The Gender Development Index (GDI) is a composite metric published annually by the United Nations Development Programme (UNDP) in its Human Development Report. Introduced in 1995 in the landmark report on gender, the GDI was substantially revised in 2014 to its present form. It is defined as the ratio of the female Human Development Index (HDI) to the male HDI, capturing the disparity in achievement between women and men across the same three basic dimensions used in the HDI: a long and healthy life, knowledge, and a decent standard of living. The GDI therefore is not a standalone measure of women's status but a gender-disaggregated companion to the HDI, distinct from the separately published Gender Inequality Index (GII) introduced the same year in 2010.
Mechanically, the UNDP computes separate HDI values for females and males. Health is measured by life expectancy at birth (with a built-in biological adjustment giving women a five-year advantage in the goalposts). Education is measured by expected years of schooling for children and mean years of schooling for adults aged 25 and above. The standard-of-living dimension uses estimated earned income per capita, disaggregated by sex using the female share of the wage bill and labour-force participation rates. The female HDI is divided by the male HDI to yield the GDI: a value of 1.000 denotes perfect parity, values below 1 indicate male advantage, and values above 1 indicate female advantage. The UNDP further groups countries into five GDI bands (Group 1 being closest to parity) based on the absolute deviation from 1.
In recent Human Development Reports India's GDI has hovered around 0.852, reflecting a substantial gap driven overwhelmingly by the income dimension, where estimated female earned income remains a fraction of the male figure despite narrowing gaps in schooling. India is typically placed in the lower GDI groups (Group 4 or 5), underscoring that gains in girls' enrolment have not translated into commensurate economic participation. As of 2026 the UNDP continues to publish the GDI alongside the HDI, GII, and the Multidimensional Poverty Index, with high-parity performers including several Nordic and Eastern European states. Candidates should not confuse the GDI with the World Economic Forum's Global Gender Gap Index, which uses entirely different indicators and rankings.
For the examination, the GDI is tested in the social-justice and human-development segments of UPSC General Studies Paper I and Paper II, and recurs in the Indian Economy paper under inclusive-growth and HDI-related questions. Typical question angles ask candidates to distinguish the GDI from the GII, to identify the three dimensions and their indicators, to state the publishing agency and report, or to interpret what a GDI value above or below 1 signifies. Current-affairs questions link a fresh report-year value to India's relative standing. Aspirants should memorise that the GDI is a ratio (not a rank), that it shares the HDI's three dimensions, and that it is conceptually separate from the GII, which measures loss in achievement due to inequality across reproductive health, empowerment, and labour market.
Example
The UNDP's Human Development Report 2022 placed India's GDI at roughly 0.852, situating it in Group 5, the band of countries with the widest gap between female and male HDI values.
Frequently asked questions
The GDI is the ratio of female to male HDI across health, education and income, expressing gender parity in human development. The GII, introduced in 2010, instead measures the loss in achievement from inequality across reproductive health, empowerment and labour-market participation, and is reported as a separate index, not a ratio of HDIs.
