In 2005, the ILO estimated that illegal profits from forced labour amounted to more than $44bn. The UN’s global initiative to fight trafficking says people trafficking is the third-largest global criminal industry (pdf) behind drugs and arms trafficking.

The ILO estimates that people in forced labour lose at least $21bn each year in unpaid wages and recruitment fees. Given that remittances to developing countries account for more than three times the global aid budget, there is an impetus for governments to ensure that migration for work is not manipulated by traffickers.

Slavery also exists within global supply chains, generating huge profits for those who control this industry in free labour. Recent economic research has shown that forced labour has broader social and economic costs, in terms of impeding economic development and increasing or perpetuating poverty.
