1. São Paulo

São Paulo, the largest city in Brazil and South America, plays a central role in the continent’s economy. It accounts for nearly a quarter of Brazil’s GDP and is home to major industries like finance, manufacturing, and services.

The city’s population continues to grow, reaching over 22.8 million in 2024, with its metropolitan area expanding rapidly.

While São Paulo is a global financial hub, it also deals with significant challenges, especially regarding crime. Though the city has made strides in reducing its crime rates, theft and violent crime remain prevalent in certain areas.

With a crime index of 45.51, it’s critical to note that some regions, like the Republica district, face higher risks, while wealthier areas are generally safer.

Despite these issues, São Paulo draws nearly 15 million tourists each year, who come for its vibrant culture, nightlife, and gastronomy. It’s also a student hub, with close to a million students in its universities and colleges.

On a broader scale, Brazil continues to face crime challenges, with cities like Brasília and Rio de Janeiro also dealing with high crime rates. In São Paulo, however, the government has made progress in reducing homicides and other serious crimes, though more work is needed.

São Paulo is implementing the Smart Sampa project, which includes the deployment of 20,000 facial recognition cameras.

2. Buenos Aires

Buenos Aires is the second-largest city in South America, with a population of over 15.6 million in 2024. Known for its rich cultural history, vibrant neighborhoods, and as the birthplace of tango, the city attracts tourists from around the world.

It’s not just a cultural hub but also a significant economic player in Argentina, with finance, services, and tourism being the major sectors driving growth. The metropolitan area is densely populated, with about 7,700 people per square kilometer.

While Buenos Aires has been making strides in reducing crime, like many large cities, it faces challenges. Since 2020, the overall crime rate has dropped by 33%, with significant reductions in robberies, assaults, and homicides.

However, some areas still experience higher risks, particularly for theft and pickpocketing, especially in tourist-heavy spots. Yet, the city’s commitment to public safety has helped reduce incidents in residential areas and on public transport.

The city also plays a central role in Argentina’s economy, with significant contributions from its financial sector and a thriving tourism industry that keeps growing.

For visitors, Buenos Aires offers a mix of history, modernity, and unique experiences, from its world-famous cuisine to bustling markets and cultural festivals.

Buenos Aires is making a name for itself as a digital nomad hotspot. The city has launched several initiatives to attract remote workers, offering long-stay visas and promoting its affordable cost of living compared to other major cities.

3. Rio de Janeiro

Rio de Janeiro is Brazil’s second-largest city, with a population of 13.8 million in 2024. Famous for its beautiful beaches and world-renowned Carnival, the city also plays a major economic role, driven by key industries like oil, tourism, and finance.

However, like other large Brazilian cities, Rio faces significant challenges with crime, particularly in areas like favelas, where violence and drug-related crimes are frequent.

The homicide rate in Rio remains one of the highest in Brazil, with more than 40 murders per 100,000 residents.

Despite efforts to reduce crime, many neighborhoods, especially in the northern suburbs and favelas, continue to struggle with safety issues, making it a city of stark contrasts.

Organized crime and police militias add to the complex security landscape, and ongoing clashes between criminal groups and law enforcement are common.

Yet, Rio continues to attract millions of tourists each year, who come for its cultural attractions, including the iconic Christ the Redeemer statue, Sugarloaf Mountain, and the famous beaches of Copacabana and Ipanema.

The city is expected to create about 380,000 new jobs by the end of 2024, largely driven by growth in the service and tourism sectors.

4. Bogotá

Bogotá, Colombia’s capital and largest city, continues to grow, reaching a population of 11.6 million in 2024. The city serves as Colombia’s primary economic hub, with key sectors including finance, trade, and manufacturing.

Additionally, the city has seen significant growth in its digital economy, with numerous startups emerging in recent years.

However, like other major Latin American cities, Bogotá faces rising crime.

Armed robberies and violent crime remain a challenge, with many residents expressing concerns about security. In response, local authorities have implemented a “shock mode” to curb rising crime rates, increasing police presence across key areas of the city.

Despite efforts to reduce violence, security remains an issue for both residents and visitors, especially in certain districts.

Bogotá accounted for 36.7% of all international visitors to Colombia in the first quarter of 2024

5. Lima

Lima, the capital of Peru, remains a crucial city in South America in 2024. With a population of 11.3 million, it continues to be the economic backbone of Peru.

Lima’s economy is driven by manufacturing, trade, and services, while the city remains a popular tourist destination due to its rich cultural history and renowned gastronomy.

Crime in Lima, however, is a growing concern. The city has a homicide rate of 7.2 per 100,000 people, and robberies are reported at a rate of 94.3 per 100,000.

Extortion and violent crimes, including contract killings, are also on the rise, contributing to a general sense of insecurity.

Despite increased government spending on law enforcement and patrols, many neighborhoods continue to face significant safety issues.

