Economic development, intergenerational mobility, and health in South Korea

Abstract

A growing number of studies reported the association between social mobility and health. However, few studies investigated whether the association varies by age group. Drawing on the economic environment that facilitated social mobility in South Korea, we postulate each age group had a different extent of social mobility, which would vary with the extent of economic growth and affect the association between social mobility and health. We used data from KDI National Happiness Survey 2018 and measured perceived mobility using respondents' perceived social position and their parents' social position. We examined whether social mobility was associated with self-rated health and psychological well-being. The upwardly mobile individuals were more likely than the stable ones to report 'happy'. Such a positive association between upward mobility and happiness was consistently found when the sample was restricted to the ages 30-59 and 40-49. For self-rated health, the downwardly mobile individuals were less likely to report good health. However, no significant difference in self-rated health was found after the youngest and oldest age groups were excluded. We found that perceived social mobility was strongly associated with psychological well-being rather than self-rated health. Moreover, we found a stronger association between upward mobility and happiness among the aged 40-49, who had the largest proportion of upwardly mobile individuals and spent their adolescence during rapid economic growth. The findings underscore the importance of the economic and social context in which individuals perceive their social position and shape their well-being.
