The use of this multidimensional approach to poverty analysis has become consolidated in a number of spheres. Since 2011, the indicators in the Human Development Report of the United Nations Development Programme (UNDP) have included the multidimensional poverty index (MPI) based on a proposal by Alkire and Santos (2010), which combines 10 indicators to reflect deprivations in the three traditional dimensions of human development (health, education and quality of life) in 104 countries (see box 1.3 in chapter I). This is considered the first scientific estimate of child poverty in the developing world (Expert Group on Poverty Statistics (Rio Group), 2007).
