Buenos Aires
Buenos Aires ( or, ) is the capital and largest city of Argentina. The city is located on the western shore of the estuary of the Río de la Plata, on the continent's southeastern coast. The meaning of Buenos Aires is clean air or good air. The Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the third-largest conurbation in Latin America, with a population of around seventeen million. 

The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district.  In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province.  The city limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name: Ciudad Autónoma de Buenos Aires (Autonomous City of Buenos Aires). Its citizens first elected a chief of government (i.e. mayor) in 1996; before, the mayor was directly appointed by the President of the Republic.

Buenos Aires is, along with Mexico City and São Paulo, one of the three Latin American cities considered an 'alpha city' by the study GaWC5.  Buenos Aires' quality of life was ranked 81st in the world and one of the best in Latin America in 2012, with its per capita income among the three highest in the region.   It is the most visited city in South America (ahead of Rio de Janeiro) and the second most visited city of Latin America (behind Mexico City ).

Buenos Aires is a top tourist destination,  and is known for its European-style architecture  and rich cultural life.  Buenos Aires held the 1st Pan American Games in 1951 as well as hosting two venues in the 1978 FIFA World Cup. Buenos Aires will host the 2018 Summer Youth Olympics and the 2018 G20 summit. 

Buenos Aires defines itself as a multicultural city, being home to multiple ethnic and religious groups. Also, several languages are spoken in the city in addition to Spanish, contributing to its culture and the dialect spoken in the city and in some other parts of the country. This is because in the last 150 years 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 several ethnic groups live together and being considered as one of the most diverse cities in Latin America. 

Etymology

It is recorded under the archives of Aragonese that Catalan missionaries and Jesuits arriving in Cagliari (Sardinia) under the Spanish Crown, after its capture from the Pisans in 1324  established their headquarters on top of a hill that overlooked the city. The hill was known to them as Buen Ayre (or "Bonaria" in Sardinian language), as it was free of the foul smell prevalent in the old city (the castle area), which is adjacent to swampland. During the siege of Cagliari, the Aragonese built a sanctuary to the Virgin Mary on top of the hill. In 1335, King Alfonso the Gentle donated the church to the Mercedarians, who built an abbey that stands to this day. In the years after that, a story circulated, claiming that a statue of the Virgin Mary was retrieved from the sea after it miraculously helped to calm a storm in the Mediterranean Sea. The statue was placed in the abbey. Spanish sailors, especially Andalusians, venerated this image and frequently invoked the "Fair Winds" to aid them in their navigation and prevent shipwrecks. A sanctuary to the Virgin of Buen Ayre would be later erected in Seville. 

In the first foundation of Buenos Aires, Spanish sailors arrived thankfully in the River de la Plata by the blessings of the "Santa Maria de los Buenos Aires", the "Holy Virgin Mary of the Good Winds" who was said to have given them the good winds to reach the coast of what is today the modern city of Buenos Aires.  Pedro de Mendoza called the city "Holy Mary of the Fair Winds", a name suggested by the chaplain of Mendoza's expedition - a devotee of the Virgin of Buen Ayre  - after the Sardinian "Madonna de Bonaria"  (that is still to this day the patroness of Sardinia ). Mendoza’s settlement soon came under attack by indigenous people, and was abandoned in 1541. 

For many years, the name was attributed to a Sancho del Campo, who is said to have exclaimed: How fair are the winds of this land!, as he arrived. But Eduardo Madero, in 1882 after conducting extensive research in Spanish archives, ultimately concluded that the name was indeed closely linked with the devotion of the sailors to Our Lady of Buen Ayre. 

A second (and permanent) settlement was established in 1580 by Juan de Garay, who sailed down the Paraná River from Asunción (now the capital of Paraguay). Garay preserved the name originally chosen by Mendoza, calling the city Ciudad de la Santísima Trinidad y Puerto de Santa María del Buen Aire ("City of the Most Holy Trinity and Port of Saint Mary of the Fair Winds"). The short form "Buenos Aires" became the common usage during the 17th century. 

The usual abbreviation for Buenos Aires in Spanish is Bs.As.  It is common as well to refer to it as "B.A." or "BA" ). 

While "BA" is used commonly and more by expats that reside in the city, The locals use more often the abbreviation "Baires", in one word.

History

Colonial times

Seaman Juan Díaz de Solís, navigating in the name of Spain, was the first European to reach the Río de la Plata in 1516. 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.    A second (and permanent) settlement was established in 11 June 1580 by Juan de Garay, who arrived by sailing down the Paraná River from Asunción (now the capital of Paraguay). He dubbed the settlement "Santísima Trinidad" and its port became "Puerto de Santa María de los Buenos Aires."

From its earliest days, Buenos Aires depended primarily on trade. During most of the 17th and 18th centuries, Spanish ships were menaced by pirates, so they developed a complex system where ships with military protection were dispatched to Central America, cross the land, from there to Lima, Peru and from it to the inner cities of the viceroyalty. Because of this, products took a very long time to arrive in Buenos Aires, and the taxes generated by the transport made them prohibitive. This scheme frustrated the traders of Buenos Aires, and a thriving contraband industry developed. This also instilled a deep resentment in porteños towards the Spanish authorities.

Sensing these feelings, Charles III of Spain progressively eased the trade restrictions and finally declared Buenos Aires an open port in the late 18th century. The capture of Porto Bello by British forces also fueled the need to foster commerce via the Atlantic route, to the detriment of Lima-based trade. One of his rulings was to split a region from the Viceroyalty of Perú and create instead the Viceroyalty of the Río de la Plata, with Buenos Aires as the capital. However, Charles's placating actions did not have the desired effect, and the porteños, some of them versed in the ideology of the French Revolution, became even more convinced of the need for independence from Spain.

War of independence

During the British invasions of the Río de la Plata, British forces attacked Buenos Aires twice. In 1806 the British successfully invaded Buenos Aires, but an army from Montevideo led by Santiago de Liniers defeated them. In the brief period of British rule, the viceroy Rafael Sobremonte managed to escape to Córdoba and designated this city as capital. Buenos Aires became the capital again after its liberation, but Sobremonte could not resume his duties as viceroy. Santiago de Liniers, chosen as new viceroy, prepared the city against a possible new British attack and repelled the attempted invasion of 1807. The militarization generated in society changed the balance of power favorably for the criollos (in contrast to peninsulars), as well as the development of the Peninsular War in Spain. An attempt by the peninsular merchant Martín de Álzaga to remove Liniers and replace him with a Junta was defeated by the criollo armies. However, by 1810 it would be those same armies who would support a new revolutionary attempt, successfully removing the new viceroy Baltasar Hidalgo de Cisneros. This is known as the May Revolution, which is now celebrated as a national holiday. This event started the Argentine War of Independence, and many armies left Buenos Aires to fight the diverse strongholds of royalist resistance, with varying levels of success. The government was held first by two Juntas of many members, then by two triumvirates, and finally by a unipersonal office, the Supreme Director. Formal independence from Spain was declared in 1816, at the Congress of Tucumán. Buenos Aires managed to endure the whole Spanish American wars of independence without falling again under royalist rule.

