Survey Methods

Results are based on face-to-face interviews with at least 1,000 adults, aged 15 and older, conducted in 2013 in Benin, Botswana, Burkina Faso, Cameroon, Chad, Democratic Republic of the Congo, Gabon, Ghana, Guinea, Ivory Coast, Kenya, Liberia, Madagascar, Malawi, Mali, Mauritania, Niger, Nigeria, Republic of the Congo, Senegal, Sierra Leone, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. For results based on the total sample of national adults, the margin of sampling error ranged from ±3.8 percentage points to ±4.1 percentage points at the 95% confidence level. The margin of error reflects the influence of data weighting. In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
