Out of curiosity, and for the sake of philosophical clarity, I'd like to ask that when you say like "Finnish people are X and Swedish people are more Y", do you mean

1. 100.00% of people born and raised in Finland are X, while 0.00% of Swedish people aren't X but instead 100.00% of Swedes are Y
2. 89.7% of Finnish people are X, while 92% of Swedish people are Y and non-X
3. 52% of Finnish people (that counts as majority and justifies the usage of shorthand general expressions like 'Finnish culture is X') are X, only 20% of Finnish people are Y - while in Sweden 48% of people are X and 23% are Y (so it is justified to say that Swedish culture is less X and more Y than Finnish culture)
4. 28% of Finnish people are strongly X, 30% are somewhat X, and the remaining 42% are little X, and 28% + 30% makes a majority so it is justified to say that overall the general Finnish culture is X, while in Sweden the numbers are 15%, 32% and 53%, so that they score lower on strong-X and on average are less X than the Finnish population
5. None of the above, as there is this semi-hegelian entity called 'national culture' which affects everyone and is somewhat independent from what individual people feel, think and believe, as the sociological realm obeys its own laws and mechanics, so that we can pinpoint and discuss those nation-spirits or regional cultures in abstract, independently of how large percentage of the population actually believes or follows the traits of their national culture