Historically, Buenos Aires has been Argentina's main venue for liberal, free-trade and foreign ideas, while many of the provinces, especially to the north-west, advocated a more nationalistic and Catholic approach to political and social issues. Much of the internal tension in Argentina's history, starting with the centralist-federalist conflicts of the 19th century, can be traced back to these contrasting views. In the months immediately following 25 May Revolution, Buenos Aires sent a number of military envoys to the provinces with the intention of obtaining their approval. Many of these missions ended in violent clashes, and the enterprise fuelled tensions between the capital and the provinces.

In the 19th century the city was blockaded twice by naval forces: by the French from 1838 to 1840, and later by an Anglo-French expedition from 1845 to 1848. Both blockades failed to force the city into submission, and the foreign powers eventually desisted from their demands.

Modern history

During most of the 19th century, the political status of the city remained a sensitive subject. It was already capital of Buenos Aires Province, and between 1853 and 1860 it was the capital of the seceded State of Buenos Aires. The issue was fought out more than once on the battlefield, until the matter was finally settled in 1880 when the city was federalized and became the seat of government, with its mayor appointed by the president. The Casa Rosada became the seat of the president.

Health conditions in poor areas were negative, with high rates of tuberculosis.  Public-health physicians and politicians typically blamed both the poor themselves and their ramshackle tenement houses (conventillos) for the spread of the dreaded disease.  People ignored public-health campaigns to limit the spread of contagious diseases, such as the prohibition of spitting on the streets, the strict guidelines to care for infants and young children, and quarantines that separated families from ill loved ones. 

In addition to the wealth generated by the Buenos Aires Customs and the fertile pampas, railroad development in the second half of the 19th century increased the economic power of Buenos Aires as raw materials flowed into its factories. A leading destination for immigrants from Europe, particularly Italy and Spain, from 1880 to 1930 Buenos Aires became a multicultural city that ranked itself with the major European capitals. The Colón Theater became one of the world's top opera venues, and the city became the regional capital of radio, television, cinema, and theatre. The city's main avenues were built during those years, and the dawn of the 20th century saw the construction of South America's then-tallest buildings and the first underground system. A second construction boom from 1945 to 1980 reshaped downtown and much of the city.

Buenos Aires also attracted migrants from Argentina's provinces and neighboring countries. Shanty towns (villas miseria) started growing around the city's industrial areas during the 1930s, leading to pervasive social problems and social contrasts with the largely upwardly mobile Buenos Aires population. These laborers became the political base of Peronism, which emerged in Buenos Aires during the pivotal demonstration of 17 October 1945, at the Plaza de Mayo.  Industrial workers of the Greater Buenos Aires industrial belt have been Peronism's main support base ever since, and Plaza de Mayo became the site for demonstrations and many of the country's political events; on 16 June 1955, however, a splinter faction of the Navy bombed the Plaza de Mayo area, killing 364 civilians (see Bombing of Plaza de Mayo). This was the only time the city was attacked from the air, and the event was followed by a military uprising which deposed President Perón, three months later (see Revolución Libertadora).

In the 1970s the city suffered from the fighting between left-wing revolutionary movements (Montoneros, E.R.P. and F.A.R.) and the right-wing paramilitary group Triple A, supported by Isabel Perón, who became president of Argentina in 1974 after Juan Perón's death.

The March 1976 coup, led by General Jorge Videla, only escalated this conflict; the "Dirty War" resulted in 30,000 desaparecidos (people kidnapped and killed by the military during the years of the junta).  The silent marches of their mothers (Mothers of the Plaza de Mayo) are a well-known image of Argentines suffering during those times.

The dictatorship's appointed mayor, Osvaldo Cacciatore, also drew up plans for a network of freeways intended to relieve the city's acute traffic gridlock. The plan, however, called for a seemingly indiscriminate razing of residential areas and, though only three of the eight planned were put up at the time, they were mostly obtrusive raised freeways that continue to blight a number of formerly comfortable neighborhoods to this day.

The city was visited by Pope John Paul II twice: in 1982, and a second visit in 1987, which gathered some of the largest crowds in the city's history. The return of democracy in 1983 coincided with a cultural revival, and the 1990s saw an economic revival, particularly in the construction and financial sectors.

On 17 March 1992 a bomb exploded in the Israeli Embassy, killing 29 and injuring 242. Another explosion, on 18 July 1994 destroyed a building housing several Jewish organizations, killing 85 and injuring many more, these incidents marked the beginning of Middle Eastern terrorism to South America.

Following a 1993 agreement, the Argentine Constitution was amended to give Buenos Aires autonomy and rescinding, among other things, the president's right to appoint the city's mayor (as had been the case since 1880). On 30 June 1996, voters in Buenos Aires chose their first elected mayor (Chief of Government).

On 30 December 2004 a fire at the República Cromagnon nightclub killed almost 200 people, one of the greatest non-natural tragedies in Argentine history.

On 22 February 2012, a train crashed at Once Station. Fifty-one people were killed and more than 700 were injured; the dead and seriously injured were in the first two carriages, which was packed with people who had moved to the front of the train to be near the station exit on arrival.

Government and politics

Government structure

The Executive is held by the Chief of Government (), elected for a four-year term together with a Deputy Chief of Government, who presides over the 60-member Buenos Aires City Legislature. Each member of the Legislature is elected for a four-year term; half of the legislature is renewed every two years. Elections use the D'Hondt method of proportional representation. The Judicial branch is composed of the Supreme Court of Justice (Tribunal Superior de Justicia), the Magistrate's Council (Consejo de la Magistratura), the Public Ministry, and other City Courts. The Article 61 of the 1996 Constitution of the City of Buenos Aires states that "Suffrage is free, equal, secret, universal, compulsory and non-accumulative. Resident aliens enjoy this same right, with its corresponding obligations, on equal terms with Argentine citizens registered in the district, under the terms established by law." 

Legally, the city has less autonomy than the Provinces. In June 1996, shortly before the City's first Executive elections were held, the Argentine National Congress issued the National Law 24.588 (known as Ley Cafiero, after the Senator who advanced the projemacct) by which the authority over the 25,000-strong Argentine Federal Police and the responsibility over the federal institutions residing at the City (e.g., National Supreme Court of Justice buildings) would not be transferred from the National Government to the Autonomous City Government until a new consensus could be reached at the National Congress. Furthermore, it declared that the Port of Buenos Aires, along with some other places, would remain under constituted federal authorities.  , the deployment of the Metropolitan Police of Buenos Aires is ongoing. 

