How Much Do Sources of Happiness Vary Across Countries? A Review of the Empirical Literature

This article presents a review of empirical research exploring cross-national differences in the correlates of subjective well-being (SWB). I start by giving an overview of the concept of SWB across psychological, sociological, and economic literature. Measures of SWB have good cross-cultural validity, yet there is currently little consensus regarding the cultural universality of the definition of happiness. An overview of existing empirical literature points toward robust cross-national differences in mean levels of SWB that are associated with national differences in wealth and other socioeconomic, political, and cultural factors. The degree to which individual-level variables are associated with SWB is also subject to cross-national variations. Many individuals’ characteristics contribute to happiness to the extent that they are beneficial, socially desirable, and aspired to in a particular sociocultural context. These results are discussed in light of two theoretical approaches (institutional and fit hypotheses). Directions for future research are proposed.
