Patterns, evolution and determinants of child trafficking in Henan Province, China

Child trafficking is a serious social problem in China that has led to numerous family tragedies and drawn considerable attention. Here, we used a new database to investigate child trafficking in Henan Province in central China from a geographical perspective to help researchers better understand and explain trafficking activity. We discovered that trafficking cases involved more male than female children and that the trafficking rate was the highest for younger age groups. Child trafficking presented an interannual variation of 'rise and fall' between 1949 and 2018. An increasing trend in trafficking cases was observed after 1981, peaking in 1991, followed by a rapid decline in trafficking cases in subsequent years. Trafficking occurs more frequently during the summer than in the winter. The geographic hotspots of trafficking have continuously expanded over time from central to southwestern to southeastern Henan Province, thus revealing a triangular trafficking pattern of decentralization. The spatial pattern of child trafficking is strongly influenced by transportation. We expect these findings to provide a valuable reference for local governments in their efforts to prevent and combat child trafficking.
