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.

Owing to the proximity of Rio's port facilities, many of Brazil's export-import companies are headquartered in the city. In Greater Rio, which has one of the highest per capita incomes in Brazil, retail trade is substantial. Many of the most important retail stores are located in the Centre, but others are scattered throughout the commercial areas of the other districts, where shopping centres, supermarkets, and other retail businesses handle a large volume of consumer trade.
