The Gender-related Development Index (GDI) is an indication of the standard of living in a country, developed by the United Nations (UN). The standard of living refers to the quality and quantity of goods and services available to people and the way these goods and services are distributed within a population The United Nations ( UN) is an International organization whose stated aims are to facilitate cooperation in International law, International security It is one of the five indicators used by the United Nations Development Programme in its annual Human Development Report. The Human Development Report (HDR is an annual milestone publication by the United Nations Development Programme (UNDP It aims to show the inequalities between men and women in the following areas: long and healthy life, knowledge, and a decent standard of living.

## Methodology

Calculating the GDI involves three steps. Step 1: Unit-free indices between 0 and 1 are calculated for females and males in each of the following areas:

1. life expectancy,
2. education (the adult literacy rate and the combined primary to tertiary gross enrollment ratio),
• Female Life Expectancy Index = $\frac{\mbox{female life expectancy} - 27.5} {87.5-27.5}$
• Male Life Expectancy Index = $\frac{\mbox{male life expectancy} - 22.5} {82.5-22.5}$
• Female & Male Education Indices = $\frac{2} {3}\frac{\mbox{adult literacy rate of gender}} {100}+\frac{1} {3}\frac{\mbox{gross enrollment rate of gender}} {100}$
• Female & Male Income Indices = $\frac{log(\mbox{earned income of gender}) - log(100)} {log(40,000)-log(100)}$

Step 2: 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.

• Equally Distributed index = $\left(\frac{\mbox{female share of population}}{\mbox{female-index}}+\frac{\mbox{male share of population}}{\mbox{male-index}}\right)^{-1}$

Step 3: The GDI is the unweighted average of the three Equally Distributed Indices: Equally distributed life expectancy index, Equally distributed education index, Equally distributed income index
