I am always a bit saddened that Russia doesn’t participate in the Eurobarometer polls, but fortunately, I found that VCIOM asked rather similar questions in polls from 2002 and 2010.
The methodology is a bit different. Eurobarometer defined “being comfortable” if one of your children was in a love relationship with [member of ethnic group] and you rated your level of Comfort with that in the region of 7-10 (out of 10), or indifference. The Russian poll asks if you would approve, disapprove, or be indifferent towards one of your close relatives (son, daughter, grandkid) marrying [member of ethnic group].
I think the questions are close enough for direct comparisons to be meaningful by summing the percentage of Russians who either approve or are indifferent.
|% Russians ok with kids marrying:||2002||2010|
|Latvians, Estonians, Lithuanians||61%||57%|
|Georgians, Armenians, Azeris||38%||37%|
|Germans, Frenchs, English||66%||61%|
In terms of marriage preferences, Russians seem to be less philo-Semitic than Poles, about the same as Czechs, Lithuanians, and Romanians, and more philo-Semitic than Slovaks.
They are also fully within the bands of normality for Eastern Europe so far as marriages with Muslims go.
