I tried to check the stats on this documentary but couldn't match the research. However I did find an article on OregonLive, which said that "During a one-night national sting involving 29 cities last February, law enforcement officers picked up seven underage girls involved in prostitution in Portland -- more than any other city besides Seattle." So, it does appear to be a problem in the Rose City.
