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 2012, median weekly earnings for female full-time workers were $691, compared with $854 per week for men, a gender wage ratio of 80.9 percent (Table 1; a gender wage gap of 19.1 percent).1 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 in jobs that require higher educational levels.2 Tackling occupational segregation is an important part of eliminating the gender wage gap.
