Juba (/ˈdʒuːbə/) is the capital and largest city of South Sudan. The city is situated on the White Nile and also serves as the capital of the Central Equatoria State. It is the world's newest capital city to be elevated as such, and had a population of 525,953 in 2017. It has an area of 52 km2 (20 sq mi), with the metropolitan area covering 336 km2 (130 sq mi). Juba became the world's newest national capital on 9 July 2011, when South Sudan formally declared its independence from the Republic of the Sudan. However, influential parties including the South Sudanese government expressed dissatisfaction with the city's suitability as a national capital, and the government proposed that a new planned city be built as a replacement capital elsewhere, most likely Ramciel in Lakes.
