The flagship report of the Walk Free Foundation.

Global Slavery Index

The Global Slavery Index is an initiative of the Walk Free Foundation, comprising estimates of the number of people in modern slavery in 167 countries. The index gives estimates and ratings on 3 factors:

  • The prevalence of modern slavery - in absolute numbers and in proportion to a country's population
  • The responses of governments in tackling modern slavery - in percentage scores for various government actions
  • A country's vulnerability to modern slavery - in percentage scores for various social, political and economic policies

This site contains visualizations of the latest 2014 report and the data made available on the website of the WFF.

GDP per capita and government response score: Outliers on the top-left corner of the chart show countries that should perform better combatting slavery considering their economic capacity





GDP per capita and vulnerability: As can be expected, countries with a high per capita GDP are usually less vulnerable to slavery, with some notable exceptions: Brunei, Kuwait and Qatar





Vulnerability score and government response score: In general, lower vulnerability and better government response to slavery go hand in hand. Some notable exceptions are Hong Kong, Georgia and Nigeria.
