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 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.
