The paper is based on a multi-dimensional poverty analysis carried out by the Center for Poverty Analysis. The idea of mental wellbeing is an important concept in this field. There are several studies that indicate that income and happiness are not linked above very low levels of income, and therefore there has been an increasing interest among both researchers and policymakers in the non material dimensions of wellbeing. A module developed by the Oxford Poverty and Human Development Initiative using subjective indicators as well as psychological or mental health indicators was piloted in the Badulla District of Sri Lanka. This module explores how men and women experience non material wellbeing in different ways. It provides a rich data set that measures and understands the various dimensions of mental wellbeing in a Sri Lankan context.
