Which HDI component most directly reflects health outcomes?

Which HDI component most directly reflects health outcomes?

• A. Expected years of schooling
• B. Gross National Income per capita
• C. Life expectancy at birth
• D. Mean years of schooling

Answer: (C)

Life expectancy at birth directly reflects health outcomes. It measures how long people are expected to live, capturing the overall health of a population, including mortality risks, disease burden, and access to medical care. This makes it the clearest indicator of health within the HDI framework. The other two measures relate to education and economic resources. Years of schooling indicate educational attainment, which influences health indirectly through knowledge and opportunities, not the actual health status itself. GNI per capita represents wealth and the capacity to fund health and other services, but it is an economic input, not a direct health outcome.
