The Diocese of Rumbek covers an area of around 65,000 sq km within Lakes and Warrap States. The township of Rumbek is the capital of Western Lakes State, central South Sudan. It is approximately 377 kilometres (234 mi) by road northwest of Juba, the capital and largest city in the country. Like most South Sudanese towns, Rumbek suffered significant infrastructural damage during the civil war, in which an estimated 2 million people perished. In 2004, the United Nations estimated the population of Rumbek County at about 82,500. At that time, the Dinka Agar constituted about 60% of the population, 30% were Dinka Gok, 6% were Bongo and 45% were Jur-Bel. In 2011, the population of the town of Rumbek was estimated at about 32,100. The town of Rumbek is situated on the main road (A43) from Juba to the southeast to Wau to the northwest. The road network of South Sudan has been severely compromised both by civil strife and adverse weather conditions; the majority of the roads are not paved and all are in poor condition. Rumbek is served by Rumbek Airport.
