Child prostitution
In 2001, Dr. Richard Estes and Dr. Neil Alan Weiner estimated that in the U.S., 162,000 U.S. homeless youth are victims of commercial sexual exploitation (CVE) and that 57,800 children in homes (including public housing) are estimated to be victims of CVE.  They also estimated that 30% of shelter youth and 70% of homeless youth are victims of CVE in the United States.
