Human Development Index is a tool developed by the United Nations to measure and rank countries based on the level of social and economic development. The HDI makes it possible to track changes in development levels from time to time and to compare development levels in different countries. The concept of HDI goes beyond income and growth to cover overall development with the object of improving the conditions of people from all angles. The organization that measures the HDI is the United Nations.
Three major indicators of the HID are as follows.
(a) Health: Without proper health facilities, no matter how much a country earns, it will not be able to provide basic facilities to its people.
(b) Education: Over the past few decades, education has become an important factor in leading a quality life. So, if the country has high income but the literacy rate is low, it cannot be considered developed.
