I'm making a map estimating the percentage of the population that is white in each European country. Since the demographic data is extremely inconsistent in methodology and tracking for different countries, I will estimate based on the best available data, sometimes combining them with other relevant information for a better estimative. The definition of white here is someone of predominantly European ancestry regardless of nationality, so 'Kazakhs' in Germany would be mostly counted as they are in fact ethnic Germans, but not Turks. Adding up everyone with no foreign background and immigrant from European country or background from there doesn't work since the definition of what constitutes an immigration background varies, so keep that in mind. I've only done Germany and Sweden as of now, but if you've got data on your country that you estimated, it would help.
Germany: 83.7%
Sweden: 78.9%
