An intriguing observation. How are you defining 'atheist,' then?
One who does not believe in the existence of any god.
My observation is that almost no one I have ever met, or read, or heard about, believes in the existence of any god.
Many people say things or pantomime their way through rituals in such a way as to appear to be theist as a survival instinct... but none of them have ever demonstrated a belief in existence of a god.
I will stand corrected if provided sufficient evidence of someone's belief, though.
