How is the HDI typically presented in development metrics?

• A. It combines life expectancy, education, and income per capita into a single composite index.
• B. It is computed as the average of GDP, literacy, and housing quality.
• C. It uses only health indicators.
• D. It uses stock market performance.

Answer: (A)

The HDI is a single summary measure built from three key areas of development: health, education, and standard of living. It uses life expectancy at birth to represent health, education through measures like expected years of schooling and mean years of schooling, and income per capita to reflect living standards. These parts are normalized and combined into one score on a 0-to-1 scale, giving a straightforward way to compare overall development across countries.

This isn’t about averaging GDP, literacy, and housing quality, and it doesn’t rely on only health indicators or stock market performance. Those would miss important dimensions of development that the HDI explicitly includes.
