Which indicator best measures a blend of health, education, and income in development?

• A. GDP per capita.
• B. Literacy rate.
• C. The Human Development Index.
• D. Terms of trade index.

Answer: (C)

In development, you want a single measure that reflects people’s well‑being across health, education, and income. The Human Development Index does this by combining three dimensions: health (life expectancy at birth), education (mean years of schooling and expected years of schooling), and standard of living (GNI per capita, PPP-adjusted). These are rolled into one score that ranges up to 1, so you can compare countries and track progress over time. It captures more than just money because it includes how long people live and how much schooling they receive, not just how much income exists. GDP per capita looks only at income and misses health and education. The literacy rate covers education but not health or income. The terms of trade index relates to trade terms and economic position, not living standards or development overall.
