About Ciudad de Buenos Aires

Buenos Aires, officially the Autonomous City of Buenos Aires, is the capital and largest city of Argentina. It is located on the southwest of the Río de la Plata. Buenos Aires is classified as an Alpha− global city, according to the GaWC 2024 ranking. The city proper has a population of 3.1 million and its urban area has a population of 16.7 million, making it the 21st most populous metropolitan area in the world.

It is known for its preserved eclectic European architecture and rich cultural life. It is a multicultural city that is home to multiple ethnic and religious groups, contributing to its culture as well as to the dialect spoken in the city and in other parts of the country. Since the 19th century, the city, and the country in general, has been a major recipient of millions of immigrants from all over the world, making it a melting pot where many ethnic groups live together. Buenos Aires is considered one of the most diverse cities of the Americas.

The city of Buenos Aires is an autonomous district and is neither part of Buenos Aires Province nor its capital. In 1880, after the Argentine Civil War, Buenos Aires was federalized and split from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores, both now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name of Autonomous City of Buenos Aires. Citizens elected their first chief of government in 1996. Previously, the mayor was directly appointed by the president of Argentina.

The Greater Buenos Aires conurbation includes several surrounding cities, which are located in the neighbouring districts of the Buenos Aires Province. It constitutes the fourth-most populous metropolitan area in the Americas. It is also the second largest city south of the Tropic of Capricorn. Buenos Aires has the highest human development of all Argentine administrative divisions.

Ciudad de Buenos Aires in Depth

History

In 1516, navigator and explorer Juan Díaz de Solís, navigating in the name of Spain, was the first European to reach the Río de la Plata. His expedition was cut short when he was killed during an attack by the native Charrúa tribe in what is now Uruguay. The city of Buenos Aires was first established as Ciudad de Nuestra Señora Santa María del Buen Ayre (literally "City of Our Lady Saint Mary of the Fair Winds") after Our Lady of Bonaria (Patroness Saint of Sardinia) on 2 February 1536 by a Spanish expedition led by Pedro de Mendoza. The settlement founded by Mendoza was located in what is today the San Telmo district of Buenos Aires, south of the city center.

More attacks by the indigenous people forced the settlers away, and in 1542, the site was abandoned.

Geography

The city of Buenos Aires lies in the pampa region, with the exception of some areas such as the Buenos Aires Ecological Reserve, the Boca Juniors' "sports city", Jorge Newbery Airport, the Puerto Madero neighborhood and the main port itself; these were all built on reclaimed land along the coasts of the Rio de la Plata (the world's widest river).

The region was formerly crossed by different streams and lagoons, some of which were refilled, and others tubed. Among the most important streams are the Maldonado, Vega, Medrano, Cildañez, and White. In 1908, as floods were damaging the city's infrastructure, many streams were channeled and rectified; furthermore, starting in 1919, most streams were enclosed.

Economy

Buenos Aires is the financial, industrial, and commercial hub of Argentina. The economy in the city proper alone, measured by gross geographic product (adjusted for purchasing power), totaled US$102.7 billion (US$34,200 per capita) in 2020 and amounts to nearly a quarter of Argentina's as a whole. Metro Buenos Aires, according to one well-quoted study, constitutes the 13th largest economy among the world's cities in 2005. The Buenos Aires Human Development Index (0.889 in 2019) is likewise high by international standards.

The city's services sector is diversified and well-developed by international standards, and accounts for 76 percent of its economy (compared to 59% for all of Argentina's). Advertising, in particular, plays a prominent role in the export of services at home and abroad.

Demographics

In the census of 2010, there were 2,891,082 people residing in the city. The population of Greater Buenos Aires was 13,147,638 according to 2010 census data. The population density in Buenos Aires proper was 13,680 inhabitants per square kilometer (35,400 inhabitants/sq mi), but only about 2,400 inhabitants per square kilometre (6,200 inhabitants/sq mi) in the suburbs.

Buenos Aires' population has hovered around 3 million since 1947, due to low birth rates and a slow migration to the suburbs.
