The chapter presents MPIs as a useful and popular complement to countries' national monetary poverty measures, as can be seen from the examples of countries that use national MPIs (and their associated dashboards) as official statistics. Step by step guidelines are provided on how to design and use a national MPI for policy. The chapter also introduces some internationally comparable MPIs, for example the one published by UNDP, and shows what value-added emerges from comparable MPIs.
