A report out this week will debunk the myth that child sexual exploitation is the preserve of certain ethnic groups, saying that perpetrators can come from any background.
Deputy children's commissioner Sue Berelowitz is carrying out a two-year government inquiry into the issue.
Leaked copies of the interim report due out on Wednesday suggest that the exploitation could be carried out by men of all backgrounds with no emphasis on any particular ethnic group.
Launching the inquiry last year Ms Berelowitz said: "The emerging demographic of the children and perpetrators involved is very diverse and seems to reflect the local demographic of where the abuse is taking place."
