Demographic profile

South Sudan, independent from Sudan since July 2011 after decades of civil war, is one of the world’s poorest countries and ranks among the lowest in many socioeconomic categories. Problems are exacerbated by ongoing tensions with Sudan over oil revenues and land borders, fighting between government forces and rebel groups, and inter-communal violence. Most of the population lives off of farming, while smaller numbers rely on animal husbandry; more than 80% of the populace lives in rural areas. The maternal mortality rate is among the world’s highest for a variety of reasons, including a shortage of health care workers, facilities, and supplies; poor roads and a lack of transport; and cultural beliefs that prevent women from seeking obstetric care. Most women marry and start having children early, giving birth at home with the assistance of traditional birth attendants, who are unable to handle complications.

Educational attainment is extremely poor due to the lack of schools, qualified teachers, and materials. Less than a third of the population is literate (the rate is even lower among women), and half live below the poverty line. Teachers and students are also struggling with the switch from Arabic to English as the language of instruction. Many adults missed out on schooling because of warfare and displacement.

Almost 2 million South Sudanese have sought refuge in neighboring countries since the current conflict began in December 2013. Another 1.96 million South Sudanese are internally displaced as of August 2017. Despite South Sudan’s instability and lack of infrastructure and social services, more than 240,000 people have fled to South Sudan to escape fighting in Sudan.
