Human development index

Human development index


The HDI is a measure of development using an index which includes three main sections (called dimensions) with separate indicators feeding into three separate indices, which are equally weighted in the final HDI index:

A long and health life

Life expectancy at birth

Which helps create the life expectancy index


Expected years in schooling

Mean years in schooling

Which creates an education index

A decent standard of living;

Gross national income (GNI) per capita

Which gives the GNI index

The final HDI index ranges from 0 – 1.
