The Global Social Mobility Index is an index prepared by the World Economic Forum. The inaugural index from 2020 ranked 82 countries and has not been updated since. The Index measures social mobility holistically through 5 determinants. The findings from the index were then used in the World Economic Forum's Global Social Mobility Report 2020, which provided recommendations for governments and businesses. Researchers have used the index to analyze income inequality and have determined reasons for countries to improve social mobility.

The Global Social Mobility Index was established by the World Economic Forum in 2020 in light of the changes caused by globalization and technological advancement. The results and findings of the index are summarized in the Global Social Mobility Report 2020. The index differs from previous measures of social mobility because it uses a more holistic methodology, ultimately measuring the causes of social mobility. Previous measures focused on comparing intergenerational incomes. These comparisons drew data from different time periods, and thus it was more difficult to draw clear conclusions about the present.

The World Economic Forum measured social mobility through five determinants: health, education, technology, work, and institutions. These five determinants are measured by the following ten pillars, each with its own set of parameters.

Pillar 1: Health

Pillar 2: Education Access

Pillar 3: Education Quality and Equity

Pillar 4: Lifelong Learning

Pillar 5: Technology Access
