← 1. 15-year-old students were asked, “During a typical weekend day [/weekday], how much time do you spend doing the following leisure activities?”, where the seven responses were: “Play video-games (using my smartphone, a gaming console or an online platform or Apps)”, “Browse social networks (e.g. <Instagram®>, <Facebook®>)”; “Browse the Internet (excluding social networks) for fun (e.g. reading news, listening to podcasts and music or watching videos)”, “Look for practical information online (e.g. find a place, book a train ticket, buy a product)”, “Communicate and share digital content on social networks or any communication platform (e.g. <Facebook®>, <Instagram®>, <Twitter®>, emails, chat)”, “Read, listen to or view informational materials to learn how to do something (e.g. tutorial, podcast)”, and “Create or edit my own digital content (pictures, videos, music, computer programs)”. The weekly average was calculated assuming five weekdays and two weekend days. OECD average does not include Canada, Colombia, France, Luxembourg, Mexico, the Netherlands, New Zealand, Norway or Portugal. Although the items were measured through separate sub-questions, the activities could be performed simultaneously, and their aggregates should be interpreted with caution.
