How is the number of poor people in each country calculated?

The number of people living in multidimensional poverty have been computed using the United Nations Department of Economic and Social Affairs/Population Division’s total population data for the year 2019 for all countries. This approach assumes a constant headcount ratio (obtained by applying the MPI methodology to the survey) which implies an assumption of no change in multidimensional poverty rates between the year of the survey and 2019.

In addition, every year the release of the MPI provides the number of people living in multidimensional poverty during the year of the survey. In countries with surveys conducted in a two-year period, i.e., 2015/2016, the population of the second year is used.
