Question

Different between long term migration and short term migration

Answer 1

Unlike for Long-Term International Migration (LTIM), there are no estimates of short-term international net migration. Short-term migrants do not stay for more than 12 months; therefore, they do not become “usually resident”.

“A person who moves to a country other than that of his or her usual residence for a period of at least a year (12 months), so that the country of destination effectively becomes his or her new country of usual residence

A person who moves to a country other than that of their usual residence for a period of at least three months but less than a year (12 months) except in cases where the movement to that country is for purposes of recreation, holiday, visits to friends or relatives, business, medical treatment or religious pilgrimage.
