Data Trend Inequality-Adjusted Happiness in Nations

Inequality-adjusted happiness is an index which denotes the degree towhich a country combines a high average level of happiness with low inequality in happiness. The index gives equal weight to level and inequality of happiness. Its theoretical range is between 0 and 100.
Computation: iah = 4 + 9.6 m – 3.97sd, where: m is mean and sd is the standard deviation of a happiness distribution.
The concept and computation is discussed in Veenhoven, R. & Kalmijn, W. Inequality adjusted happiness in nations. Egalitarianism and utilitarianism married together in a new index of societal performance. (paper under review).
