Quite close to the bottom of each name page you find a table "Name Count per Country". As every country's statistics office publishes different kind of numbers, producing a table with all countries together was quite a challenge!
This is what you can find in the tables:
The National statistics office of Denmark [1] publishes only main names. This means we have no information about middle names in Denmark.
The National Population Register Centre of Finland [2] publishes only the total number of names. This means we have no information how many of the names are first names and how many are second/middle names. A "specialty" of the Finland statistics is that they publish the count of "more than 0 but less than 5" without an information about the gender. In this case we count 1 and try to assign it to the correct gender to get the numbers as correct as possible.
The Statistics office of Greenland [3] publishes the number of first names and the number of second/middle names. Unfortunately, they do not show the gender of the name. That is why we can only give you the total amount of name bearers. For both gender names, we use a white bar in the commonness column instead of the blue or red ones like the Icelandic example below.
The National statistics office of Iceland [4] publishes the number of first names and the number of second/middle names. Unfortunately, they do not show the gender of the name. That is why we can only give you the total amount of name bearers. For both gender names, we use a white bar in the commonness column instead of the blue or red ones.
The National statistics office of Norway [5] publishes only main names. This means we have no information about middle names in Norway.
Fun fact: In the rare case a name is used just as a middle name, the number of bearers is given, but the gender information is not available.
The National statistics office of Sweden [6] publishes everything: Count of first names, count of second/middle names and the gender.
