Women’s median earnings are lower than men’s in nearly all occupations, whether they work in occupations predominantly done by women, occupations predominantly done by men, or occupations with a more even mix of men and women. During 2011, median weekly earnings for female full-time workers were $684, compared with $832 per week for men, a gender wage ratio of 82.2 percent. Added to the gender wage gap within occupations is the gender wage gap between occupations. Male-dominated occupations tend to pay more than female-dominated occupations at similar skill levels, particularly at higher levels of educational attainment. Tackling occupational segregation is an important part of tackling the gender wage gap.
