Incidentally for native speakers Chinese is the most widely used 1st language followed by Spanish and then English. French does not make the top 10
However for most widely spoken language English is 1st above Chinese with Hindi third. French is below Spanish with less than 1/4 of the english speakers.
Welsh does't get listed but it is about 500,000 speakers!
I work across multiple countries and find that English is the lingua franca even in France.
