We visited a favela one day while in Rio-pictured above is the one where Michael Jackson filmed his video described.
A favela is the term for slum in Brazil, most often within urban areas. The first favelas appeared in the late 19th century and were built by soldiers who had nowhere to live. Some of the first settlements were called bairros africanos (African neighbourhoods). This was the place where former slaves with no land ownership and no options for work lived. Over the years, many former black slaves moved in.
Even before the first favela came into being, poor citizens were pushed away from the city and forced to live in the far suburbs. However, most modern favelas appeared in the 1970s due to rural exodus, when many people left rural areas of Brazil and moved to cities. Unable to find a place to live, many people ended up in a favela. Census data released in December 2011 by the IBGE (Brazilian Institute of Geography and Statistics) shows that in 2010, about 6 percent of the population lived in slums in Brazil.This means that 11.4 million of the 190 million people that lived in the country resided in areas of irregular occupation definable by lack of public services or urbanization, referred to by the IBGE as “subnormal agglomerations”.
Michael Jackson connected with Rio in 1996 when he shot part of the “They Don’t Care About Us” video in the Santa Marta favela in Botafogo. The event assumed huge significance for the community, as José Mario Hilario dos Santos, president of the Santa Marta residents association, explained; “There are a lot of fans in the community. Everyone loves Michael Jackson and you could always hear his music here. He could have chosen any of the communities and it means a lot that he came here.”
