The term for the movement of people from one country to another is "migration." Migration can occur for various reasons, including economic opportunities, safety from conflict or persecution, environmental changes, or family reunification. It can be voluntary, as in the case of individuals seeking better livelihoods, or involuntary, as seen in refugees fleeing war or disaster. Migration has significant impacts on both the host and origin countries, influencing demographics, economies, and cultures. It plays a vital role in shaping societies and can lead to the exchange of ideas, skills, and traditions across different cultures.
