Modern definitions

A megalopolis and its synonym megaregion, following the work of Gottmann, refer to two or more roughly adjacent

s that, through commonality of systems—e.g., of transport, economy, resources, and ecologies—experience a blurring of the boundaries between the population centers, such that while some degree of separation may remain, their perception as a continuous urban area is of value, e.g., "to coordinate policy at this expanded scale". Simply put, a megalopolis (or a megaregion) is a clustered network of big cities. Gottmann defined its population as 25 million, while Doxiadis defined a small megalopolis a similar cluster with a population of about 10 million. America 2050, a program of the Regional Plan Association (RPA), lists 11 megaregions in the United States and

. 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'', a term coined by Davide Gadren and Stefan Berteau. In Brazil, the term has a legal meaning, different from the English word ''megaregion'':
