CAIRO—In the last decade, gender rights advocates have, to notable success, made the argument that welcoming women into workforces and economic markets is simply logical policy.

“In the 1970s and 1980s,” wrote Adam Segal in his book Advantage, “underrepresentation was considered primarily a social or moral issue—a question of affirmative action. Today, it is also seen as a competitiveness issue. Only by tapping into emerging demographics” will countries be able to maximize their output.

“Until the last few years,” according to Maddy Dychtwald and Christine Larson in their book Influence: How Women’s Soaring Economic Power Will Transform Our World for the Better, “the massive entry of women into the paid workforce seemed important mostly because it was a victory for social justice. Only recently has another more significant implication of women’s success become clear: The health of the global economy now demands that women realize their full potential as economic participants.”

The argument that including women makes organizations more economically vibrant hasn’t, however, been tapped to make the case for greater gender parity in journalism throughout the world. Gender diversity in newsrooms has been an area of concern in some countries for several decades, but the argument that gender parity strengthens a news outlet’s economic competitiveness is infrequently advanced.

A new report (pdf) of stunning depth released by The International Women’s Media Foundation (IWMF) provides compelling evidence of the underrepresentation of women in journalism throughout the world. It assesses gender disparity at 522 media companies in 59 countries, finding that men occupy two-thirds of all full time positions. Eighty-two percent of full time employees at South Korean news organizations are men, as are just under 70 percent in Argentina and nearly 60 percent in Spain.

The 400-page report, though, mainly uses the moral approach to argue that greater female representation in journalism is important, rather than pointing out that news organizations that hire women are in a better position to compete. Wagging fingers at discrimination is less effective than making the case that equality increases earning power. “Moving people requires a price,” Eduardo Porter wrote in The Price of Everything.

The IWMF report does repeatedly make the case that female economic empowerment is important to overall development, but the economic benefits of employing more female newsmakers—both to news outlets and the news consuming public—aren’t emphasized in the report.

Gender equality within U.S. news organizations has rightly been a focus for decades, and many books and juried journal articles have been devoted to the topic. And since the 1970s, female students have outnumbered males in journalism programs at U.S. universities. Again, though, only recently have American news outlets begun to think more about gender as an economic force. Website sections like the St. Petersburg Times’s GoMomma, the Raleigh News & Observer’s TriangleMom2Mom, and The Arizona Republic’s MomsLikeMe, for example, have been rolled out only in the last few years.

Women are controlling greater portions of global wealth and independently making purchasing decisions. There’s no reason to believe that they won’t also increasingly determine core news organizations in countries throughout the world. Female literacy rates continue to approach male levels in developing markets, empowering millions of women to consume news through means other than TV and radio.

Women don’t represent a niche market, argue Dychtwald and Larson: “Women are the market.”

Only news organizations with the right mix of male and female newsmakers are likely to provide audiences the most complete economic picture, and such a picture will lead female (as well as male) spenders and investors to make better financial decisions.

Journalists guard the public purse, and women look out for other women. And money spared from corruption and waste is generally put to better use by women than men. This is true in both developed countries as well as emerging markets. “Women are more likely to enroll in defined contribution retirement plans and make larger contributions than men,” Dychtwald and Larson wrote. “And they’re more likely to buy and hold investments, rather than churn them.”
