It's important to celebrate milestones: This is the most women in leadership ever for the Fortune 500, which has been compiled and released since 1955. Last year, women held only 21 of the top slots. That was actually a drop from 2015, which featured 24 women-led companies.
As Fortune noted, the companies ranked "represent two-thirds of the U.S. GDP with $12 trillion in revenues, $890 billion in profits, $19 trillion in market value, and employ 28.2 million people worldwide."
With money comes power, and with power comes influence. And as is evident in the latest definitive ranking, those with the most influence right now are predominantly white and male.
It's not just important to diversify the tippy top of these corporations out of principle — studies show that more equal representation in higher ranks leads to better financial results. And that's good news for everyone.

A previous version of this headline contained a math error. For the Fortune 500 list to include a 50-50 split between men and women, the latter would have to add 43.6 percentage points in representation.
