The Afrobarometer National Partner in Sudan, Sudan Polling Statistics Center (SPSC), interviewed a nationally representative, random, stratified probability sample of 1,800 adults in February-April 2021. A sample of this size yields country-level results with a margin of error of +/-2.3 percentage points at a 95% confidence level. Previous surveys were conducted in Sudan in 2013, 2015, and 2018. IDS provided technical backstopping for the survey. Technical details of the survey, including descriptions of stratification and household selection, translation languages, and related information, can be found in the survey Technical Information Form that follows. Below is an outline of the survey findings from all the questions posed to respondents. We also present the findings by some critical demographics such as gender and place of residence (urban-rural).
