Constituent urban areas of each megalopolis are based on reckoning by a single American organization, the Regional Plan Association (RPA). The RPA definition of the Great Lakes Megalopolis includes some Canadian metropolitan areas with the United States, including some but not all major urban centres in the Windsor-Quebec City Corridor. Note that one city, Houston, is listed in two different Megalopolis regions as defined by the RPA, (the Gulf Coast and the Texas Triangle). 77% of the U.S. population lives in at least one of the megalopolises listed below.[40]

The following megaregions in Colombia are expected to have nearly 93% (55 million people) of its population by 2030, up from the current 72% . There are currently four major megaregions in Colombia.

Other sources[45] show that another megaregion may be considered:

Metropolis is a 1927 German expressionist science-fiction drama film directed by Fritz Lang. Written by Thea von Harbou in collaboration with Lang,[57][58] it stars Gustav Fröhlich, Alfred Abel, Rudolf Klein-Rogge and Brigitte Helm. Erich Pommer produced it in the Babelsberg Studios for Universum Film A.G. (Ufa). The silent film is regarded as a pioneering science-fiction movie, being among the first feature-length movies of that genre.[59] Filming took place over 17 months in 1925–26 at a cost of over five million Reichsmarks.[60]

In the Judge Dredd (1977) comic book series and its spinoff series, Mega-City One is a huge fictional megalopolis-size city-state covering much of what is now the Eastern United States and some of Canada. The exact geography of the city depends on which writer and artist has done which story, but from its first appearance it has been associated with New York City's urban sprawl; originally it was presented as a future New York, which was retconned as the centre of a "Mega-City One" in the very next story.[61] The Architects' Journal placed it at No. 1 in their list of "comic book cities".[62]

Blade Runner is a 1982 neo-noir science fiction film directed by Ridley Scott, written by Hampton Fancher and David Peoples, and starring Harrison Ford, Rutger Hauer, Sean Young, and Edward James Olmos. It is a loose adaptation of Philip K. Dick's novel Do Androids Dream of Electric Sheep? (1968). The film is set in a dystopian future Los Angeles of 2019, in which synthetic humans known as replicants are bio-engineered by the powerful Tyrell Corporation to work on off-world colonies. When a fugitive group of replicants led by Roy Batty (Hauer) escapes back to Earth, burnt-out cop Rick Deckard (Ford) reluctantly agrees to hunt them down.

In William Gibson's Sprawl trilogy, "the Sprawl" is a colloquial name for the "Boston-Atlanta Metropolitan Axis" (BAMA), an urban sprawl environment on a massive scale, and a fictional extension of the real Northeast megalopolis. The Sprawl is a visualization of a future where virtually the entire East Coast of the United States, from Boston to Atlanta, has melded into a single mass of urban sprawl.[63] It has been enclosed in several geodesic domes and merged into one megacity. The city has become a separate world with its own climate, no real night/day cycle, and an artificial sky that is always grey.
