original Megalopolis model. 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. In Brazil, the similar sounding terms to megaregion ( megarregião when translated to English, are actually legally distinct and take on quite different meaning : Mesoregions of Brazil ( mesorregião ) and Microregions of Brazil ( microrregião ). Africa Cairo -- Giza -- Qalyubia -- Helwan -- 6th of October City ( Greater Cairo ), Egypt ( 16 million ) The area around the Nile is also very densely populated. Nile River Delta Governorates ( Alexandria, Beheira, Kafr el - Sheikh, Gharbia, Monufia, Qalyubia, Dakahlia, Damietta, Al Sharqia, and Port Said ) have a combined population of 41,045,135. The total area of these Governorates is 18,199 square miles making the population density 2,255.4 per square mile.
