All French students from the classes of "4ème" have completed a survey about the countries of birth of their parents, grand-parents...

We can notice that only very few of our students were born abroad. But the proportion is more important among parents, and increases even more among grandparents and great-grandparents.

Below, you can see the countries of birth of all the ascendants born abroad.
