This has to do with statistics. The subcommittee report I mentioned that came out today reports that NGOs and state-level actors are “working toward eliminating sex trafficking using different definitions and a divergent method of data collection.” In 2010, Stats Canada's centre for crime statistics also said that “very few organizations or government departments systematically collect data on human trafficking”. It is eight years later. Is that still the case? Is there still divergent data collection? Is this a problem or not? I am asking anyone who might know.
