Gallup measures daily emotions in more than 150 countries and areas by asking residents whether they experienced five positive and five negative emotions a lot the previous day. Negative experiences include anger, stress, sadness, physical pain, and worry. Positive emotions include feeling well-rested, being treated with respect, enjoyment, smiling and laughing a lot, and learning or doing something interesting.
To measure the presence or absence of emotions, Gallup averaged together the percentage of residents in each country who said they experienced each of the 10 positive and negative emotions.
Negative emotions are highest in the Middle East and North Africa, with Iraq, Bahrain, and the Palestinian Territories leading the world in negative daily experiences. Latin America leads the world when it comes to positive emotions, with Panama, Paraguay, and Venezuela at the top of that list.
