Immigration and emigration are two concepts related to population movement, but they have opposite meanings:
Immigration refers to the act of entering and settling in a foreign country, usually with the intention of residing there permanently or for an extended period of time. In other words, it is the movement of people into a country.
Emigration, on the other hand, refers to the act of leaving one’s own country to settle in another country, usually with the intention of residing there permanently or for an extended period of time. In other words, it is the movement of people out of a country.
In summary, immigration refers to people moving into a country, while emigration refers to people moving out of a country.
