Paraguay, officially the Republic of Paraguay, is a landlocked country in central South America, bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. Paraguay lies on both banks of the Paraguay River, which runs through the center of the country from north to south. Due to its central location in South America, it is sometimes referred to as Corazón de Sudamérica ("Heart of South America"). Paraguay is one of the 2 landlocked countries (the other is Bolivia) outside Afro-Eurasia, and is the smallest landlocked country in the Americas.
As of 2016, Paraguay's population was estimated to be at around 6.7 million, most of whom are concentrated in the southeast region of the country. The capital and largest city is Asunción, whose metropolitan area is home to nearly a 3rd of Paraguay's population. In contrast to most Latin American nations, Paraguay's indigenous language and culture, Guaraní, remains highly influential. In each census, residents predominantly identify as mestizo, reflecting years of intermarriage among the different ethnic groups. Guaraní is recognized as an official language alongside Spanish, and both languages are widely spoken in the country.
