The Human Development Index (HDI) published by UNDP is constructed from three dimensions of development. Which set of components correctly lists these dimensions?
- A Life expectancy at birth, literacy rate and infant mortality rate
- B A long and healthy life, knowledge (education), and a decent standard of living ✓
- C Per capita income, access to safe water and sanitation coverage
- D Physical quality of life, gender equality and environmental sustainability
Correct answer: B. A long and healthy life, knowledge (education), and a decent standard of living
Explanation
HDI combines a long and healthy life measured by life expectancy at birth, knowledge measured by mean years of schooling for adults and expected years of schooling for children, and a decent standard of living measured by Gross National Income per capita. Option A mixes PQLI-style indicators such as literacy and infant mortality, option C lists basic amenities, and option D resembles composite indices covering equity and environment, none of which enter the HDI formula.
