Why Do Critics Disagree with How HDI Weighs Life Expectancy?

💡 The Answer

• Critics argue that an additional year of life expectancy is valued differently between countries.
• This weighting inconsistency can skew country comparisons.
• The criticism is part of broader concerns about factor weighting in the HDI.
• In response, the UNDP introduced the inequality-adjusted HDI (IHDI) in 2010.
