According to the latest census that took place, the following languages are common in Ukraine Ukrainian 67.5%, Russian 29.6%, Crimean Tatar, Urum (Turkic Greeks), Bulgarian, Moldovan/Romanian, Polish, Hungarian. The below table gives the total population of various ethnic groups in Ukraine and the primary language, according to the 2001 census. A 2016 survey conducted by the Razumkov Centre found that 70% of the population declared themselves believers in any religion, while 6.3% declared themselves non-believers, and 2.7% declared to be atheists. Of the total Ukrainian population, 81.9% declared to be Christians, comprising a 63.4% who declared to be Orthodox, 8.5% Greek Rite Catholics, 7.1% simply Christians, 1.9% Protestants, and 1.0% Latin Rite Catholics. Islam comprises 1.1% of the population, while Judaism and Hinduism were the religions of 0.2% of the population each. A further 16.3% of the population believed in some other religion not identifying in one of those listed hitherto; it may comprise Rodnovery and other faiths. Among those Ukrainians who declared to believe in Orthodoxy, 38.1% declared to be members of the Ukrainian Orthodox Church of the Kievan Patriarchate (canonized by the Eastern Church as of the 5 January 2019), while 23.0% declared to be members of the Ukrainian Orthodox Church of the Moscovian Patriarchate (which is an autonomous Orthodox church under the Russian Orthodox Church). A further 2.7% were members of the Ukrainian Autocephalous Orthodox Church, which, like the Kievan Patriarchate, is not recognized by the Eastern Orthodox Church. Among the remaining Orthodox Ukrainians, 32.3% declared to be "simply Orthodox", without affiliation to any patriarchate, while a further 3.1% declared that they "did not know" which patriarchate or Orthodox church they belonged to. Between the Soviet census of 1989 and the Ukrainian census of 2001, Ukraine's population declined from 51,706,600 to 48,457,020, a loss of 2,926,700 people or 5.7% of the 1989 population. However, this trend has been quite uneven and varied regionally. Two regions in western Ukraine — Rivne and Zakarpattia, saw slight population increases of 0.3% and 0.5% respectively. A third western Ukrainian region, Volyn, lost less than 0.1% of its population between 1989 and 2001.
