Third culture kids or TCK is a broad term to describe the effects of raising a child in multiple cultures in addition to that of their caregivers. This often results in the child combining elements of multiple cultures into a unique “third culture” of their own. This means that they receive sort of a mixed acculturation, where the cues and symbols of various cultures combine to form a single whole.
Third culture kids as adults tend to do well moving between various countries and cultures but often have a difficult time adapting to their home culture. Though, after a period of adjustment, they are generally successful.
