Albanians
In Croatia, the Albanian language is one of the officially recognized minority languages of the country and is primarily spoken by the Albanians and Arbanasis. As defined in the 2011 census, the number of Albanians in the country was estimated to be 17,513. They are mostly concentrated in the coastal cities of Croatia and the capital city of Zagreb.
Croats of Slovenia
It seems however that the great majority of Croats living in Slovenia uses Slovene as their primary language of communication.
In 2001, only around 2,700 people spoke either Croatian or a combination of Croatian and Slovene at home, which is a significant decrease from in 1991, when their number was around 10,000.
