"Neigborhoods:
In general, colonias are a recurrent feature in Mexican cities and larger towns. They are the basic geographical unit in Mexico city and in contrast to the delegaciones (the boroughs of the Mexican Federal District) they are always included in a persons address. However colonias do not have any administrative attributions, and as with most of the city's organization, there is no standard for the size, population or basic infrastructure to qualify as a colonia. To complicate things further, Mexico City inhabitants may sometimes call a colonia what is actually a collection of official colonias.

Apparently the name, which literally means colony, arose in the late 19th, early 20th century, when one of the first urban developments outside the city's core was inhabited by a French colony in the city. Some notable colonias are:

Centro - Covers the historic downtown of Mexico City (centro histórico).
Condesa - Artistic district notable by its Art Deco architecture.
Roma - Beaux Arts neighbourhood next to Condesa, one of the oldest in Mexico City.
Del Carmen - Historic, countercultural neighborhood in downtown Coyoacán.
del Valle - Cradle of many important people in México history like José López Portillo
Las Lomas - Upscale residential neighbourhood.
Nápoles - Next to colonia del Valle, on both sides of Insurgentes avenue.
San Ángel - Historic residential and shopping area.
Santa Fe - Financial and business district.
Jardines del Pedregal Upscale residential neighborhood next to UNAM.
Polanco - Shopping, business and tourist area.
Tepito - Popular flea market.
Tlatelolco - Site of the Plaza de las Tres Culturas and the Tlatelolco massacre. High-density residential neighborhood.
Zona Rosa - Shopping district and tourist area."
