Comparing country experiences seems to be of considerable interest to UNECE member states. With both national and regional aims in mind, this chapter aims to support countries' exploration of rigorous multidimensional poverty measures, and to encourage the creation of data sources that would permit the generation of a regional MPI based on comparable indicators of non-monetary poverty. In the case of monetary poverty, national income poverty measures are used for national poverty reduction policies, while cross-national studies are conducted that draw on comparable measures such as the PPP$3.10/day poverty measure to elucidate good practices that would be relevant to other UNECE countries.
