Slavs
Slavs are the largest ethno-linguistic group in Europe. Present-day Slavic people are classified into East Slavs (chiefly Belarusians, Russians, Rusyns, and Ukrainians), West Slavs (chiefly Czechs, Kashubs, Moravians, Poles, Silesians, Slovaks and Sorbs), and South Slavs (chiefly Bosniaks, Bulgarians, Croats, Macedonians, Gorani, Pomaks, Montenegrins, Serbs and Slovenes).
Ukraine
Similar historical cleavages also remain evident at the level of individual social identification. Attitudes toward the most important political issue, relations with Russia, differed strongly between Lviv, identifying more with Ukrainian nationalism and the Ukrainian Greek Catholic Church, and Donetsk, predominantly Russian orientated and favourable to the Soviet era, while in central and southern Ukraine, as well as Kiev, such divisions were less important and there was less antipathy toward people from other regions (a poll by the Research & Branding Group held March 2010 showed that the attitude of the citizens of Donetsk to the citizens of Lviv was 79% positive and that the attitude of the citizens of Lviv to the citizens of Donetsk was 88% positive). However, all were united by an overarching Ukrainian identity based on shared economic difficulties, showing that other attitudes are determined more by culture and politics than by demographic differences. Surveys of regional identities in Ukraine have shown that the feeling of belonging to a "Soviet identity" is strongest in the Donbas (about 40%) and the Crimea (about 30%).
