A 2019 Gallup poll found that 34% of Americans believe in astrology. This number has remained relatively stable over the past few decades. However, there is significant variation in belief in astrology by age, with younger people being more likely to believe in astrology than older people. For example, a 2018 Pew Research Center poll found that 40% of 18-29-year-olds believe in astrology, compared to only 25% of those 65 and older.

Belief in astrology is also more common among women than men. For example, the 2019 Gallup poll found that 40% of women believe in astrology, compared to only 27% of men.

Education also plays a role in belief in astrology. For example, the 2018 Pew Research Center poll found that 32% of those with a college degree believe in astrology, compared to 45% of those with only a high school diploma or less.

Overall, belief in astrology is a relatively common phenomenon, especially among younger people, women, and those with less education.
