Measuring Slavery

Measuring SlaveryOur research is helping to end contemporary global slavery in our lifetime. There are 46 million people enslaved around the world today. But we are at a tipping point: there is a global political commitment to ending slavery by 2030.

The issue

Only by measuring and understanding the scale of slavery can we effectively tackle it. Since 2013, the Walk Free Foundation has published the annual Global Slavery Index (GSI).

The world's only big data intervention into contemporary slavery, the GSI is a country by country estimation of slavery's prevalence and the adequacy of response in 167 countries.

The research

We help to refine the GSI's global metrics, further develop the data collection and analysis methodology to bring greater validity and reliability, incorporate new data on factors that make people vulnerable to enslavement, and develop new methodologies for particularly challenging countries that build on current methods.

We also dig deep into the GSI's unanalysed data to conduct in-depth analysis around key themes, for example the relationship between slavery's prevalence and internal conflict, or between women’s physical integrity and rates of enslavement.

The impact

The Global Slavery Index provides a map, country by country, of the estimated prevalence of modern slavery, together with information about the steps each government has taken to respond to this issue. This information allows an objective comparison and assessment of both the problem and adequacy of the response in 167 countries.
