Without first understanding the sheer complexity and pervasiveness of the issue it is impossible to measure progress.
The Global Slavery Index, first published in 2013, was developed to seeks to close the gaps in the evidence base, needed to understand the nature, scale, drivers and solutions to modern slavery. The Index draws on both random-sample, nationally representative survey research and state of the art statistical modelling to provide an estimate for prevalence of modern slavery for 167 countries.
The Index also tracks and measures steps governments have taken to address the issue, allowing a country by country comparison of effort and progress. The Index allows for clear data to be widely available and holds countries accountable for the actions they are taking to end modern slavery.
In 2017, we launched the Global Estimates of Modern Slavery with the International Labour Organization in partnership with the International Organization for Migration. The Global Estimates include estimates of forced labour and forced marriage and will be used to measure progress towards achieving Sustainable Development Goal 8.7.
Drawing on thousands of responses from face-to-face interviews, the global estimate provides further insights into the numbers behind slavery, with break-downs by region, age group and gender.
The 2018 edition of the Global Slavery Index further breaks down the data from the Global Estimates into national estimates. It measures the extent of modern slavery country by country, the drivers of modern slavery, and the steps governments are taking to respond to the issue, alongside an analysis of trade flows and data on specific products at risk of modern slavery. When considered as a set, the Global Slavery Index 2018 data provides a complex and insightful picture of the way modern slavery is impacting countries around the world.
