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.
Social issues in Brazil
Rapid urbanisation and population growth have caused many problems in developing cities. As cities grow too rapidly, resources are not able to keep up with the swelling population. Housing is one of the major problems many developing cities are facing today. Migrants who cannot afford proper housing are forced to build temporary housing without proper utilities. These settlements are known as favelas. With a population of 12.7 million people, Rio de Janeiro is the second largest city in Brazil. With a combination of push and pull factors, urban migration to Rio account for over 65% of population growth. This has led to a serious shortage of proper housing.
