In South Africa, squatters tend to live in informal settlements or squatter camps on the outskirts of the larger cities, often but not always near townships. In the mid-1990s, an estimated 7.7 million South Africans lived in informal settlements: a fifth of the country's population. The figure was estimated to be 15 million in 2004. In Cape Town and Durban, there have been sustained conflict between the city council and a shack dwellers' movement known as Abahlali baseMjondolo. The organisation has represented the squatters in land occupations such as the Macassar Village in 2009 and the Cape Town and Durban Marikana land occupations in 2013 (both named after the Marikana massacre). It also successfully challenged the KZN Slums Act, which sought to mandate the eviction of slums but was eventually declared unconstitutional.
