situating the Gauteng City-Region
This State of the City-Region Review focuses on the region of towns and cities in and around Gauteng, the smallest, most densely populated and most economically important of South Africa’s nine provinces.
Gauteng is situated in the central north-east of South Africa. The province covers an area of 18179 km2 and is home to over 11 million people. This population is spatially organised in a sprawling region of geographically distinct cities and towns. In this polycentric region the most recognisable cities are Johannesburg and Pretoria, but there are also a number of other significant urban centres. Many of the centres are inside the provincial boundary. Others are outside the administrative space of the Gauteng province but nevertheless closely connected to it in a way that makes up a functionally integrated city-region. The first map below, where each dot represents 1000 people recorded in South Africa’s 2001 census, shows how this extended Gauteng City-Region contains some 13 million people within 175 km of central Johannesburg – over a quarter of South Africa’s total population.
The discovery of gold in the late 1800s kickstarted the rapid growth of the region. Today it is South Africa’s most significant economic space, and by many estimates the largest urban economy on the continent. It plays a vital hub function. Road networks (map 2 below), railways, electricty transmission and distribution lines (map 3 below), and a host of other infrastructural networks, all converge on and radiate out from this key urban region. |
