Greater Buenos Aires (Spanish:Gran Buenos Aires,GBA), also known as theBuenos Aires Metropolitan Area (Spanish:Área Metropolitana de Buenos Aires,AMBA),[3] refers to theurban agglomeration comprising theAutonomous City of Buenos Aires (CABA), and the adjacent 24partidos (counties) in theProvince of Buenos Aires (together known as "Conurbano"). Thus, it does not constitute a single administrative unit. Theconurbation spreads south, west and north of Buenos Aires city. To the east, theRiver 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 theConurbano 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.
The termGran Buenos Aires ("Greater Buenos Aires") was first officially used in 1948, whenDomingo Mercante, theGovernor 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 suburbanpartidos (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 totalpopulation 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 urbanizedpartidos (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 neighboringGreater La Plata's 938,287 to the total.[7]
TheNational Institute of Statistics and Censuses (INDEC) has defined Greater Buenos Aires.[8]
There are three main groups within the Buenos Aires conurbation. The first two groups (24partidos) comprise the traditional conurbation - or the "conurbation proper" - while the third group of sixpartidos is in the process of becoming fully integrated with the rest.
The six additional partially urbanizedpartidos added to the metropolitan area in 2006 by Law 13473 (which also addsGreater La Plata's 938,287 to the total) are:[7]
The 2022 Census later included, for statistical purposes, these six outlyingpartidos (totaling 497,700):[9]
