Inequality-adjusted happiness is an index which denotes the degree to which 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.
Theoretical range is between 0 and 100.
Computation: IAH = 4 + 9.6 M – 3.97 SD, 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. (2005) Inequality adjusted happiness in nations. Egalitarianism and utilitarianism married together in a new index of societal performance.

1) Variable codes consist of two elements:
– IAH for inequality adjusted happinesss in the nation
– Nation code (two digit ISO code e.g., ‘be’ for Belgium)
2) Weighted average: EU-8 = Belgium x 0.037423 + Denmark x 0,19263 + France x 0,213337 + West-Germany x 0,243826 + Italy x 0,211549 + Luxembourg x 0,0001503 + Netherlands x 0,056975 + UK x 0,216118
