Which of the following scenarios best exemplifies labour migration?

Labour migration specifically refers to the movement of individuals from one location to another primarily for the purpose of employment. In the scenario of seasonal agricultural workers moving between states, these workers relocate temporarily to find better job opportunities related to agriculture, which is a clear representation of labour migration. They follow job availability and seasonal demands, directly linking their movement to employment opportunities.

The other scenarios represent different types of migration. For example, a family relocating to a new country involves a broader context of permanent relocation, which can encompass various reasons beyond work. Retired individuals moving to a new community is primarily demographic in nature and focuses on lifestyle changes rather than labour-related reasons. Similarly, students studying abroad typically migrate for educational purposes rather than for employment, which distinguishes them from labour migration. Thus, the scenario of seasonal agricultural workers best represents the concept of labour migration.
