Chakavian
Chakavian in its actual use is the least spoken Serbo-Croatian dialect, being spoken only by 12% Croats. It is now mostly reduced in southwestern Croatia along the eastern Adriatic: Adriatic islands, and sporadically in the mainland coast, with rare inland enclaves up to central Croatia, and minor enclaves in Austria and Montenegro. All areas of old contacts with Romance languages.
Languages of Slovenia
The population of Slovenia has become more diverse in regard to its language through recent decades but is still relatively homogenous — Slovene was in 2002 the first language of 87.8% of the inhabitants. It was followed by Croatian (2.8%), Serbian (1.6%) and so-called Serbo-Croatian (1.6%). Italian and Hungarian language, protected by the Constitution of Slovenia, had lower numbers of native speakers.
