We investigated how intergenerational congruence in family-related attitudes depends on life course stage in young adulthood. Recent data from the Netherlands Kinship Panel Study were used; the present sample included 2,041 dyads of young adults and their parents. Findings are discussed in terms of the elasticity in intergenerational attitude congruence in response to young adults' life course transitions. Our results suggest that intergenerational congruence in attitudes about partnership (e.g., marriage, cohabitation, divorce, women's and men's family roles) decreases after young adults have left the parental home and increases when young adults enter parenthood. Congruence concerning intergenerational obligations was not related to young adults' life course stage.
