Despite the shrinking gender wage gap and more women in high executive positions, many women still want their partner to be the breadwinner — or at least make the same amount as they do.

More than 1 in 5 women — 22% — say they wouldn’t date someone who makes less money than them, according to a new survey of 3,000 singles across the U.S. from dating company Plenty of Fish. That’s compared with just 4% of men and 11% of single people overall who said they wouldn’t date someone who makes less money than they do. The same study found 85% of singles tell the truth about how much they make.

Money issues are persistently important to people in relationships: More than half of Americans wouldn’t marry someone with significant debt, another recent study from legal industry site Avvo found, and 58% in the same study said they would feel uncomfortable being the main breadwinner in a relationship. The breakdown varied by gender in that study as well: 69% of women said they’d be uncomfortable footing all the bills compared with 46% of men. “People don’t want to be in a relationship that will economically disadvantage them,” said Moira Weigel, author of “Labor of Love: The Invention of Dating.”

And it doesn’t end there. A separate study of roughly 12 million consumers by researchers at the Federal Reserve Board, the Brookings Institution and UCLA found couples’ credit scores can predict how likely it is that their relationships will last. The higher your credit score, the less likely you are to separate from a partner — and for every 105-point spike in that credit score there is a 32% drop in the likelihood of them separating. However, money can’t buy love, as the old saying goes, and people who look only at financial profiles could be limiting their dating pool, said April Masini, a New York City-based relationship and etiquette expert and author.

Women already make less money than men for the same jobs — 83 cents on the dollar — and they want a partner who they don’t have to support, Masini. “Men complain that they lose wealth to gold diggers,” she says. “Women want to protect their wealth.” But women shouldn’t be too quick to judge, Masini says. “Someone who earns less may make a terrific partner,” she says. “If a woman with money is willing to give that a whirl.”

She may have a point. Men with higher incomes showed stronger preferences for women with slender bodies, while women with higher incomes preferred men who had a steady income or made similar money, according to a 2016 survey of 28,000 heterosexual men and women aged between 18 and 75. The study was conducted by researchers at Chapman University in Orange, Calif., and was published in the the peer-reviewed academic journal “Personality and Individual Differences.”

The importance of income reflects broader social trends, say Shannon Smith, communications manager at Plenty of Fish. “We are in the midst of a women’s empowerment movement, and a broader conversation about the gender pay gap, so this could be a powerful representation of how women see their worth.” It’s a subject everyone should breach, she says, “before it becomes more of a taxing conversation than it should be.”
