In December 2011, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1,200 Cape Verdeans. Face-to-face interviews were conducted by the Afrobarometer team based at Afro-Sondagem. 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 (island) and urban or rural status. 150 EAs were then randomly selected from these lists with the probability proportionate to its size in the overall population as represented in 2010 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.
