Name a composite indicator used to measure development and list its three components.

• A. The Gross Domestic Product (GDP) per capita; components: total GDP and population.
• B. The Human Development Index (HDI); components: life expectancy at birth, education (mean years of schooling and expected years of schooling), and gross national income per capita (GNI PPP).
• C. The Literacy Rate; components: reading ability, writing ability, numeracy.
• D. The Countdown Index; components: birth rate, death rate, migration.

Answer: (B)

A composite indicator combines several different measures into one overall score to give a broader view of development. The Human Development Index is a classic example because it blends three key areas: health, education, and living standards. Its components are life expectancy at birth (health), education, which includes mean years of schooling and expected years of schooling, and gross national income per capita adjusted for purchasing power (income). Together, these parts show how long people live, how well they’re educated, and how rich the typical person is, giving a more rounded picture than any single metric. Other options aren’t composite indicators in the same way or don’t cover multiple development dimensions. GDP per capita, for instance, is purely an economic measure. Literacy rate focuses only on education and doesn’t include health or income. The Countdown Index isn’t a standard, widely used development measure with a fixed three-part structure.
