Comparing Approaches to the Measurement of Multidimensional Child Poverty

The Sustainable Development Goal (SDG) target 1.2 implies that both monetary and non-monetary or multidimensional (MD) child poverty would be measured and monitored, and that the associated indicators would be defined nationally. However, very few countries routinely measure child MD poverty. This paper seeks to provide some guidance on the topic by presenting and comparing two approaches which are now some of the most widely used. The first approach is the Multiple Overlapping Deprivation Analysis (MODA) which was developed by UNICEF. MODA is a child specific MD poverty measure rooted in the rights-based framework of the Convention on the Rights of the Child (CRC). The second measure we present and compare is the Multidimensional Poverty Index (MPI) developed by the Oxford Poverty and Human Development Initiative which has computed the MPI for over 100 countries using a universal global standard. We compare the global version of the measures, applying them to four countries: Cambodia, Ghana, Mali, Mongolia. The two approaches, while sharing many similarities, do not lead to the same results. In deciding on their individual strategy to measure and track SDG Target 1.2, countries will need to reflect on both the underlying purpose of the target, and to evaluate the inevitable trade-offs between the two approaches.
