Religious affiliation is diverse: Macedonians, Serbs, and Aromanians are mainly Orthodox, with the majority affiliated to the Macedonian Orthodox Church; Turks are almost entirely Muslim; those of Albanian ethnicity are largely Muslim, although Skopje also has a sizeable Roman Catholic Albanian minority, into which Mother Teresa was born; the Roma (Gypsies) represent a mixture (in almost equal numbers) of Muslim and Orthodox religious heritage.
