Liberia Round 4 summary of results

Between 8 December and 21 December 2008, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1200 adult Liberians. Face to face interviews were conducted by Subah-Belleh Associates of Liberia in all 15 of Liberia’s counties. 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 county 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 2008 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. 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 approximately ±3.0 percent at a confidence level of 95 percent.
