Between May and August 2017, World Bank in collaboration with South Sudan’s National Bureau of Statistics, funded by DfID, conducted the fourth wave of the High Frequency South Sudan Survey to monitor welfare and perceptions of citizens, revisiting urban households visited in Waves 1 and 2. This dataset contains information on security, economic conditions, education, employment, access to services, and perceptions. 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 (2014).
