For all countries, you seem to be quoting percentages based on (primary) language, not nationality or self-identified ethnicity. Just curious, do you feel it's impossible for a native Russian speaker living in Latvia to identify as Latvian, perhaps both Latvian and Russian? The number you present for Finland is highly misleading, by the way. We have around 6 % of Swedish-speaking Finns but they almost all speak Finnish, have very deep roots in Finland and certainly identify as Finns just as much as the rest of us -- and definitely not as Swedes. Swedish is even the second official language. As for the rest, I'm sure most of the citizens growing up in an Estonian, Russian, Somali etc. speaking household identify as Finns, too.
