While most research shows women make 83 cents to a man’s dollar, a new study confirms that gap is even wider among women with a Bachelor’s degree. 

According to a recent analysis by the U.S. Census Bureau, women with a bachelor’s degree earn 74 cents for every dollar their male counterparts make. Surprisingly, the pay gap is actually less for women without a bachelor’s degree — 78 cents for every dollar men earn, Marketwatch reported.

The findings further show that even though women account for more than half of those pursuing higher education, they get less out of it — at least when it comes to pay. Other research showsthat women with a bachelor’s degree earn roughly the same on average as men with an associate’s degree.

The Census analysis suggests reasons why. Among them is the theory of “occupational segregation,” or the idea that female-dominated jobs tend to pay less, is perhaps one of the biggest factors. In other words, educated women typically choose to major in professions that are less lucrative.
