Metropolitan areas of Mexico explained

Metropolitan areas of Mexico have been traditionally defined as the group of municipalities that heavily interact with each other, usually around a core city, in Mexico. The phenomenon of metropolization in Mexico is relatively recent, starting in the 1940s.[1] Because of an accelerated level of urbanization in the country, the definition of a metropolitan area (in Mexican Spanish: zona metropolitana) is reviewed periodically by the Mexican population and census authorities.

Identifying metropolitan areas in Mexico

One of the first studies on a methodology to define and quantify the metropolitan areas in Mexico was published by El Colegio de México in 1978. In Luis Unikel's book "Urban Development in Mexico: Diagnosis and Future Implications", a metropolitan area was designated as "the territorial area that includes the political and administrative units from a central city, and any contiguous, urban political and administrative units with a direct socioeconomic interrelation with the central city, and viceversa". 12 metropolitan areas were identified, containing 25.6 percent of the national population.[2]

A 1993 study published by Mexico's National Institute of Public Administration (INAP), "Metropolitan and Regional Government and Management", defined a metropolitan area as "the physical or functional union of two or more municipalities that contain a central city and its contiguous locations, or a central city and surrounding locations under its socio-economic influence", and increased the number of metropolitan areas to 37.

In 2004, a joint effort between the National Population Council (CONAPO), INEGI and the Ministry of Social Development (SEDESOL) agreed to officially define metropolitan areas as any of the following:[3]

The number of metropolitan areas increased to 55 under these criteria.

CONAPO last reviewed the criteria in 2018, and from that date, a metropolitan area in Mexico is defined as:[4]

These new criteria also introduced two groups of municipalities within a metropolitan area: core, the location of the core city or cities in the area; and peripheral, surrounding, urban areas with high degree of integration with the core.

As per this last definition, there are currently 74 metropolitan areas in Mexico. 75.1 million people, 62.8 percent of the country population, live within a metropolitan area.

Metropolitan areas beyond municipal borders

Northern states are generally divided into a small number of large municipalities, whereas central and southern states are divided into a large number of smaller municipalities. As such, metropolitan areas in the north of the country cover fewer municipalities than those in the central and southern parts.

A few metropolitan areas extend beyond the limits of one state, like Greater Mexico City (Mexico City, Mexico and Hidalgo), La Laguna (Coahuila and Durango), and Tampico (Tamaulipas and Veracruz).

Financial situation of metropolitan areas in Mexico

Determining the public finance of metropolitan areas in Mexico has been challenging. Metropolitan areas in Mexico are complex in terms of population and industry. The Federal government of Mexico is transferring money to Municipalities of Mexico, but metropolitan areas in Mexico are increasingly plagued by a weakening fiscal capacity and rising local debt. The political factors that undermine a local tax reform in the metropolitan areas of Mexico are not well documented.[5]

Transnational conurbations

The United States shares a 2,000 mi (3,000 km) border with Mexico. It is the most frequently crossed international border in the world, with about 250 million legal crossings every year.

The distribution of the population in Mexico, especially, in urban areas, has been changed significantly by the economic interaction between settlements in its north and the United States. The increasing population concentration in the north of Mexico is strongly associated with the development of the maquila industries there and the eventual economic effects of North American Free Trade Agreement (NAFTA).[10]

Metropolitan areas at the border with the United States form transnational conurbations with deep economic and demographic interaction. For example, the San Diego – Tijuana metropolitan area consists of San Diego County in the US and the municipalities of Tijuana, Playas de Rosarito, and Tecate in Mexico. The total population of the region has been estimated to be just over 5 million in 2009, making it by far the largest binational metropolitan area shared between the US and Mexico.[11] The National Population Council (CONAPO) recognizes the existence of such metropolitan areas and defines them as the municipalities with a city of at least 200,000 inhabitants and sharing processes of conurbation with cities of the US:[3]

Mexico City megalopolis

See main article: Mexico City megalopolis. A megalopolis is defined as a long chain of continuous metropolitan areas or territories that are relatively integrated amongst each other, a clear example being the Northeast Megalopolis in the United States. In 1996, the Programa General de Desarollo Urbano del Distrito Federal first proposed this concept to refer to the Mexico City megalopolis, or "megalopolis of central Mexico", which was later expanded by PROAIRE, a metropolitan commission on the environment.[16]

Known in the Spanish language as the corona regional del centro de México (regional ring), the megalopolis of Central Mexico was defined as the consolidation of the metropolitan areas of the Valley of Mexico, Puebla, Cuernavaca, Toluca, Pachuca, Tlaxcala, Tulancingo, Tula, Cuautla and Tianguistenco.

The Mexico City megalopolis spreads over 19,500 square kilometres (7,500 sq miles) and consists of 185 subdivisions in 6 federative entities. Furthermore, The Mexico City megalopolis spreads over 169 municipalities, of which 81 are in the State of Mexico. A further 39 are in Tlaxcala, 19 are in Puebla, 16 are in Hidalgo, 14 are in Morelos, and last but not least 16 boroughs of Mexico City.[16]
