>Let’s say we define 20%-80% as our threshold, so if a name is used on, let’s say girls, more than 80%, we call the name female-dominant. If it is used on less than 20%, then we call that name “male-dominant” name. Otherwise, we are left with the range from 20% to 80% (60% of all names) which I propose to consider “unisex” names.

Interesting writeup, but this is obviously faulty reasoning.
