Not all debt is equal: Debt type, burden, and life satisfaction among urban young adults in Seoul

Young adults in rapidly growing cities face mounting financial pressures from escalating housing costs and limited access to stable employment. This study examines how different debt types and perceived debt burden are associated with life satisfaction among young adults in Seoul, South Korea—one of the world's most expensive housing markets. Using four waves (2021–2024) of the Seoul Young Adult Panel Survey, we use individual fixed effects models to estimate within-person changes in life satisfaction associated with debt burden and three debt types: distress debt (living expenses and debt repayment), student loan debt, and housing-related debt. Before adjusting for perceived debt burden, distress and housing debt are negatively associated with life satisfaction, while student loan debt shows no statistically significant association. After adjustment, perceived burden is negatively associated with life satisfaction (b = −0.092, p < .001), the distress debt association weakens and becomes statistically nonsignificant, and housing debt becomes positively associated with life satisfaction. Interaction models further indicate that the associations of distress and housing debt with life satisfaction are burden-contingent: at low burden levels, debt holders report comparable or higher life satisfaction, but at the highest burden level, distress debt holders report 0.318 points lower life satisfaction. These findings highlight how urban financial pressures are differentially associated with young adults' wellbeing depending on debt type and perceived burden, and carry implications for policies addressing financial vulnerability in high-cost metropolitan areas.
