Today a graphic in the Times plots weekly median wages for men and women by occupation. It reveals broad but also heterogeneous inequality in earnings.
Professors and postsecondary teachers, my group, is at male weekly earnings = $1,250 and female weekly earnings = a little less than $1,000. There is vast heterogeneity within that occupational group, which includes tenured, tenure-track, and adjunct professors, stepping from highest rank to lowest. Rank and earnings are correlated, as are rank and sex and probably rank and job flexibility.
A graphic like this is interesting, but it is hard to know the takeaway message other than the fact that wage inequality is broad-based across occupations or industries.
