Up until 1990, the world relied on GDP and similar methodologies to measure the quality of life of citizens and the development in a country. However, in 1990, Mahbub ul Haq and Amartya Sen developed a new methodology for measuring the quality of life in a country. Unlike other metrics, Human Development Index (HDI) considers critical factors such as the likelihood of:

1) A long and healthy life (measured by life expectancy)
2) Access to knowledge (measured by mean years of education)
3)A decent standard of living (Gross National Income (GNI) per capita).
