Stats on Child Sexual Abuse

Following a link on Ruth Gledhill's blog I came across a page of statistics with one statistic I don't think I have seen before. The statistics are for the UK, and look at her original post if you would like to follow up some other links, particularly from the three major insurers of US Protestant Churches and claims for sexual abuse. Anyway, on the link mentioned above, the last entry says:

Very few children (less than 1%) experienced abuse by professionals in a position of trust, for example a teacher, religious leader or care/social worker.

(Here is the link.)
