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
Rio has maintained its status as the second largest manufacturing centre in Brazil, after São Paulo. In addition, Rio's service sector remains one of the strongest in the country, providing for increasing numbers of jobs in such areas as finance, communications, tourism and entertainment, public and private education, and computer engineering. Rio remains a major centre for cultural exhibitions and international conferences, and many of the more affluent and influential Brazilians keep homes there. Despite desperate conditions in the favelas, as well as high rates of violent crime throughout the city, grave levels of air and water pollution, and myriad other problems, Rio de Janeiro is still widely recognized as one of the world's most beautiful city.
