This is Wave 4 of the survey. Data collection dates were as follows:
- Wave 1: February - September 2015
- Wave 2: February - June 2016
- Wave 3: September 2016 - March 2017
- Wave 4: May - August 2017
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).

Wave 4 of the High Frequency South Sudan Survey revisited urban households interviewed in Waves 1 and 2. Fifteen urban enumeration areas (EAs) visited in the first two waves were randomly selected from each state, and all of the households interviewed in the selected EAs were to be revisited.
In Waves 1 and 2, the sampling strategy consisted of a stratified clustered design. Within each of the 7 strata (7 states, urban and rural) the primary sampling units are EAs that were drawn randomly proportional to size. Within EAs, a listing was conducted and 12 households were drawn randomly as unit of observation.
Deviations from the Sample Design
EAs were replaced if security rendered field work unfeasible. Replacements were approved by the project manager. Households were not replaced and were dropped from the sample after a total of three unsuccessful visits.
The sampling weight is the inverse probability of selection. The selection probability for a household can be decomposed into the selection probability of the EA and the selection probability of the household within the EA. The selection probability of an EA is calculated as the number of households within the EA divided by the number of households within the stratum multiplied by the number of selected EAs in the stratum estimated using the 2008 Census. The selection probability for a household within an EA is constant across households and is calculated as the number of households selected in the EA over the number of listed households in the EA. Sampling weights were then scaled to equal the number of households per strata using the Census 2008 data.
