France as stopover?

The flight from Paris included husband and wife Moise and Louise Bettan; he is 96 and she is 91. They made aliyah in their wheelchairs.

“We have been dreaming of this moment since 1948,” said Moise.

Both were born in Algeria; now they will live in Netanya, where one of their sons has a home.

Lucid and articulate, Moise said, “I guess we are proof that it is never too late to make aliyah.”

I wonder what percentage of the new French olim are of North African origin, or if this is even knowable, since France doesn't count such things. The counting of people is outside of any research I'm likely to be doing, but if anyone knows the answer to this, I'd be interested.
