The cityball is located on the western shore of the estuary of the Río de la Plata, on the South American continent's southeastern coast. "Buenos Aires" can be translated as "fair winds" or "good airs", but the former was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Señora Santa María del Buen Ayre", named after the Madonna of Bonaria in Sardinia. The Greater Buenos Aires conurbation, which also includes several Buenos Aires Provinceball districts, constitutes the fourth-most populous metropolitan area in the Americas, with a population of around 15.6 million.
The cityball of Buenos Airesball is neither part of Buenos Aires Provinceball nor the Provinceball's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Airesball was federalized and removed from Buenos Aires Provinceball. The cityball limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the cityball. The 1994 constitutional amendment granted the city autonomy, hence its formal name of Autonomous City of Buenos Airesball (Ciudad Autónoma de Buenos Aires; "CABA"). Its citizens first elected a chief of government (i.e. mayor) in 1996; previously, the mayor was directly appointed by the President of the Republic.
Buenos Airesball's quality of life was ranked 91st in the world in 2018, being one of the best in Latin America. In 2012, it was the most visited cityball in South America, and the second-most visited cityball in Latin America (behind Mexico Cityball).
Buenos Airesball is known for its preserved Eclectic European architecture and rich cultural life. Buenos Airesball held the 1st Pan American Games in 1951 as well as hosting two venues in the 1978 FIFA World Cup. It also hosted the 2018 Summer Youth Olympics and the 2018 G20 summit.
Buenos Airesball is a multicultural cityball, being home to multiple ethnic and religious groups. Several languages are spoken in the cityball in addition to Spanish, contributing to its culture and the dialect spoken in the cityball and in some other parts of the countryball. This is because in the last 151 years, the cityball, and the countryball in general, has been a major recipient of millions of immigrants from all over the world, making it a melting pot where several ethnic groups live together and being considered one of the most diverse cityballs of the Americas.
