Singapore is one of the world's wealthiest countries "per capita", but its Gini coefficient is high in comparison to developed countries. Statistics on income inequality are published by the Singapore Department of Statistics. Without taking taxes and social transfers into account, Singapore's gini coefficient puts the country in the medium range. Nevertherless, the country remains on the "very high" category on the inequality-adjusted human development index (IHDI), a ranking similar to the Human Development Index (HDI), but with inequality also accounted for.
