Currently, 125,000 Mongolians are living and working abroad, of whom 25,000 are in South Korea. Each year several thousand people travel to that country, in order to work - mostly in the industrial sector. A sociological study of the broader family problems shows the psychological difficulties often faced by their children, who are left in Mongolia with grandparents. The study also shows that many couples who have been separated over the course of several years, as a result of one of the pair working abroad, end up getting divorced. As the number of Mongolians going abroad to work seems to be on the incease, the family issues raised in the study are likely to become more serious.
