Immigrants who grow old in France do not always benefit from the presence of their children. Some children born in the country of origin have stayed there. Others have come to France and left again, while others, born in France, have emigrated to their parents’ home country or a third country. The migration patterns of the children of migrants are examined in relation to the characteristics of the children and the family’s social and cultural background, highlighting inequalities and the factors behind those inequalities. Daughters are more often left in the country of origin than sons; and children of separated parents more often than children of couples who are together. This analysis uses the results of the survey on retirement of immigrants in France, which includes data about immigrants, their parents and their children (enquête sur le Passage à la Retraite des Immigrés/PRI survey). The paper suggests points for reflection in terms of the possible implications of these “cross-border generations” and on the specifics of intergenerational relations in the context of migration.
