Introduction
The Human Development Index (HDI) is a composite measure introduced by the United Nations Development Programme (UNDP) in its Human Development Report. It evaluates the development of countries by combining indicators of health, education, and living standards. The HDI was introduced to emphasize that people and their capabilities should be the ultimate criteria for assessing the development of a country, not just economic growth.
Historical Context
First introduced in 1990, the Human Development Index was developed by Pakistani economist Mahbub ul Haq and Indian Nobel laureate Amartya Sen. The concept revolutionized the traditional views on development which were primarily focused on income and economic growth.
Key Components of HDI
The HDI comprises three essential dimensions:
- Health: Measured by life expectancy at birth.
- Education: Assessed through two sub-components:
- Mean years of schooling for adults aged 25 years and above.
- Expected years of schooling for children entering school.
- Standard of Living: Evaluated using the Gross National Income (GNI) per capita, adjusted for Purchasing Power Parity (PPP).
Calculation and Formula
The HDI is calculated using the geometric mean of normalized indices for each of the three dimensions.
Mathematical Formula:
- Life Expectancy Index (LEI): \( \frac{\text{LE} - 20}{85 - 20} \)
- Education Index (EI): \( \left( \frac{\text{MYS}}{15} + \frac{\text{EYS}}{18} \right) \times \frac{1}{2} \)
- GNI Index (GNII): \( \frac{\log(\text{GNIpc}) - \log(100)}{\log(75000) - \log(100)} \)
Where:
- LE = Life Expectancy at Birth
- MYS = Mean Years of Schooling
- EYS = Expected Years of Schooling
- GNIpc = Gross National Income per capita (PPP $)

Importance and Applicability
The HDI provides a broadened and sophisticated perspective of development. It helps in:
- Policy Formulation: Governments can better allocate resources to improve health, education, and income.
- Comparison: Enables comparisons among countries or regions within a country to identify disparities.
- Awareness: Increases awareness about the factors impacting human development beyond mere economic metrics.
Examples
- Norway: In 2014, Norway had the highest HDI score of 0.944, reflecting high life expectancy, education levels, and income.
- Niger: Niger had the lowest HDI score of 0.348, indicating significant room for improvement in all three dimensions.
Considerations
While HDI is a robust measure, it has its limitations:
- Data Availability: In some countries, data may not be up-to-date or accurate.
- Composite Nature: A high HDI can sometimes mask inequalities within a country.
- Environmental Factors: HDI does not account for environmental sustainability.
Related Terms
- Gross Domestic Product (GDP): Measures the total economic output of a country.
- Inequality-adjusted Human Development Index (IHDI): Adjusts the HDI for inequality in distribution of each dimension.
- Gender Development Index (GDI): Compares HDI between genders.
- Multidimensional Poverty Index (MPI): Evaluates poverty by considering multiple deprivations faced by people.
Comparisons
| Measure | Focus | Components |
|---|---|---|
| HDI | Broad Development | Health, Education, Income |
| GDP | Economic Output | Economic Production |
| IHDI | Adjusted HDI | Health, Education, Income with Inequality |
| MPI | Poverty | Health, Education, Living Standards |
Inspirational Stories
- Bhutan: Known for its emphasis on Gross National Happiness, Bhutan leverages similar multidimensional assessments to prioritize holistic well-being over mere economic progress.
Famous Quotes
- “The basic purpose of development is to enlarge people’s choices.” - Mahbub ul Haq
- “Development is not about factories, dams, and bridges. It is about the people. The goal is human development, not economic development for its own sake.” - Amartya Sen
FAQs
Q: What is the purpose of HDI? A: The purpose of HDI is to provide a comprehensive measure of human development, emphasizing health, education, and income as key factors.
Q: How frequently is the HDI updated? A: The HDI is updated annually in the Human Development Report published by the UNDP.
Q: Can HDI be used to compare regions within a country? A: Yes, HDI can be adapted for sub-national assessments to compare regions within a country.

Summary
The Human Development Index is a pivotal tool in assessing and comparing the overall development of countries, focusing on health, education, and living standards. By moving beyond traditional economic measures, the HDI emphasizes the importance of a holistic approach to development, aiming for the betterment of people’s lives and capabilities.
