The John:women ratio

I teach at a relatively small college, with less than 100 faculty members. We monitor the progress of women on the faculty by the John to women ratio--somehow we have way too many faculty members named John. In fact, they recently took a picture of all the Johns (10% of the faculty!)

The good news is: the women are gaining; we're up to twice as many women as Johns.

The bad news is: the reason we're gaining is because the Johns are retiring!
