National statistical offices have an established position on the information market, presenting credible and reliable data to shape public policies. However, due to digital transformation, the rapidly developing new data ecosystems are currently a challenge for national and supranational systems of official statistics. New data sources, data ownership, access, conditions for reuse, ethics, privacy, confidentiality, and transparency are the issues of deep discussions on many fora, not only strictly statistical. New legislative initiatives, policies, roles, and functions for data intermediaries and stewards indicate the need to increase national statistical offices' potential, activity, and responsibility for shaping and advancing national data governance systems. This session is devoted in a broader context to the issue of the role of scientific societies in the conditions of deepening digitization and datafication processes, with particular emphasis on strategic paths of cooperation with national systems of official statistics, for delivery of the public good.
