Greater Buenos Aires

Not to be confused with the Autonomous City of Buenos Aires, the core city of Greater Buenos Aires.

Greater Buenos Aires (Spanish: Gran Buenos Aires, GBA), also known as the Buenos Aires Metropolitan Area (Spanish: Área Metropolitana de Buenos Aires, AMBA),^[3] refers to the urban agglomeration comprising the Autonomous City of Buenos Aires and the adjacent 24 partidos (districts) in the Province of Buenos Aires. Thus, it does not constitute a single administrative unit. The conurbation spreads south, west and north of Buenos Aires city. To the east, the River Plate serves as a natural boundary.

The term is also related to other expressions that are not necessarily well defined: the "Buenos Aires conurbation" (Conurbano Bonaerense); the "Greater Buenos Aires Agglomeration" (Aglomerado Gran Buenos Aires); and the "Metropolitan Area of Buenos Aires" (Área Metropolitana Buenos Aires, AMBA).

Colloquially, Argentines refer to the Conurbano Bonaerense as the set of 30 counties that surround the City of Buenos Aires and which are mostly populated by working-class or middle-class communities.

History

The term Gran Buenos Aires ("Greater Buenos Aires") was first officially used in 1948, when Domingo Mercante, the Governor of Buenos Aires Province, signed a bill delineating as such an area covering 14 municipalities surrounding the City of Buenos Aires.^[4]

Urban sprawl, especially between 1945 and 1980, created a vast metropolitan area of over 3,800 km² (1,500 mi²)^[5] – or 19 times the area of Buenos Aires proper. The 24 suburban partidos (counties) grew more than sixfold in population between the 1947 and 2022 censuses – or nearly 2.5% annually, compared to 1.4% for the nation as a whole.^[1][6]

While annual growth for the suburban area slowed to 0.8% between 2010 and 2022, the 12 million inhabitants in the entire 30-county area - plus the City of Buenos Aires (3 million) - account for a third of the total population of Argentina and generate nearly half (48%) of the country's GDP.^[5]

As urbanization progressed and the metro area grew in both area and density, six additional partially urbanized partidos (totaling 1,062,991 population as of the 2022 census)^[1] were added to the metropolitan area in 2006 by Law 13473 - which also adds neighboring Greater La Plata's 938,287 to the total.^[7]

There are three main groups within the Buenos Aires conurbation. The first two groups (24 partidos) comprise the traditional conurbation - or the "conurbation proper" - while the third group of six partidos is in the process of becoming fully integrated with the rest.

• Ituzaingó
• José C. Paz
• Lanús
• Lomas de Zamora

• General Rodríguez (143,211)
• Marcos Paz (67,154)
• Pilar (395,072)
