Suburbs of Johannesburg

A map of Johannesburg indicating regions and freeways.

The suburbs of Johannesburg are officially[citation needed] demarcated areas within the City of Johannesburg Metropolitan Municipality, South Africa. As in other Commonwealth countries, the term suburb refers to a "neighbourhood", although in South Africa most (but not all) "suburbs" have legally recognised borders (see legal definition of township) and often (but not always) separate postal codes. The municipal functions for the area, such as municipal policing and social services, are still managed by the city government.

Johannesburg, like many other boom towns, grew rapidly and with little planning, and thus the city covers an extremely large area. The main differences between the city's suburbs tend to be socioeconomic: The north is often associated with wealth due to areas such as Houghton, which boasts large properties and contained the residence of former president Nelson Mandela, and Sandton which has become an alternative business district and is referred to as "Africa's richest square mile".
