The Human Development Index (HDI) is a composite index that ranks countries based on four key indicators (3 dimensions):

• Life expectancy in years (health)
  

• Expected years of schooling (education)
  

• Mean years of schooling (education)
  

• Gross national income per capita (standard of living)
  

Equal weighting (1/3) is given to each of the above dimensions: (1) health, (2) education, and (3) standard of living.

And the resulting index value is a normalized number between 0 and 1, with the latter number representing the maximum possible value.

Generally speaking, a country is thought to be developed or advanced when it has an HDI greater than 0.8.

The way you calculate each dimension’s index value is by using the minimum and maximum limits set out by the United Nations
