What is modern slavery? 

Slavery did not end in the 19th century. Today there are more slaves in the world than ever before. Slavery is a complex crime that is notoriously hard to measure. According to the most widely used current estimates around 40.3 million people are enslaved. 

A slave can be defined as someone who is under the power of another who exercises the rights of ownership over them. This can take many forms from sexual exploitation to forced labour or organ trafficking. The enslaver's power can be manifested physically or psychologically, and it can take the form of emotional abuse, control of passports and other documents, physical threats or other threatening behaviour. 

Modern slavery can affect someone of any gender, race or age. However, it most commonly affects those made vulnerable by insufficient access to opportunities, education, healthcare or sanitation. Poverty is the biggest driver.  

What is the link with human trafficking?

Human trafficking is often included when people use the term 'modern slavery', but it would be wrong to conflate them. Human trafficking has its own legal definition: the "recruitment, transportation, transfer, harbouring or receipt of persons, by means of the threat or use of force or other forms of coercion, of abduction, of fraud, of deception, of the abuse of power or of a position of vulnerability or of the giving or receiving of payments or benefits to achieve the consent of a person having control over another person, for the purpose of exploitation".
