The bar graph compares the number of French adults whose parents spoke five different regional languages to them during childhood, alongside the number of adults who now speak these regional languages to their own children.
Overall, Occitan was the most widely spoken language during childhood, while Corsican was the least spoken both habitually and occasionally. In contrast, among the adults who now speak a regional language to their children, Alsatian is the most prevalent.

Similarly, Alsatian was the second most commonly spoken language habitually, used by 600,000 people, but only around 240,000 people used it occasionally. Creole and Corsican were the least spoken languages, with approximately 100,000 and 90,000 parents using them habitually, and around 120,000 and 100,000 parents using them occasionally, respectively.
