8% of students involved in the sex trade: The Times

I’m having a hard time honestly believing that the number of "students" involved in the sex trade is even close to that high, but according to an article put out by The Times in UK today, this is the case:

"A second survey in 2006 showed that number had again climbed to six per cent and with a third study currently underway, more than eight per cent of the current student population is expected to be participating in sex work."
