This is really interesting.
Created by lemonde.fr it's an interactive graphic that shows the most popular French boys and girls baby names in each région since 1946. Click here for the link.
This is really accurate because when I think about students that I've taught, teachers I've had, people I've met, friends I've made and their approximate ages, it matches up well. I have, however, met a lot of Oliviers which doesn't appear on the list/map.
Personally, I'm not a fan of common names though and there are some on that list I really don't like. I don't think Manon sounds like a very nice girl's name. I had a student called Manon.
