How should child poverty in the UK be defined? And how should it be measured? These are questions being considered by the UK Parliament’s cross-party Work and Pensions Committee in their inquiry ‘Children in poverty: Measurement and targets’. Over the course of the next few weeks, the committee is taking evidence from representatives of anti-poverty organisations, researchers and other witnesses to reflect on current practice regarding monitoring child poverty in the UK. As part of its first oral evidence session, I was asked to give evidence in relation to international practice of measuring child poverty. So how is child poverty currently monitored in the UK?
