Which description best defines the Human Development Index (HDI)?

• A. A measure of economic wealth only.
• B. The total population's median age.
• C. The inflation rate over a year.
• D. A composite development indicator, combining GNP per capita, number of years schooling and life expectancy.

Answer: (D)

The main idea behind the HDI is that development is multidimensional, not just about money. It combines health, education, and living standards into one measure. Health is captured by life expectancy at birth, showing how long people live and how well they are supported healthwise. Education is represented by two components: mean years of schooling for adults and expected years of schooling for children, reflecting access to knowledge and learning opportunities. Living standards are reflected by income per person, typically measured as GNI (or GNP) per capita adjusted for purchasing power parity, indicating the resources available to people in a country. The option that describes a composite development indicator combining income per person, years of schooling, and life expectancy best matches the HDI because it encapsulates these three dimensions in one index. The other descriptions focus on wealth alone, age structure, or inflation, which do not capture the broader, multidimensional nature of human development.
