Why are MPI estimates higher than national poverty estimates in some countries?

The MPI, like the $1.25 per day line, is a globally comparable measure of poverty. It measures acute multidimensional poverty, and only includes indicators that are available for many countries. National poverty measures are typically monetary measures, and thus capture something different. The fact that there are differences does not mean that the national poverty number, or the MPI headcount is wrong— these simply measure different concepts of poverty. At the same time, just as national poverty measures, in contrast, are designed to reflect the domestic situation more accurately and often differ in very useful ways from the $1.25 measure, some countries may wish to build a national multidimensional poverty index that is tailored to their context, to complement this international MPI.
