Such slums are common in South Africa, usually within a short drive from city center. Usually segregated, with origins in apartheid era.

South Africa has always been one of the most unequal countries in the world. This extreme inequality, until the end of the apartheid regime, had a unique and particularly pronounced racial dimension. From 1917 to the end of the 1980s, the ruling White minority earned on average more than 10 times the average income of the Black majority.

Today, the transition to democracy did provide new economic opportunities for the underprivileged non-White majority. However, these opportunities have been restricted to a narrow group of the top 10% of Black, Asian, and Coloured earners while that of the poorest 90% of all groups stagnated or even declined. In other words, the economic growth of the recent decades has benefitted to a new multiracial elite, while leaving behind the majority of the poor.
