Since we are a SEO Johannesburg company, I though it might be worthwhile to share some more information on the City of Gold here.
Johannesburg (/dʒoʊˈhænᵻsbɜːrɡ/; Afrikaans: [joˈɦɐnəsbœrχ]; also known as Jozi, Jo’burg, Joni, eGoli, and abbreviated as JHB) is a large metropolis and the largest city in South Africa. It is the provincial capital of Gauteng, which is the wealthiest province in South Africa. The city is one of the 50 largest urban agglomerations in the world. The city was named and established in 1886 following the discovery of gold on what had been a farm. The city is commonly interpreted as the modern day El Dorado due to the extremely large gold deposit found along the Witwatersrand. The name is attributed to one or all of three men involved in the establishment of the city. In ten years, the population was 100,000 inhabitants. While Johannesburg is not one of South Africa’s three capital cities, it is the seat of the Constitutional Court, which has the final word on interpretation of South Africa’s constitution as well as with issues in connection with constitutional matters. The city is the source of a large-scale gold and diamond trade, due to its location on the mineral-rich Witwatersrand range of hills.
In 2011, the population of the city of Johannesburg was 4,434,827, making it the largest city in South Africa. In the same year, the population of Greater Johannesburg Metropolitan Area was 7,860,781. Some view the area surrounding the city of Johannesburg yet more broadly than the metropolitan area, adding Ekurhuleni, West Rand and Lenasia; that larger area had a population of 10,267,700 in 2007. The land area of the municipal city 1,645 km2 (635 sq mi) is large in comparison with those of other major cities, resulting in a moderate population density of 2,364/km2 (6,120/sq mi).
A separate city from the late 1970s until the 1990s, Soweto is now part of Johannesburg. Originally an acronym for “South-Western Townships”, Soweto originated as a collection of settlements on the outskirts of Johannesburg, populated mostly by native African workers from the gold mining industry. Soweto, although eventually incorporated into Johannesburg, had been separated as a residential area for blacks, who were not permitted to live in Johannesburg proper. Lenasia is predominantly populated by English-speaking South Africans of Indian descent.
