HDI Calculator: Health, Education, and Income Index

The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development: a long and healthy life, being knowledgeable, and having a decent standard of living. The HDI is the geometric mean of normalized indices for each of the three dimensions.

Historical Background

The HDI was introduced in 1990 by the United Nations Development Programme (UNDP) to provide a more comprehensive measure of human development than those based on income per capita alone. It recognizes that individuals value achievements in many aspects of their lives, not just income.

Calculation Formula

The HDI is calculated using the following formula:

\[ \text{HDI} = \sqrt[3]{\text{Health Index} \times \text{Education Index} \times \text{Income Index}} \]

• Health Index: Based on life expectancy at birth.
• Education Index: A combination of mean years of schooling and expected years of schooling.
• Income Index: Based on gross national income (GNI) per capita.

Example Calculation

For illustrative purposes, assume:

• Health Index: 0.85
• Education Index: 0.80
• Income Index: 0.75

\[ \text{HDI} = \sqrt[3]{0.85 \times 0.80 \times 0.75} \approx 0.800 \]

Importance and Usage Scenarios

The HDI is used by policymakers and scholars as a tool to assess and compare the level of development of various countries and to gauge the impact of economic policies on quality of life.

Common FAQs

   • The HDI is reported annually in the Human Development Report published by the UNDP.

3. Can the HDI be used to compare countries over time?

   • Yes, the HDI can track the development progress of countries over time, though it's important to consider changes in methodology when making long-term comparisons.
