In past years, considerable research has been undertaken on the role of female sex workers (FSWs) in the transmission of HIV infection. FSWs have been seen as a major “source” of infection, and consequently, have been extensively targeted to prevent its spread. There is, however, a gap in our understanding of the dynamics of sex work, sex workers\u27 patterns of mobility, and the relationship of such mobility with risk of HIV infection and gender-based violence. The Population Council collaborated with its local partner, TNS, to carry out a study in Tamil Nadu to examine the patterns of mobility of FSWs and to study its links with HIV risk. The goal was to provide research-based evidence to inform the formulation of policies and to improve the implementation of programs. Results presented here describe the patterns and drivers of sex workers\u27 migration at their destination points, intermediate points, and points of origin, and their connection to high-risk activities in Tamil Nadu
