How can information about who buys sex help prevent trafficking?

The University of Minnesota wanted to know who buys commercial sex in Minnesota. The answer: Most are married, middle-class white men.

The study explores why and how people buy sex, as well as who they are and where in the state they live. It was conducted by researchers at the University of Minnesota's Robert J. Jones Urban Research and Outreach-Engagement Center.

MPR's Dan Kraker covered the report last week. MPR News host Tom Weber followed up with Dr. Lauren Martin, the study's primary investigator, about how the information might be used to reduce sex trafficking.
