In partnership with the United Nations Development Programme (UNDP), DPA provided support to the Europe and Central Asia Regional Hub in Istanbul for the project “Measuring the Unmeasured” to contribute to SDG measurement and achievement. The effective use of data for public policy was of critical importance to the UN in its efforts to strengthen evidence-based programming and policy development. In particular, generating, analyzing, presenting, and using data was vital to global and regional efforts to monitor and promote the Sustainable Development Goals (SDGs). Our project aimed to scope, develop, and test different methods for measuring Tier III indicators of high SDG priorities for 11 countries in the Arab States, Europe and Central Asia, and Asia Pacific, with the main goal of utilizing this information in policy responses.
