GSI-2016-Full-Report

METHODOLOGY
HOW DID WE MEASURE PREVALENCE?
Measuring the number of people in modern slavery is a difficult undertaking due to the hidden nature
of this crime and low levels of victim identification. Since 2014, we have conducted 25 surveys with
the international research-based agency Gallup [2] through their World Poll, interviewing over 28,000
respondents in 52 languages. This year we also conducted state-level surveys in India. When these
are included, we have interviewed over 42,000 respondents in 53 different languages. The prevalence
estimates in the Index are based on data from these surveys, the results of which have been extrapolated
to countries with an equivalent risk profile.

HOW DID WE MEASURE VULNERABILITY?
The Global Slavery Index includes a model of 24 variables which affect vulnerability to enslavement.
These include:
• Civil and political protections
• Social, health and economic rights
• Personal security
• Refugees and conflict
HOW DID WE MEASURE GOVERNMENT RESPONSES?
The final component of the Index is a score of 161 [3] governments' responses based on an assessment
of 98 indicators of good practice, taking into account factors such as whether each country has the
necessary laws in place, provides support to victims, and ensures application of labour standards
to vulnerable populations. Research for this aspect of the Index involved a partnership between the
Walk Free Foundation’s research team and DataMotivate, an organisation that provides training and
employment for survivors of modern slavery in the Philippines.
A summary of the methodology is in Appendix 2, and a detailed methodology paper is available online.
