Why is she called Supergirl and not Superwoman?

It's widely thought that Kara is referred to as Supergirl because of her younger age. While this definitely makes sense, the choice to call her Supergirl instead of Superwoman has created a lot of discussion.

"Being a girl isn't demeaning at all. On the other hand, there are far, far too many people in this world who can and will dismiss a 'girl' with frightening ease. A lot of these people would just as easily dismiss a woman, but it's easy to call someone a "little girl," or to tell them "don't be such a girl," etc," one Reddit user writes.
