Population mobility refers to the movement of people from one location to another, which can occur within a country or across international borders. This movement can be driven by various factors, including economic opportunities, social conditions, environmental changes, and political situations. There are different types of population mobility, such as internal migration, where individuals move within their own country, and international migration, where people relocate to a different country. Understanding population mobility is essential for addressing issues like urbanization, labor markets, and the provision of services in both sending and receiving areas.
