for context: there are 5.328M people in Norway.
so, 0.14% of men in Norway have my first name.
now if you remove the H, as is far more commonly done (we have dropped the TH phoneme in modern Norwegian), there are more:
> There are 20 838 men that have Tor as [their] first name
> There are 5 019 men who have Tor as [their] only first name
so, altogether, 0.53% of men in Norway have Thor/Tor as their first name.