Beginning in 2007, the city has embarked on a new decentralization scheme, creating new Communes (comunas) which are to be managed by elected committees of seven members each.

Recent political history

In 1996, following the 1994 reform of the Argentine Constitution, the city held its first mayoral elections under the new statutes, with the mayor's title formally changed to "Head of Government". The winner was Fernando de la Rúa, who would later become President of Argentina from 1999 to 2001.

De la Rúa's successor, Aníbal Ibarra, won two popular elections, but was impeached (and ultimately deposed on 6 March 2006) as a result of the fire at the República Cromagnon nightclub. Jorge Telerman, who had been the acting mayor, was invested with the office. In the 2007 elections, Mauricio Macri of the Republican Proposal (PRO) party won the second-round of voting over Daniel Filmus of the Frente para la Victoria (FPV) party, taking office on 9 December 2007. In 2011, the elections went to a second round with 60.96% of the vote for PRO, compared to 39.04% for FPV, thus re-electing Macri as mayor of the city with María Eugenia Vidal as deputy mayor. 

The 2015 elections were the first to use an electronic voting system in the city, similar to the one used in Salta Province.  In these elections held on 5 July 2015, Macri stepped down as mayor and pursue his presidential bid and Horacio Rodríguez Larreta took his place as the mayoral candidate for PRO. In the first round of voting, FPV's Mariano Recalde obtained 21.78% of the vote, while Martín Lousteau of the ECO party obtained 25.59% and Larreta obtained 45.55%, meaning that the elections went to a second round since PRO was unable to secure the majority required for victory.  The second round was held on 19 July 2015 and Larreta obtained 51.6% of the vote, followed closely by Lousteau with 48.4%, thus PRO won the elections for a third term with Larreta as mayor and Diego Santilli as deputy. In these elections, PRO was stronger in the wealthier neighbourhoods of northern Buenos Aires, while ECO was stronger in the south of the city. 

National representation

Buenos Aires is represented in the Argentine Senate by three senators (, Federico Pinedo, Marta Varela and Pino Solanas).  The people of Buenos Aires also elect 25 national deputies to the Argentine Chamber of Deputies.

Demographics

Census data

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 (34,800 per mi2), but only about 2,400 per km2 (6,100 per mi2) in the suburbs.

The population of Buenos Aires proper has hovered around 3 million since 1947, due to low birth rates and a slow migration to the suburbs. The surrounding districts have, however, expanded over fivefold (to around 10 million) since then.

The 2001 census showed a relatively aged population: with 17% under the age of fifteen and 22% over sixty, the people of Buenos Aires have an age structure similar to those in most European cities. They are older than Argentines as a whole (of whom 28% were under 15, and 14% over 60). 

Two-thirds of the city's residents live in apartment buildings and 30% in single-family homes; 4% live in sub-standard housing. Measured in terms of income, the city's poverty rate was 8.4% in 2007 and, including the metro area, 20.6%. Other studies estimate that 4 million people in the metropolitan Buenos Aires area live in poverty. 

The city's resident labor force of 1.2 million in 2001 was mostly employed in the services sector, particularly social services (25%), commerce and tourism (20%) and business and financial services (17%); despite the city's role as Argentina's capital, public administration employed only 6%. Manufacturing still employed 10%.

Districts

The city is divided into barrios (neighborhoods) for administrative purposes, a division originally based on Catholic parroquias (parishes).  A common expression is that of the Cien barrios porteños ("One hundred porteño neighborhoods"), referring to a composition made popular in the 1940s by tango singer Alberto Castillo; however, Buenos Aires only consists of 48 official barrios. There are a several subdivisions of these districts, some with a long history and others that are the product of a real estate invention. A notable example is Palermo — the city's largest district — which has been subdivided into various barrios, including Palermo Soho, Palermo Hollywood, Las Cañitas and Palermo Viejo, among others. A newer scheme has divided the city into 15 comunas (communes). 

Population origin

The majority of porteños have European origins, mostly from the Calabrian, Ligurian, Piedmont, Lombardy, Sicily and Campania regions of Italy and from the Andalusian, Galician, Asturian, and Basque regions of Spain.    Unrestricted waves of European immigrants to Argentina starting in the mid-19th century significantly increased the country's population, even causing the number of porteños to triple between 1887 and 1915 from 500,000 to 1.5 million. 

Other significant European origins include German, Scottish, Norwegian, Polish, French, Portuguese, Swedish, Greek, Czech, Croatian, Dutch, Russian, Serbian, English, Hungarian and Bulgarian. In the 1980s and 1990s, there was a small wave of immigration from Romania and Ukraine.  There is a minority of criollo citizens, dating back to the Spanish colonial days. The Criollo and Spanish-aboriginal (mestizo) population in the city has increased mostly as a result of immigration from the inner provinces and from other countries such as neighboring Bolivia, Paraguay, Chile and Peru, since the second half of the 20th century .

The Jewish community in Greater Buenos Aires numbers around 250,000, and is the largest in Latin America. Most are of Northern, Western, Central, and Eastern European Ashkenazi origin, primarily Swedish, Dutch, Polish, German, and Russian Jews, with a significant Sephardic minority, mostly made up of Syrian Jews and Lebanese Jews. Important Lebanese, Georgians, Syrian and Armenian communities have had a significant presence in commerce and civic life since the beginning of the 20th century.

Most East Asian immigration in Buenos Aires comes from China. Chinese immigration is the fourth largest in Argentina, with the vast majority of them living in Buenos Aires and its metropolitan area.  In the 1980s, most of them were from Taiwan, but since the 1990s the majority of Chinese immigrants come from the continental province of Fujian. The mainland Chinese who came from Fujian mainly installed supermarkets throughout the city and the suburbs; these supermarkets are so common that, in average, there is one every two and a half blocks and are simply referred to as el chino ("the Chinese").  Japanese immigrants are mostly from the Okinawa Prefecture. They started the dry cleaning business in Argentina, an activity that is considered idiosyncratic to the Japanese immigrants in Buenos Aires.  Korean Immigration occurred after the division of Korea; they mainly settled in Flores and Once. 

In the , 2.1% of the population or 61,876 persons declared to be Amerindian or first-generation descendants of Amerindians in Buenos Aires (not including the 24 adjacent Partidos that make up Greater Buenos Aires). Amongst the 61,876 persons who are of indigenous origin, 15.9% are Quechua people, 15.9% are Guaraní, 15.5% are Aymara and 11% are Mapuche. Within the 24 adjacent Partidos, 186,640 persons or 1.9% of the total population declared themselves to be Amerindian. Amongst the 186,640 persons who are of indigenous origin, 21.2% are Guaraní, 19% are Toba, 11.3% are Mapuche, 10.5% are Quechua and 7.6% are Diaguita.

In the city, 15,764 people identified themselves as Afro-Argentine in the 2010 Census.

