概要	The capability approach, developed by Amartya Sen and given a concrete list-based form by Martha Nussbaum, evaluates individual well-being and social arrangements in the space of capabilities — the real freedoms people have to achieve the kinds of lives they have reason to value — rather than in the space of income, resources, or subjective utility. Measurement under the approach means identifying valued functionings, the resources and conversion factors that turn resources into functionings, and the freedom people enjoy to choose among them.	The Multidimensional Poverty Index applies the Alkire-Foster method, introduced by Sabina Alkire and James Foster in 2011, to measure poverty as the joint deprivation of individuals across several dimensions such as health, education, and living standards. Its signature is a dual-cutoff identification: a person is deprived in an indicator if they fall below that indicator's cutoff, and they are counted as multidimensionally poor only if their weighted count of deprivations crosses a cross-dimensional cutoff k. The headline measure is the adjusted headcount ratio M0 = H times A, the product of the share of people who are poor (incidence) and the average breadth of their deprivations (intensity).
