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.
Slovenia
A significant number of people in Slovenia speak a variant of Serbo-Croatian (Serbian, Croatian, Bosnian, or Montenegrin) as their native language. These are mostly immigrants who moved to Slovenia from other former Yugoslav republics from the 1960s to the late 1980s, and their descendants. In 2002, 0.4% of the Slovenian population declared themselves to be native speakers of Albanian and 0.2% native speakers of Macedonian. Czech, the fourth-largest minority language in Slovenia prior to World War II (after German, Hungarian, and Serbo-Croatian), is now the native language of a few hundred residents of Slovenia.
