Men on average earn 24.1 percent higher base pay than women, and many tech jobs top the list for the largest gender pay gaps, according to a new study from employment site Glassdoor.

The study [PDF], which is based on more than 505,000 salaries shared anonymously by full-time U.S. employees on Glassdoor, found that women earn about 76 cents for each dollar a man earns. And the occupation with the highest gender pay gap? Computer programming, a field where 81 percent of workers are men, with a gap of 28.3 percent.

"This amounts to women [computer programmers] earning on average 72 cents per dollar earned by men, after controlling for all differences between jobs, companies, and workers—a gap that is roughly five times larger than the U.S. average 'adjusted' gender pay gap of 5.4 percent," the report notes.

Those in the field of computer aided design (CAD) also face a larger-than-average gender pay gap of 21.5 percent.

On a somewhat more positive note, the report also found that while many tech jobs display large gender pay gaps, the overall information technology industry is "close to the U.S. average and falls in the middle of the pack among industries" with a 5.9 percent adjusted gap. Healthcare, insurance, mining, transportation, media, arts, finance, retail, and construction industries all face higher gaps than IT.

The main takeaway of the study, however: "The gender pay gap is real, both in the U.S. and around the world," Glassdoor wrote. "Men earn more than women on average in every country we examined, both before and after adding statistical controls for personal characteristics, job title, company, industry and other factors designed to make an apples-to-apples comparison between workers."
