The poll only counts people who talk about it "often or extremely often".

It actually seems crazy to me that the number is so high for younger age groups:

> And young adults are more likely to say they often talk about their mental health with close friends: 37% say this, compared with 29% of those 30 to 49 and 14% of those 50 and older.

That's a lot of mental health talk. I suspect you won't see this amount of mental health talk in places with good average mental health.
