Buenos Aires City Guide: Role in Argentina

The Autonomous City of Buenos Aires, known by its initials CABA, is the national capital and a district of its own. It sits inside a larger urban area, because the city and 24 neighbouring districts form one conurbation, the city’s statistics institute says.

The institute, called IDECBA, is the city’s official statistics office. Peso figures here convert at the central bank’s official rate of ARS 1,551 per US$1 on 3 November 2026.

Population and the 15 Comunas

Argentina’s national statistics office, INDEC, projects 3,065,991 residents for 2026, down from 3,121,189 in 2022. That is a fall of 55,198 people, or 1.8%, over four years.

The city law of 1 September 2005, Law 1,777, divides the city into 15 comunas. Comunas are the local districts the institute uses for its neighbourhood statistics.

Comuna 1, which covers the old centre and the port district, is the largest with a projected 250,968 residents in 2026. Comuna 7 follows with 245,736, then Comuna 13 with 240,823 and Comuna 4 with 239,104.

Comuna 14, the Palermo area, and Comuna 8, in the far south, each hold about 235,000. The smallest is Comuna 2, centred on Recoleta, with 150,090.

Only Comunas 1, 8 and 14 grow in the projection, while the other 12 shrink. INDEC builds it from the 2022 census with assumed birth, death and migration rates.

The Economy of Buenos Aires

The city’s gross geographic product, its local GDP, grew 0.3% in the second quarter of 2026 against a year earlier. Seasonally adjusted, it fell 0.2% from the first quarter, the city statistics institute says.

The first quarter of 2026 had risen only 0.8% on a year earlier, and the second quarter of 2025 had grown 5.9%. The institute describes a slowdown that began in the third quarter of 2025.

Financial services grew 7.7% in the second quarter of 2026 from a year earlier and were the largest positive contributor. Transport, storage and communications added 0.9%.

Commerce shrank 2.2% and manufacturing 1.8%, the institute says. Weaker wholesale trade in medicines and lower output of clothing, chemicals and plastics explain much of that.

Poverty, Incomes and Daily Costs

In the second quarter of 2026, 21.9% of the city’s residents lived below the poverty line, about 675,000 people. That compares with 21.1% a year earlier, and 6.3% were in extreme poverty, up from 6.0%.

By household, 17.3% were poor (239,000 households) and 4.5% were in extreme poverty (63,000). The institute’s middle class, earning 1.25 to 4 times its total basket cost, held 53.5% of households (737,000).

In September 2026 the poverty line for a homeowning couple with two children was ARS 1,687,299 a month (about US$1,088). A year earlier it was ARS 1,255,934 (about US$810), a rise of 34.3%.

For one adult who owns his home, the line was ARS 615,282 (about US$397). The institute’s full consumption basket for that adult cost ARS 775,948 (about US$500).

Who Governs the City

The city elects its own head of government, Jorge Macri, who runs the executive branch. The 60-member Legislature writes the city’s laws and budget, and Clara Muzzio presides over it.

As of 4 November 2026, the Legislature’s own site lists seven blocs. Fuerza por Buenos Aires holds 20 seats and La Libertad Avanza, President Javier Milei’s party, holds 14.

The bloc Vamos por más holds 12 seats, Confianza y Desarrollo six and Ciudadanos Unidos with the Radical Civic Union (UCR) five. The Trotskyist-led Frente de Izquierda has two seats and Transformación one.

No bloc holds a majority of 31, so every budget needs deals across blocs. The next ordinary session is listed for Thursday, 5 November 2026.

Local politics matter nationally because the city votes in the 2027 presidential race like every other district. Its bloc deals also show how far national parties can cooperate.

Security and Safety in Buenos Aires

The US State Department tells travellers to exercise normal precautions in Argentina, noting that some areas carry more risk. Its Buenos Aires warnings name street crime in San Telmo, La Boca, Retiro and on Florida Street.

It lists pickpockets, bag snatchers and thieves on motorcycles who work in pairs. It also warns of taxi scams around the airport, express kidnappings, ATM robberies and frequent demonstrations.

The advisory page shows an update date of 11 April 2024, so check the current version before you travel. The Rio Times Argentina security guide covers the national picture.

No confirmed city-wide homicide or theft rate for 2025 or 2026 was found at a primary source for this guide. Crime figures by comuna are therefore left out.

Getting There and Getting Around

Private US citizens need no visa for tourism or business stays of up to 90 days in Argentina, the State Department says. Your passport must be valid on entry, with one blank page.

Visitors may not bring in undeclared cash above US$10,000, and the limit is US$5,000 for children under 16. Use pre-arranged rides or radio taxis, as the State Department advises.

The city shares its commuter belt with the 24 districts around it, so daily transport crosses jurisdictions. Subway, airport and bus data were not checked at a primary source for this guide.

For events and neighbourhood tips, read the Rio Times guide to what to do in Buenos Aires in November 2026. The Buenos Aires expat city page covers moving there.

What It Means for US Readers

Americans can visit for up to 90 days without a visa. Keep valuables out of sight in San Telmo, La Boca and Retiro, and avoid street protests.

Investors should watch the city’s slowdown, with output up only 0.3% in the second quarter of 2026, and poverty near 22%. Both feed into national politics and the 2027 vote.

Residents and expats should budget for rapid price rises, since the poverty line, which tracks local prices, rose 34.3% in a year. The Rio Times guide to Argentina and the United States explains trade and visas.

What Prediction Markets Say

Polymarket, where users bet real money, runs a market on who wins Argentina’s 2027 presidential election. On 4 November at 9:40 a.m. ET it priced Javier Milei, the sitting president, at 45.5%.

Axel Kicillof, the governor of Buenos Aires Province, stood at 30.5%, and Sergio Massa, a former economy minister, at 14.3%. About US$1.26 million has traded on the whole market.

The city of Buenos Aires votes in that race like every other district. Its slowdown and 21.9% poverty rate feed the national argument over Milei’s economic policy.

Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.

What Is Not Known

The parties behind the blocs Fuerza por Buenos Aires, Vamos por más, Confianza y Desarrollo and Transformación were not verified. The party ties of individual legislators were not checked either.

The city’s 2022 census count, foreign-born share, income per head, tourism numbers and budget were not confirmed at primary sources. Neighbourhood-level crime, subway, airport and bus figures are also missing.

How the city’s slowdown will play out in the 2027 election is not known. Population projections beyond 2026 may be revised when INDEC publishes new estimates.
