What is a migration flow?

A migration flow refers to the movement of people from one location to another, often across borders, driven by various factors such as economic opportunities, conflicts, environmental changes, or social factors. It can be characterized by the number of individuals migrating, the direction of the movement, and the duration of their stay in the destination location. Migration flows can be temporary or permanent and can significantly impact both the origin and destination regions economically, socially, and culturally.
