List of countries by inequality-adjusted Human Development Index

2022-24 UN Human Development Report (inequality-adjusted).svg This is a list of countries by inequality-adjusted Human Development Index (IHDI), as published by the UNDP in its 2024 Human Development Report. According to the 2016 Report, "The IHDI can be interpreted as the level of human development when inequality is accounted for," whereas the [[Human Development Index]] itself, from which the IHDI is derived, is "an index of potential human development (or the maximum IHDI that could be achieved if there were no inequality)." However the past several reports, including HDR 23/24 don't compare them in this way.

Methodology
The index captures the HDI of the average (calculated using not arithmetic, but geometric mean) person in society, which is less than the aggregate HDI when there is inequality in the distribution of health, education and income. Under perfect equality, the HDI and IHDI are equal; the greater the difference between the two, the greater the inequality.

The IHDI, estimated for the world and specific countries, captures the losses in human development due to inequality in health, education and income. Losses in all three dimensions vary across countries, ranging from just a few percent (Czech Republic, Slovenia) up to over 40% (Comoros, Central African Republic). Overall loss takes into account all three dimensions.
