Introduction: The ‘second-generation’ (i.e. the children of migrants) represent one of the fastest growing subpopulations of the child and young adult populations in Europe today. The research so far appears to indicate that their mortality risk is elevated relative to people with non-migrant backgrounds.

Sources of data: Peer-reviewed publications.

Areas of agreement: Second-generation status is a clear marker of elevated mortality risk in Europe in early life (including stillbirth, perinatal, neonatal and infant mortality) and adulthood, particularly if the parent(s) were born outside of Europe. Socioeconomic inequality plays an important, albeit rarely defining, role in these elevated risks.

Areas of controversy: It remains unclear what causes-of-death are driving these elevated mortality risks. The exact influence of (non-socioeconomic) explanatory factors (e.g. health care, racism & discrimination, and factors related to integration) on the elevated mortality risks of the second-generation also remains unclear.

Growing points: The second-generation will continue to grow and diversify in Europe; we must intervene to address these inequalities now.

Areas timely for developing research: Place more emphasis on the complexity of migration background, specific causes-of-death, and understanding the roles of explanatory factors beyond socioeconomic background.