Religion

Most inhabitants are Roman Catholic, though studies in recent decades found that fewer than 20% are practicing.  Buenos Aires is the seat of a Roman Catholic metropolitan archbishop (the Catholic primate of Argentina), currently Archbishop Mario Poli. His predecessor, Cardinal Jorge Bergoglio, was elected to the Papacy as Pope Francis on 13 March 2013. There are Protestant, Orthodox Christian, Muslim, Jewish, Jehovah's Witnesses, Mormon, and Buddhist minorities. The city is home to the largest mosque in South America.  Also, irreligion in Buenos Aires is higher than in other parts of the country, with about a 18.0% of the porteños declaring themselves as either atheist or agnostic. 

Urban problems

Villas miserias range from small groups of precarious houses to larger, more organised communities with thousands of residents. In rural areas, the houses in the villas miserias might be made of mud and wood. Villas miseria are found around and inside the large cities of Buenos Aires, Rosario, Córdoba and Mendoza, among others. The villas draw people from several backgrounds. Some are local citizens who have fallen from an already precarious economic position. In most cases, a villa miseria is populated by the children and grandchildren of the original settlers, who have been unable to improve their economic status.

In addition, Buenos Aires does not have enough green space. On average it has below 2 m² of green space per person, ten times less than New York, seven times less than Madrid and five times less than Paris. The World Health Organization (WHO), in its concern for public health, produced a document on the subject stating that every city should have a minimum of 9 m² of green space per person. An optimal amount would sit between 10 and 15 m² per person.  

Geography

The limits of Buenos Aires proper are determined in the eastern part and north-east by the Rio de la Plata, in the southern part and southeast by the Riachuelo and to the northwest, west and Southwest by General Paz Avenue, a 24 km long highway that separates the province of Buenos Aires from the 203 km2 that form the city.

The city of Buenos Aires lies in the pampa region, except for some zones like the Buenos Aires Ecological Reserve, the Boca Juniors (football) Club "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 creeks and lagoons, some of which were refilled and others tubed. Among the most important creeks are Maldonado, Vega, Medrano, Cildañez and White. In 1908 many creeks were channelled and rectified, as floods were damaging the city's infrastructure. Starting in 1919, most creeks were enclosed. Notably, the Maldonado was tubed in 1954, and runs below Juan B. Justo Avenue.

Climate

Buenos Aires has a humid subtropical climate (Köppen Cfa), with very hot and humid summers and mild winters. The warmest month is January, with a daily average of . Most days see temperatures in the 28 to with nights between 16 to. Heat waves from Brazil can push temperatures above 35 °C, yet the city is subject to cold fronts that bring short periods of pleasant weather and crisp nights. Relative humidity is 64–70% in the summer, so the heat index is higher than the true air temperature. The highest temperature ever recorded was  on 29 January 1957.  Spring (September to middle December) and autumn (middle March to middle June) are generally mild and volatile, with averages temperatures of around 17 °C and frequent thunderstorms, especially during the spring.

Winters are temperate, though suburban areas often experience frost from May to August, as opposed to downtown Buenos Aires, which experiences the phenomenon only some times per season. Relative humidity averages in the upper 70s%, which means the city is noted for its moderate to heavy fogs during autumn and winter.  July is the coolest month, with an average temperature of . Cold spells originating from Antarctica occur almost every year, and combined with the high wintertime humidity, conditions in winter may feel much cooler than the measured temperature. Most days peak reach 12 to and drop to 3 to at night. Southerly winds may keep temperatures below 10 °C for a few days, whereas northerly winds may bring temperatures above 20 °C for a few days; these variations are normal.

The lowest temperature ever recorded in central Buenos Aires (Buenos Aires Central Observatory) was  on 9 July 1918.  Snow is very rare in the city: the last snowfall occurred on 9 July 2007 when, during the coldest winter in Argentina in almost 30 years, severe snowfalls and blizzards hit the country. It was the first major snowfall in the city in 89 years.   On 17 July 2010, in the midst of another cold winter, flurries struck the southern reaches of Buenos Aires, but not the central parts as occurred in 2007 or 1918.

Spring is very windy and variable: there may be heat waves with temperatures of 35 °C even in early October. Severe thunderstorms are likely between September and December.

The city receives  of rainfall per year. Rain can be expected at any time of year and hailstorms are not unusual.

Economy

Buenos Aires is the financial, industrial, and commercial hub of Argentina. The economy in the city proper alone, measured by Gross Domestic Product (adjusted for purchasing power), totaled US$375.8 billion (US$38,900 per capita) in 2016 and amounts to nearly a quarter of Argentina's as a whole.  Metro Buenos Aires, according to one well-quoted study, constitutes the 12nd largest economy among the world's cities.  The Buenos Aires Human Development Index (0.879 in 2015) is likewise high by international standards. 

Port

The port of Buenos Aires is one of the busiest in South America; navigable rivers by way of the Rio de la Plata connect the port to north-east Argentina, Brazil, Uruguay and Paraguay. As a result, it serves as the distribution hub for a vast area of the south-eastern region of the continent. The Port of Buenos Aires handles over 11 million revenue tons annually,  and Dock Sud, just south of the city proper, handles another 17 million metric tons.  Tax collection related to the port has caused many political problems in the past, including a conflict in 2008 that led to protests and a strike in the agricultural sector after the government raised export tariffs.

Services

The city's services sector is diversified and well-developed by international standards, and accounts for 76% 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. The financial and real-estate services sector is the largest, however, and contributes to 31% of the city's economy. Finance (about a third of this) in Buenos Aires is especially important to Argentina's banking system, accounting for nearly half the nation's bank deposits and lending. Nearly 300 hotels and another 300 hostels and bed & breakfasts are licensed for Tourism in Buenos Aires, and nearly half the rooms available were in four-star establishments or higher. 

Manufacturing

Manufacturing is, nevertheless, still prominent in the city's economy (16%) and, concentrated mainly in the southern part of the city. It benefits as much from high local purchasing power and a large local supply of skilled labor as it does from its relationship to massive agriculture and industry just outside the city limits. Construction activity in Buenos Aires has historically been among the most accurate indicators of national economic fortunes (see table at right), and since 2006 around 3 e6m2 of construction has been authorized annually. Meat, dairy, grain, tobacco, wool and leather products are processed or manufactured in the Buenos Aires metro area. Other leading industries are automobile manufacturing, oil refining, metalworking, machine building and the production of textiles, chemicals, clothing and beverages.

Government finances

The city's budget, per Mayor Macri's 2011 proposal, will include US$6 billion in revenues and US$6.3 billion in expenditures. The city relies on local income and capital gains taxes for 61% of its revenues, while federal revenue sharing will contribute 11%, property taxes, 9%, and vehicle taxes, 6%. Other revenues include user fees, fines and gambling duties. The city devotes 26% of its budget to education, 22% for health, 17% for public services and infrastructure, 16% for social welfare and culture, 12% in administrative costs and 4% for law enforcement. Buenos Aires maintains low debt levels and its service requires less than 3% of the budget. 

