Although Rocinha is technically classified as a neighborhood, many still refer to it as a favela. It developed from a shanty town into an urbanized slum. Today, almost all the houses in Rocinha are made from concrete and brick. Some buildings are three and four stories tall and almost all houses have basic sanitation, plumbing, and electricity. Compared to simple shanty towns or slums, Rocinha has a better developed infrastructure and hundreds of businesses. There is also lots of deliquency, crime and drugs in the favelas.
