The 2016 global slavery index, funded by Forrest’s Walk Free Foundation, says 45.8 million people are trapped in some form of slavery.
Walk Free said slavery is found in all 167 countries in the index, with India home to 18.4 million slaves. This year’s index also claims that over half of the 45.8 million people living in modern slavery are in five countries: India, China, Pakistan, Bangladesh and Uzbekistan.
The International Labour Organisation (ILO) estimates that 21 million people are trapped in forced labour and other forms of modern slavery.
The index says it hopes to work with the ILO to provide a single set of global estimates.
