Politics -- Elections and government
In 2012 , elections were held for the post of head of government and the representatives of the Legislative Assembly . Heads of government are elected for a six-year period without the possibility of re-election . Traditionally , the position has been considered as the second most important executive office in the country . [ 93 ] The Legislative Assembly of Mexico City is formed , as it is the case for state legislatures in Mexico , by both single-seat and proportional seats , making it a system of parallel voting . Mexico City is divided into 40 electoral constituencies of similar population which elect one representative by the plurality voting system , locally called `` uninominal deputies '' . Mexico City , as a whole , is a single constituency for the parallel election of 26 representatives , elected by proportional representation , with open-party lists , locally called `` plurinominal deputies '' . Even though proportionality is supposed to prevent a party from being overrepresented , several restrictions apply in the assignation of the seats . No party can have more than 63% of all seats , both uninominal and plurinominal . In the 2006 elections , the PRD got the absolute majority in the direct uninominal elections , securing 34 of the 40 FPP seats . As such , the PRD was not assigned any plurinominal seat to comply with the law that prevents over-representation . The overall composition of the Legislative Assembly is :
Mexico City, or the City of Mexico (Spanish: Ciudad de México, American Spanish: [sjuˈða(ð) ðe ˈmexiko] (listen); abbreviated as CDMX, Nahuatl languages: Āltepētl Mēxihco), is one of the 32 states which make up the 32 Federal Entities of Mexico and the capital of Mexico and the most populous city in North America. It is one of the most important cultural and financial centres in the world. It is located in the Valley of Mexico (Valle de México), a large valley in the high plateaus in the center of Mexico, at an altitude of 2,240 meters (7,350 ft). The city has 16 alcaldías, formerly known as boroughs. The 2009 population for the city proper was approximately 8.84 million people, with a land area of 1,485 square kilometers (573 sq mi). According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21.3 million, which makes it the second largest metropolitan area of the Western Hemisphere, the eleventh-largest agglomeration (2017), and the largest Spanish-speaking city in the world. Greater Mexico City has a GDP of $411 billion in 2011, making Greater Mexico City one of the most productive urban areas in the world. The city was responsible for generating 15.8% of Mexico's GDP, and the metropolitan area accounted for about 22% of total national GDP. If it were an independent country, in 2013, Mexico City would be the fifth-largest economy in Latin America, five times as large as Costa Rica and about the same size as Peru. Mexico's capital is both the oldest capital city in the Americas and one of two founded by indigenous people, the other being Quito, Ecuador. The city was originally built on an island of Lake Texcoco by the Aztecs in 1325 as Tenochtitlan, which was almost completely destroyed in the 1521 siege of Tenochtitlan and subsequently redesigned and rebuilt in accordance with the Spanish urban standards. In 1524, the municipality of Mexico City was established, known as México Tenochtitlán, and as of 1585, it was officially known as Ciudad de México (Mexico City).
