What is the definition of migration according to the text?

The correct choice defines migration as the movement of people from one place to another, capturing the essence of the concept by focusing on the act of movement itself. This definition encompasses both permanent and temporary relocations, as well as movements across different distances, including international and internal migration. Migration can include various forms, such as voluntary, involuntary, temporary, or permanent movements, thereby illustrating the complexity and breadth of human mobility.

The other options are more restrictive or specific. One suggests that migration must be a permanent move, which excludes temporary migration patterns that are also significant. Another focuses on adjustments in residence, which may not fully represent the broader range of migration experiences. Lastly, the option that limits movement only within national borders overlooks international migration, which is also a critical aspect of the phenomenon. Therefore, the chosen definition most accurately reflects the multifaceted nature of migration.
