One in four Americans say they believe in astrology | YouGov

YouGov’s latest poll finds that a little more than one-quarter of Americans (27%) – including 37% of adults under 30 – say that they believe in astrology, or that the position of the stars and planets influences people’s lives. About half of Americans (51%) say they don't believe in astrology and 22% are unsure.

@mattsheffield Pity they didn't poll by sexual orientation. I joke how astrology is the official religion of the LGBT community.
@krankenbrueder That's an interesting thing to hear. Do you think people are believing in it or just talking about it for fun?
@mattsheffield Both. It's a low pressure folk spirituality in a community that tends to have less affinity for traditional religion.
@krankenbrueder So I guess another way of saying "spiritual but not religious?"
