Which factor is included in the human development index (HDI)?

The Human Development Index (HDI) includes the following factors:

1. Life expectancy at birth: It measures the number of years an individual is expected to live at birth, indicating health and access to healthcare.

2. Education: It takes into account two indicators:
a. Mean years of schooling: It represents the average number of years of education attained by adults.
b. Expected years of schooling: It refers to the number of years a child of school-going age is expected to receive education.

3. Gross national income (GNI) per capita: It measures the average income of a country's residents, indicating their standard of living and economic well-being.

The HDI combines these three dimensions to provide a comprehensive assessment of human development in a country.
