Parental age at childbirth and children’s educational outcomes: evidence from upper-secondary schools in Italy

In the last decades, Western societies have been involved in huge demographic changes, amongst which one of the most important has been the increasing postponement of the transition to parenthood. This paper aims at analysing the consequences of later motherhood and fatherhood on children’s participation in upper-secondary schools in Italy, considering both the vertical and horizontal dimensions of education. It also aims at highlighting the role of father-mother age difference and heterogeneity in the effects by parental SES and birth order. Using Italian labour force survey data (2005-2014), results show that late parenthood is positively associated with educational attainment, whereas teenage and early parenthood negatively affect children’s educational outcomes, net of detailed information on parental SES. Age at parenthood affects the educational achievement mostly for children of low- and middle-educated parents, who are more penalized by early childbearing and more favoured by late parenthood than the offspring of the tertiary educated. Moreover, only children are less affected by age at parenthood, especially in comparison with later-born children. Finally, children’s educational outcomes are worse when the mother is older than the father, independently from the educational outcome considered, whereas they are better in case of parental age homogamy or when the father is slightly older than the mother.
