Over the past years the population of older migrants has risen continuously (Ciobanu et al., 2017). In the early 2000s, Warnes and colleagues (2004) raised awareness of the diversity in the older migrant population, and since then more scholars have stressed the importance of acknowledging the heterogeneity within this group (Ciobanu, 2019; Ciobanu et al., 2017, 2020; King et al., 2017; Torres, 2006). The increase in both the ageing and the migrant populations worldwide is creating a new social reality. To engage with it, there is a need for concepts and theoretical reflection and development, the lack of which has already been criticised (Phillipson, 2015; Torres, 2015). Therefore, this chapter enquires how the concepts of super-diversity and intersectionality can be relevant to problematise and advance the theoretical developments in the study of emerging populations and research themes at the intersection of ageing and migration.
