In Recife, the state capital of Pernambuco in the northeast of the country, 193 favelas were listed in 1985, which meant that half the population of city was squatting. In São Paulo, until 1972 favelas were usually demolished then afterwards they were permitted, meaning that in the next decade the number of squatters rose to one million. The largest favela is Heliópolis, with over 200,000 inhabitants as of 2018. It has been officially recognized as a regular neighborhood of the city. There are also a number of squatter buildings in the inner city, the most famous of which was a 22-storey building called Prestes Maia, whose inhabitants were ordered to leave in 2006. The former Hotel Santos Dumont on Mauá Street in the Luz neighbourhood was occupied in 2007 after being derelict for 17 years. An estimated 1,000 people were living in the building, paying a small amount every month to cover maintenance. The community expels people who fight, use drugs or abuse alcohol. Inspired both by this movement and increasing property speculation and gentrification, various occupations in buildings and unoccupied areas in big cities, led by groups such as the Homeless Workers' Movement (MTST) or Downtown Roofless Movement (MSTC).
