Mauritania has the highest prevalence of modern slavery in the world, according to the inaugural Global Slavery Index, with 14 other African countries also among the 20 worst performers.
The Index, which will be published annually, is the first of its kind and gives the most accurate and comprehensive measure of the extent and risk of modern slavery, country by country, currently available.
Mauritania is ranked worst on the Index, with the highest estimated proportion of its population enslaved of any country in the world. The West African country, with its deeply entrenched system of hereditary slavery, is thought to have an estimated 150,000 slaves in a population of only 3.8 million. Benin, Cote d’Ivoire, Gambia and Gabon follow Mauritania in the top ten of the Index.
