in the country there is a very large population of Russians who are pro-Russian, also the autonomous region of Gagauza( Turkish ethnic people) in the south is also pro-Russia. the Moldovans/Romanians are divided ,but the majority (perhaps 65-70%) are for union

From what I have observed, there is not a very big difference between age or rural/urban

( I don't have statistics, just what I notice around me)
