ABSTRACT
The research community on human trafficking has grown significantly in the past two decades, and consequently produced a large body of literature. There is much to celebrate – the volume of scholarship and advocacy literature have exerted sizable influence on policy making and funding priorities. More specifically, much progress has been made on measurement and prevalence estimation techniques, and some consensus is forming gradually on the common measures and counting rules to quantify human trafficking activities. Another major change is the growing rigors in outcome evaluation. Although still few and far between, funding agencies increasingly request an assessment of program impact through randomized controlled trials in different parts of the world. This paper provides an overview of the significant development in three areas: (1) the development of common measures to define what counts as human trafficking in empirical settings; (2) the development of strategies to estimate prevalence of human trafficking activities using primary as well as secondary data; and (3) the growing demand for rigorous evaluation for anti-trafficking interventions. Suffice it to say, research on human trafficking has passed its infancy and is now at an adolescent stage where exciting projects, ideas and field strategies are multiplying rapidly, as seen in the collection of select papers in this special issue.
