Depending on the definition, the region from 11.5 to 13 million inhabitants. This makes it one of the largest metropolitan areas of Latin America (currently rank 4 behind Mexico City, São Paulo and Rio de Janeiro about the same size ). Closing the extended catchment area a, the Gran Buenos Aires comes in 3rd place before the metropolitan area of Rio de Janeiro. About 30% of the country's population live in this metropolitan area.

Despite the high population and population density of the region is plagued unlike other mega-cities not of overpopulation and related infrastructure problems, as their population increases only slowly and overall tends to deconcentration and sprawl, partly also to the urban flight. Negative result of this development, however, is a very high consumption of landscape and the rapid urbanization of fertile, previously unused by agriculture areas. Which attempts to counteract by increased investment by green areas and nature reserves.

The Gran Buenos Aires is divided into the zones Norte Sur Oeste and depending on the position of the partidos. The metropolitan area of ​​Buenos Aires remains on the sidelines.

Zona Norte

Referred to as Zona Norte area occupies the north-west of the conurbation. It has 1,412,947 inhabitants, around 1.56% per decade increase in the average (mean 1991-2001 ).

The area is considered the most prosperous of the conurbation. In particular, the Partido of San Isidro, the city is also one of the oldest suburbs of Buenos Aires, has a variety of residential areas, some of them designed as gated communities. Paradoxically, there is also the largest slums of the metropolitan area, known as Villa La Cava (approx. 20,000 inhabitants) in the Partido.

The Partidos Tigre and San Fernando are popular recreation areas; in them lie the islands of the delta front of the Río Paraná. The opened in 1996 tourist Tren de la Costa runs from the affluent middle class neighborhood Olivos, where there is also the residence of the President ( quinta presidencial ) is, on the Río de la Plata along through the whole territory.
