It turns out, the difference between men and women's salaries is smaller than we thought — as long as those salaries aren’t very big to begin with. A new study from PayScale.com compared salaries across 90 different jobs, adjusting for any outside factors that might affect the salary (the location of the job, the worker’s education, etc.) except for the worker’s gender. What they found was surprising — to see the results, read on.

In jobs that pay less than $100,000 a year, women make at least 94 percent of what men make — in other words, the gender gap is almost nonexistent (almost). In jobs that pay out over $100k, on the other hand, women make less than 87 percent of what men make. And the higher you go, the bigger the discrepancy gets: female chief executives make 71 percent of what men make, and female hospital administrators make 77 percent of their male counterparts' salaries. So what gives?

Researchers aren’t sure exactly what’s going on, but they have a couple theories. One is that in higher paying jobs, performance is more subjective, and therefore more susceptible to discrimination. Are these findings surprising to you, or just more of the same? What do you think accounts for the widening gender gap in higher paying jobs?
