Which index is widely used to compare development levels by combining life expectancy, education, and income?

• A. Maquiladoras
• B. EPZs
• C. Structuralist Theory
• D. Human Development Index (HDI)

Answer: (D)

The development metric that combines life expectancy, education, and income into a single score is the Human Development Index. It blends health, measured by life expectancy at birth; education, captured by mean years of schooling and expected years of schooling for children; and standard of living, represented by gross national income per capita. These three dimensions are normalized and combined to produce a single index that lets us compare how well countries are doing in promoting human development, not just how rich they are. This broader view explains why the HDI is widely used: it reflects overall well-being and potential for a decent life, beyond GDP alone. The other terms refer to factories, zones, or theories and do not function as an index that aggregates these three development indicators.
