Peacebuilding Fund Durable Solution Analysis Survey - Darfur, 2020-2021, IDP returnees, IDPs, non-displaced and nomad profiling in Darfur

Sampling Approach
The sampling followed a stratified multi-stage sampling approach in which villages were the primary sampling unit (PSU) and households were the secondary sampling unit (SSU), while stratification was done by target group. Accordingly, the first sampling stage consisted of selecting a sample of villages with probabilities that were proportional to size; villages with higher numbers of households had a higher probability of being selected for the survey. A random sample of households was then selected based on two approaches: systematic skips or systematic snowballing. This depended on the spatial distribution of the target groups in each
village. For example, in all camps and return villages where only IDPs reside, systematic skips were done. In villages with more target groups, systematic snowballing was performed for each target group.

Sampling limitations & specifications

• The sampling is designed to produce results representative for each target group in the locality. Analysis at the village level is not possible and therefore no reference to villages or breakdown by villages is done in the report.
• The locations targeted for the survey were not selected randomly across the localities and thus do not necessarily provide representative results of all settlement situations in the localities. The targeting of location has been based on a conflict sensitive approach and the programmatic scope of the PBF. However, the area level analysis has looked at locality as a whole and thus ounterbalance the survey scope which focused on the displaced target groups.
