Our Partner

Walk Free Foundation

Walk Free Foundation is a global organization with a mission to end modern slavery in our generation. A key aim is to generate the highest quality research to fuel a global conversation about modern slavery and drive change.

The Impact


The Walk Free Foundation and Gallup partnered to create the Global Slavery Index, which as of 2018 has expanded to study modern slavery in nearly 50 countries. Within one month of the 2018 release, the index achieved more than 100,000 Twitter impressions.

The Challenge

Measure the scale of a hidden crime

Most of the victims of modern slavery are hiding in plain sight. That's why Walk Free Foundation partnered with Gallup to discover the real number of people who are trapped in this situation around the world, and set a plan in motion. Because of their work so far, we know today that number stretches higher than 40 million.

Walk Free Foundation's goal is to work with governments and industries of the top 10 economies of the world to enact laws to ensure organizations are held accountable for modern slavery in their supply chains and to empower independent oversight.


Our Approach

Create a new method to give silent victims a voice

Gallup, Walk Free Foundation and an advisory group of global experts devised an innovative methodology to reach this vulnerable population. As of 2018, Gallup has conducted 54 nationally representative studies in 48 countries with more than 70,000 adults. The results give the millions of victims of this crime a voice.

Over 40 million people are victims of modern slavery worldwide.

Ignite a global conversation

The Global Slavery Index has gained worldwide visibility and fueled a global conversation to change the world. With the launch of the 2018 index, an estimated 5 billion were reached through media coverage from top-tier media outlets such as CNN, The New York Times, BBC, The Washington Post, The Economist, Reuters, Al Jazeera,The Guardian, USA Today, Newsweek, Daily Mail and The Daily Telegraph. Global leaders and philanthropists including Bill Gates, Hillary Clinton, the World Economic Forum, Russell Crowe, Ryan Gosling, UN Women and Sir Richard Branson have endorsed the Global Slavery Index.
