Located on the banks of the White Nile, Juba is the capital of South Sudan and also the country’s most populous city.

Juba has been the capital of South Sudan since the country formally declared its independence from the Republic of Sudan on the 9th of July, 2011. Ever since, there has been an ongoing discussion about creating a new capital city somewhere else in the country; a city that would be more well-planned than Juba and also more centrally located. So far, these plans have not come into frutition and Juba continues to be the country’s capital.

Juba grew out of a trading station and Christian mission founded along the White Nile in the 19th century, and was an important river port for much of the 20th century as well, being the southern terminus of traffic along the river. Before the civil war, Juba was also an inportant hub for land transportation, since highways connected the city to Uganda, Kenya and (what’s today named) the Democratic Republic of Congo. The civil war largely destroyed these connections.

When the last uncontested census was carried out in 1993, it reported a population of 114,980. Since then, all population numbers have been based on estimates. In 2006, the population was estimated to be around 250,000 based on aerial photos. The growth of the oil industry, coupled with Chinese investments, has boosted the growth of the young capital, and in 2014 the population was estimated at nearly half a million, with a lot of residents being recent arrivals from the Republic of Sudan or other parts of Eastern Africa.
