Data on tolerance is drawn from the Gallup World Poll. The Gallup World Poll is conducted in over 140 countries around the world based on a common questionnaire, translated into the predominant languages of each country. With few exceptions, all samples are
probability based and nationally representative of the resident population aged 15 years and over in the entire country, including rural areas. While this ensures a high degree of comparability across countries, results may be affected by sampling and non‐sampling
error. Sample sizes vary between around 1 000 and 4 000, depending on the country. The tolerance index is the ratio of the people who respond yes to the question of whether the city or area where they live a good place or not a good place to live for ethnic minorities,
migrants, or gay or lesbian people to all people contacted.
