The Gender-related Development Index (GDI) was introduced in 1995 in the Human Development Report written by the United Nations Development Program in order to add a gender-sensitive dimension to the Human Development Index. The GDI takes into account not only the average or general level of well-being and wealth within a given country, but also how this wealth and well-being is distributed between different groups within society, especially between genders.[87] However, feminist economists do not universally agree on the use of the GDI and some offer improvements to it.[88]
