Iraq, Iran and Egypt are the unhappiest countries in the world according to a Gallup report. Lebanon ranks 10th.
Gallup measured negative emotions in 138 countries in 2013 by asking people whether they experienced a lot of anger, stress, sadness, physical pain and worry the previous day. Gallup compiles the “yes” results into a Negative Experience Index score for each country. The higher the score, the more pervasive negative emotions are in a country.
Results are based on telephone and face-to-face interviews with approximately 1,000 adults in each country, aged 15 and older, conducted in 2013 in 138 countries and areas. For results based on the total global sample, the margin of sampling error is less than ±1 percentage point at the 95% confidence level. For results based on country-level samples, the margin of error ranges from a low of ±2.1 to a high of ±5.3. 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.
