NEW YORK — A lot of American adults — about 3 in 10 — make use of astrology, tarot cards or fortunetellers at least once a year. But only a small fraction of them rely on what they learn from these practices to make major decisions.

That’s according to a nationwide survey released Wednesday by the Pew Research Center, encompassing 9,593 U.S. adults who were interviewed last October.

Overall, according to Pew, about 2 in 10 U.S. adults say they engage in at least one of these activities mostly “just for fun,” while about 1 in 10 say they engage mostly because they “believe the practices give them helpful insights.” Only about 1% say they rely “a lot” on what they learn from these practices when making major life decisions.

Yet it’s a big business. The psychic services industry — which encompasses various specialties such as astrology, palm-reading, psychic readings and fortunetelling — generated an estimated $2.3 billion in revenue in 2024 and employed 105,000 people, according to market research firm IBIS World.

“Traditional skepticism about consulting psychics has waned, with more consumers embracing these services, especially in times of uncertainty,” wrote IBIS World analyst Michal Dalal.

There were some major demographic differences in responses to the Pew survey, notably finding that younger adults — and especially younger women — are more likely than other major age groups to consult astrology or horoscopes. According to Pew, about 4 in 10 women ages 18 to 49 say they believe in astrology. That compares with about 3 in 10 women 50 and older and about 2 in 10 men under age 50.

According to the survey, about half of LGBTQ+ adults consult astrology or a horoscope at least yearly — roughly twice the share among U.S. adults overall.

The survey found that adults ages 65 or older, those with high incomes and college degrees, and those who identify as politically conservative are less likely than other adults to believe in astrology and engage with tarot cards and fortunetellers.

Among other questions, Pew asked respondents if they were religiously affiliated, and about 7 in 10 said yes. Of that group, about 3 in 10 said they believe in astrology — very similar to the percentage of astrology believers among the religiously unaffiliated respondents who identified as atheist, agnostic or “nothing in particular.”

About one-third of Black Protestants, Hispanic Catholics and adults who say their religion is “nothing in particular” said they believe in astrology, according to Pew. Atheists, agnostics, white evangelical Protestants and Jewish Americans, meanwhile, were less likely than the general public to say they believe in astrology.

Among Hispanic Catholics, about 1 in 10 said they rely on insights from these practices at least “a little” when making major life decisions, which was more than most of the other religious groups in the survey.

On the specific question of astrology, the survey found 27% of U.S. adults believed in it — similar to the 29% who answered affirmatively in a 2017 Pew survey.

IBIS World said the psychic industry’s total revenue is up by more than 4% a year since the start of the pandemic five years ago, “when business closures, sickness and loss of loved ones prompted a surge in demand for spiritual guidance services.”
