Research from the American Association of University Women shows that even one year out of college, a typical college-educated woman working full time earned $35,296 a year, compared with $42,918 for a typical college-educated man working full time.
Even after controlling for factors known to affect earnings – such as occupation, college major and hours worked – a 7 percent pay gap persists between one-year-out male and female college graduates.
Notice how she left out years of experience and age, two major factors.
Here is an opposing view (BTW - authored by a female).
To compare male and female pay on a level playing field, we found the median pay for all men in a given job, as well as breakdowns of important compensable factors such as years of experience, location, education level, etc. Then, using PayScale's proprietary MarketMatch™ Algorithm, we determined what the female median pay would be using the exact same blend of compensable factors as our control male group.
What we created was an apples-to-apples comparison of what men and women make, all other factors held equal, according to actual market data. For example, the male software developer median, annual salary is $65,700, which is 4 percent more than the median female value of $63,300.
