In today’s lesson, we explored a case study on population density and distribution in Brazil, the largest country in South America, covering over 5.5 million square kilometers. Brazil has a population density of 22.9 people per square kilometer, indicating uneven population distribution, with 90% of Brazilians living along the coast. The southeastern region, known as the “Golden Triangle,” includes major cities like Rio de Janeiro and São Paulo, which are densely populated due to their favorable climate, fertile soil, and job opportunities. However, these cities also face challenges, including the prevalence of slum areas.
