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.
Croats of Bosnia and Herzegovina
Croats of Bosnia and Herzegovina speak Croatian, a standardized variety of Serbo-Croatian language, spoken by the people of Bosnia and Herzegovina. Even though most of them speak in the Ijekavian, also the norm among Bosniaks and Bosnian Serbs, Ikavian is also used and was widespread in larger parts of Bosnia.
