The lack of reliable and comparable data on trafficking in human beings remains one of the main obstacles in effectively preventing and combating trafficking in human beings as well as protecting and assisting victims. IOM and the Austrian Federal Ministry of the Interior have recently published the Guidelines for the Collection of Data on Trafficking in Human Beings (THB), Including Comparable Indicators, developed to create the necessary basis for an improved collection, comparison and sharing of data on THB. The Guidelines seek to enhance the capacity of the national authorities to collect and share data as well as to contribute to EU-wide efforts to enhance data collection and to foster cooperation among EU Member States.
