Answer 1

Here's your answer:

Migration-

Human migration is the movement of people from one place to another with the intentions of settling, permanently or temporarily, at a new location. The movement is often over long distances and from one country to another, but internal migration is also possible; indeed, this is the dominant form globally.

Brain Drain-

Brain drain is a slang term indicating substantial emigration or migration of individuals. A brain drain can result from turmoil within a nation, the existence of favorable professional opportunities in other countries, or from a desire to seek a higher standard of living.
