What do we call the movement of people from one place to another?

The term that best describes the movement of people from one place to another is migration. Migration refers specifically to the relocation of individuals or groups from one geographical area to another, often with the intent of settling either temporarily or permanently in the new location. This can occur for various reasons, including economic opportunities, social factors, environmental changes, or political situations.

In contrast, transition generally refers to a process of change in a state or condition and is not specifically tied to the movement of people. Resettlement implies a more structured process where individuals or groups are relocated, often by an authority or organization, typically due to conditions such as conflict or natural disaster. Commute, on the other hand, refers specifically to the regular travel of individuals between their place of residence and their place of work or education, which typically involves shorter distances and is not synonymous with migration.
