Women in their 20s now earn a solid 3.6% more on average than men their age, after narrowly overtaking them for the first time last year. The rise of the female breadwinner, it seems, was no blip, but the beginning perhaps of a social and sexual sea change."
http://www.time.com/time/business/article/0,8599,2015274,00.html"according to a new analysis of 2,000 communities by a market research company, in 147 out of 150 of the biggest cities in the U.S., the median full-time salaries of young women are 8% higher than those of the guys in their peer group. In two cities, Atlanta and Memphis, those women are making about 20% more. This squares with earlier research from Queens College, New York, that had suggested that this was happening in major metropolises. But the new study suggests that the gap is bigger than previously thought, with young women in New York City, Los Angeles and San Diego making 17%, 12% and 15% more than their male peers, respectively. And it also holds true even in reasonably small areas like the Raleigh-Durham region and Charlotte in North Carolina (both 14% more), and Jacksonville, Fla. (6%)."

"New research suggests that fewer women reach those jobs than men because they are less likely to hear about available positions from coworkers as early as their male counterparts.
"Both men and women tend to circulate the good news about job openings or opportunities when they hear about them. But looking at the quality of the job leads in terms of pay and prestige … women get poorer quality leads from other women," said Lisa Torres, a George Washington University sociology professor who studies the hiring and job-search process in corporations. "Men tend to be in the top positions in organizations so, structurally, they're in a position to hear about job openings or opportunities when they arrive, and circulate those to their networks.

While men hold 80 percent of senior management jobs, the gap in income is less severe. According to Huffman's review of 2000 census data, women in senior management earn salaries that trail men's by only 9 percent."
