This systematic review of empirical literature investigated the extent to which growing up as a TCK impacts identity and belonging. An initial yield of 509 articles was found across seven databases, with six final research articles used for analysis. Content analysis revealed three identity themes: identity negotiation, cultural multiplicity, and a pervasive otherness from the passport country. Three belonging themes were identified: belonging everywhere and nowhere, a home with other cross-cultural individuals, and a home in identifying as a TCK.
