What does the Human Development Index (HDI) measure and what are its three dimensions?

• A. HDI measures overall development level; dimensions are health, education, and standard of living (income).
• B. HDI measures only GDP growth.
• C. HDI measures literacy rate.
• D. HDI measures life expectancy and education only.

Answer: (A)

HDI measures overall development level by looking at three broad areas: health, education, and standard of living (income). Health is shown by life expectancy at birth, reflecting how long people can expect to live. Education combines two parts—mean years of schooling for adults and expected years of schooling for children—to capture both current attainment and future learning potential. Standard of living is represented by gross national income per capita, illustrating the resources available to people. Together, these three dimensions form a single index that goes beyond measuring wealth alone or a single indicator like literacy or life expectancy. The other options focus on only GDP growth, only literacy, or only life expectancy and education, which misses the fuller picture of development that HDI provides.
