In September 2017, UNODC (Crime Research Section) and the Dutch National Rapporteur on Trafficking in Human Beings launched a national estimate of the number of victims of trafficking in persons in the Netherlands, by sex, age, nationality (Dutch or non-Dutch) and form of exploitation. Produced with the multiple systems estimation (MSE) methodology, the publication of this estimate marks a leap forward in trafficking research and will pave the way for further studies in other countries in the years to come. Read the Research Brief (pdf).  

NEW: In close cooperation with the countries concerned, and in partnership with Walk Free Foundation, UNODC has undertaken MSE studies for Ireland, Romania and Serbia. Please click on the country names to read/download (pdf files).


Looking for the UNODC Global Study on Smuggling of Migrants ?

The 2016 UNODC Global Report on Trafficking in Persons is the third of its kind mandated by the General Assembly through the 2010 United Nations Global Plan of Action to Combat Trafficking in Persons. It covers 136 countries and provides an overview of patterns and flows of trafficking in persons at global, regional and national levels, based primarily on trafficking cases detected between 2012 and 2014. As UNODC has been systematically collecting data on trafficking in persons for more than a decade, trend information is presented for a broad range of indicators.

The thematic chapter of the 2016 edition of the Global Report looks at how migrants and refugees can be vulnerable to trafficking in persons, en route or at destination. It also analyses the particular condition of people escaping war, conflict and persecution.

Most countries have passed legislation that criminalizes trafficking in persons as a specific offence; many have done so recently. The Global Report shows that there is a relation between how long a country has had proper trafficking legislation on its books, and how many convictions it reports. Countries with longer-standing legislation record, on average, more convictions. That said, the overall criminal justice response to trafficking in persons, which has historically been very weak, has not improved significantly.

The Country Profiles, available below, present national-level data for the countries covered by this edition of the Global Report.
