List of countries by Sen social welfare function

The social welfare function, proposed by Amartya Sen in 1973, is a measure of a society's overall welfare.

Methodology

It is calculated as the product of GDP per capita and the difference between 1 and the society's gini coefficient:

W_\mathrm{Gini} = \overline{\text{Income}} \cdot \left( 1-G \right)

The table below shows Sen's social welfare function using data from the CIA and another version using data from the IMF and UN. The GDP per capita numbers are adjusted for purchasing power parity.
