This year, the Global Gender Gap index benchmarks 156 countries, providing a tool for cross-country comparison and to prioritize the most effective policies needed to close 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. The Global Gender Gap Index measures scores on a 0 to 100 scale and scores can be interpreted as the distance to parity (i.e. the percentage of the gender gap that has been closed).
