An astronaut family is a family unit where the members reside in different countries across the world—in contrast to a "nuclear family".[1][2] The astronaut family represents the growing transnationalism of peoples' identities that accompanies the growing globalization.
The term was coined by Aihwa Ong in her publication Flexible Citizenship: The cultural logics of transnationality in 1999.[3] The term is especially used to describe Chinese families, who have spread across the globe.[4]
