Between May and August 2017 The World Bank in collaboration with South Sudan’s National Bureau of Statistics, funded by DfID, conducted the fourth wave of the High Frequency Survey and the Crisis Recovery Survey to monitor welfare and perceptions of citizens in accessible urban areas and IDP camps across South Sudan. The HFS and CRS data contains information on security, economic conditions, education, employment, access to services, and perceptions. The data combines detailed household questionnaire information with displacement-specific information including drivers of displacement, access to resettlement mechanisms, and return intentions. It also includes comprehensive information on assets and consumption, to allow estimation of poverty based on the Rapid Consumption methodology as detailed in Pape and Mistiaen (2015).
