Bolivia, officially the Plurinational State of Bolivia, is a landlocked country of 1,098,581 square kilometres in west-central South America, bordering Brazil to the north and east, Paraguay and Argentina to the south, and Chile and Peru to the west. Sucre is the constitutional capital, while La Paz is the seat of government. The western third is dominated by the Andes: the Cordillera Occidental and Cordillera Oriental enclose the Altiplano, where Lake Titicaca, the Salar de Uyuni and volcanic terrain lie mostly above 3,500 metres. Nevado Sajama reaches 6,542 metres, Bolivia’s highest point. Eastward, the mountains descend through inter-Andean valleys and the humid Yungas into lowlands drained largely toward the Amazon. These include the Beni plains, the Chiquitania and, farther south, the drier Gran Chaco, producing a sharp transition from high mountain plateau to tropical basin.
Altitude is the strongest control on Bolivia’s climate, modifying the effects of tropical latitude and producing marked differences over short distances. The Altiplano is cool to cold, windy and generally semi-arid, with strong daily temperature ranges and a summer rainy season concentrated roughly from November to March; the inter-Andean valleys are milder, while the Yungas and Amazonian lowlands are warmer and much wetter. Southeastern lowlands toward the Chaco are hot and seasonally dry. Moisture carried from the east rises against the Andes, helping explain the contrast between humid eastern slopes and the drier plateau beyond them. El Niño and La Niña episodes can intensify rainfall variability, drought, flooding and agricultural losses. Water security is especially sensitive in the highlands: a World Bank assessment published in 2022 reported that Bolivia had lost about half of its mountain-glacier surface over the preceding 50 years, while floods, landslides, drought and wildfire increasingly affect rural production and expanding cities.
These climatic divisions support ecosystems ranging from Amazon rainforest and cloud forest to high-Andean puna, dry Chiquitano forest, savanna, Pantanal wetlands and Chaco scrub. FAO’s 2020 forest assessment classified about 47 percent of Bolivia’s land area as forest, although deforestation and fire have continued to alter lowland landscapes, especially where ranching and mechanized agriculture expand. Protected areas such as Madidi, Noel Kempff Mercado and Sajama encompass major samples of this ecological range; Noel Kempff Mercado is also a UNESCO World Heritage property. Land use follows the environmental gradient. Potatoes, quinoa, barley, llamas and alpacas characterize highland production, while maize, fruit and vegetables are important in the valleys. Santa Cruz and adjoining eastern lowlands contain the largest commercial farming belt, producing soybeans, sugarcane, sunflower, sorghum and cattle. This eastward agricultural expansion has strengthened Santa Cruz economically but has also made forest conversion, fire management and soil conservation central environmental issues.
Human occupation long predates the modern state, and the southern Lake Titicaca basin became one of the principal centres of pre-Columbian Andean civilization. Tiwanaku developed into a major political and ceremonial centre during the first millennium CE, influencing a broad region before declining around the start of the second millennium. Aymara-speaking polities subsequently dominated much of the Altiplano, and the Inca incorporated the region into Tawantinsuyu in the late fifteenth century. Spanish conquest in the sixteenth century redirected authority and production toward an imperial mining economy. The discovery of rich silver deposits at Cerro Rico in 1545 transformed Potosí into a major urban and commercial centre and tied Charcas to transatlantic finance and regional trade. Colonial extraction relied heavily on coerced Indigenous labour, including the mita, while missions, estates and market towns reshaped lowland and valley societies. Major anti-colonial uprisings in 1780–81, including the siege of La Paz associated with Túpac Katari, exposed deep inequalities. Independence movements began in 1809 and culminated in sovereignty in 1825, when the new republic took the name Bolivia in honour of Simón Bolívar.
The republic inherited fragmented geography, weak internal communications and disputed frontiers. Defeat by Chile in the War of the Pacific of 1879–84 cost Bolivia its Pacific coastline, making access to foreign ports a permanent economic and diplomatic concern. The Chaco War against Paraguay from 1932 to 1935 brought another costly territorial defeat and discredited much of the old political order. Those pressures contributed to the National Revolution of 1952, which introduced universal suffrage, agrarian reform and nationalization of the largest tin mines, greatly expanding political participation. Military governments again dominated after 1964 until elected civilian rule was restored in 1982; severe inflation and fiscal crisis then prompted market reforms from 1985. Conflicts over water, hydrocarbons, land and representation in the early 2000s helped propel Indigenous and popular movements to the centre of national politics. The 2009 constitution redefined Bolivia as a plurinational, decentralized state with autonomies and broader recognition of Indigenous institutions. After the disputed 2019 election and subsequent crisis, elections restored constitutional government in 2020, and the 2025 presidential election produced another transfer of power through the electoral system.