Lima’s gastronomy sector is thriving, with the city being recognized as a global culinary destination in 2024. The Mistura Festival continues to draw thousands of food enthusiasts.

6. Santiago

Santiago, the capital of Chile, is a bustling metropolis with a population of nearly 7 million in 2024. It plays a crucial role in the country’s economy, contributing significantly through sectors like finance, retail, and manufacturing.

However, crime remains a concern in the city. Santiago has a crime index of 63.43, with a homicide rate of 10.1 per 100,000 people, reflecting ongoing challenges in controlling theft, assault, and drug-related crimes.

Despite this, the city maintains its appeal, drawing tourists with its historical landmarks, proximity to the Andes, and world-class wineries. It is important for both residents and visitors to stay cautious, especially at night, due to higher risks in certain areas.

Santiago’s international airport expansion project is set to be completed in late 2024, increasing the airport’s capacity by 50% to handle growing passenger numbers.

7. Belo Horizonte

Belo Horizonte is the third-largest metropolitan area in Brazil, with a population of 6.3 million in 2024. The city’s economy is largely driven by the mining and steel industries, and it serves as a hub for manufacturing and services in the region.

It’s also recognized for its rich cultural offerings, with numerous museums, parks, and historic architecture drawing tourists.

Despite its economic strengths, Belo Horizonte faces significant crime challenges. The city’s crime index is 60.39, and the homicide rate stands at 30 per 100,000 people. Issues like theft, vandalism, and violent crimes such as assault and armed robbery remain prevalent.

The city’s residents are particularly concerned about the increasing rate of muggings and property crimes, and safety at night is a serious issue.

Belo Horizonte’s cultural sector saw a boost with the opening of the Museu das Minas e do Metal, now attracting 25% more visitors than previous years.

However, crime is a persistent issue in Brasília. The homicide rate is 15.8 per 100,000 people, and the overall crime index is moderate at 55.72.

Brasília continues to show signs of resilience, with Brazil’s GDP expected to grow by 2.09% in 2024. This growth is largely driven by the services sector, which accounts for a significant part of the city’s economy.

However, there are concerns about inflation due to fiscal imbalances, which might impact overall stability.

It plays a key role in Brazil’s tourism and services sectors, drawing visitors for its stunning beaches, cultural festivals, and historic landmarks. The city’s strategic location makes it a hub for commerce and trade, further boosting its economy.

However, Fortaleza faces serious crime challenges. With a crime index of 75.67 and a homicide rate of 61 per 100,000 residents, it is considered one of Brazil’s most dangerous cities.

Armed robberies, muggings, and property crimes are common, and safety remains a concern, particularly at night.

Medellín’s economy has expanded, making it a key player in Colombia’s industrial and tourism sectors, with many visitors drawn to its cultural attractions and modern infrastructure.

Although the city has made progress, crime remains a challenge. Medellín’s homicide rate has dropped significantly, reaching 14 per 100,000 people, thanks to various security measures.

However, gang violence, extortion, and armed robbery are still prevalent in certain areas. Organized crime groups, like La Oficina, control parts of the city, and extortion, especially of local businesses, remains an issue.

However, Guayaquil has faced significant challenges with crime, particularly over the last few years. The crime index stands at 74.77, and the homicide rate is 42 per 100,000 people.

Gang violence, extortion, and armed robberies have become increasingly common, largely driven by the rise of organized crime groups linked to the drug trade.

The situation has worsened to the point where a state of emergency was declared in early 2024, following violent attacks and terror incidents involving gangs.

Known for its well-preserved colonial architecture and proximity to the Andes, Quito has a growing economy, driven largely by tourism, commerce, and the service sector.

However, like other major Latin American cities, Quito faces rising crime rates. The city has a crime index of 52, with a homicide rate of 25.9 per 100,000 people.

Certain districts, such as Eloy Alfaro and Eugenio Espejo, report higher crime rates, particularly for car theft and violent robberies.

14. Caracas

Caracas, the capital of Venezuela, remains a significant city in South America, with a population of nearly 3 million in 2024. Despite its ongoing economic struggles, largely influenced by Venezuela’s political instability, Caracas remains an essential hub for trade and services.

The city’s economy is closely tied to the oil sector, but it has seen massive shifts due to the country’s economic crisis.

Caracas is notorious for its high crime rate, with a homicide rate of 53 per 100,000 people and an overall crime index of 84.2. Violence, armed robberies, and kidnappings are common in many parts of the city, making it one of the most dangerous capitals in the world.

However, Maracaibo faces high crime rates, with a homicide rate of 47 per 100,000 and an overall crime index of 78.4.

The city struggles with issues related to violence, theft, and organized crime, which have escalated in recent years due to the country’s political and economic instability.

Although considered one of the safest capitals in South America, Montevideo still faces crime challenges. The city’s crime index is 56.03, with a homicide rate of 7.2 per 100,000 residents.
