Russia or the USSR? A new quiz from Meduza based on the last Soviet population census

Thirty years ago this January, the USSR held what would be its last ever population census. Meduza studied this Soviet artifact and compared it to the most recent Russian census (conducted in 2010). The result of our heroic labor is this quiz, where you must guess which statistics describe the late Soviet Union and which describe the Russian Federation of nine years ago. Sounds pretty easy? Let's see about that.
