Buenos Aires

Buenos Aires, controlled by the government of the Autonomous City of Buenos Aires, is the <a href="/facts/Capital_city/aRTzKRH0">capital</a> and largest city of <a href="/facts/Argentina/aFSA5bAk">Argentina</a>. It is located on the southwest of the <a href="/facts/R%25C3%25ADo_de_la_Plata/FczwYLCG">Río de la Plata</a>. Buenos Aires is classified as an Alpha− <a href="/facts/Global_city/Lqv5NqA5">global city</a>, according to the <a href="/facts/Globalization_and_World_Cities_Research_Network/xdxbC98a">GaWC</a> 2024 ranking. The city proper has a population of 3.1 million and its urban area 16.7 million, making it the <a href="/facts/List_of_metropolitan_areas/5eVR5sk2">twentieth largest metropolitan area in the world</a>.
It is known for its preserved <a href="/facts/Eclecticism/vSnWaRky">eclectic</a> European architecture and rich <a href="/facts/Culture/c5JgMqpX">cultural life</a>. It is a <a href="/facts/Multiculturalism/jDbm9eo5">multicultural</a> 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 some other parts of the country. This is because since the 19th century, the city, and the country in general, has been a major recipient of millions of <a href="/facts/Immigration_to_Argentina/1xreUCkP">immigrants from all over the world</a>, making it a <a href="/facts/Melting_pot/Ao6n1rIB">melting pot</a> where several ethnic groups live together. Thus, Buenos Aires is considered one of the most diverse cities of <a href="/facts/The_Americas/hEuUTL4K">the Americas</a>.
The city of Buenos Aires is neither part of <a href="/facts/Buenos_Aires_Province/HkAcQKBN">Buenos Aires Province</a> nor its capital; it is an <a href="/facts/Autonomous_city/JSSGtnwR">autonomous</a> district. In 1880, after the <a href="/facts/Argentine_Civil_Wars/NsSCaCNQ">Argentine Civil War</a>, Buenos Aires was <a href="/facts/Federalization_of_Buenos_Aires/oByesQVc">federalized</a> and split from Buenos Aires Province. The <a href="/facts/City_limits/SvoUXwLT">city limits</a> were enlarged to include the towns of <a href="/facts/Belgrano%2c_Buenos_Aires/wzM9ojm5">Belgrano</a> and <a href="/facts/Flores%2c_Buenos_Aires/ugnfhhrt">Flores</a>; both now <a href="/facts/Neighbourhoods_of_Buenos_Aires/EAdrlRXw">neighborhoods of the city</a>. The <a href="/facts/1994_amendment_of_the_Argentine_Constitution/ELqjq6Yd">1994 constitutional amendment</a> granted the city <a href="/facts/Autonomous_area/JnUkBUJc">autonomy</a>, hence its formal name of Autonomous City of Buenos Aires. Thus, citizens elected their first <a href="/facts/List_of_mayors_and_chiefs_of_government_of_Buenos_Aires/7Xy050Va">Chief of Government</a> in 1996; previously, the Mayor was directly appointed by the <a href="/facts/President_of_Argentina/RJpPWGFK">President of Argentina</a>.
The <a href="/facts/Greater_Buenos_Aires/fjWYyFxD">Greater Buenos Aires</a> <a href="/facts/Conurbation/4deBIPSV">conurbation</a> includes several surrounding cities, which are located in the neighbouring <a href="/facts/Partidos_of_Buenos_Aires/3gUTv5Eu">districts</a> of the <a href="/facts/Buenos_Aires_Province/HkAcQKBN">Buenos Aires Province</a>. It constitutes the <a href="/facts/List_of_metropolitan_areas_in_the_Americas/KnM3amg7">fourth-most populous</a> metropolitan area in the <a href="/facts/Americas/hEuUTL4K">Americas</a>. It is also the second largest city south of the <a href="/facts/Tropic_of_Capricorn/9jhptsNX">Tropic of Capricorn</a>. Buenos Aires has the highest <a href="/facts/Human_Development_Index/hQpz064I">human development</a> of all Argentine administrative divisions and its <a href="/facts/Quality_of_life/37ljmgAH">quality of life</a> was ranked 91st in the world in 2018, being one of the best in <a href="/facts/Latin_America/Qmx9Jx2a">Latin America</a>.
