世論 What Japan Thinks

This Japan Times article (well, it’s just a translation, the original weekly tabloid is more to blame) on kiddie fiddling teachers features the following frustratingly incomplete statistic.

Of the 166 cases, 46.4% of the victims were students, while 2.4% were graduates.

Eh? What happened to the other 51.2%? Do they mean that 46.4% were current students of the kiddy fiddling teacher? This sort of hopelessly incomplete datum point just leaves me all hanging in the air!
