In May and June 2009, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1200 adult Zimbabwean citizens. Face-to-face interviews were conducted by the Afrobarometer team based at the Mass Public Opinion Institute (MPOI) in the language of the respondent’s choice. 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 district and urban/ 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 most recent census. This ensured that every 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. The gender of respondents was alternated during the interviews to ensure equal gender quota. A sample of this size is sufficient to yield an overall margin of error of approximately ± 3 percent at a confidence level of 95 percent.
