Women may do more of the nation’s nursing work, but men are still getting paid more to do the same jobs.

That’s according to the annual Nurse.com Salary Research Report, which polled about 4,500 RNs nationally to reveal male nurses averaged $79,700 in salary, while females brought home about $73,100.

According to the study, men make up only about 12% of the nursing workforce, but they earn more even when researchers factored in age, experience and education.

“Based on this survey, it seems clear men are being paid significantly more than women in the profession, doing comparable work,” said Brent MacWilliams, Ph.D., RN, president of the American Association for Men in Nursing.

“I would call on employers to assess their current workforce for gender gaps and raise salaries to create parity.”

Among female survey respondents, about 60% held professional certification for their roles, while about 65% of men did. The gender pay gap among certified registered nurses was smaller, at about $1,250.

Another possible reason for the disparity: Just 34% of women said they regularly negotiated their pay.
