Mexico City megalopolis
The Mexico City megalopolis, also known as the Megalopolis of Central Mexico (Spanish: 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.
