Between 15 and 31 December 2008, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1232 adult Malians. Face-to-face interviews were conducted by the Research Group in Theoretical and Applied Economics (Groupe de Recherche en Économie Appliquée et Théorique, GREAT) in all 8 of Mali’s Regions and Bamako, reaching both urban and rural areas. 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 administrative region and urban or rural status. 154 EA’s were then randomly selected from these lists with the probability proportionate to its size in the overall population as represented in the 1998 Census. This ensures that every eligible adult had an equal and known chance of being selected. Eight households were then randomly selected within each EA, and a respondent 18 years of age or older was randomly selected from each household. A gender quota ensured that every other interview must be with a female. A sample of this size is sufficient to yield an overall margin of error of +/- 3 percent at a confidence level of 95 percent.
