many of its writers to move to the western Ukrainian region of Galicia which was under more liberal Austrian rule; after the 1860s the majority of Ukrainian literary works were published in Austrian Galicia. During this period Galician influences were adopted in the Ukrainian literary language, particularly with respect to vocabulary involving law, government, technology, science, and administration. Current usage The use of the Ukrainian language is increasing after a long period of decline. Although there are almost fifty million ethnic Ukrainians worldwide, including 37.5 million in Ukraine in 2001 (77.8% of the total population at the time), the Ukrainian language is prevalent mainly in western and central Ukraine. In Kyiv, both Ukrainian and Russian are spoken, a notable shift from the recent past when the city was primarily Russian-speaking. The shift is believed to be caused mainly by an influx of migrants from western regions of Ukraine but also by some Kyivans opting to use the language they speak at home more widely in public settings. Public signs and announcements in Kyiv are displayed in Ukrainian. In southern and eastern Ukraine, Russian is the prevalent language in most large and some small cities. According to the Ukrainian Census of 2001, 87.8% of people living in Ukraine were fluent in Ukrainian. In August 2022, a survey in Ukraine by Rating Group found that 85% said they speak Ukrainian or Ukrainian and Russian at home, 51% only Ukrainian, an increase from 61% and 44% in February 2014. In the same survey, 76% considered Ukrainian their native language (), up from 57% in July 2012, including 30% of Russian-speakers. Popular culture Music Ukrainian has become popular in other countries through movies and songs performed in the Ukrainian language. The most popular Ukrainian rock bands, such as Okean Elzy, Vopli Vidopliassova, BoomBox perform regularly in tours across Europe, Israel, North America and especially Russia.
