Even when controlling for age, education, experience, occupation, industry, location, company, and job title, the adjusted gender pay gap in the tech field was 5.9% in the US. That means that US women working in tech earn, on average, $0.94 cents for every $1.00 men in the field earn.
The national adjusted pay gap is 5.4%, the report stated.
"Our detailed analysis reveals that even when factors such as age, job title and location are controlled for there is still an unexplainable pay gap between women and men—and that isn't acceptable," said Glassdoor CEO and co-founder Robert Hohman.
The largest wage gap was for computer programmers, with a 28.3% difference between males and females in the position. It was followed by game artists (15.8%), information security specialists (14.7%), software architects (10.6%), and SEO strategists (10.2%).
Rounding out the bottom of the list with smaller wage gaps were product managers (4.3% gap), mobile developers (2.9%), and hardware engineers (1.9%).
The data is based on 504,438 salary reports shared on Glassdoor by US-based, full-time workers as of November 2015.
Part of the gender pay gap nationally across industries is due to occupational sorting, with women and men working in different industries and jobs, according to Shelley Correll, a professor of sociology at Stanford University, in a press release. Stereotypes about women's technical and leadership abilities determine not only who enters the tech field, but who advances within tech companies, Correll said.
"We find that, even once [they've entered] the technology industry, women can find themselves steered out of technical roles and into careers such as marketing, human resources and project management, which often pay less and may not have the same potential for advancement," Correll said. Further, unconscious bias may cause managers to question the technical abilities of women, slowing their career pathways to higher-paying jobs. As a result, women are less likely to stay in tracks like engineering, Correll said.
One way to solve the problem is pay transparency, Hohman said. "Pay transparency is a critical step to illuminating pay inequities so that employers and employees can take steps to close existing pay gaps," he said.
In conjunction with the Glassdoor report, the Clayman Institute for Gender Research and Stanford's School of Engineering will host a roundtable discussion on pay equality, broadcast live here on November 15 at 11:30 a.m. ET.
