The HDI is a composite index used by the United Nations to assess countries’ progress in three fundamental dimensions of human development: a long and healthy life, knowledge, and a decent standard of living.
The Three Dimensions & Indicators
| Dimension | Indicator |
|---|---|
| Health | Life expectancy at birth. |
| Education | Mean years of schooling and expected years of schooling. |
| Standard of Living | Gross National Income (GNI) per capita (PPP $). |
High-Yield Notes:
- Range: The HDI score ranges from 0 to 1, with higher values indicating higher human development.
- Comparison: Unlike the PQLI, the HDI incorporates income, providing a more holistic view of development that acknowledges both social and economic factors.
- Limitations: It does not directly reflect inequality, poverty, gender disparity, or human security (which are addressed by supplementary indices like the Inequality-adjusted HDI or Gender Development Index).
