Transitions to adulthood not only represent a key period for individual development but also contribute to processes of social stratification. Growing evidence has pointed to increased complexity, postponement and individualization in transition dynamics. Previous research has focused on trends in school-to-work transitions and family formation; however, the central role of housing represents an interrelated process that is less understood. As pathways to adulthood have diversified, many young people experience partial independence in one sphere while continued dependence in others. Semi-dependent housing, either through parental coresidence or shared living, can be an important coping mechanism. Using the EU-SILC dataset, the research investigates the role that semi-dependent living plays within emerging adulthood across varied European contexts. The data suggests that the extent and type of semi-dependent housing varies substantially across EU15 countries. The findings indicate that levels of housing independence can be partly explained by welfare regime context while the propensity for shared living appears correlated with affordability in the rental market.Although socio-cultural and economic trends play an important and interrelated role, the study argues that housing dynamics of young adulthood and the role of semi-dependent living is fundamentally shaped by the context of the housing system and welfare regime.
