Which component is commonly used in measures of development like the HDI?

• A. Population growth rate
• B. Life expectancy, education, and standard of living
• C. Climate suitability
• D. Number of airports

Answer: (B)

Development measures often combine health, knowledge, and income to gauge progress. The HDI specifically uses life expectancy to reflect health, education metrics to show knowledge and capability, and standard of living to reflect average income. So, the option that lists life expectancy, education, and standard of living matches the components of the HDI. Population growth rate, climate suitability, and the number of airports aren’t the standard building blocks used in the HDI, as they don’t directly capture health, education, and income. This combination best reflects how development is measured in the HDI.
