This book addresses the use of information and communication technologies (ICTs) and the Internet at work in relation to the economy and society. It is designed to be a point of reference with respect to currently available statistics, and to mark progress towards the development of relevant new indicators on a broad range of issues. The aim is to: - Review the current set of internationally comparable ICT indicators in light of OECD policy priorities in the area of the digital economy, as formulated in the 2008 Seoul Ministerial Declaration and the 2011 High-Level Meeting on the Internet Economy; - Exploit the potential of existing official statistics and experiment with new metrics; - Identify data gaps and foreground the measurement agenda; and - Discuss the data infrastructure needed to measure ICT diffusion and impacts, including tools for the analysis of large datasets.
