Which of the following is NOT a component of the Human Development Index (HDI)?

Which of the following is NOT a component of the Human Development Index (HDI)?

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

Answer: (A)

The essential idea is that the HDI measures human development through health, education, and standard of living. Population density doesn’t fit into those dimensions because it’s a spatial statistic—how crowded an area is—not a direct measure of a society’s health, learning, or income per person. Health is captured by life expectancy at birth, education by mean years of schooling, and living standards by gross national income per capita. These three together reflect the everyday conditions that people experience. Population density can influence development in various ways, but it does not itself indicate how healthy people are, how long they live, how much education they receive, or how much income is available per person, which is why it isn’t part of the HDI.
