Since the Second Sudanese Civil War in 1983, South Sudan has seen significant levels of displacement driven by conflict, resource stress, climate shocks, and disease. Movement, already an endemic feature of life in South Sudan, has enabled many South Sudanese households or household members to escape or mitigate years of shocks, but those deciding to move have often faced competing needs, physical risks, and constraints on movement. In order to better understand how both displacement routes and displacing households’ decision-making regarding movement has evolved over the past 35 years, REACH conducted research, consisting of secondary data review and quantitative and qualitative analysis, on long-term population movements trends in South Sudan between 1983-2019, to help humanitarians improve their ability to plan for early response in areas likely to receive displacement.
