Even with some reporting disruptions, the scale of modern slavery remains staggering. In 2023, U.S. authorities alone logged $398 million in losses tied to human exploitation scams, while forced labor risk in global supply chains reaches an estimated 10% of goods upstream. This post connects those warning signs to the wider trafficking picture worldwide, including what changed between 2019 and 2021 and why the patterns still matter.
Key Takeaways
- In 2021 (the most recent year cited in UNODC’s early warning/detection coverage), UNODC notes a decline in reported trafficking cases compared with 2019 due to COVID-19 disruptions, with case reporting reductions reflected in the GLOTiP 2022 analysis.
- In the EU, 45% of criminal justice decisions in trafficking in human beings cases were convictions (share reported in Eurostat’s trafficking statistics explainer).
- The Global Slavery Index (2018) estimated prevalence of forced labour at 24.9 million people and forced marriage at 2.0 million, totaling modern slavery at 26.9 million (figures presented in the report).
- ILO estimates 152 million people are working in child labour in exploitative conditions, indicating vulnerability overlap with forced labour risks (ILO child labour estimates in ILO publication).
- 6.1 million children were in forced labor conditions in 2021
- 4.2 million verified victims of modern slavery were identified by Walk Free research in 2019 (cumulative research verification result used in the report methodology)
- In 2022, U.S. government anti-trafficking task forces conducted 1,700+ operations (HHS OTIP annual reporting)
- In 2021, the U.S. Office on Trafficking in Persons provided services to 10,000+ victims (HHS OTIP annual reporting)
- Up to 1.6 million children were estimated to be at risk of forced labor in supply chains in agriculture sector (OECD estimate used in due diligence briefs)
- In 2023, U.S. CBP issued 14 Withhold Release Orders connected to forced labor allegations (WRO count)
- In 2022, the OECD estimated that 10% of global goods are linked to forced labour risk in at least one upstream stage (OECD due diligence model output)
- In 2019, UNICEF reported 1 in 5 children worldwide were engaged in child labour (UNICEF global figure)
- In 2016-2020 estimates, 27.4% of child labourers were in hazardous work (UNICEF/ILO harmonized estimate)
- In 2019, a systematic review estimated that 75% of victims of human trafficking experience psychological harm during exploitation (systematic review quantitative synthesis)
- In 2017, a peer-reviewed study found that 20.1% of trafficking victims surveyed in shelters reported coercion through debt bondage methods
COVID disrupted reporting, but modern slavery persists at massive scale, with millions affected worldwide.
