In the Human Development Index, the standard of living is proxied by which metric?

• A. GDP per capita.
• B. GNI per capita.
• C. Unemployment rate.
• D. Life expectancy.

Answer: (B)

The standard of living in the HDI is represented by income available to residents, captured as GNI per capita in purchasing power parity (PPP) terms. This combines all income residents receive—whether from domestic production or abroad—and divides it by the population, showing the resources people actually have to sustain their lives. The PPP adjustment makes comparisons fairer by reflecting what money can buy in different countries, rather than just nominal amounts. GDP per capita, by contrast, looks only at what a country produces domestically and can miss income residents receive from outside or be skewed by foreign ownership. Unemployment rate and life expectancy measure different aspects (labor market conditions and health), not the overall income resources households can use for living standards. So, GNI per capita in PPP terms is the best proxy for standard of living in the HDI.
