While a sizeable body of research has focused upon the ‘migrant mortality advantage’ (lower mortality among migrants compared to native-born populations), it has lacked a dedicated age perspective that investigates how mortality varies among migrants across age. This is especially true for older ages. In this chapter, evidence on the mortality of older migrants is summarised utilising the prevailing theoretical framework. The chapter first explores how mortality varies among migrants over age, positioning the mortality patterns of older migrants in the context of younger migrants. Next, it focuses in older migrants to explore heterogeneity in their mortality by sex, age at arrival, and length of stay. Studies that explore the quality of the years lived by older migrants are then summarised, followed by those that evaluate the reliability of mortality estimates among older migrants. The chapter concludes with a synopsis of the condition of the literature on older migrant mortality, followed by suggestions to build on and improve existing evidence.
