Mexico City (in Spanish: Ciudad de México, México, D.F., México or simply Méjico) is the capital city of Mexico. It is the most important economic, industrial and cultural center in the country, and the most populous city with 8,720,916 inhabitants in 2005. Greater Mexico City (Zona Metropolitana del Valle de México) incorporates 58 adjacent municipalities of Mexico State and 1 municipality of the state of Hidalgo, according to the most recent definition agreed upon by the federal and state governments. As of 2008 Greater Mexico City has a population of 23 million people, making it the largest metropolitan area in the western hemisphere and the second largest in the world by population. Mexico City alone would be the 30th largest economy in the world with a higher GDP than countries like Sweden or Switzerland. Mexico City is also one of the largest financial and commercial hubs in Latin America (it should be remembered that Carlos Slim, who has been ranked, in the last few months, as either the richest or the second richest person in the world, was born and has always lived in Mexico City). The Mexican stock exchange (Bolsa Mexicana de Valores) and the country's largest banks and insurers, as well as many international financial services conglomerates for Latin America, are headquartered in the city.
