South America is the southern portion of the Americas. It ranks among the most peaceful continents in the world, as it has experienced no armed conflict since the dawn of the 21st century. The continent touches the Pacific Ocean in the west, the Atlantic Ocean in the east and north, and the Caribbean Sea to the northwest.

Population Trends in South America 

According to estimations made by the United Nations Department of Economic and Social Affairs Population Division, South America had a population of more than 434 million in 2021. This number is lower than the population of certain individual countries, namely India and China, which have a higher population than the entire South American region. The region has an area of 17,840,000 sq. kilometers, which is 6,890,000 sq. miles. That makes it the fourth largest continent in the world in terms of area, right after Asia, Africa, and North America. When viewed in terms of population, South America is the fifth most populated continent in the world after Asia, Africa, Europe, and North America. The latest statistics by the United Nations Population Division reveal that South America’s population comes up to 5.47% of the total world population.

According to data by the World Bank, Latin America and the Caribbean had a 0.7% annual growth rate in 2022. This rate has been decreasing since 2014, going from 1.1% in 2014 to 1% in 2015 and 0.9% in 2018. South America has only 12 sovereign countries, notably less as compared to other continents. Brazil alone takes over more than half of the region’s area, which also makes it the most populated country in the region. According to a study by Luis L Schenoni, Brazil’s control over South America’s material power has increased from one-third to one-half since the end of the 20th century. Despite that, around 44,000 Brazilians were internally displaced in 2022 because of disasters. This number was the highest in the region, standing next to Colombia’s 41,000 internally displaced individuals by the end of 2022.   

Another report by the Population Reference Bureau showed that 68% of South America’s population stood between the 15-64 age group, with 22% of the population below the 15-year limit. People aged 65 or older made 10% of the population in mid-2023. The highest fertility rate in the region was reported in Bolivia, with 2.5 lifetime births per woman. On the other hand, South American countries with the lowest fertility rates were Chile and Uruguay, with 1.2 and 1.5 lifetime births per woman, respectively. 

Economic Outlook of South American Countries 

According to a report by the World Bank, Latin America and the Caribbean have demonstrated extraordinary economic resilience over the past 30 years. The region has mitigated unprecedented hindrances like global uncertainty, rising debt, increasing inflation, and reduced commodity prices. Such efforts have bolstered its return to pre-pandemic employment levels. 

The report predicts that the region’s Gross Domestic Product (GDP) will increase by 2.3% in 2024 and 2.6% in 2025. Regional growth in the region was 0.7% higher in 2023, primarily because of the boosted economic outputs of the two major economies in Latin America and the Caribbean: Brazil and Mexico. Brazil underwent this increase because of better than expected outcomes in private consumption, agricultural production, and exports in the first three quarters of 2023. In contrast, Mexico saw an improvement in investment growth and private consumption, leading to its better-than-expected output. 

Key Players in the South American Economy 

South America boasts some exceptional companies driving its economy, of which MercadoLibre, Inc. (NASDAQ:MELI), Vale S.A. (NYSE:VALE), and Petróleo Brasileiro S.A. – Petrobras (NYSE:PBR) are a few. Let’s take a look at these companies. 

MercadoLibre, Inc. (NASDAQ:MELI), famously called the “eBay of Latin America,” is an e-commerce platform operational since 1999. This online marketplace connects sellers with buyers, allowing people to undertake seamless online transactions. Based in Argentina, it operates in several countries including Chile, Brazil, and also Mexico in North America. MercadoLibre, Inc.

The additional investment will go into warehouse expansion, technology and marketing investment, loan payments, and improvement of the logistics network. 

Another prominent company in the South American economy is Vale S.A. (NYSE:VALE), a multinational mining company centered in Brazil. Vale S.A. (NYSE:VALE) is widely regarded as the largest company in Latin America, and has been around for more than seven decades. Since its inception as a primarily iron ore extraction company, Vale S.A. (NYSE:VALE) has expanded its functioning to the production and export of copper, iron ore, nickel, coal, and other minerals. As the lead regulator of Latin America’s mining industry, the company has announced its goal to use 100% renewable energy for all its operations by 2030. The company owns the Sol do Cerrado solar panel project, which supplies 16% of the total energy consumed by the company in Brazil while working at its maximum capacity of 766MW. Ludmila Nascimento, Vale’s energy and decarbonisation director, said that the project is contributing to their “goal of being leaders in sustainable mining.”

Petróleo Brasileiro S.A. – Petrobras (NYSE:PBR) is another South American company at the forefront of innovation. The company began its operations in 1953 as an oil and gas company owned by the Brazilian state. It has since then developed into a multi-faceted organization involved in the production, refining, distribution, and extensive exploration of petroleum-related products. Petróleo Brasileiro S.A. – Petrobras (NYSE:PBR) has placed Brazil in the lead in the global oil and gas industry. On March 7, Petróleo Brasileiro S.A. – Petrobras (NYSE:PBR) released its Q4 2023 earnings. The company reported a revenue of $25.27 billion and outperformed estimates by $15.53 million. The company reported an EPS of $0.85 and outperformed EPS expectations by $0.02. Here is what the company’s Financial Director, Sergio Caetano, had to say during the company’s Q4 2023 earnings call

“We added value to the company in the amount of BRL150 billion and compensation to shareholders 20.4 billion with 19.7 billion in dividends and $0.7 billion in the repurchase of shares. To society, we paid between taxes and governmental shares, BRL240 billion, BRL36.6 billion of all dividends paid by Petrobras went to the controlling group that’s comprised by the federal government.

We also contributed another BRL54 billion in the valuation of the public assets of the state. So, in addition to adding value, that was also an important collaboration with society in terms of reverting these resources to taxes and dividends. These are some more data in terms of our financial earnings. An EBITDA of 52.4 billion is the second biggest in history. The operational cash flow, 43.2 billion, the second biggest in history. A free cash flow, $31.1 billion, the third biggest in history. A net revenue, a net profit of 24.9 billion, the second biggest in history. And these numbers, the second highest and third highest, they were produced in a very adverse external environment. So we achieved second and third place with a special highlight. 

Another important aspect when it comes to our financial debt of 28.8 billion, with a reduction of $1.2 billion this year. Return on capital employed 11.2%, which is in line with the previous results. We also brought about the lowest difference vis-à-vis, the American bond to the market. And with that, we won an award, the Quasi-Sovereign Bond Deal of the Year award by issuing $1.5 billion in 10-year bonds”.
