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.
Brazilians
Most East Asians, especially Japanese Brazilians, the largest group, live in São Paulo and Paraná. Most Koreans also live in São Paulo whereas the Chinese diaspora is spread particularly throughout the Southeast. Rio de Janeiro has a large Chinese population following São Paulo.The Brazilian Institute of Geography and Statistics (IBGE) classifies the Brazilian population in five categories: "brancos" (white), "negros" (black), "pardos" (brown or mixed), "amarelos" (Asian/yellow) and "índios" (Amerindian), based on skin color or race. The last detailed census (PNAD) found Brazil to be made up of c. 91 million white people (White Brazilian), 79 million multiracial people (Pardo), 14 million black people (Afro-Brazilian), 2-4 million Asian people (Asian Brazilian) and 807,900 indigenous (Amerindian) people.
In the 2005 detailed census, for the first time in two decades, the number of White Brazilians did not exceed 50% of the population. On the other side, the number of "pardos" (multiracial) people increased and all the others remained almost the same. According to the IBGE, this trend is mainly because of the revaluation of the identity of historically discriminated ethnic groups.
