The Human Development Index (HDI) is a statistical composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of human development.
A lot of the time I'd prefer to see "HDI recalculated without income" because income per capita doesn't seem like a direct indicator of human development. It's more of a proxy measure. Of course, I could say the same thing about how it measures education. Educational outcomes (like highly developed literacy) are better than how many years of schooling someone has. But these better measurements are also probably harder to collect across a broad group of countries.