Bolivia’s economy still reflects the long influence of extractive industries, although agriculture, commerce, transport, public services and other services employ far more people than mining or hydrocarbons alone. National statistics show real GDP growth slowing to 0.73 percent in 2024 and a preliminary contraction of 1.58 percent in 2025; petroleum and natural-gas extraction fell sharply in 2025 as mature gas fields declined. Export earnings remain concentrated in minerals and primary or lightly processed commodities. In the first five months of 2025, zinc and silver ores, natural gas, soybean derivatives and metallic gold were among the leading exports by value. Bolivia also has very large lithium resources in the Uyuni, Coipasa and Pastos Grandes salt flats; USGS estimated measured and indicated resources at about 23 million tonnes in 2025, a resource figure that should not be confused with commercially recoverable reserves. The central development problem is therefore not resource scarcity but converting resources into sustained productivity, investment and employment while managing fuel-import costs, foreign-exchange shortages, fiscal pressures, informality and uneven regional development.
The 2024 Population and Housing Census counted 11,365,333 residents, of whom 7,846,708 lived in urban areas and 3,518,625 in rural areas, making Bolivia about 69 percent urban by the census definition. Population is distributed very unevenly. Santa Cruz department, with 3.12 million people, narrowly surpassed La Paz department, with 3.03 million, while Cochabamba had just over 2.01 million; sparsely settled Pando and Beni contain far fewer inhabitants across much larger territories. The principal urban system follows a central axis linking the Santa Cruz metropolitan area, Cochabamba and the adjoining highland cities of La Paz and El Alto. Sucre remains the constitutional capital, while other departmental capitals anchor their regions. Bolivia is organized into nine departments, with lower levels including provinces, municipalities and Indigenous territorial entities. The 2024 census also recorded a demographic transition: 27.0 percent of the population was under 15, 65.6 percent was aged 15–64 and 7.4 percent was 65 or older.
Bolivia’s social geography is multilingual and regionally differentiated rather than reducible to a single ethnic majority. The 2009 constitution recognizes Spanish and 36 named Indigenous languages as official languages of the state. Spanish is the dominant national lingua franca, but Quechua and Aymara remain widely spoken in the Andes and valleys, while Guaraní and numerous smaller languages are associated especially with eastern and lowland peoples. The 2024 census recorded more than one million declarations of self-identification for each of the Quechua and Aymara peoples, with Guaraní and Chiquitano declarations each exceeding 100,000; these categories describe self-identification, not rigid racial divisions. The constitution makes the state independent of religion, although Roman Catholic institutions remain historically influential alongside Protestant communities and Indigenous spiritual traditions. Cultural life reflects these overlapping histories in institutions such as the ayllu, in urban and rural music and literature, and in the architecture of Sucre, Potosí, Tiwanaku and the Jesuit missions of Chiquitos.
Transport and infrastructure are shaped by great distances, steep Andean relief and the absence of a seacoast. Roads carry most domestic passenger and freight traffic; the Administradora Boliviana de Carreteras reported 16,733.68 kilometres in the Red Vial Fundamental for the 2023–24 conservation cycle, linking the main cities and border crossings, although all-season reliability remains weaker in many rural and lowland areas. Rail infrastructure is divided between an Andean network running through Oruro, Uyuni and Villazón and an eastern network centred on Santa Cruz and extending toward Puerto Quijarro on the Brazilian frontier; as of 2026 the two systems were still not connected. Viru Viru, El Alto and Jorge Wilstermann are the principal international airports. Foreign trade therefore depends heavily on overland access to Pacific ports in Chile and Peru, routes into Brazil and Argentina, and the Paraguay–Paraná waterway. Electricity access reached 96.6 percent of the population in 2024 according to World Bank data, while fixed-internet connections reached about 1.44 million by December 2024, with weaker service outside major urban corridors.
Bolivia occupies an important junction between the Andean highlands, the Amazon basin and the La Plata system, and its regional diplomacy reflects that geographic overlap. It remains a member of the Andean Community with Colombia, Ecuador and Peru; in July 2024 it also completed the ratification required to become a MERCOSUR state party, deepening institutional links with the Southern Cone. Landlocked status raises logistics costs, but borders with five countries give Bolivia multiple corridors toward Pacific and Atlantic markets, including the Paraguay–Paraná waterway. Its future regional weight will depend less on any single commodity than on whether it can combine minerals, lithium, agriculture and energy with better transport, more reliable macroeconomic institutions and broader investment. At the same time, wildfire, deforestation, glacier retreat, water stress, urban growth and rural connectivity impose costs that cannot be separated from economic policy. The central structural question is whether Bolivia can turn geographic diversity and resource abundance into sustained, widely distributed productivity without deepening fiscal, environmental or regional imbalances.
