Human Development Index:

The Human Development Index (HDI) is a comprehensive statistic used to classify countries into four levels of human development: Very high, High, Medium, and Low. The scale ranges from 0 to 1, with 1 being the highest level of development and 0 being the lowest level of development. The HDI aims to reflect average achievement in three basic aspects of human development: living a long and healthy life, being knowledgeable, and enjoying a decent standard of living.

Life expectancy at birth:

Life expectancy at birth is one of the three basic aspects of human development used to calculate the HDI. It reflects the average number of years a newborn baby is expected to live based on current mortality rates. Countries with higher life expectancies generally have higher HDI scores.

Average number of years of education:

The second aspect used to calculate the HDI is the average number of years of education. This reflects the expected years of schooling for a child starting at age 5 and the average years of schooling for adults in the population. Countries with higher levels of education generally have higher HDI scores.

Gross National Development:

The third aspect used to calculate the HDI is Gross National Development. This reflects the per capita income of a country and aims to measure the standard of living. Countries with higher per capita income generally have higher HDI scores.
