A Third Culture Kid (TCK) is a person who has spent a significant part of his or her developmental years outside the parent’s culture. The TCK builds relationships to all of the cultures, while not having full ownership in any. Although elements from each culture are assimilated into the TCK’s life experience, the sense of belonging is in relationship to others of similar background.

If you hate being asked “Where are you from?,” chances are, you’re a Third Culture Kid… TCKs are, quite literally, citizens of the world. They are hard to define and are made of an infinite amount of experiences.
