Stress that the availability and use of accessible, timely, reliable and high-quality disaggregated data underpins our efforts to leave no one behind by, inter alia, identifying inequalities. Such data should measure poverty in all its forms and dimensions as well as progress on sustainable development, to reveal inequalities, gaps, progress and recurrent challenges, identify innovative solutions and inform the implementation of the 2030 Agenda at all levels. We are committed to developing broader measures of progress to complement gross domestic product. We urge Governments and international organizations, including the United Nations system, international financial institutions and other relevant stakeholders, to assist developing countries in further building and strengthening capacities for data collection, disaggregation, dissemination and analysis at all levels, taking into account that the global review of the 2030 Agenda will be based primarily on national official data sources. We welcome the decision of the Statistical Commission on the global indicator framework for the Sustainable Development Goals and targets prepared by the Inter-Agency and Expert Group on Sustainable Development Goal Indicators, which is a practical starting point, and look forward to its implementation and continual improvement in an inclusive and transparent manner;
