This study delves into the conceptual core, analyzes the theoretical background, and conducts an empirical investigation of intergenerational social mobility trends based on distinct and deeply entrenched types of welfare states in Europe. The welfare state is recognized as a key component in social stratification and mobility, and for this reason, its interactive role in mitigating the significance of social inheritance for individuals' future achievements is examined. Utilizing intergenerational microdata through categorical analysis methods, this study highlights the dynamics of intergenerational social mobility within country clusters based on welfare state types in Europe. The findings of the study enrich the relevant academic dialogue and can contribute to the design of policy measures to promote intergenerational social mobility through strengthening social protection mechanisms in Europe.
