Through mobility tracking, DTM is able to provide a comprehensive baseline and regular updates on the trends and changes in numbers, locations and priority needs of IDPs and returnees in South Sudan. In this pilot round, the IOM DTM team covered a total of 93 payams in 23 counties across six states. Locations were chosen to be assessed based on preliminary findings indicating the presence of IDPs and / or returnees and taking into account access considerations. Findings indicate that return movements are on the rise and that the number of new instances of displacement is decreasing (94% displaced before July 2017), whilst many individuals find themselves in protracted displacement situations. Assessed populations report a lack of security, food, shelter and water. Returnee populations additionally report housing land and property issues. Partial or severely damaged housing is reported for 71 per cent of the returnees in the assessed areas.
