For instance, a person dissaving in retirement may have a very low, or even zero, income, but have a high level of consumption nevertheless. In practice, it may be useful to calculate the measure for several values of k. Robustness checks can be performed across all values of k.

It is calculated by adding up the proportion of total deprivations each person suffers (for example, in Table 2, Person 1 suffers 4 out of 6 deprivations and Person 4 suffers 6 out of 6) and dividing by the total number of poor persons. To measure poverty globally, however, we need to apply a poverty line that is consistent across countries. 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). If the data are binary or ordinal, multidimensional poverty is measured by the adjusted headcount, M0, which is calculated as H times A. Headcount poverty is multiplied by the average number of dimensions in which all poor people are deprived to reflect the breadth of deprivations. By incorporating the different dimensions, the MPM can present the extent to which these deprivations arise and overlap. If you multiply a country's poverty gap index by both the poverty line and the total number of individuals in the country you get the total amount of money needed to bring the poor in the population out of extreme poverty and up to the poverty line, assuming perfect targeting of transfers.
