There are still 45.8 million people subject to some form of modern slavery in the world today.
This is an estimate by the 2016 Global Slavery Index, which is based on a series of nationally representative surveys in 167 countries.
Fifty-eight per cent of that 45.8 million were estimated to live in five countries: India, China, Pakistan, Bangladesh and Uzbekistan.
The countries which were estimated to have the highest prevalence of modern slavery by the proportion of their populations, are shown in the below chart by Statista.
Of the UK’s population, 0.018 per cent were estimated to be in modern slavery, a total of roughly 11,700 people.
Of the 161 countries included in the assessment of government responses, 124 have criminalised human trafficking, 96 have National Action Plans and 150 governments provide some form of service for victims of modern slavery.
