One thing I did find really surprising and worrying here was the sheer number of students supposedly turning to sex work - one in ten - 10%! That's a remarkable statistic... so obviously I have just looked up this research to verify it. According to the "Birmingham Mail" this study was done at Birmingham University's medical school and the actual findings are that one in ten "have a friend" who has turned to this industry. Now notice how this totally isn't mutually exclusive. Whilst at University I knew about 30 people there (before Facebook really took off) so if one person works in the industry and has 30 friends who responded to this survey then they would need to ask 300 people to get this statistic for one person or one in 300 people actually working in the industry (and I wasn't the most popular!). Obviously this still isn't mutually exclusive with regards those who know a person knowing more people but still, I think it demonstrates how the information itself needs more clarification.
This reporting is backed up by the Torygraph.
Also take note that the fact it is just how many people are aware of others working in the industry, perhaps those who do no longer feel that it is something they need to hide or that there is less stigma attached - as pointed out perhaps due to The Secret Diary Of A Call Girl. If it is the case that it is just becoming more known then this would be a good thing as it would mean that the women are operating less in the shadows of the economy/society and could therefore be in a better position to seek help if needed.
