Municipalities of Mexico CityMexico City as a territorial and administrative unit is, alongside the 31 states of Mexico, one of the 32 federal entities of which Mexico consists. This entity was until 2016 the "Federal District" (), but since then, the entity has simply been known as "Mexico City" ().
Despite the Mexico City federal entity containing the word "City", it is not governed as a city but as a unit consisting of multiple municipalities; it contains both urban and rural areas, while much of the "city" (i.e., the contiguous urban area of Greater Mexico City) lies in another federal entity, the State of Mexico.
Mexico City is divided into sixteen municipalities. In Spanish, they are, as territorial units, called demarcaciones territoriales, but as units of government, they are called alcaldías (lit. "area under control of a mayor (alcalde)"); these replaced the former "boroughs" (), and the powers of local government increased..
Since 2000, residents of each borough/municipality have elected by plurality a "head of government" (), which since 2016 is referred to as the "mayor" (Spanish: alcalde).
Municipalities are subdivided into neighborhoods (colonias in Spanish) and in some parts of southern Mexico City, also into towns and rural areas.
