Migration is the movement of people from one place to another, with the intention of settling, permanently or temporarily, in a new location. The movement is often over long distances and from one country to another, but internal migration (within a single country) is also possible; indeed, this is the dominant form of migration globally.

Migrations can be:

• Internal: Moving within a state, country, or continent.
• External: Moving to a different state, country, or continent.
• Voluntary: Choosing to move.
• Forced: Being made to move by someone or something.

Migration is a complex phenomenon with various causes and consequences, affecting both the migrants themselves and the places they leave and arrive in.
