Gender Development Index
The Gender-related Development Index (GDI) is an indication of the standard of living in a country, developed by the United Nations (UN). It is one of the five indicators used by the United Nations Development Programme in its annual Human Development Report. It aims to show the inequalities between and women in the following areas: long and healthy life, knowledge, and a decent standard of living.
Methodology
Calculating the GDI involves three steps. First unit-free indices between 0 and 1 are calculated for females and males in each area. The first area is measured by life expectancy, the second by the adult literacy rate and the combined primary to tertiary gross enrollment ratio, the third by estimated earned income (at PPP US$).
Second, for each area, the pair of gender indices, are combined into an Equally Distributed Index that rewards gender equality and penalizes inequality. It is calculated as the harmonic mean of the two indices.
Finally, the GDI is the unweighted average of the three Equally Distributed Indices.
