Third culture kid (TCK) or third culture individual (TCI) are terms used to refer to children raised in a culture other than their parents' (or the culture of the country given on the child's passport, where they are legally considered native) for a significant part of their early development years. They are exposed to a greater variety of cultural influences. For adults who have had this experience as children, another term used is adult third culture kid (ATCK).
TCKs move between cultures before they have had the opportunity to fully develop their personal and cultural identity. The first culture of such individuals refers to the culture of the country from which the parents originated, the second culture refers to the culture in which the family currently resides, and the third culture refers to the amalgamation of these two cultures.
Currently, there are as many bilingual children in the world as there are monolingual children. TCKs are often exposed to a second (or third, fourth, etc.) language while living in their host culture, being physically exposed to the environment where the native language is used in practical aspects of life. "TCKs learn some languages in schools abroad and some in their homes or in the marketplaces of a foreign land. ... Some pick up languages from the nannies in the home or from playmates in the neighborhood" (Bell-Villada et al. 23). This language immersion is why TCKs are often bilingual, and sometimes even multilingual.
Some well-known TCKs include the 44th President of the United States, Barack Obama, and Abby Huntsman, daughter of former U.S. Ambassador to China and former Governor of Utah Jon Huntsman Jr., who lived in Beijing and various other Asian cities due to her father's career path.
The term "third culture kid" was first coined by researchers John and Ruth Useem in the 1950s, who used it to describe the children of American citizens working and living abroad. Ruth Useem first used the term after her second year-long visit to India with her fellow sociologist/anthropologist husband and three children.
