"The Human Development Index was developed as an alternative to simple money metrics. It is an easy-to-understand numerical measure made up of what most people believe are the very basic ingredients of human well-being: health, education, and income. The first Human Development Index was presented in 1990. It has been an annual feature of every Human Development Report since, ranking virtually every country in the world from number one (currently Iceland) to number 177 (currently Sierra Leone)."
