Question

Explain how is HDI calculated? What does it show?

Answer 1

.Answer:The Human Development Index HDI is defined as the composite statistics used to rank countries by levels of human development. The HDI is a measure of health, education and income. It measures the average achievements in a country in these three basic dimensions of human development, calculated into an index

Explanation:

older versions of the HDI were calculated using the following indicators:

   Health - Life expectancy at birth

   Education - measured by adult literacy and the combined primary, secondary and tertiary enrolment ratio

   Income - measured by GDP per capita (PPP US$)

The indicators of the three dimensions are calibrated and combined to generate an HDI score between zero and one. Countries are grouped into four human development categories or quartiles: very high, high, medium and low. A country is in the very high group if its HDI is in the top quartile, in the high group if its HDI is in percentiles 51–75, in the medium group if its HDI is in percentiles 26–50, and in the low group if its HDI is in the bottom quartile.
