Between 2007 and 2010 women and girls accounted for about 75% of all trafficking victims detected globally. In general, traffickers tend to be adult males, although more women are involved in trafficking in persons than in most other crimes (UNODC, 2012). The indicator shown in Figure 4.17 is based on data drawn from Gallup World Poll referring to the following question: “Do you feel safe walking alone at night in the city or area where you live?” Answers are grouped into two categories (yes/no).
