The Afrobarometer is an independent, non-partisan research instrument that measures the social, political and economic atmosphere in Africa. Between 28 September and 16 October 2008, the Afrobarometer surveyed a nationally representative, random, stratified probability sample of 1200 adult Batswana citizens. Face-to-face interviews were conducted by the Afrobarometer team based at the University of Botswana in two languages: English and Setswana.
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 2006 population projections provided by the Central Statistics Office (CSO) based on the 2001 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.
