A metropolitan area in Mexico is defined as a group of municipalities that heavily interact with each other, usually around a core city.<ref name="CONAPO">[http://www.inegi.gob.mx/est/contenidos/espanol/metodologias/otras/zonas_met.pdf CONAPO Áreas Metropolitanas] {{webarchive|url=https://web.archive.org/web/20110501065908/http://www.inegi.gob.mx/est/contenidos/espanol/metodologias/otras/zonas_met.pdf |date=May 1, 2011 }}</ref> In 2004, a joint effort between CONAPO, [[Instituto Nacional de Estadística y Geografía|INEGI]] and the Ministry of Social Development (SEDESOL) agreed to define metropolitan areas as either:<ref name="CONAPO"/>
* a group of two or 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.

In 2020 there were 48 metropolitan areas in Mexico, in which close to 53% of the country's population lives.<ref name=metro>[https://www.gob.mx/sedatu/documentos/metropolis-de-mexico-2020%3Fstate%3Dpublished "Metropolis de México 2020"] Retrieved September 7, 2024.</ref> The most populous metropolitan area in Mexico is the ''Metropolitan Area of the Valley of Mexico'', or [[Greater Mexico City]], which in 2020 had a population of 21.8&nbsp;million, or around 18% of the nation's population. The next four largest metropolitan areas in Mexico are [[Monterrey Metropolitan area|Greater Monterrey]] (5.3&nbsp;million), [[Guadalajara Metropolitan Area|Greater Guadalajara]] (5.2&nbsp;million), [[Metropolitan area of Puebla|Greater Puebla]] (3.2&nbsp;million) and [[Greater Toluca]] (2.3&nbsp;million),<ref name="census2020" /> whose added population, along with Greater Mexico City, is equivalent to nearly 30% of the nation's population. Greater Mexico City was the fastest growing metropolitan area in the country since the 1930s until the late 1980s. Since then, the country has slowly become economically and demographically less centralized. From 2000 to 2005 the average annual growth rate of Greater Mexico City was the lowest of the five largest metropolitan areas, whereas the fastest growing metropolitan area was Puebla (2.0%) followed by Monterrey (1.9%), Toluca (1.8%) and Guadalajara (1.8%).<ref name="sintesis">{{cite web|url=http://www.inegi.gob.mx/img/ppt.gif|title=Síntesis de resultados 2005|website=Inegi.org.mx|access-date=August 29, 2017|archive-date=March 3, 2016|archive-url=https://web.archive.org/web/20160303215818/http://www.inegi.gob.mx/img/ppt.gif|url-status=live}}</ref>
