The modern definition is rather far from the original definition.
Forced labor is the biggest component of modern slavery
Many of the people characterized as modern slaves endure conditions considered "forced labor" — employed but unable to quit because their employer withholds their earnings, they owe debt to their employer or, for migrants, their employer threatens deportation.
In 2021, 28 million people were estimated to be working under forced labor conditions — an eighth of whom were children. According to the report, the majority of cases were found in the private sector, while in about 14% of cases governments imposed work requirements as a form of punishment, among other reasons. The greatest prevalence of forced labor was in Arab countries, followed by Europe and Central Asia.
The report also estimated roughly 22 million people were living in forced marriages in 2021. The number of people involuntarily wedded grew by 6.6 million compared to 2016. Nearly two-thirds of all forced marriages were found to be in Asia and the Pacific, followed by Africa, the survey found.
One of the drivers of forced and child marriages is poverty — oftentimes financially desperate families see marriage as a means to secure a stable future for their children, according to the report.
