According to the report the measurement of subjective well-being relies on three indicators:
life evaluations, positive emotions, and negative emotions.
Life evaluations, according to the report, are based on theGallup World Poll, which asks respondents to evaluate their current life as a whole using the image of a ladder, with the best possible life for them as a 10 and worst possible as a 0. Typically, around 1 000 responses are gathered annually for each country. Weights are used to construct population-representative national averages for each year in each country. The happiness rankings are based on a three-year average of these life evaluations.
Positive emotions are derived from the average of individual yes or no answers about three emotions: laughter, enjoyment, and interest; while negative emotions are from average of individual yes or no answers about three emotions: worry, sadness, and anger.
