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.
Socialist Federal Republic of Yugoslavia
The population of Yugoslavia spoke mainly three languages: Serbo-Croatian, Slovene and Macedonian. The Serbo-Croatian language was spoken by the populations in the federal republics of SR Serbia, SR Croatia, SR Bosnia and Herzegovina, and SR Montenegro – a total of 12,390,000 people by the late 1980s. Slovene was spoken by approximately 2,000,000 inhabitants of SR Slovenia, while Macedonian was spoken by 1,210,000 inhabitants of SR Macedonia. National minorities used their own languages as well, with 506,000 speaking Hungarian (primarily in SAP Vojvodina), and 2,000,000 persons speaking Albanian in SR Serbia (primarily in SAP Kosovo), SR Macedonia and SR Montenegro. Turkish, Romanian (primarily in SAP Vojvodina), and Italian (primarily in Istria and parts of Dalmatia) were also spoken to a lesser extent. The Yugoslav Albanians, almost exclusively Ghegs, chose to use the unified literary language of Albania predominantly based on Tosk Albanian (a different dialect), for political reasons.
