What term describes the movement of people from one region to another?

The movement of people from one region to another is best described by the term migration. Migration encompasses a variety of forms, including permanent relocation and temporary movement, and can occur for reasons such as economic opportunity, social factors, environmental conditions, and conflicts.

Urbanization refers specifically to the movement of people from rural areas to urban centers, which is a type of migration but does not cover the broader concept. Emigration is the act of leaving one's country to live in another, focusing on the departure aspect rather than the overall movement. Population growth refers to the increase in the number of individuals in a population, which can be a result of various factors including immigration, but does not directly describe the movement itself. Thus, "migration" is the most accurate and comprehensive term for the movement of people between regions.
