【英文】2024年世界幸福指数报告（159页）

Our measurement of subjective well-being  continues to rely on three main well-being  indicators: life evaluations, positive emotions,  and negative emotions (described in the  report as positive and negative affect).  Our happiness rankings are based on life  evaluations, as the more stable measure of  the quality of people’s lives. Life evaluations. The Gallup World Poll, which  remains the principal source of data in this  report, 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. Each respondent  provides a numerical response on this scale,  referred to as the Cantril ladder. 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.  We base our usual happiness rankings on a  three-year average of these life evaluations,  since the larger sample size enables more  precise estimates. Positive emotions. Positive affect is given by  the average of individual yes or no answers  about three emotions: laughter, enjoyment,  and interest (for details see Technical Box 2). Negative emotions. Negative affect is given  by the average of individual yes or no answers  about three emotions: worry, sadness,  and anger.
