The most common method measuring and reporting poverty is the headcount ratio, given as the percentage of the population that is below the poverty line.

The depth of poverty is the average 'gap' (G) between the level of deprivation poor people experience and the poverty cut-off line. M1 = H x A x G. Adjusted Squared Poverty Gap (M2): This measure reflects the incidence, intensity, and depth of poverty, as well as inequality among the poor (captured by the squared gap, S). M2 = H x A x S.
