Which of the following is NOT a dimension used in calculating the Human Development Index?

• A. Life expectancy at birth.
• B. Mean years of schooling.
• C. GNI per capita PPP-adjusted.
• D. Unemployment rate.

Answer: (D)

The main idea is that the HDI combines three broad dimensions to reflect human development: health, education, and standard of living. Health is captured by life expectancy at birth, since longer life expectancy signals better health outcomes. Education is represented through mean years of schooling and expected years of schooling, which together measure current attainment and future learning potential. Standard of living is reflected by GNI per capita adjusted for purchasing power parity, allowing fair comparisons of income across countries with different price levels. The unemployment rate isn’t included because the HDI focuses on overall health, education, and living standards rather than the structure or condition of the labor market; unemployment can vary with cycles and participation rates and wouldn’t provide a stable, comparable measure of development.
