Metropolitan areas of Mexico
From Wikipedia, the free encyclopedia
Metropolitan areas in Mexico have been traditionally defined as the group of municipalities that heavily interact with each other, usually around a core city.[1] In 2004, a joint effort between CONAPO, INEGI and the Ministry of Social Development (SEDESOL) agreed to define metropolitan areas as either:[1]
- the group of two ore more municipalities in which a city with a population of at least 50,000 is located whose urban area extends over the limit of the municipality that originally contained the core city incorporating either physically or under its area of direct influence other adjacent predominantly urban municipalities all of which have a high degree of social and economic integration or are relevant for urban politics and administration; or
- a single municipality in which a city of a population of at least one million is located and fully contained, (that is, it does not transcend the limits of a single municipality); or
- a city with a population of at least 250,000 which forms a conurbation with other cities in the United States of America.
It should be noted, however, that northwestern and southeastern states are divided into a small number of large municipalities whereas central states are divided into a large number of smaller municipalities. As such, metropolitan areas in the northwest usually do not extend over more than one municipality (and figures usually report population for the entire municipality) whereas metropolitan areas in the center extend over many municipalities.
Few metropolitan areas extend beyond the limits of one state, namely: Greater Mexico City (Federal District, Mexico and Hidalgo), Puebla-Tlaxcala (Puebla and Tlaxcala, but excludes the city of Tlaxcala), Comarca Lagunera (Coahuila and Durango), and Tampico (Tamaulipas and Veracruz).

[edit] Transnational conurbations
Metropolitan areas located at the border with the United States also form transnational conurbations with deep economic and demographic interaction. CONAPO also defines and recognizes the existence of such metropolitan areas and defines them as the municipalities that contain a city of at least 250,000 inhabitants which share processes of conurbation with cities of the United States of America.[1] Some transnational conurbations are:
- Tijuana-San Diego, with a joint population of 4.8 million
- Ciudad Juárez-El Paso, with a joint population of 2.3 million.
[edit] Megalopolis of central Mexico
A megalopolis is defined as a long chain of continuous metropolitan areas, or territories that are relatively integrated amongst each other, an clear example of which is BosWash in the United States. In 1996, the Programa General de Desarollo Urbano del Distrito Federal first proposed this concept to refer to the megalopolis of central Mexico, which was later expanded by PROAIRE, a metropolitan commission on the environment.[3] A megalopolis, is known in Spanish as a corona regional de ciudades ("regional ring of cities"). The Megalopolis of central Mexico was defined to be integrated by the metropolitan areas of Mexico City, Puebla, Cuernavaca, Toluca and Pachuca, which may also conform complex subregional rings themselves (i.e. Greater Puebla conforming a regional ring with Atlixco, San Martín Texmelucan, Tlaxcala and Apizaco). The megalopolis of central Mexico is integrated by 173 municipalities (91 of the state of Mexico, 29 of the state of Puebla, 37 of the state of Tlaxcala, 16 of Morelos and 16 of Hidalgo) and the 16 boroughs of the Federal District,[3] with an approximate total population of almost 25 million persons.
