Question

Survey Methods Results are based on face-to-face and telephone interviews with approximately 1,000 adults per country, aged 15 and older, conducted in 2011 in 146 countries. Results in Russia, Tunisia, Egypt, the United Arab Emirates, Saudi Arabia, Qatar, Lebanon, Morocco, Jordan, the Palestinian Territories, Bahrain, Yemen, Comoros, Somaliland region, and Iraq are based on data aggregated from multiple surveys. For results based on the total samples, one can say with 95% confidence that the maximum margin of sampling error ranges from ±1.7 percentage points to ±5.7 percentage points. 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.
