The total transfer required to bring all poor people up to the poverty line is simply the sum of all the poverty gaps in a population (30+20+10+0+0), or the multiplication of the country's poverty gap index by both the poverty line and the total number of individuals in the country (PGIP l N). By incorporating the different dimensions, the MPM can present the extent to which these deprivations arise and overlap. The Poverty and Shared Prosperity 2022 report (World Bank, 2022) shows that almost 4 out of 10 multidimensionally poor individuals (39 percent) are not captured by monetary poverty, as they are deprived in nonmonetary dimensions alone.
