The authors contend that the most serious impediment to eliminating human trafficking is that sound data and uniform data collection systems for this transnational crime are inconsistent and/or lacking on a region-by-region and a country-by-country basis. Therefore, it is essential that authorities establish what information is needed to combat this crime and implement transnational enforcement and data sharing systems. Instead of collecting what happens to be collected, authorities should focus exclusively on critical data, data that is actually needed in order to push antitrafficking agendas, and exclude noncritical data that does not aid in enforcement. Within specific countries, singular agencies should be created to collect and analyze available data instead of the numerous governmental and nongovernmental organizations collecting data today. These singular agencies, if similarly implemented in regional countries, could share related data and truly grasp the extent of the problem, the nature of trafficking, and develop complementary enforcement strategies. If this were implemented country-by-country and region-by-region, trafficking data could be universally applied to create a truly transnational effort. Tables, endnotes, and references
