Bolivia is a landlocked country located in western-central South America. The capital is Sucre while the seat of government and financial center is located in La Paz. The largest city and principal industrial center is Santa Cruz de la Sierra, located on the Llanos Orientales (tropical lowlands), a mostly flat region in the east of the country.
The sovereign state of Bolivia is a constitutionally unitary state, divided into nine departments. Its geography varies from the peaks of the Andes in the West, to the Eastern Lowlands, situated within the Amazon Basin. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, and to the northwest by Peru. One-third of the country is within the Andean mountain range. With 1,098,581 km2 of area, Bolivia is the fifth largest country in South America, after Brazil, Argentina, Peru and Colombia.
The geography of the country exhibits a great variety of terrain and climates. Bolivia has a high level of biodiversity, considered one of the greatest in the world, as well as several ecoregions with ecological sub-units such as the Altiplano, tropical rainforests (including Amazon rainforest), dry valleys, and the Chiquitania, which is a tropical savanna. These areas feature enormous variations in altitude, from an elevation of 6,542 metres above sea level in Nevado Sajama to nearly 70 metres along the Paraguay River. Although a country of great geographic diversity, Bolivia has remained a landlocked country since the War of the Pacific. Puerto Suárez, San Matías and Puerto Quijarro are located in the Bolivian Pantanal.
The country’s population, estimated at 11 million, is multiethnic, including Amerindians, Mestizos, Europeans, Asians and Africans. The racial and social segregation that arose from Spanish colonialism has continued to the modern era. Spanish is the official and predominant language, although 36 indigenous languages also have official status, of which the most commonly spoken are Guarani, Aymara and Quechua languages.
