Human Development Index
The Human Development Index (HDI) is a number from 0 to 1 (higher is better) used to compare different countries. It is published by United Nations Development Programme. It is used to rank countries into different groups for example developed and developing countries.
- Life expectancy at birth. This is used to see how healthy the people in one country are. It assumes that healthier people live longer on average.
- Literacy is used to look at how educated people are, for example how many adults can read and write. One third of this is the gross enrollment ratio, which measures how many of children of schooling age attend school.
