The term for the movement of people from one place to another is migration. Migration can occur on various scales, including local, regional, national, or international. People migrate for numerous reasons, often driven by economic opportunities, political instability, social factors, or environmental changes. This movement can be voluntary, such as seeking better employment, or involuntary, as in the case of refugees fleeing conflict or disaster. Migration significantly impacts demographics, cultural exchange, and social dynamics in both sending and receiving regions, shaping societies and economies around the world throughout history and continuing today.