Culture

Strongly influenced by European culture, Buenos Aires is sometimes referred to as the "Paris of South America".   The city has the busiest live theatre industry in Latin America, with scores of theaters and productions.  In fact, every weekend, there are about 300 active theatres with plays, a number that places the city as 1st worldwide, more than either London, New York or Paris, cultural Meccas in themselves. The number of cultural festivals with more than 10 sites and 5 years of existence also places the city as 2nd worldwide, after Edinburgh. 

Buenos Aires is the site of the Teatro Colón, an internationally rated opera house.  There are several symphony orchestras and choral societies. The city has numerous museums related to history, fine arts, modern arts, decorative arts, popular arts, sacred art, arts and crafts, theatre and popular music, as well as the preserved homes of noted art collectors, writers, composers and artists. The city is home to hundreds of bookstores, public libraries and cultural associations (it is sometimes called "the city of books"), as well as the largest concentration of active theatres in Latin America. It has a world-famous zoo and botanical garden, a large number of landscaped parks and squares, as well as churches and places of worship of many denominations, many of which are architecturally noteworthy.

Art

Buenos Aires has a thriving arts culture,  with "a huge inventory of museums, ranging from obscure to world-class."  The barrios of Palermo and Recoleta are the city's traditional bastions in the diffusion of art, although in recent years there has been a tendency of appearance of exhibition venues in other districts such as Puerto Madero or La Boca; renowned venues include MALBA, the National Museum of Fine Arts, Fundación Proa, Faena Arts Center, and the Usina del Arte.  Other popular institutions are the Buenos Aires Museum of Modern Art, the Quinquela Martín Museum, the Evita Museum, the Fernández Blanco Museum, the José Hernández Museum, and the Palais de Glace, among others.  A traditional event that occurs once a year is La Noche de los Museos ("Night of the Museums"), when the city's museums, universities, and artistic spaces open their doors for free until early morning; it usually takes place in November.  

Buenos Aires has also become a prominent center of contemporary street art; its welcoming attitude has made it one of the world's top capitals of such expression. The city's turbulent modern political history has "bred an intense sense of expression in porteños," and urban art has been used to depict these stories and as a means of protest.  However, not all of its street art concerns politics, it is also used as a symbol of democracy and freedom of expression. Murals and graffiti are so common that they are considered "an everyday occurrence," and have become part of the urban landscape of barrios such as Palermo, Urquiza, Coghlan and San Telmo.  This has to do with the legality of such activities —provided that the building owner has consented—, and the receptiveness of local authorities, who even subsidize various works.  The abundance of places for urban artists to create their work, and the relatively lax rules for street art, have attracted international artists such as Blu, Jef Aérosol, Aryz, ROA, and Ron English. Guided tours to see murals and graffiti around the city have been growing steadily. 

Literature

Despite its short urban history, Buenos Aires has an abundant literary production; its mythical-literary network "has grown at the same rate at which the streets of the city earned its shores to the pampas and buildings stretched its shadow on the curb."  The city has at least 734 bookstores, more per person than any other city in the world.  Gabriela Adamo, former president of the city's annual book fair, relates the popularity of reading among its inhabitants to the wave of mass immigration in the late 19th and early 20th centuries, which created "a multicultural environment in which culture and the arts thrived." Publishing experts have also linked it to the city's obsession with psychoanalysis. The city also ranks third in terms of secondhand bookshops per inhabitant, most of them congregated in Corrientes Avenue. Arguably the most famous bookstore is El Ateneo Grand Splendid, a reformed theatre. The Guardian ranked it second in its list of "The world's 10 best bookshops" in 2008. 

The literary history of the country is strongly linked to Buenos Aires' cafés; some of the most important still exist, like Café Tortoni, Café La Biela, Esquina Homero Manzi, Confitería Las Violetas, Confitería London City and Confitería Hotel Castelar. The city hosts the National Library of the Argentine Republic, the largest library in the country. Every April, the Buenos Aires International Book Fair takes place, which describes itself as "the most important annual literary event in the Spanish speaking world."  Every year, it gathers more than one million visitors, and usually features the presence of prestigious international authors.

Language

Known as Rioplatense Spanish, Buenos Aires' Spanish (as that of other cities like Rosario and Montevideo, Uruguay) is characterised by voseo, yeísmo and aspiration of s in various contexts. It is heavily influenced by the dialects of Spanish spoken in Andalusia and Murcia. A phonetic study conducted by the Laboratory for Sensory Investigations of CONICET and the University of Toronto showed that the prosody of porteño is closer to the Neapolitan language of Italy than to any other spoken language. 

In the early 20th century, Argentina absorbed millions of immigrants, many of them Italians, who spoke mostly in their local dialects (mainly Neapolitan, Sicilian and Genoese). Their adoption of Spanish was gradual, creating a pidgin of Italian dialects and Spanish that was called cocoliche. Its usage declined around the 1950s.

Many Spanish immigrants were from Galicia, and Spaniards are still generically referred to in Argentina as gallegos (Galicians). Galician language, cuisine and culture had a major presence in the city for most of the 20th century. In recent years, descendants of Galician immigrants have led a mini-boom in Celtic music (which also highlighted the Welsh traditions of Patagonia).

Yiddish was commonly heard in Buenos Aires, especially in the Balvanera garment district and in Villa Crespo until the 1960s. Most of the newer immigrants learn Spanish quickly and assimilate into city life.

The Lunfardo argot originated within the prison population, and in time spread to all porteños. Lunfardo uses words from Italian dialects, from Brazilian Portuguese, from African and Caribbean languages and even from English. Lunfardo employs humorous tricks such as inverting the syllables within a word (vesre). Today, Lunfardo is mostly heard in tango lyrics;  the slang of the younger generations has been evolving away from it.

Music

According to the Harvard Dictionary of Music, "Argentina has one of the richest art music traditions and perhaps the most active contemporary musical life" in South America.  Buenos Aires boasts of several professional orchestras, including the Argentine National Symphony Orchestra, the Ensamble Musical de Buenos Aires and the Camerata Bariloche; as well as various conservatories that offer professional music education, like the Conservatorio Nacional Superior de Música. As a result of the growth and commercial prosperity of the city in the late 18th century, the theatre became a vital force in Argentine musical life, offering Italian and French operas and Spanish zarzuelas. Italian music was very influential during the 19th century and the early 20th century, in part because of immigration, but operas and salon music were also composed by Argentines, including Francisco Hargreaves and Juan Gutiérrez. A nationalist trend that drew from Argentine traditions, literature and folk music was an important force during the 19th century, including composers Alberto Williams, Julián Aguirre, Arturo Berutti and Felipe Boero. In the 1930s, composers such as Juan Carlos Paz and Alberto Ginastera "began to espouse a cosmopolitan and modernist style, influenced by twelve-tone techniques and serialism"; while avant-garde music thrived by the 1960s, with the Rockefeller Foundation financing the Centro Interamericano de Altos Estudios Musicales, which brought internationally famous composers to work and teach in Buenos Aires, also establishing an electronic music studio.

