I'm being pedantic, yes, but it's 13 to 19 inclusive. Not 10 to 19.

This is a language issue then, here in NL when you are '10' you are officially a 'tiener', even if you are a young one.

It used to be 13 to 20 here, but that was a long time ago.

Apologies, I just took the dutch word 'tiener' to mean 'teenager' in English. My bad.

So that raises the median age by a year and a half.
