On Percentages

Joni Bolter in the Seattle Times suggests that we should start paying attention to men, in regards to their education. Acknowledging that gains in female matriculation and graduation rates were significant and worthy of praise, Bolter suggests that men are slipping behind and that this might be cause for concern. She points out:

For many years at the University of Washington graduation, the university president, in his welcoming remarks, offered a tally of female graduates in various fields. After the female percentages were announced, Husky Stadium would erupt in a roar of cheers. Many years, similar figures for male students were not offered.

Given that there are only two categories, female and male graduation percentages, isn't the male percentage implied whenever the female percentage is offered?
