Modern Slavery
According to American professor Kevin Bales, co-founder and former president of the non-governmental organization and advocacy group Free the Slaves, modern slavery occurs “when a person is under the control of another person who applies violence and force to maintain that control, and the goal of that control is exploitation”. The impact of slavery is expanded when targeted at vulnerable groups such as children. According to this definition, research from the Walk Free Foundation based on its Global Slavery Index 2018 estimated that there were about 40.3 million slaves around the world. In another estimate that suggests the number is around 45.8 million, it is estimated that around 10 million of these contemporary slaves are children. Bales warned that, because slavery is officially abolished everywhere, the practice is illegal, and thus more hidden from the public and authorities. This makes it impossible to obtain exact figures from primary sources. The best that can be done is to estimate based on secondary sources, such as UN investigations, newspaper articles, government reports, and figures from NGOs.
