Mexico City megalopolis

The Mexico City megalopolis, also known as the Megalopolis of Central Mexico (Corona regional del centro de México), is a megalopolis containing Greater Mexico City and surrounding metropolitan areas.

In 1996, the Programa General de Desarollo Urbano del Distrito Federal first proposed the concept of a "Megalopolis of Central Mexico", which was later expanded by PROAIRE, a metropolitan commission on the environment.

The Megalopolis of Central Mexico (pre-2019 definition) includes 10 metropolitan areas of Mexico, as defined by the National Population Council (CONAPO): Valley of Mexico, Puebla, Toluca, Queretaro, Cuernavaca, Pachuca, Tlaxcala–Apizaco, Cuautla, Tulancingo, Tula and Tianguistenco. Some of these areas form complex subregional rings themselves (i.e. Puebla forming a regional ring with Atlixco, San Martín Texmelucan, Tlaxcala and Apizaco).

The megalopolis (pre-2019 definition) spreads over 19500 km2, and consists of 185 subdivisions in 6 federative entities: 169 municipalities, 81 in the State of Mexico, 39 in Tlaxcala, 19 in Puebla, 16 in Hidalgo, and 14 in Morelos; plus the 16 boroughs of Mexico City. Its population as of 2020 is 30.8 million people, about 25% of the country's total.

Since 2019 the megalopolis (as defined by the Environmental Commission for the Megalopolis, CAMe) includes the state of Querétaro. The Querétaro metropolitan area is also part of the fast-growing macroregion of Bajío.
