In Brazil, squatter communities are called favelas, and a famous example is Rocinha in Rio de Janeiro, home to up to 180,000 people. Favelas are mostly inhabited by the poorest strata of society, and usually lack much infrastructure and public services, but in some cases, already have reached the structure needed for a city. They are equivalent to slums or shanty towns, and typically occupy unused land (instead of unused or abandoned buildings). There were 25 million people living in favelas across Brazil, as of 2004. After failed attempts in the 1960s and 1970s to bulldoze slums out of existence, the authorities moved towards a policy of toleration.
