Measuring the Digital Transformation maps existing indicators drawn from a wide range of areas including education, innovation, trade, economic and social outcomes against current digital policy issues, as presented in Going Digital: Shaping Policies, Improving Lives (OECD, 2019). By so doing, it identifies gaps in the current measurement framework and assesses progress made by several initiatives towards filling these gaps, as documented in the 19 roadmap sections of the publication. The overarching objective of Measuring the Digital Transformation is to advance the measurement agenda by building on these roadmaps and a wide body of ongoing work in national and other international organisations, as well as areas already identified in Measuring the Digital Economy: A New Perspective (OECD, 2014) and in the G20 Toolkit for Measuring the Digital Economy (G20, 2018).The 2018 Argentine G20 Presidency, in collaboration with a steering committee of international organisations (IOs) led by the Organisation for Economic Co-operation and Development (OECD) and comprising the International Telecommunication Union (ITU), the United Nations Conference on Trade and Development (UNCTAD), the European Union, the World Bank Group (WBG), the International Monetary Fund (IMF), and the International Labour Organization (ILO), has produced a G20 Toolkit for Measuring the Digital Economy. The toolkit highlights methodological approaches and indicators used to monitor the digital economy, and key gaps and challenges regarding digital economy measurement for further study. See Annex 3 of the G20 Digital Economy Ministerial Declaration, 24 August 2018, Salta, Argentina.Several international organisations are contributing to the measurement of the digital transformation through initiatives, some of which are described in the G20 Toolkit for Measuring the Digital Economy. These include, but are not limited to, work on key ICT indicators within the Partnership on Measuring ICT for Development led by the ITU, UNCTAD and the United Nations Educational, Scientific and Cultural Organization (UNESCO) Institute for Statistics (UIS). The OECD works closely with several of these organisations, including the World Trade Organisation (WTO) on the issue of measuring digital trade, and the IMF on measuring the implications of the digital economy for macroeconomic statistics.
