But why would you need to correct for that? If more of the labor force works part time, more of the labor force is working fewer hours. Are you assuming these part time workers are carrying multiple jobs which aren't being listed in sum (eg 20 Hours/week at Job A, 10 Hours/week at job B for 30 hours, instead of 15 if each job is separate?)

More likely that the part time force consists of families where both parents work eg 60-80%. This is at least quite common for friends around me.

Perhaps ‘correcting’ is the wrong word. But the title feels like: this is a ranked list which countries work hardest. I think the figure fails to capture that a family where both parents work 30 hours is not working less than a family where only one parent works 50 hours.

In my opinion, if that’s the comparison we want to make, it would be more fair to look at average hours worked per capita, or average hours worked per capita between ages 16-70, or something similar. That would capture both average hours and labor force participation.

To the other extreme: why would you correct for unemployment (which is what happens if you measure worked hours only for those who have a job)? After all an unemployed person is a "part-time" worker where the fraction of time spent working is exactly zero.

Agreed. Hours worked per prime-age inhabitant, would be very interesting.
