Final answer:
Return migration is the round-trip movement of an individual to their place of origin after spending time elsewhere.
Step-by-step explanation:
A round-trip movement of an individual from one place to another and back again is called return migration. This form of migration typically involves an individual moving back to their original location after spending time in another place. It could be motivated by various factors, including employment, family reunification, or retirement. Return migration is recognized by the National Geographic Society alongside other types of movements such as internal migration, external migration, emigration, immigration, and seasonal migration. Unlike circular or seasonal migration, which may be based on recurrent employment opportunities, return migration implies a more permanent or long-term intention to stay in the place of origin.
