The Gender Empowerment Measure (GEM) is an index designed to measure 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, participation 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. Since it was first adopted, the GEM has been employed in several academic studies related to empowerment as a reliable metric for comparing gender empowerment across different countries. It has also faced some harsh criticisms, and many alterations and alternatives have been proposed.
