Human Development Index (HDI). The HDI is a multidimensional measure of the economic development of an economy. The HDI measures a mix of income, health and education.
The HDI is an index combining:
- Measured by GDP per capita at Purchasing Power Parity (PPP), what the average citizen can afford.
- Measured by life expectancy at birth.
- Measured by the adult literacy rate and educational enrolment rates.
The HDI measures a mix of income, health and education. These three measures are given equal weighting. The HDI lies between 0 and 1. A country is more developed the higher its HDI score is.
