Following the schedule of joint project of the Kiev International Institute of Sociology (KIIS) and the Levada Center (Russia), KIIS has conducted a nationwide opinion poll regarding attitude of Ukrainians towards Russia and attitude of Russia towards Ukrainian population, which was held during the period of September 21 – October 3, 2012. 2043 respondents were interviewed; the investigation covered all regions of Ukraine, including Kiev and Crimea Region; the sample was random and is deemed to be representative for population of Ukraine aged 18 and above.

The majority of Ukrainians (65%) support the idea of making Russian language and languages of national minorities official in the regions of Ukraine, where most of the population (50% or more) so desires. 27% of Ukrainians do not support this idea.

In the event of a referendum on Ukraine's accession to the EU, there are more Ukrainians who are ready to vote "for" than "against" (40% vs. 33%). Supporters of EU membership dominate in the Western and Central regions (67% vs. 13% and 46% vs. 26%); and the ones who are against the accession live in the Southern and Eastern regions (45% vs. 22% and 50% vs. 24%).
