One person who has attempted an estimate is Dr Michael Seto, a clinical and forensic psychologist at the Royal Ottawa Healthcare group.But Seto stresses that 5% was an upper estimate, and that the studies were limited in what they revealed.
In 2008 he wrote a book (Pedophilia) in which he put the prevalence of paedophilia in the general population at 5%.
The figure was based on surveys conducted in Germany, Norway and Finland in which men were asked whether they had ever had sexual thoughts or fantasies about children or engaged in sexual activity with children.
