This chapter presents several case studies of mixed methods projects from the UK and the USA. It highlights the impact of their research, demonstrating the usefulness of mixed methods research in criminology. In particular, there are concerns about the damage to industry and the global economy, alongside increasing recognition of links with ‘organised’ crime and terrorism. This mixed methods research set out to explore a topic that had been largely unexplored within criminology and required an approach that was interdisciplinary and iterative. In terms of exploring consumer views in relation to fashion counterfeiting and harm, the research inferences challenge focusing on a narrow understanding of crime and harm. This mixed methods project provided the first criminological exploration into understanding the consumption of counterfeit fashion. The research adopted a cross-sectional design, capturing data at a single point in time.
