Women in the U.S. earn less than 80 cents for every dollar a man takes home. Jobs site has analyzed what happens to the gender pay gap after adjusting for attributes like age and education, and comparing men and women in the same occupations. It turns out that the gap shrinks, but does not disappear.
  1. Medicine
    Pay for those in health care varies widely, from orderlies and aides to rock star surgeons. And to some extent, pay gaps exist because of who pursues which medical fields. Among doctors, for example, only 37 percent of anesthesiologists, a highly compensated specialty, are women, but women account for 71 percent of pediatricians, who are among the lowest paid.
  2. Media
    The media world has changed dramatically in the last few years, but its gender pay gap persists. Media was the fifth highest in the Glassdoor survey, at 6.6 percent. One reason is that media include many newer categories, like video-game designers, and pay gaps for those male dominated, tech-heavy jobs may be affecting the media industry's ranking.
  3. Finance
    Finance was once known as a boy's club, and it has an above-average unadjusted pay gap of 6.4 percent — but it fares better than six other industries. There are parts of the business that remain heavily male: Certain trading floors come to mind, for example. But the industry also brings in many young recruits, Chamberlain said.
  4. Entertainment and Hospitality
    The arts, entertainment and hospitality industries are not overly male, but they do have an adjusted gender pay gap of 6.6 percent. Jennifer Lawrence, Hollywood's highest paid female actor, famously earned millions of dollars less than her male counterpart in the year ending in mid-2015, but the difference exists in less rarefied parts of the business as well.
  5. Insurance
    The insurance industry is heavily male, and that is one reason it was tied for the highest pay gap, at 7.2 percent, said Andrew Chamberlain, chief economist at Glassdoor. "Men determine pay and promotions" in the field, for the most part, he said.
  6. Mining
    Metals and mining is a rugged industry, and that may account for the high concentration of men. As with insurance, the predominance of men likely helps to push the pay gap near the top of Glassdoor's list, at 6.8 percent. Industry analyses also show that the mining workforce is aging, and wage gaps tend to widen as workers age.
  7. Transportation
    The transportation and logistics business is heavily male, and it is becoming increasingly technical. Both factors are driving its gender pay gap to the fourth highest in the Glassdoor survey, at 6.7 percent. "Technology is coming in on the logistics side. Database engineers and coders are doing really sophisticated logistics work," Chamberlain said.
