Population migration refers to the movement of people from one place to another, often driven by factors such as economic opportunities, environmental changes, or social conditions. This movement can occur within a country, known as internal migration, or between countries, referred to as international migration. Migration can have significant impacts on both the areas people leave and the places they move to. It can lead to cultural exchange, economic growth, and demographic changes, but may also create challenges such as overcrowding and resource strain in destination areas. Understanding migration patterns is essential for effective policy-making and community planning.
