Nearly 80% of human trafficking is for sex, and 19% for labor exploitation.  Sex traffickers often recruit children because not only are children more unsuspecting and vulnerable than adults, but there is also a high market demand for young victims. Traffickers target victims on the telephone, on the Internet, through friends, at the mall, and in after-school programs.  Human traffickers often use a Sudanese phrase “use a slave to catch slaves,” meaning traffickers send “broken-in girls” to recruit younger girls into the sex trade.  Airports are often used by human traffickers to hold “slave auctions,” where women and children are sold into prostitution. 
Out of nearly 25,000 runaway youth reported, an estimated one out of seven were likely child sex trafficking victims. Of those, 88% were in the care of social services when they went missing.
