UNODC is responsible for Sustainable Development Goals (SDG) indicator 16.2.2, which reads "Number of victims of human trafficking per 100,000 population, by sex, age and form of exploitation.”
Furthermore, UNODC has been mandated by the UN General Assembly, through the 2010 United Nations Global Plan of Action to Combat Trafficking in Persons (General Assembly resolution 64/293), to conduct research and collect suitably disaggregated data to enable proper analysis of the nature and extent of trafficking in persons.
Currently, the main research output on this topic is the biennial Global Report on Trafficking in Persons (GLOTIP) which is largely based on official national data and analyses patterns and trends of trafficking globally, regionally and at the country level.
UNODC developed this data collection questionnaire for the GLOTIP in close consultation and cooperation with Member States and relevant United Nations offices, to be distributed annually to all Member States to gather trafficking in persons related data in a uniform and standardized manner.
The GLOTIP Questionnaire must be compiled by the competent national authorities and submitted through the appropriate channels.
