In a world with increasing access to data, indices serve a purpose: to allow for complex concepts to be conceptualized in a single data point and compared across different contexts.
It was with this in mind that we created the Girls’ Opportunity Index in partnership with World Vision. World Vision sought to explore the relationship between the opportunities a girl was provided and child marriage rates. The activity involved only secondary national-level data and the creation of an index seemed perfect to all for country-to-country comparisons.
