Ukraine
Among those Ukrainians who declared to believe in Orthodoxy, 38.1% declared to be members of the Ukrainian Orthodox Church of the Kievan Patriarchate (a body that is not canonically recognized by the Eastern Orthodox Church), 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.
