Human Development Index (HDI)
The Human Development Index (HDI) is a composite measure combining three dimensions: health (life expectancy at birth), education (years of schooling and expected years), and living standards (GDP per capita). It provides broader development assessment than income alone.
Real World
Norway consistently tops the HDI rankings with a score above 0.96, reflecting high life expectancy, near-universal literacy, and strong per capita income — contrasting sharply with South Sudan's score of around 0.38.
Exam Focus
Always state at least two limitations of HDI in evaluation paragraphs — inequality blindness and data reliability are the most mark-scheme-friendly.