The Río de la Plata is known for being the birthplace of tango, which is considered an emblem of Buenos Aires.  The city considers itself the Tango World Capital, and as such hosts many related events, the most important being an annual festival and world tournament. The most important exponent of the genre is Carlos Gardel, followed by Aníbal Troilo; other important composers include Alfredo Gobbi, Ástor Piazzolla, Osvaldo Pugliese, Mariano Mores, Juan D'Arienzo and Juan Carlos Cobián.  Tango music experienced a period of splendor during the 1940s, while in the 1960s and 1970s nuevo tango appeared, incorporating elements of classical and jazz music. A contemporary trend is neotango (also known as electrotango), with exponents such as Bajofondo and Gotan Project. On 30 September 2009, UNESCO's Intergovernmental Committee of Intangible Heritage declared tango part of the world's cultural heritage, making Argentina eligible to receive financial assistance in safeguarding tango for future generations. 

During the mid-1960s, Buenos Aires was also the birthplace of Argentine rock, one of the most important non-English language forms of this music in the world. A new generation of musicians from the legendary bar "la Cueva" in Avenida Pueyrredón, were trying to reflect an everyday reality absent in popular music since tango.  The movement was dubbed "progressive music" by the specialized press, and included Almendra, Los Gatos and Manal.  These bands were the pillars of not only what is known in Argentina as rock nacional ("national rock"), but also rock en español as a whole.  The act of writing serious and artistics songs in Spanish was unprecedented, and established a rock identity in the country. Since then, the style has evolved and diversified steadily throughout the years, encompassing most of its subgenres. Luis Alberto Spinetta, born in Buenos Aires in 1950, enjoyed universal critical acclaim that distinguished him as one of the most important artists from the Rio de la Plata.  Since 2014, "Musician's Day" is celebrated in Argentina on January 23 to commemorate his birth.

A musical style that originated in the slums (locally, villas miseria) of Buenos Aires and its metropolitan area is cumbia villera, particularly popular among the lower classes of Argentina and its neighboring countries. It originated during the late 1990s, in the midst of an economic and social decline in Argentina.   It is characterized by basic, low-budget productions, and lyrics that focuse on crime, drugs, class conflict and police corruption, acting as a vehicle of expression for the marginal classes, describing the everyday life in which they are immersed. Because of its characteristics, cumbia villera has been compared to gangsta rap, protest song, punk rock and narcocorrido, among other styles. A recent phenomenon is the appearance of "cumbia cheta" (cheto meaning "posh"), a derivative performed and listened by the middle and upper class, which distances itself from the political protest of the 1990s and 2000s. 

The city hosts several music festivals every year. A popular genre is electronic dance music, with festivals including Creamfields BA, SAMC, Moonpark, and a local edition of Ultra Music Festival. Other well-known events include the Buenos Aires Jazz Festival, Personal Fest, Quilmes Rock and Pepsi Music. Some music festivals are held in Greater Buenos Aires, like Lollapalooza, which takes place at the Hipódromo de San Isidro in San Isidro.

Cinema

Argentine cinema history began in Buenos Aires with the first film exhibition on July 18, 1896 at the Teatro Odeón.   With his 1897 film, La bandera Argentina, Eugène Py became one of the first filmmakers of the country; the film features a waving Argentine flag located at Plaza de Mayo. In the early 20th century, the first cinema theatres of the country opened in Buenos Aires, and newsreels appeared, most notably El Viaje de Campos Salles a Buenos Aires. The real industry emerged with the advent of sound films, the first one being Muñequitas porteñas (1931). The newly founded Argentina Sono Film released ¡Tango! in 1933, the first integral sound production in the country. During the 1930s and the 1940s (commonly referred as the "Golden Age" of Argentine ciema), most films revolved around the city of Buenos Aires and tango, reflected in titles such as La vida es un tango, El alma del bandoneón, Adiós Buenos Aires, El Cantor de Buenos Aires and Buenos Aires canta. During the 1960s, in response to large studio productions, the "Generation of the 60s" appeared, a group of filmmakers that produced the first modernist films in Argentina. These included Manuel Antín, Lautaro Murúa and René Mugica, among others.  During the late 1960s, clandestine exhibitions presented essay films of social protest, the work of Grupo Cine Liberación and Grupo Cine de la Base, who advocated what they called "Third Cinema". One of the most notable films of these movement is La hora de los hornos (1968) by Fernando Solanas.

Located in Buenos Aires is the Pablo Ducrós Hicken Museum of Cinema, the only one in the country dedicated to Argentine cinema and a pioneer of its kind in Latin America.  Every year, the city hosts the Buenos Aires International Festival of Independent Cinema (BAFICI), which, in its 2015 edition, featured 412 films from 37 countries, and an attendance of 380 thousand people.  Buenos Aires also hosts various other festivals and film cycles, like the Buenos Aires Rojo Sangre, devoted to horror.

Fashion

Buenos Aires is an important regional fashion capital, and its inhabitants have been historically characterized as "fashion-conscious".    According to Global Language Monitor,  the city ranks third in Latin America after São Paulo and Rio de Janeiro. 
  In 2005, Buenos Aires was appointed as the first UNESCO City of Design.  The city received this title once again in 2007. 

Buenos Aires hosts many fashion events. The most important is BAFWEEK that is held twice a year. It's been held since 2001 and is often a good chance for national designers to display their collections.  BAAM Argentina Fashion Week, which considers itself the "most prestigious fashion week of the country",  is another prominent event which has been named one of the most important fashion weeks worldwide by the World Fashion Organization and World Fashion Week. 

The neighbourhood of Palermo, mainly the area known as Soho, is where the latest fashion and design trends are presented. The "sub-barrio" of Palermo Viejo is also a popular port of call for fashion in the city. An increasing number of young, independent designers are also setting up their own shops in the bohemian neighbourhood of San Telmo, known for its wide variety of markets and antique shops. Recoleta, on the other hand, is the quintessential neighbourhood for exclusive and upscale fashion houses.  In particular, Avenida Alvear is home to the most exclusive representatives of haute couture in the city. 

Cityscape

Architecture

Buenos Aires architecture is characterized by its eclectic nature, with elements resembling Barcelona, Paris and Madrid. There is a mix, due to immigration, of Colonial, Art Deco, Art Nouveau, Neo-Gothic and French Bourbon styles.  Italian and French influences increased after the declaration of independence at the beginning of the 19th century, though the academic style persisted until the first decades of the 20th century.

