Between 26 September and 8 October 2005, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1200 Senegalese. Face-to-face interviews were conducted by the Afrobarometer team based at GERCOP l’ENEA at L’Universite Gaston Berger de Saint Louis in French, Wolof and Pular across all 11 regions of the country. The sample was drawn by taking the smallest geographic units, census Enumeration Areas (EA’s), and stratifying all EA’s across the country into separate lists according to region and urban or rural status. 150 EA’s were then randomly selected from these lists with the probability proportionate to its size in the overall population as represented in the 2002 census. This ensured that every eligible adult had an equal and known chance of being selected. Eight households were then randomly selected within each EA, and one respondent of 18 years of age or older was randomly selected from each household. Sampling procedures ensured that a 50:50 male-to-female ratio was achieved by having every other interview done with a woman. A sample of this size is sufficient to yield an overall margin of error of +/- 3 percent at a confidence level of 95 percent.
