Something like 50% of Europeans identify as speaking more than one language. Since 'speaking' is vague, and fluency is hard, I think attaining fluency in multiple languages counts as reasonably 'super' even in Europe.
Exactly. 50% of the population may identify as 'speaking' two or more languages, but I seriously doubt more than 20% of them are fluent in two or more languages. There is an enormous difference between functional and fluent.
