Population movement refers to the change in the number of people living in a specific area over time. This can happen for various reasons, such as people moving to find better jobs, education, or living conditions. When large groups of people relocate, it can significantly impact both the areas they leave and the places they move to, affecting resources, culture, and community dynamics. There are two main types of population movement: migration and emigration. Migration is when people move within a country, while emigration is when they leave their home country to settle elsewhere. Understanding these movements helps governments and organizations plan for housing, services, and infrastructure to support growing or shrinking populations.
