Metropolitan areas o Mexico

**Metropolitan auries in Mexico** hae been tradeetionally defined as the group o municipalities that hivily interact wi ilk ither, uisually aroond a core ceety. In 2004, a joint effort atween CONAPO, INEGI an the Meenistry o Social Development (SEDESOL) greeit tae define metropolitan auries as ane o the follaein:
*  the group o twa or mair municipalities, in which a ceety wi a population o at least 50,000 is locatit whose urban aurie extends ower the limit o the municipality that oreeginally contained the core ceety incorporatin either physically or, unner its aurie o direct influence, ither adjacent predominantly urban municipalities, aw o which either hae a heich degree o social an economic integration or are relevant for urban politics an admeenistration; or
* a single municipality, in which a ceety o a population o at least ane million is locatit an fully contained (that is, it does no transcend the limits o a single municipality); or
* a ceety wi a population o at least 250,000 that forms a conurbation wi ither ceeties in the Unitit States.

Housomeivver, northwastren an sootheastren states are dividit intae a sma nummer o lairge municipalities whareas central states are dividit intae a lairge nummer o smawer municipalities. As such, metropolitan auries in the northwast uisually dae no extend ower mair nor ane municipality (an figurs uisually report population for the entire municipality) whareas metropolitan auries in the center extend ower mony municipalities.

A few metropolitan auries extend ayont the limits o ane state: Greater Mexico Ceety (Federal Destrict, Mexico an Hidalgo), Puebla-Tlaxcala (Puebla an Tlaxcala, but excludes the ceety o Tlaxcala), Comarca Lagunera (Coahuila an Durango), an Tampico (Tamaulipas an Veracruz).

## Leet o metropolitan auries in Mexico bi population

Thare is a total o fifty-sax **[[metropolitan aurie]]s o Mexico** as defined by the following government bodies:
* The National Institute of Statistics and Geography (INEGI).
* The Secretariat o Social Development (SEDESOL).
* The Naitional Population Cooncil (CONAPO).

## Transnational conurbations

The Unitit States shares a 2,000-mile (3,000&nbsp;km) border wi Mexico. The 2,000 mile is the maist frequently crossed internaitional border in the warld, wi aboot 250 million legal crossin ivery year. The distribution o population an urban population in Mexico haes been chyngit significantly bi the economic interaction atween dounsets in its north an the Unitit States (U.S.). The increasin population concentration in the north o Mexico is strangly associatit wi the development o the maquila industries thare an the eventual economic effects o North American Free Trade Agreement (NAFTA). Metropolitan auries locatit at the border wi the U.S. form transnaitional conurbations wi deep economic an demografic interaction. For example, the San Dieg-Tijuana metropolitan aurie consists o San Diego Coonty in the U.S. an the municipalities o Tijuana, Playas de Rosarito, an Tecate in Mexico. The total population o the region haes been estimatit tae be juist ower 5 million in 2009, makkin it bi far the lairgest bi-naitional metropolitan aurie shared atween the U.S. an Mexico. The Naitional Population Cooncil (CONAPO) recognises the existence o such metropolitan auries and defines them as the municipalities that contain a ceety o at least 200,000 inhabitants which share processes o conurbation wi ceeties o the U.S.

## Megalopolis o central Mexico

A megalopolis is defined as a lang chain o continuous metropolitan auries, or territories that are relatively integratit amangst ilk ither, a clear example o which is the Northeast Megalopolis in the Unitit States. In 1996, the *Programa General de Desarollo Urbano del Distrito Federal* first proposed this concept tae refer tae the megalopolis o central Mexico, which wis later expandit bi PROAIRE, a metropolitan commission on the environment. A megalopolis, is kent in Spainyie as a *corona regional de ciudades* ("regional ring o ceeties"). The Megalopolis o central Mexico wis defined tae be integratit bi the metropolitan auries o Mexico Ceety, Puebla, Cuernavaca, Toluca an Pachuca, which mey conform complex subregional rings thairsels an aw (i.e. Greater Puebla conformin a regional ring wi Atlixco, San Martín Texmelucan, Tlaxcala an Apizaco). The megalopolis o central Mexico is integratit bi 173 municipalities (91 o the state o Mexico, 29 o the state o Puebla, 37 o the state o Tlaxcala, 16 o Morelos an 16 o Hidalgo) an the 16 burghs o the Federal Destrict, wi an approximate total population o amaist 25 million fowk.
