Brazil occupies 8,509,360.850 square kilometres according to the IBGE territorial calculation published in March 2026, making it by far the largest country in South America and accounting for nearly half of the continent’s land area. Its land frontier reaches every South American country except Chile and Ecuador: Uruguay, Argentina, Paraguay, Bolivia, Peru, Colombia, Venezuela, Guyana, Suriname and France through French Guiana. The Atlantic forms the entire eastern maritime boundary. Brasília, on the central Brazilian Plateau, is the federal capital. The country’s physical structure is dominated by the vast Amazon lowlands in the north, the older Brazilian and Guiana highlands, the seasonally flooded Pantanal in the west, and coastal ranges and plateaus descending toward the Atlantic. Three immense drainage systems—the Amazon, Paraná-Paraguay and São Francisco basins—organize much of the interior. This continental scale creates strong contrasts between sparsely populated rainforest, agricultural plateaus, semi-arid interiors and densely urbanized southeastern and coastal corridors.
Climate varies sharply with latitude, altitude and continental position. Much of the Amazon is equatorial, with high temperatures and abundant rainfall through most of the year, while central Brazil has a tropical seasonal regime with a pronounced austral-winter dry season. The Sertão of the Northeast is semi-arid, with irregular rainfall often below 800 millimetres annually and recurrent drought risk. Higher parts of the Southeast are cooler, and the South has humid subtropical conditions, stronger seasonal temperature variation and occasional frost. Rainfall commonly exceeds 2,000 millimetres in large parts of the Amazon. These climatic divisions shape farming calendars, hydropower availability, wildfire risk and water security. Recent extremes have demonstrated the country’s exposure: severe flooding affected Rio Grande do Sul in 2024, while drought and fire stressed parts of the Amazon and Pantanal. Longer-term pressures include warming, altered rainfall patterns, erosion, urban flood exposure and competition over water in seasonally dry regions.
Brazil’s six officially recognized terrestrial biomes are the Amazon, Cerrado, Atlantic Forest, Caatinga, Pampa and Pantanal, alongside a vast coastal-marine system. The Amazon covers roughly half the national territory and contains the largest continuous block of tropical rainforest on Earth; the Cerrado, a highly biodiverse tropical savanna, occupies much of the central plateau and is also a principal agricultural frontier. The Atlantic Forest follows much of the densely settled east, while the Caatinga is adapted to the semi-arid Northeast, the Pampa occupies the far south, and the Pantanal forms an immense seasonal wetland in the upper Paraguay basin. Soybeans, maize, sugarcane, coffee, cattle and commercial forestry are major land uses, but their geography differs strongly by region. Expansion of mechanized agriculture in the Cerrado and southern Amazon has brought export growth alongside habitat loss. INPE’s consolidated PRODES data recorded 5,731 square kilometres of Amazon deforestation in 2025, down from the previous year but still environmentally significant.
Human occupation long predates Portuguese colonization. Archaeological evidence from Amazonia, the Atlantic coast and the central interior shows that Indigenous societies developed diverse systems of agriculture, fishing, forest management, earthworks and regional exchange before Europeans arrived. Large linguistic families such as Tupi, Macro-Jê, Arawak and Carib encompassed many distinct peoples rather than a single political or cultural unit. Portuguese contact began in 1500, and early extraction focused on brazilwood before sugar plantations transformed the northeastern coast in the sixteenth and seventeenth centuries. Colonial production depended heavily on enslaved African labour, while disease, warfare, forced relocation and enslavement devastated many Indigenous communities. Dutch forces briefly controlled parts of the Northeast in the seventeenth century, but Portugal restored its authority. From the late seventeenth century, expeditions from São Paulo pushed settlement and slave-raiding inland; discoveries of gold and diamonds in Minas Gerais and neighbouring areas then shifted economic gravity southward and stimulated internal migration. Rio de Janeiro became the colonial capital in 1763, reflecting the growing importance of mining and Atlantic trade.
The decisive break with the colonial order came after the Portuguese royal court transferred to Rio de Janeiro in 1808 during the Napoleonic Wars, opening ports and elevating Brazil’s administrative importance within the Portuguese monarchy. Independence was declared in 1822, but the new state remained a constitutional empire under the Braganza dynasty until 1889. Territorial consolidation, plantation agriculture and coffee expansion coexisted with slavery until abolition in 1888, making emancipation central to the country’s social history and labour transition. The republic that followed passed through oligarchic rule, the centralizing Vargas era from 1930, rapid industrialization and large-scale urban migration. Brasília was inaugurated in 1960 to shift federal administration inland and support territorial integration. A military regime governed from 1964 to 1985, combining infrastructure expansion and industrial growth with political repression. Civilian rule returned gradually, and the 1988 Constitution established the current democratic framework, strengthened federalism and social rights, and recognized important Indigenous territorial rights. Brazil today is a federal presidential republic composed of states, municipalities and the Federal District.
