Argentina, officially the Argentine Republic (Spanish: República Argentina, Spanish pronunciation:, is a country in South America, constituted as a federation of twenty-three provinces and an autonomous city. It is second in size in South America and eighth in the world. Argentina occupies a continental surface area of 2,766,890 km² (1,068,302 sq mi) between the Andes mountain range in the west and the southern Atlantic Ocean in the east and south. It is bordered by Paraguay and Bolivia in the north, Brazil and Uruguay in the northeast, and Chile in the west and south. Argentina also claimed 969,464 km² (374,312 sq mi) of Antarctica, known as Argentine Antarctica, overlapping other claims made by Chile (Chilean Antarctic Territory) and the United Kingdom (British Antarctic Territory), but all such claims are suspended by the Antarctic Treaty of 1957.
Argentina has the highest Human Development Index level and the second highest Gross Domestic Product (GDP) per capita in purchasing power parity in Latin America. Argentina's nominal GDP is the 31st largest in the world; when purchasing power is taken into account, however, its total GDP makes it the 23rd largest economy in the world.
