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
For various reasons—mainly related to nationalism and armed conflict—the numbers of Italian speakers in Croatia declined during the 20th century, especially after the Second World War in a period known as the Istrian exodus, when about 90% Italian-speaking Istrians and Dalmatians left Yugoslav dominated areas in the eastern Adriatic. The 2001 census in Croatia reported 19,636 ethnic Italians in the country.
