This study explores the geography of social inequality and intergenerational mobility in European tertiary education attainment. Analysing data from the European Social Survey (waves 1-10), this study aims to describe the potential role of national as well as regional and sub-regional contexts in shaping individual tertiary education opportunities. Results show substantial cross-country disparities, as well as a sharp divide in inequalities in tertiary education attainment within European countries. In parallel, we observe a general decline in educational inequalities over time, even if this decline is not followed by a convergence in the levels of Inequalities in Educational Opportunities (IEOs) across countries: the differences in educational inequalities between countries remain stable over time, and European countries show great variation in their trends of inequalities in tertiary education attainment over time.
