Women have come a long way in this industry over the past decade or two. GlobeSt.com recently reported on a study by Ferguson Partners that found that REITs with at least one woman on their boards have seen significantly higher shareholder returns than those with no women—2.6% higher over a three-year period and 3.6% over five years.

That’s great news for women in this business. It also bodes well—relatively speaking—that 56% of the REITs have a female member of the board, whereas just 11% of Fortune 500 companies do. There were some advances broadly, though; in this year’s Fortune 500 ranking, 18 firms had female CEOs, up from 12 in 2011 and a mere seven a decade ago.

Still, that’s just 3.6% of the entire list. In the finance and insurance industries in particular, women make up 57.6% of the labor force, but only 18.4% of executive office positions, and only 3.7% of CEOs are female.
