Third Culture Kids

A Third Culture Kid (TCK) is a person who has spent a significant part of their developmental years outside of their parents' culture(s). TCKs often have a hybrid cultural identity that incorporates elements of their parents' culture(s), the culture(s) of the country they lived in, and the unique culture that emerges from their international experiences.

TCKs may have grown up in multiple countries due to their parents' work, or they may have been raised in a foreign country due to their own choice or circumstance, and may face unique challenges in navigating their cultural identity, including feeling like they don't fully belong to any particular culture or struggling to form deep, long-lasting relationships due to their frequent moves.

Overall, being a Third Culture Kid can offer unique opportunities and perspectives, but it can also come with its own set of challenges.

Cross-cultural children include Third Culture Kids (TCKs) and the children and adolescents whose families have immigrated to a new society.  TCK is closely related to who is referred to as "expats" vs those who are referred to as "immigrants".
