Coverage
The HFS covered urban areas of seven of South Sudan's ten former states: Western Equatoria, Central Equatoria, Eastern Equatoria, Northern Bahr-El-Ghazl, Western Bahr-El-Ghazal, Warrap and Lakes state. The CRS covered four of the largest Protection of Civilian (PoC) camps with defined boundaries: Bentiu, Bor, Juba, and Wau.

Sampling
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.
The CRS was conducted in 4 IDP camps in South Sudan between May to July 2017. The sample was restricted to Protection of Civilian (PoC) camps, and includes the 4 largest camps with clearly defined boundaries. The sample was designed as a multi-stage stratified random sample. Each camp was selected as a strata, with a target of 600 interviews per camp. Within each camp, 50 enumeration areas (EAs) were selected proportional to size, where the size was defined by the number of structures in the EA. The number of structures was counted using satellite imagery of the EAs and strata. Each EA was divided into 12 blocks, and a micro listing was done in the blocks to randomly select households. One structure per block was selected, and one household per structure was interviewed.
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 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.
In the HFS, 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.
In the CRS, the selection probability of an EA is calculated as the number of structures in the EA divided by the number of structures in the stratum multiplied by the number of EAs selected in the stratum. The number of structures was estimated using satellite imagery of the strata (camps). The selection probability of a household within the EA is decomposed into the selection probability of a block within the EA, the selection probability of a structure within a block, and the selection probability of a household within a structure. The sampling weights are then scaled to equal the number of structures per stratum as per the satellite imagery. In the Bor camp, the total number of households was similar to the target sample size, thus a census was conducted -- therefore, each household had a probability of selection of 1 and thus a sampling weight equal to 1.