Attempts at renovation took place during the second half of the 19th century and the beginning of the 20th, when European influences penetrated into the country, reflected by several buildings of Buenos Aires such as the Iglesia Santa Felicitas by Ernesto Bunge; the Palace of Justice, the National Congress, all of them by Vittorio Meano, and the Teatro Colón, by Francesco Tamburini and Vittorio Meano.

The simplicity of the Rioplatense baroque style can be clearly seen in Buenos Aires through the works of Italian architects such as André Blanqui and Antonio Masella, in the churches of San Ignacio, Nuestra Señora del Pilar, the Cathedral and the Cabildo.

In 1912 the Basilica del Santisimo Sacramento was opened to the public. Totally built by the generous donation of Mrs. Mercedes Castellanos de Anchorena, Argentina's most prominent family, the church is an excellent example of French neo-classicism. With extremely high-grade decorations in its interior, the magnificent Mutin-Cavaillé coll organ (the biggest ever installed in an Argentine church with more than four-thousand tubes and four manuals) presided the nave. The altar is full of marble, and was the biggest ever built in South America at that time. 

In 1919 the construction of Palacio Barolo began. This was South America's tallest building at the time, and was the first Argentine skyscraper built with concrete (1919–1923).  The building was equipped with 9 elevators, plus a 20-metre high lobby hall with paintings in the ceiling and Latin phrases embossed in golden bronze letters. A 300,000-candela beacon was installed at the top (110 m), making the building visible even from Uruguay. In 2009 the Barolo Palace went under an exhausive restoration, and the beacon was made operational again.

In 1936 the Kavanagh building was inaugurated, with 120 m height, 12 elevators (provided by Otis) and the world's first central air-conditioning system (provided by north-American company "Carrier"), is still an architectural landmark in Buenos Aires. 

The architecture of the second half of the 20th century continued to reproduce French neoclassic models, such as the headquarters of the Banco de la Nación Argentina built by Alejandro Bustillo, and the Museo Hispanoamericano de Buenos Aires of Martín Noel. However, since the 1930s the influence of Le Corbusier and European rationalism consolidated in a group of young architects from the University of Tucumán, among whom Amancio Williams stands out. The construction of skyscrapers proliferated in Buenos Aires until the 1950s. Newer modern high-technology buildings by Argentine architects in the last years of the 20th century and the beginning of the 21st include the Le Parc Tower by Mario Álvarez, the Torre Fortabat by Sánchez Elía and the Repsol-YPF tower by César Pelli.

Education

Primary education

Primary education comprise grades 1–7. Most primary schools in the city still adhere to the traditional seven-year primary school, but kids can do grades 1–6 if their high schools lasts 6 years, such as ORT Argentina.

Secondary education

Secondary education in Argentina is called Polimodal ("polymodal", that is, having multiple modes), since it allows the student to choose his/her orientation. Polimodal is usually 3 years of schooling, although some schools have a fourth year. Before entering the first year of polimodal, students choose an orientation, among these five: Humanities and Social Sciences, Economics and Management of Organizations, Art and Design, Health and Sport and Biology and Natural Sciences.

Nevertheless, in Buenos Aires, secondary education consists of 5 years, called from 1st year to 5th year, as opposed to primary education's 1st to 7th grade. Most schools don't require students to choose their orientation, as they study the basic such as maths, biology, art, history and technology, but there are schools that do, whether they are orientated to a certain profession or they have orientations to choose from when they reach a specific year.

Some high schools depend on the University of Buenos Aires, and these require an admission course when students are taking the last year of high school. These high schools are ILSE, CNBA, Escuela Superior de Comercio Carlos Pellegrini and Escuela de Educación Técnica Profesional en Producción Agropecuaria y Agroalimentaria (School of Professional Technique Education in Agricultural and Agri-food Production). The last two do have a specific orientation.

In December 2006 the Chamber of Deputies of the Argentine Congress passed a new National Education Law restoring the old system of primary followed by secondary education, making secondary education obligatory and a right, and increasing the length of compulsory education to 13 years. The government vowed to put the law in effect gradually, starting in 2007. 

University education

There are many public universities in Argentina, as well as a number of private universities. The University of Buenos Aires, one of the top learning institutions in South America, has produced five Nobel Prize winners and provides taxpayer-funded education for students from all around the globe.    Buenos Aires is a major center for psychoanalysis, particularly the Lacanian school. Buenos Aires is home to several private universities of different quality, such as: Universidad Argentina de la Empresa, Buenos Aires Institute of Technology, CEMA University, Favaloro University, Pontifical Catholic University of Argentina, University of Belgrano, University of Palermo, University of Salvador, Universidad Abierta Interamericana, Universidad John F. Kennedy, Universidad de Ciencias Empresariales y Sociales, Universidad del Museo Social Argentino, Universidad Austral and Torcuato di Tella University.

Tourism

According to the World Travel & Tourism Council, tourism has been growing in the Argentine capital since 2002. In a survey by the travel and tourism publication Travel + Leisure Magazine in 2008, travellers voted Buenos Aires the second most desirable city to visit after Florence, Italy.  In 2008, an estimated 2.5 million visitors visited the city. 

Visitors have many options such as going to a tango show, an estancia in the Province of Buenos Aires, or enjoying the traditional asado. New tourist circuits have recently evolved, devoted to famous Argentines such as Carlos Gardel, Eva Perón or Jorge Luis Borges. Before 2011, due to the favourable exchange rate, its shopping centres such as Alto Palermo, Paseo Alcorta, Patio Bullrich, Abasto de Buenos Aires and Galerías Pacífico were frequently visited by tourists. The exchange rate today has hampered tourism and shopping in particular. Notable consumer brands such as Tiffany & Co. have abandoned the country due to the exchange rate and import restrictions. The city also plays host to musical festivals, some of the largest of which are Quilmes Rock, Creamfields BA, Ultra Music Festival (Buenos Aires) and the Buenos Aires Jazz Festival.

Buenos Aires has also become "a Latin American gay-tourism."  An important factor was Argentina's 2001 financial crisis, with the subsequent favorable exchange rate attracting more foreign tourists.  Due to the existence of gay-friendly sites, the civil union law of 2002, and the openness of barrios such as Recoleta and Palermo, by 2003 Buenos Aires was being called "Latin America's gay capital". LGBT tourism remains a sector in the city, and points to its nightlife, cultural and artistic diversity, and Argentina's 2010 legalization of same-sex marriage (the first country in Latin America).

Transport

Local roads and personal transport

 
Buenos Aires is based on a square, rectangular grid pattern, save for natural barriers or the relatively rare developments explicitly designed otherwise (notably, the neighbourhood of Parque Chas). The rectangular grid provides for square blocks named manzanas, with a length of roughly 110 m. Pedestrian zones in the city centre, like Florida Street are partially car-free and always bustling, access provided by bus and the Underground (subte) Line C. Buenos Aires, for the most part, is a very walkable city and the majority of residents in Buenos Aires use public transport.

