Southeast Brazil in the context of "GDP per capita"

Old Tupi, Ancient Tupi or Classical Tupi (Portuguese pronunciation: [tuˈpi]) is a classical Tupian language which was spoken by the indigenous Tupi people of Brazil, mostly those who inhabited coastal regions in South and Southeast Brazil. In the words of Brazilian tupinologist Eduardo Navarro, "it is the classical indigenous language of Brazil, and the one which had the utmost importance to the cultural and spiritual formation of the country".

Old Tupi belongs to the Tupi–Guarani language family, and has a written history spanning the 16th, 17th, and early 18th centuries. In the early colonial period, Tupi was used as a lingua franca throughout Brazil by Europeans and Amerindians, and had literary usage, but it was later suppressed almost to extinction. Today, its sole living descendant is the Nheengatu language.

Guanabara Bay (Portuguese: baía de Guanabara, baía da Guanabara, IPA: [baˈi.ɐ da ɡwɐnaˈbaɾɐ]) is an oceanic bay in Southeast Brazil in the state of Rio de Janeiro. On its western shore lie the cities of Rio de Janeiro and Duque de Caxias, and on its eastern shore are the cities of Niterói and São Gonçalo. Four other municipalities surround the bay's shores. Guanabara Bay is the second largest bay in area in Brazil (after the All Saints' Bay), at 412 square kilometres (159 sq mi), with a perimeter of 143 kilometres (89 mi).

Guanabara Bay is 31 kilometres (19 mi) long and 28 kilometres (17 mi) wide at its maximum. Its 1.5 kilometres (0.93 mi) wide mouth is flanked at the eastern tip by the Pico do Papagaio (Parrot's Peak) and the western tip by Pão de Açúcar (Sugar Loaf).
