The IHDI reduces human development achievements by the inequality in the distribution of health, education, and income within countries, and provides a fuller, multidimensional view of inequality.
At the global level, when accounting for inequalities, the 2017 HDI value of 0.728 falls to 0.582, the average loss of about 20 percent.
But a deeper look into data reveals that the overall (percentage) loss in HDI due to inequality ranges from 3.6 percent in Japan to 45.3 percent in Comoros, and the composition of inequality is vastly different between countries.
Explore the interactive visualization to see country-level composition of inequality.
