Abstract

Law enforcement data are a promising and largely untapped resource for academic research into human trafficking. Better use of such data can help inform and expand an evidence-based approach to counter-trafficking policy and practice. Authored by academics and a senior law enforcement practitioner, this chapter provides rare and important insights into the theoretical, practical, legal, and ethical considerations around using law enforcement data in human trafficking research. Its discussions should prove useful to researchers, practitioners, and policy-makers interested in understanding and tackling human trafficking more effectively. The chapter begins with a critical appraisal of the human trafficking literature, highlighting particular gaps, imbalances, and weaknesses. The stage is then set to explore the utility and applications of a long-neglected but empirically rich source of data on human trafficking: those that law enforcement agencies generate and/or hold. The limitations of law enforcement data are made explicit, and their benefits are explored, with reference to relevant human trafficking studies and innovative research into other crimes. Key considerations are addressed around the actual process of using law enforcement data, drawing on the authors’ experiences as researchers and a research enabler and a data provider. This section is informed in particular by four recent human trafficking studies in which the authors were involved, all of which used sensitive and hard-to-access law enforcement data. These innovative studies spanned both small- and large-scale datasets; qualitative, quantitative, and mixed-method enquiries; internal and international trafficking movements; and some of the main variants of human trafficking: sex trafficking, trafficking for domestic servitude, and labor trafficking across diverse licit and illicit labor markets.
