The Afrobarometer is an independent, non-partisan research instrument that measures the social, political and economic atmosphere in Africa. Between 22 April and 10 May 2005, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1,198 Beninois drawn from all 12 of the country’s départments. Face-to-face interviews were conducted by the Institute for Empirical Research in Political Economy (IREEP) in French and eight major local languages spoken by most nationals. 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 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.
