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.
Istro-Romanian language
Since 2010, the Croatian Constitution has recognized Istro-Romanians as one of 22 national minorities. However, because of its very small number of speakers, living in about eight minor hamlets and two considerable villages, notably Žejane and Šušnjevica, there is no public education or mass media in Istro-Romanian language.
