This year’s edition of the report benchmarks 149 countries on their progress towards gender parity on a scale from 0 (disparity) to 1 (parity) across four thematic dimensions—the subindexes Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment—and provides country rankings that allow for effective comparisons across and within regions and income groups. The rankings are designed to create global awareness of the challenges posed by gender gaps, and the opportunities created by reducing them. The methodology and quantitative analysis behind the rankings are intended to serve as a basis for designing effective measures for reducing gender gaps. The methodology of the Index has remained stable since its original conception in 2006, providing a basis for robust cross-country and time-series analysis.
