Coverage
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 other three former states (Jonglei, Unity, and Upper Nile) could not be surveyed due to security concerns.

Sampling
Wave 2 of the High Frequency South Sudan Survey revisited the urban households surveyed in Wave 1. In addition, Wave 2 surveyed five additional enumeration areas in each of the following three states: Northern Bahr el Ghazal, Lakes and Eastern Equatoria and added Warrap state to the sample. Thus, 15 urban enumeration areas were selected in total from each state. For the additional enumeration areas, the same sample design as for Wave 1 was followed after excluding already selected enumeration areas due to the revisit. The design employs a stratified clustered design. Within each of the 7 strata (7 states, urban) the primary sampling units are enumeration areas (EAs) that were drawn randomly proportional to size. Within EAs, a listing was conducted for the new enumeration areas introduced into the sample and 12 households were drawn randomly as unit of observation.
Enumeration Areas (EA) were replaced if security rendered field work unfeasible. Replacements were approved by the project manager. Replacement of households were approved by the supervisor after a total of three unsuccessful visits to the household.
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.
Survey instrument
The questionnaire was coded and administered using SurveyCTO.
Data collection
| Start | End | Cycle |
|---|---|---|
| 2016-02 | 2016-06 | Wave 2 |
The survey was conducted using a CAPI mode (SurveyCTO sofware). Some questions refered to responses of earlier questions in their wordings. To allow that, the questions might have special characters in their wordings.
For example:
Question"Please confirm that your ID number is [qr_id]," where qr_id is another variable. Here the square brackets [] are used so that instead of "qr_id," the value of qr_id as selected by the respondent, will appear within the wordings of this question in the tablet when the survey is administered.
The data tables were downloaded directly from the SurveyCTO platform. Each data table has variables "State", "ea", and "hh". These are the identifying variables for the households and are used to match the observations in the given datasets.
