The correct answer is: Out-migration.
Out-migration is the movement of people away from a particular place. It is the opposite of in-migration, which is the movement of people into a particular place. Emigration is the act of leaving one’s country to settle in another country. Immigration is the act of coming into a country to settle there.
In the case of people leaving Goa to settle in other states or countries, this is an example of out-migration. This is because the people are leaving Goa and settling in other places. This can be due to a number of reasons, such as economic opportunities, better education, or a desire to live in a different culture.
Emigration is not the correct answer because the people are not leaving Goa to settle in another country. Immigration is also not the correct answer because the people are not coming into Goa to settle there.
