A pattern emerges of distinct regional groupings, with some spatial variety in and around the former township areas of the province.
In the Gauteng periphery, dominant languages appear to correlate with provincial language prevalence:
Zulu is the most widely spoken language in the periphery of Johannesburg and Ekurhuleni metropoles, while Pedi and Tswana dominate in the periphery of Tshwane.
Xhosa – the prevalent language of the Eastern Cape – is most widely spoken in pockets located along the East-West axis of the Gauteng City Region; an axis largely defined by the mining belt of the Witwatersrand gold reef. This phenomenon may broadly correlate to settlement trends and/or legacies of Xhosa migrant mine workers in Gauteng.
The data paints a picture of Gauteng as a language crossroad between provinces of the Highveld plateau.
