It's also quite interesting when you consider that the USSR was not a nation-state - and when you break it down by countries within the Soviet Union, there also some pretty shocking numbers. Ukraine and Belarus suffered disproportionately.

Belarus has the unfortunate distinction of exceeding even Poland's record, and by a long shot - by most estimates, 25-27% of the entire population of Belarus died in WWII, including some 90% of Belorussian Jews. The majority all known buildings in the country were leveled in the fighting or by the Germans - the occupation forces deliberately destroyed more than 5000 villages in the country, including some 600 villages that were burned with their entire populations. While not a huge country, it's not a small one either - almost 10 million at the start of the war. So on any scale, it was pretty tremendous.
