While Niger has the highest percentage of MPI-poor, with 89.3 per cent of its entire population found to be living in multidimensional poverty, using the same MPI measure the five poorest regions in the world are in Chad and Burkina Faso. The OPHI researchers found that the very poorest region of all the 803 regions studied is Salamat in Chad, where nearly 98 per cent of its 354,000 inhabitants are measured as multi-dimensionally poor.
