Johannesburg is a large metropolis and South Africa's largest city. Johannesburg has a population of almost 1 million people in the city, and 4.4 million people in the urban area (2011), half of which live in Soweto and adjacent suburbs. The majority of the population is formed by South Africa's black residents who mostly live in Soweto, while white residents amount to 500,000 (although the number is likely to be higher). There are also around 300,000 residents of other descent, including Africa's largest ethnic Chinese community.
The city is also home to two Chinatowns; the original one on Commissioner Street has shrunk dramatically since its heyday, but still has a few shops and business run by the small community of South African Chinese, while a newer and larger Chinatown in the suburb of Cyrildene is largely populated by immigrants and expatriates from China. Unlike other South African cities, no language group dominates, although English is the established lingua franca.
There are many things that are unique to Johannesburg. It features a distinct street entrepreneurship, and motorists can buy things from vendors selling goods at traffic lights, as in many other developing-world cities. This includes food, umbrellas, soccer balls, cellular phone accessories and many other goods. Barber shops consisting of nothing but a chair and an enthusiastic barber can be found on the sides of roads, although they tend to specialize in African rather than Caucasian hair.
