The gap in average wages between men and women workers has been gradually narrowing, but very gradually. Some say that this gap stems largely from the difference in type and rank of job and from the fact that the women's length of working years is shorter than that of men. The Employment Policy Foundation's Nordquist says one reason women's pay is lower than men's is that

The study sample included data from 2,178 managers from 512 different companies across a wide variety of industries and functional areas. The manager’s sex, age, race, organizational level, experience, education, performance, and functional area were taken into account prior to examining the effect of the gender and age composition of managers’ referent groups.

women are more apt to be liberal arts majors who go into lower-paying jobs, while men are inclined to choose engineering and computer-science courses and pursue higher-paying careers. But others argue that these aren't examples of poor career choices by women, but of careers dominated by men which would be a subtle form of discrimination that undervalues women and some of the work they do.

Demonstrating that there is still not equal pay for equal work, in 1997, female public relations and marketing managers earned 31% less than male managers, female elementary school teachers earned 9% less than male elementary school teachers, female retail sales workers made 32% less than male counterparts, and female economists made 27% less than male economists. Even among recent college graduates, women earn 15.7% less than men. While women constituted 46% of the work force in 1995, over 63% of all workers earning the minimum wage or below were women.

The Lorenz curve can be used to show the differences in men’s and women’s wages. It was developed by Max O. Lorenz as a graphical representation of income inequality. It can also be used to measure inequality of assets or other distributions. The Lorenz curve is a graph that shows, for the bottom x% of households, the percentage y% of the total income which they have. The percentage of households is plotted on the x axis, the percentage of income on the y axis. (wikipedia)
