The reversal of the gender gap in education has reshaped partner formation and challenged traditional family patterns across Europe. As unions where women are more educated than their male partners become increasingly common, understanding their implications for family formation is essential for addressing new social and demographic realities. Research to date provides mixed evidence on how such educationally hypogamous unions influence fertility. This study investigates how the transition to parenthood unfolds across partnership duration in hypogamous versus homogamous unions. Using complete Austrian register data covering all partnerships formed in 2011 and followed through 2021 (N =26 252), we estimate discrete-time hazard models of first birth. By interacting union duration with educational pairing and applying multiprocess models to account for selectivity in both union formation and dissolution, we examine how the meaning of time within partnerships differs across educational configurations. Preliminary results challenge the notion of hypogamy as an initial mismatch that delays childbearing. Instead, hypogamous couples display higher first-birth risks during the early years of their union, with convergence and even reversal at later stages. Accounting for selectivity largely removes this early advantage, suggesting that family-oriented women may self-select into hypogamous unions to realise parenthood earlier. These findings highlight how shifting gender and educational structures interact with partnership dynamics to shape fertility behaviour in contemporary Europe, offering new insights into how populations adapt to changing social realities.
