Human Development Index has been revised in 2010 owing to a few limitations. HDI is believed to estimate the 'potential' human development that could be achieved if there were no inequality. The revised Inequality-adjusted Human Development Index (IHDI) is the actual level of human development (accounting for inequality). Secondly, HDI does not take into account several factors, such as the net wealth per capita or the relative quality of goods in a country. This situation tends to lower the ranking of some of the most developed countries, such as the G7 members and others.
