Every country in the world is affected by human trafficking, as countries of origin, transit or destination - or even all three.

Trafficking often occurs from less developed countries to more developed countries.
Most trafficking is national or regional, but long-distance trafficking does occur.
Europe is the destination for victims from the widest range of destinations, while victims from Asia are trafficked to the widest range of destinations.
Sexual exploitation (e.g., sex trafficking) is by far the most commonly identified form of human trafficking. It is the most visible. Other forms of exploitation are under-reported.
A disproportionate number of women are involved in human trafficking both as victims and as culprits.
Most trafficking is carried out by people whose nationality is the same as that of their victim.
Most trafficked forced labor occurs in agriculture, construction, garments and textiles, catering and restaurants, domestic work, the provision of healthcare services, entertainment and the sex industry.
There has been a more than tenfold increase in the number of people identified as victims of modern slavery and human trafficking in London, and more than 30% of all cases nationally are discovered in the capital, according to new research.
In October [2019], the Local Government Association reported an 807% rise in the number of child victims of modern slavery and human trafficking.
