please fix this to
A subset of the population who has not yet reached the age of consent
I think society broadly accepts that there are different expectations for children and adults; the line is currently officially drawn somewhere around 18-21 years old.
But in Europe you can drink at 14. Age of consent is also 14.
So, no, there is no official line at 18-21. Especially in the EU.
