Nearly 30 million people around the world are living as slaves, according to a new index ranking 162 countries.
The Global Slavery Index 2013 says India has the highest number of people living in conditions of slavery at 14 million.
But Mauritania has the highest proportional figure with about 4% of its population enslaved.
The report's authors hope it will help governments tackle what they call a "hidden crime".
