Like other steps of inequality, Sen’s SWF is principally intended to measure money shipments, maybe not complete economic passions.

Rather this may trigger a state where on average folks are similarly less well-off. For these reasons, SWF can not be regarded as a way of measuring peoples hobbies, although it’s discovered to be an accurate list out of income inequality.
