This animated graph (data-visualization) shows the development of the weekly, COVID-19 incidence (infected per 100.000) in 9 different age-groups in Denmark in the period from week 1 to 45 in 2021.
Info on the graph is in Danish! ‘Uge’ means ‘week’. If you think that it is too slow, you can drag it to week 39 (at 1:18), where it speeds up!
At last, I show how big a part of the population, the different groups make up.
