Sunni Muslims have historically lived in the cities of Albania, while Bektashis mainly live in remote areas, whereas Orthodox Christians mainly live in the south, and Roman Catholics mainly live in the north of the country. However, this division does not apply nowadays. In a study by Pew Research, 65% of Albanian Muslims did not specify a branch of Islam that they belonged to. The Albanian census doesn't differentiate between Bektashis and Sunnis, but instead between Bektashis and "Muslims", but since Bektashis are in fact Muslim many were listed as Muslims. Bektashi-majority areas include Skrapari, Dishnica, Erseka and Bulqiza while Bektashis also have large, possibly majority concentrations in Kruja, Mallakastra, Tepelena, large pockets of the Gjirokastër and Delvina Districts (i.e. Gjirokastër itself, Lazarat, etc.), and Western and Northeastern parts of the Vlora district. There are also historically substantial Bektashi minorities around Elbasan, Berat, Leskovik, Perm, Saranda and Pogradec. In Kosovo and Macedonia there were pockets of Bektashis in Gjakova, Prizren and Tetova. In the Albanian census, a few of these areas, such as Skrapari and Dishnica, saw the Bektashi population mostly labeled "Bektashi" while in most other areas such as Kruja it was mostly labeled "Muslim". The classification of children of mixed marriages between Sunnis and Bektashis or the widespread phenomenon of both groups marrying Orthodox Albanians also have inconsistent classification and oftentimes the offspring of such unions associate with both of their parents' faiths and occasionally practice both.
