According to Crimes Against Children research Centre (CCRC), the numbers of juvenile prostitutes within the United States range from 1,400 to 2.4 million, although most fall between 300,000 and 600,000.
16 children as young as 13 were rescued from the sex trade in a law enforcement operation that targeted suspected pimps who brought the victims to New Jersey for Super Bowl weekend, in February 2014.
"Prostituted children remain the orphans of America's justice system. They are either ignored or, when they do come in contact with law enforcement, harassed, arrested, and incarcerated while the adults who exploit them - the pimp and their customers - largely escape punishment," said Julian Sher, author of the book Somebody's Daughter: The Hidden Story of America's Prostituted Children and the Battle to Save Them.

Inuit babies and children are being sold by their families and are "prostituted out by a parent, family member or domestic partner", according to a recent report by Canadian Department of Justice.
The sexual exploitation of children is a deeply–rooted reality in too many Canadian homes, families and communities, according to a 2011 report by a Standing Senate Committee on Human Rights.
The committee, which started the investigation in 2009, heard that in one year there were almost 9,000 reported sexual assaults against children
(many of whom belong to aboriginal communities) in Canada. The overwhelming majority of sexual abuse goes unreported.
Social service organisations have estimated the number of trafficked Canadians to be as high as 16,000 a year, but the number of children trafficked within Canada from place to place remains uncertain due to the clandestine nature of the activity, Unicef Canada said in a statement in 2009.
