COVID-19 has come to stay with us, but we can still take a deep breath today and look back at what has happened so far. On an individual level, quite a lot of us didn’t survive. How many of these people can we found in Wikidata? What do we know about them? Let’s start closest to where I live, Europe.<\/p>\n\n\n\n

Try <\/a>it!<\/a><\/p>\n\n\n\n Version 2.0<\/strong><\/p>\n\n\n\n Later on I noticed two things. <\/p>\n\n\n\n First, it would have been nice to have a link to the Wikipedia page of the person, if there, in some of the major European languages – or my local ones, Finnish and Swedish.<\/p>\n\n\n\n Second, the statistics query included duplicate records and thus gave incorrect counts.