Brazil has a diversified economy in which services dominate output, but agriculture, mining, manufacturing and energy remain unusually important for exports and regional development. IBGE reported real GDP growth of 2.3% in 2025, when agriculture expanded strongly after a weaker 2024, while services and industry also grew. The country is a major producer of soybeans, maize, coffee, sugar, beef and poultry, while iron ore and offshore petroleum—especially from the pre-salt basins—anchor extractive exports. Manufacturing includes food processing, steel, chemicals, vehicles, machinery and aircraft, with São Paulo and the broader Southeast still the principal industrial concentration. China is by far the largest market for Brazilian goods, while the United States, Argentina and the European Union remain important partners. Strong commodity earnings coexist with infrastructure bottlenecks, high financing costs, regional inequality and uneven productivity. Labour-market conditions improved in 2025, when annual unemployment fell to 5.6%, although 38.1% of employed people were still in informal work.
The 2022 census counted 203,080,756 residents, while the latest annual IBGE estimate available places the population at 213,421,037 on 1 July 2025. Settlement is highly uneven: vast areas of the Amazon and interior remain thinly populated, whereas the Southeast, parts of the South, the northeastern coast and major state capitals contain dense urban networks. The 2022 census classified 87.4% of residents as urban, the outcome of decades of industrialization, rural-to-urban migration and metropolitan growth. São Paulo is the largest city and economic centre; Rio de Janeiro remains a major cultural, service and port metropolis, while Brasília, Belo Horizonte, Salvador, Fortaleza, Recife, Curitiba, Porto Alegre, Manaus and Belém anchor regional systems. Administratively, Brazil consists of 26 states and the Federal District, grouped by the IBGE into North, Northeast, Southeast, South and Centre-West regions. Internal migration has repeatedly reshaped this geography, first toward industrial cities and later toward agricultural, mining and construction frontiers in the Centre-West and North.
Portuguese is the official and overwhelmingly dominant language, but Brazilian society is linguistically and culturally more plural than that suggests. The 2022 census identified 391 Indigenous ethnicities, peoples or groups and 295 Indigenous languages, reflecting continued diversity despite centuries of displacement and assimilation pressure. Immigration also left durable cultural communities associated with Italian, German, Japanese, Arab, Eastern European and other diasporas, especially in the South and Southeast. Religious affiliation has changed substantially: preliminary 2022 census sample results for people aged ten or over put Roman Catholics at 56.7% and Evangelicals at 26.9%, alongside people with no religion, Spiritists, Afro-Brazilian traditions such as Candomblé and Umbanda, and smaller Jewish, Muslim, Buddhist and other communities. Brazilian culture developed through sustained interaction among Indigenous, African, European and later immigrant traditions. Its major forms range from samba, choro and bossa nova to capoeira, modernist literature and the architecture of Brasília, while regional traditions remain strongly differentiated.
Transport reflects both continental scale and historical concentration along the Atlantic-facing economy. Roads carry most passenger and domestic freight movement; in 2025 the DNIT directly administered about 50,654 kilometres of paved federal highways, while major additional routes operate under concessions or state control. Railways are far more freight-oriented: ANTT reported 30,684 kilometres of operational concession railways in 2025, heavily used for iron ore, grain and other bulk commodities. Ports are critical to the export economy. Brazilian ports handled about 1.4 billion tonnes of cargo in 2025, with Santos the principal diversified gateway and Paranaguá, Itaqui, Itaguaí and Rio Grande central to commodity flows; northern terminals increasingly serve the agricultural frontier. Airports connect distant metropolitan centres, while rivers remain indispensable in Amazonia. Electricity is comparatively low-carbon: renewables supplied 88.2% of electricity in 2024, with hydropower dominant and wind and solar together providing 23.7% of generation, although transmission and service quality still vary regionally.
Brazil’s scale gives it unusual weight in South America and in global debates over food, energy, climate and development. It is the largest economy and most populous country in Latin America, a founding member of Mercosur, a member of BRICS and the G20, and the central territorial power in the Amazon Cooperation Treaty Organization. Its borders connect the Atlantic economy with nearly every part of continental South America, while its ports channel mineral, agricultural and energy exports to global markets. The Amazon makes domestic land-use policy globally consequential, and the hosting of COP30 in Belém in 2025 reinforced Brazil’s climate diplomacy. The country must nevertheless reconcile commodity expansion, infrastructure and energy production with forest protection, Indigenous rights and emissions goals. Its medium-term position also depends on raising productivity, reducing persistent social and regional inequality, adapting cities and agriculture to climate extremes, and improving logistics without accelerating ecological degradation. Brazil’s international importance rests on how effectively it manages these interlocking continental-scale pressures.
