Greater Buenos Aires (Spanish: Gran Buenos Aires, GBA), also known as the Buenos Aires Metropolitan Area (Spanish: Área Metropolitana de Buenos Aires, AMBA), 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.
Urban sprawl, especially between 1945 and 1980, created a vast metropolitan area of over 3,800 km² (1,500 mi²) – 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.
While annual growth for the suburban area slowed to 0.8% between 2010 and 2022, the 14 million inhabitants in the entire 30-county area plus the City of Buenos Aires account for a third of the total population of Argentina and generate nearly half (48%) of the country's GDP.