Two diagonal avenues in the city centre alleviate traffic and provide better access to Plaza de Mayo. Most avenues running into and out of the city centre are one-way and feature six or more lanes, with computer-controlled green waves to speed up traffic outside of peak times.

The city's principal avenues include the 140 m-wide July 9 Avenue, the over-35 km-long Rivadavia Avenue,  and Corrientes Avenue, the main thoroughfare of culture and entertainment.

In the 1940s and 1950s the General Paz Avenue beltway that surrounds the city along its border with Buenos Aires Province and freeways leading to the new international airport and to the northern suburbs heralded a new era in Buenos Aires traffic. Encouraged by pro-automaker policies pursued towards the end of the Perón (1955) and Frondizi administrations (1958–62) in particular, auto sales nationally grew from an average of 30,000 during the 1920–57 era to around 250,000 in the 1970s and over 600,000 in 2008.  Today, over 1.8 million vehicles (nearly one-fifth of Argentina's total) are registered in Buenos Aires. 

Toll motorways opened in the late 1970s by then-mayor Osvaldo Cacciatore provided fast access to the city centre and are today used by over a million vehicles daily.  Cacciatore likewise had financial district streets (roughly one square km in area) closed to private cars during daytime. Most major avenues are, however, gridlocked at peak hours. Following the economic mini-boom of the 1990s, record numbers started commuting by car and congestion increased, as did the time-honored Argentine custom of taking weekends off in the countryside.

Cycling

In December 2010, the city government launched a bicycle sharing program with bicycles free for hire upon  registration. Located in mostly central areas, there are 31 rental stations throughout the city providing over 850 bicycles to be picked up and dropped off at any station within an hour.  , the city has constructed 110 km of protected bicycle lanes and has plans to construct another 100 km.  In 2015, the stations were automated and the service became 24 hours through use of a smart card or mobile phone application.

Local public transport

Commuter rail

The Buenos Aires commuter rail system has seven lines:

*Belgrano Norte Line
*Belgrano Sur Line
*Roca Line
*San Martín Line
*Sarmiento Line
*Mitre Line
*Urquiza Line

The Buenos Aires commuter network system is very extensive: every day more than 1.3 million people commute to the Argentine capital. These suburban trains operate between 4 am and 1 am. The Buenos Aires commuter rail network also connects the city with long-distance rail services to Rosario and Córdoba, among other metropolitan areas. There are four principal terminals for both long-distance and local passenger services in the city centre: Constitucion, Retiro, Federico Lacroze and Once, while Buenos Aires station is a minor terminus.

Commuter rail in the city is mostly operated by the state-owned Trenes Argentinos, though the Urquiza Line and Belgrano Norte Line are operated by private companies Metrovías and Ferrovías respectively.    All services had been operated by Ferrocarriles Argentinos until the company's privatisation in 1993, and were then operated by a series of private companies until the lines were put back under state control following a series of high-profile accidents.  

Since 2013, there has been a series of large investments on the network, with all lines (with the exception of the Urquiza Line) receiving new rolling stock, along with widespread infrastructure improvements, track replacement, electrification work, refurbishments of stations and building entirely new stations.    Similarly, almost all level crossings have been replaced by underpasses and overpasses in the city, with plans to replace all of them in the near future.  One of the most major projects under way is the electrification of the remaining segments of the Roca Line – the most widely used in the network – and also moving the entire section of the Sarmiento Line which runs through the centre of the city underground to allow for better frequencies on the line and reduce congestion above ground.  

There are also three other major projects on the table. The first would elevate a large segment of the San Martín Line which runs through the centre of the city and electrify the line, while the second would see the electrification and extension of the Belgrano Sur Line to Constitucion station in the centre of the city.   If these two projects are completed, then the Belgrano Norte Line would be the only diesel line to run through the city. The third and most ambitious is to build a series of underground tunnels between three of the city's railway terminals with a large underground central station underneath the Obelisk, connecting all the commuter railway lines in a network dubbed the Red de Expresos Regionales. 

Underground

The Buenos Aires Underground (locally known as subte, from "subterráneo" meaning underground or subway), is a high-yield system providing access to various parts of the city. Opened in 1913, it is the oldest underground system in the Southern Hemisphere and oldest in the Spanish-speaking world. The system has six underground lines and one overground line, named by letters (A to E, and H) and there are 100 stations, and  of route, including the Premetro line.  An expansion program is underway to extend existing lines into the outer neighborhoods and add a new north-south line. Route length is expected to reach 89 km by 2011.

Line A is the oldest one (service opened to public in 1913) and stations kept the "belle-époque" decoration, while the original rolling stock from 1913, affectionately known as Las Brujas were retired from the line in 2013. Daily ridership on weekdays is 1.7 million and on the increase.   Fares remain relatively cheap, although the city government raised fares by over 125% in January 2012. A single journey, with unlimited interchanges between lines, now costs AR$3.50, which is roughly USD$0.60. 

The most recent expansions to the network were the addition of numerous stations to the network in 2013: San José de Flores and San Pedrito to Line A, Echeverría and Juan Manuel de Rosas to Line B and Hospitales to Line H. Current works include the completion of Line H northwards and addition of three new stations to Line E in the centre of the city.   The construction of Line F is due to commence in 2015,  while two other lines are planned for construction in the future.

Tramways

Buenos Aires had an extensive street railway (tram) system with over 857 km of track, which was dismantled during the 1960s in favour of bus transportation, but surface rail transport has made a small comeback in some parts of the city. The PreMetro or Line E2 is a  light rail line that connects with Underground Line E at Plaza de los Virreyes station and runs to General Savio and Centro Cívico. It is operated by Metrovías. The official inauguration took place on 27 August 1987.

A 2 km modern tramway, the Tranvía del Este, opened in 2007 in the Puerto Madero district, using two tramcars on temporary loan. However, plans to extend the line and acquire a fleet of trams did not come to fruition, and declining patronage led to the line's closure in October 2012.   A heritage streetcar maintained by tram fans operates on weekends, near the Primera Junta line A Underground station in the Caballito neighbourhood.

Buses

There are over 150 city bus lines called Colectivos, each one managed by an individual company. These compete with each other, and attract exceptionally high use with virtually no public financial support.  Their frequency makes them equal to the underground systems of other cities, but buses cover a far wider area than the underground system.

There have been reports of organized crime controlling the access of taxis to the city airports and other major destinations. Taxi drivers are known for trying to take advantage of tourists.  Radio-link companies provide reliable and safe service; many such companies provide incentives for frequent users. Low-fare limo services, known as remises, have become popular in recent years.
