The urban areas of Rio de Janeiro are dominated by slum districts; so-called favelas. The favelas of Rio de Janerio are lawless environments dominated by poor citizens, unemployment, crime, drugs and weapons. The population in the favelas of Rio de Janeiro has dramatically increased during the last decades due to urbanization and because of the significant economic divide between rich and poor. Data back from 2010 shows that 6% of the population lives in the Brazilian slums.
The favelas of Rio de Janeiro in general and the high crime rates have been a major political issue according to 2014 FIFA World Cup where Brazil is host nation.
