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.
