Rio de Janeiro
Rio has more people living in slums than any other city in Brazil, according to the 2010 Census. More than 1,500,000 people live in its 763 favelas, 22% of Rio's total population. São Paulo, the largest city in Brazil, has more favelas (1,020) in sheer numbers, but proportionally has fewer people living in favelas than Rio.
History of Rio de Janeiro
Coffee production and the transfer of the Portuguese Court to Brazil in 1808 again brought prosperity to the colony. By 1815, when Brazil became a kingdom, Rio de Janeiro was large enough to accommodate a foreign population. At about that time the city's original appearance was being transformed; from 1808 to 1818 some 600 houses and 100 country houses were built and older buildings were restored. Many streets were lighted and paved, more land was reclaimed, new roads were opened, and new public fountains were installed. Among new institutions established were the Royal Press, the Royal Library, the Theatre of Saint John, the Academy of Fine Arts, the Botanical Garden, and the Bank of Brazil. When King John VI returned to Portugal in 1821, Rio had almost 113,000 inhabitants and 13,500 buildings, and the town had extended both northward and southward. A year later Brazil was independent.
