This paper presents new ways of conceptualising child poverty, in order to bring about action for change. It draws on research undertaken by the Children’s Policy Centre and the Poverty and Inequality Research Centre at The Australian National University over the past fifteen years and on wider debates and research to propose an innovative multidimensional approach. It presents a framework – MOR for Children – that will move beyond the current, limited approaches to childhood poverty measurement to assess the numbers of children living in multidimensional poverty, to develop a child-centred understanding of the multiple impacts of poverty, and to support the design and evaluation of child-inclusive policies.
