It is built from unit data structured to define deprivations for each chosen indicator and person. The deprivation profiles depict the 0-1 vector of deprivations each person does or does not experience. It uses these (weighted) vectors to identify who is poor, to aggregate information on poverty into a headline measure, and to generate the MPI as well as the incidence, intensity, and indicator composition of poverty. Because of its order of aggregation—first across indicators for each person and then across the population—the MPI captures interconnections between different deprivations for the same person.
