Considering recent examples and participatory consultations, a core subset of dimensions is likely to include living standards, services, health, education, and the lived environment. It is desirable that the national MPI includes the dimensions of living standards, services, health, education, work and the lived environment. If national priorities are met (these have priority), and if in time, harmonized data are available, then for low marginal costs, both national and comparative measures can be built for UNECE countries.
