Zambia Round 3 summary of results

In July/August 2005, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1200 Zambians. Face to face interviews were conducted by the Afrobarometer across all 9 provinces. Fieldwork was conducted by Steadman Research Services International, Ltd. The sample was drawn by taking the smallest geographic units, census Enumeration Areas (EA’s), and stratifying all these across the country into separate lists according to province and urban/ rural status. One hundred fifty EA’s were then randomly selected from these lists with the probability proportionate to size in the overall population as represented in the 2001 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 stratum ensured that every other interviewee was a female. A sample of 1200 size is sufficient to yield an overall margin of error of +/- 3 percent at a confidence level of 95 percent.
