A review of literature on sex trafficking since 2000 reveals that numerous articles have been published in scholarly journals but few are based on systematic primary data collection. Much of our current knowledge, including statistical estimates and characteristics of the trafficking business, derives from a handful reports issued by government and non-government agencies. With few empirical studies available, imagination seems to have filled the gaps of our knowledge. The problem was further complicated by a manifest (sometimes subtle) moral crusading agenda aimed at a deep-rooted and hotly debated social practice. Also noticeable in the literature is an increasing number of authors who have begun to challenge the empirical premises claimed by these published reports. These sceptical authors find that many articles of questionable quality have been published in peerreviewed journals, and claim that the current discourse on human trafficking is driven by mythology rather than empirical research. Rather than dwelling on gaps in our knowledge or concerns over the moral overtone in academic research, this paper seeks to raise specific research questions and explore possible field strategies that can advance our knowledge on this topic. Regardless of one's moral compass, the future of research on sex trafficking cannot become credible without a solid empirical foundation. © 2009 Taylor & Francis.
