Which metric is most associated with measuring overall development levels across countries?

• A. FEC
• B. GNP per capita
• C. HDI
• D. GATT

Answer: (C)

Measuring development levels across countries calls for a metric that combines multiple dimensions of well-being. The Human Development Index does just that by blending health, education, and income into a single measure. It uses life expectancy to reflect health and longevity, education indicators to show knowledge and skills, and gross national income per person to capture living standards. This multi-faceted approach provides a broader view of development than income alone, which is what makes it the best choice for gauging development across countries.

In contrast, income-focused measures like GNP per capita assess only average economic output per person and don’t capture health or educational attainment. Trade agreements like GATT measure international trade rules, not development outcomes. The first option (FEC) isn’t a standard development metric. So the Human Development Index is the most appropriate tool for comparing overall development levels.
