The HDI was developed in 1990 by the United Nations to measure the levels of development.
It is a composite measure of development, i.e it takes into consideration 3 key variables in determining the level of human development:
The health dimension is assessed by life expectancy at birth,
the education dimension is measured by the mean of years of schooling for adults aged 25 years and more and expected years of schooling for children of school entering age.
The standard of living dimension is measured by gross national income per capita.
HDI is measured on a scale of 0 to 1.
Countries with the highest HDI are in Western Europe (e.g Norway’s is 0.949). North America, Australia (0.939).
The lowest measure is in Central Africa.
HDI is a composite measure, meaning more than one variable is taken into account.
