Global Estimates of Modern Slavery: Forced Labour and Forced Marriage, 2022 (ILO, IOM, AND WALK FREE)

The 2021 Global Estimates were developed by the International Labour Organization (ILO), Walk Free, and the International Organization for Migration (IOM). The estimates are based on a jointly developed methodology: as was the case for the 2016 global estimates, the 2021 calculations are derived from multiple data sources, as no single source was sufficiently reliable. The principal sources are data from nationally representative household surveys – 68 forced labour surveys and 75 forced marriage surveys – jointly conducted by ILO and Walk Free, as well as the Counter Trafficking Data Collaborative (CTDC) anonymized case dataset on victims of trafficking collected by IOM and its partners in the process of providing protection and assistance services to trafficked persons.
