 An illustrative study of the correlates of happiness from a global perspective is the Gallup World Poll study noted earlier (Diener, Ng et al. 2010; see also Jebb et al. 2020). In that study, the life satisfaction measure was more strongly related to material prosperity, as noted above: household income, along with possession of luxury conveniences and satisfaction with standard of living. The affect measures, by contrast, correlated most strongly with what the authors call “psychosocial prosperity”: whether people reported being treated with respect in the last day, having family and friends to count on, learning something new, doing what they do best, and choosing how their time was spent.
