Countries with lower HDI/IHDI than Sri Lanka (lol @ Turkey)

Inequality-adjusted Human Development Index (IHDI) The IHDI combines a country's average achievements in health, education and income with how those achievements are distributed among country's population by “discounting” each dimension's average value according to its level of inequality.
