Not religious doesn't necessarily mean atheist

But you aren't showing us people who are ditching religion for irreligion, you're showing us people ditching religion a for religion b. They are not changing their religiosity, their delusion, they are simply substituting one focus for another.

Oh, and if you look at countries where people are free to express their religion or lack thereof, the fastest growing group is the irreligious.

I mean...astrology isn't a religion.  It (and other pseudoscience crap) is certainly a delusion, but it's not a religion anymore than being anti-vax or anti-evolution is. And atheists can certainly be astrology believers, the two aren't at all mutually exclusive.
