> It might be more interesting to discuss the median hours worked (or any of a number of other percentiles), but it's not obvious those figures are public.
In particular, it looks like as mentioned, most employees in Denmark fall in the 35-39h bucket (nearly 4x the size of the next biggest bucket, 40+ hours). Meanwhile, if you look at the US, the 40+ bucket is more than 10x the size of any other. But it's not exactly a US vs Scandinavia situation -- Sweden has just under 70% of its workforce also working 40+ hour weeks, higher than the UK or Germany.
Okay. It seems that the cited numbers are from https://en.wikipedia.org/wiki/List_of_countries_by_average_a... which in turn is derived from OECD data, which also allows you to view employees by bands of hours worked per week:
