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. Its quality of life was ranked 97th in the world in 2024, being one of the best in Latin America.
