Kajkavian
The major cities in northern Croatia are located in what was historically a Kajkavian-speaking area, mainly Zagreb, Koprivnica, Krapina, Križevci, Varaždin, Čakovec. The typical archaic Kajkavian is today spoken mainly in Hrvatsko Zagorje hills and Međimurje plain, and in adjacent areas of northwestern Croatia where immigrants and the Štokavian standard had much less influence. The most peculiar Kajkavian dialect "(Baegnunski)" is spoken in Bednja in northernmost Croatia. Many of northern Croatian urban areas today are partly Štokavianized due to the influence of the standard language and immigration of Štokavian speakers.
Serbs of Croatia
Serbian language is officially used in 23 cities and municipalities in Croatia.
In April 2015 United Nations Human Rights Committee has 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. Serbian Foreign Minister Ivica Dačić said that his country welcomes the UN Human Rights Committee's report.
