Urums practice Eastern Orthodox Christianity. Throughout history, they represented an isolated cultural group and rarely settled in towns populated by the Romaioi, despite sharing Greek heritage with them. Unlike Greek, Urum has never been a language of secondary education in Ukraine. Turkologist Nikolai Baskakov estimated that by 1969, 60,000 people spoke Urum as a native language. According to the All-Ukrainian Population Census of 2001, only 112 of the Donetsk Oblast's 77,516 Greeks listed languages other than Greek, Ukrainian and Russian as their mother tongue.
