I'd been fooling around with Census data a bit over the last week. Here's an interesting chart using Census Table P-36. Full-Time, Year-Round All Workers by Median Income and Sex: 1955 to 2010
Median income for full-time working men first hit 50,000 (in inflation adjusted 2010 dollars) in 1973, and it has been essentially flat ever since (breaking 50k for the second time in 2010.) However, the median income of full-time working women has gone up 35% since 1973. The percentage of full time workers who are women has also increased gradually throughout that time, from 30% in 1973 to 43% in 2010. (In absolute numbers, obviously both the number of male and female full time workers has increased significantly during the same period.)
