What is human development index?

The human development index is used to measure the prosperity of a country which is made by the United Nations Development Program(UNDP). The human development index is measured based on three categories:
  • Life expectancy, how long a person will live
  • Knowledge, adult literacy rate
  • Standard of living, GDP per capita in U.S. dollars
The human development index measures if a country is developed, developing or underdeveloped and it is expressed as a value between 0-1, the higher the number is, the more developed a country is. And the three categories are also rated between value from 0-1.
The formula used to calculate the human development index is:
Human development index = 1/3(life expectancy) + 1/3(knowledge) + 1/3(GDP)
The human development index draw attentions to the government, corporations and organization to focus not just on GDP, and human development index also shows how the quality of life in a country can be affect positively and negatively by economic policies.
