According to the U.S. Bureau of Labor Statistics, fully employed women earn $0.81 for every dollar men make. Some of this discrepancy is due to women working in male dominated occupations, but when men work alongside women in female-dominated occupations, they still earn more.

Nursing is this week’s example. According to a new study in the Journal of the American Medical Association, male nurses out earn female nurses in every work setting, every clinical setting, and every job position except one.

On average, male nurses make $5,100 more a year than female ones. In the specialty with the biggest discrepancy, nurse anesthetists, they out earned women by $17,290. More at NPR and the New York Times.
