If your name is John, congratulations. If you’ve got a woman’s name — literally any woman’s name — well, here’s the deal.

The New York Times’ data journalism venture The Upshot reported Monday there are more CEO’s named “John” at S&P 1500 companies than there are women CEOs.

If you toss the names Robert, William and James in the mix, you end up with four CEOs with those names for every female CEO. The Upshot has dubbed that measurement the “Glass Ceiling Index,” and they spun it out to several other institutions and fields:

It’s not a perfect measure of equality — the Times notes common names won’t change at the same rate as gender representation — but it’s a stark snapshot of women’s standing in the boardroom.
