The Serbs are Orthodox and Kosovo albanians are majority muslim although there are some that are Catholic. I don't the exact numbers for Muslim and Catholics among the Albanians in Kosovo unfortunately, but there are others that usually post on the Balkans threads that have those figures.
85% muslim and 15% catholic I heard once.
Appreciation in advance, Hvala! The Four Seas.
There are Christian Albanians, but they are all in Albania, and a few in Montenegro. The Albanians in Kosovo (and Macedonia) are all Muslim. If there are any Catholic Albanians in Kosovo, they are an extremely small minority (maybe 1% of Kosovo's population) because they do not show up in any statistic I've ever seen.
