What is GEM measure?

The Gender Empowerment Measure (GEM) is an index designed to measure of gender equality. GEM is the United Nations Development Programme's attempt to measure the extent of gender inequality across the globe's countries, based on estimates of women's relative economic income, participations in high-paying positions with economic power, and access to professional and parliamentary positions. It was introduced at the same time as the Gender-related Development Index (GDI) but measures topics like empowerment that are not covered by that index.
