Mexico City is divided into 16 boroughs, officially designated as demarcaciones territoriales or colloquially known as alcaldías[citation needed] in Spanish. Headed by a mayor, these boroughs kept the same territory and name as the former[when?] delegaciones while expanding their local government powers.[1] Boroughs are considered third-level subdivisions for statistical data collection and cross-country comparisons. The traditional center of Mexico City comprises four boroughs: Benito Juárez, Cuauhtémoc, Miguel Hidalgo, and Venustiano Carranza.

Mexico City is one of the 32 federal entities of Mexico, with the others being the 31 states. It was named Distrito Federal (Federal District) until February 5, 2016, when it was officially renamed the Ciudad de México.[2] According to the 2020 Mexican census, it is the second most populated entity with 9,209,944 inhabitants and the smallest by land area, spanning 1,494.3 square kilometres (577.0 sq mi).[3][4]

Despite containing the word "city", it is not governed as a city but as a unit consisting of multiple subdivisions. As a result of the political reforms enacted in 2016, it is no longer designated as a federal district and became a city, a member entity of the Mexican federation, the seat of the Powers of the Union, and the capital of Mexico.[1] Thus, Mexico City is not organized into municipalities.

The largest borough by population is Iztapalapa, with 1,835,486 residents, while the smallest is Milpa Alta, with 152,685 residents. Iztacalco is the most densely populated subdivision in Mexico.[3] The largest borough by land area is Tlalpan, which spans 314.50 km2 (121.43 sq mi), and the smallest is Iztacalco, with 23.10 km2 (8.92 sq mi).[4]

The most recent boroughs are Benito Juárez, Cuauhtémoc, Miguel Hidalgo, and Venustiano Carranza, all established in 1970 out of the former circumscription of Mexico City.[5]
