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.
Minority languages of Croatia
In the first years after introduction of new Constitutional Act on the Rights of National Minorities some local governments resisted implementation of its legal obligations. In 2005 Ombudsman report, municipalities of Vojnić, Krnjak, Gvozd, Donji Kukuruzari, Dvor and Korenica were mentioned as those that do not allow the official use of the Serbian language, although the national minority in these places meets the threshold provided for in the Constitutional Act. The report pointed out that Serbian minority in Vukovar can not use Serbian language although minority constituted less than one percent less population than it was prescribed by law. After 2011 Croatian census Serbs of Vukovar meet the required proportion of population for co-official introduction of Serbian language but it led to Anti-Cyrillic protests in Croatia. In April 2015 United Nations Human Rights Committee urged Croatia to ensure the right of minorities to use their language and alphabet. Committee report stated that particularly concerns the use of Serbian Cyrillic in the town of Vukovar and municipalities concerned. The Constitutional Court of Croatia upheld the legislation on the use of minority languages. It relied on a newly developed concept of national identity.
