Buenos Aires, autonomous city and capital of Argentina, is composed of forty-eight neighbourhoods (locally known as barrios). The city is also legally divided into communes, each one including one or more barrios. Among the most visited and populated barrios are Palermo, Recoleta, Puerto Madero, Belgrano, San Telmo, La Boca, Monserrat and Caballito. Sectors of the city are also traditionally known as neighborhoods by the inhabitants of Buenos Aires, but not officially by the authorities of the city; some examples include Chinatown, Barrio Norte and the Microcentro.
In alphabetical order, with the corresponding population and the commune they are grouped in.
The name Barrio Norte refers to the area around Avenida Santa Fe, encompassing parts of Retiro, Recoleta, and Palermo.
The name Barrio Sur was used in the past to encompass the southern neighborhoods. This name has mostly fallen out of use, but survives in the lyrics of the tango Sur, which refer to specific places in Nueva Pompeya and Boedo, and in the short story "The South" by Jorge Luis Borges, where the conventional wisdom is recalled that "the South begins when crossing Rivadavia Avenue".
