A new snapshot of trends at mid-cap companies show women are far less likely than their male counterparts to reach top leadership positions at those firms.
On the bright side, however they are starting to close a pay gap with men and - in a cluster of industries - even out-earn them.
Researchers at Georgetown University's McDonough School of Business surveyed about 2,000 executives at companies with stock market capitalization of $1 billion to $7 billion, so-called mid-cap firms.
They found that women made up 4.5 percent of the top leadership in 2010. That is far less than at larger firms, where other data show women make up about 14 percent of executive positions.
