Emigration 移民出境
(重定向自Emigrant)
Emigration is the act of leaving one's resident country with the intent to settle elsewhere. Conversely, immigration describes the movement of persons into one country from another. Both are acts of migration across national boundaries.
Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Seeking refugee status in a foreign country from oppressive conditions may lead to permanent emigration.
