The frequency of child sex abuse is a true epidemic. Since at least 2000, the U.S. Department of Justice has reported that some 67 percent of all sexual assaults are committed against victims under 18 years old. The U.S. Department of Health and Human Services reports confirmed child sexual abuse cases number approximately 58,000 per year in recent years. Unreported child sexual assaults are estimated at 80 percent. Most Americans who are victims of sex trafficking come from our nation's own foster care system. It's a deeply broken system that leaves thousands vulnerable to pimps as children and grooms them for the illegal sex trade as young adults. Most people don't know about our nation's foster care to sex trafficking pipeline, but the facts are sobering. The National Center for Missing and Exploited Children (NCMEC) found that "of the more than 18,500 endangered runaways reported to NCMEC in 2016, one in six were likely victims of child sex trafficking. Of those, 86 percent were in the care of social services when they went missing." As NCMEC's CEO told Congress in 2013, "Children in foster care are easy targets for pimps ... [they] are the most susceptible to the manipulation and false promises that traffickers use to secure their trust and dependency." Child welfare systems can, but often do not, prevent that reality for children. Pimps rely on that. I have seen all of this up close as an attorney who represents children abused in foster and group home care.
