I understand i may be a bit late on this, but here is some kind of data (not sure about its reliability): http://www.nytimes.com/2011/12/14/us/14iht-letter14.html?_r=1 http://www.nytimes.com/2011/12/14/us/14iht-letter14.html?_r=... ... And a study shows that in most U.S. cities, single, childless women under 30 are making an average of 8 percent more money than their male counterparts, with Atlanta and Miami in the lead at 20 percent. ... Still, society-wide, gender gap still exists. So it must be due to the rural workers (more manual work the kind of men are naturally a better fit for -> not a discrimination), and mainly, parenting. So it's a question if there is a discrimination here at all.
