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.
Italian language in Croatia
The 2011 Census in Croatia reported 17,807 ethnic Italians in the country (some 0.42% of the total population). Ethnologue reported 70,000 persons whose first language is Italian or Venetian in 1998 (referring to Eugen Marinov's 1998 data). This population was composed of 30,000 ethnic Italians and 40,000 ethnic Croats and persons declared regionally ("as Istrians"). Native Italian speakers are largely concentrated along the western coast of peninsula Istria. Because of Croatian trade and tourist relations with Italy, many Croats have some knowledge of the language (mostly in the service and tourist industries).
