Dialects of Serbo-Croatian
Kajkavian is spoken in North Croatia, including the capital Zagreb, as well as in a few enclaves in Austria, Hungary, and Romania. Though its speakers are ethnic Croats and Kajkavian is thus generally considered a dialect of Serbo-Croatian, it is closer to neighboring Slovene than it is to Chakavian or Shtokavian. The Kajkavian area of Croatia is bordered on the northwest by Slovene language territory. It is bordered on the east and southeast by Shtokavian dialects roughly along a line that was the former division between Civil Croatia and the Habsburg Military Frontier; in southwest along Kupa and Dobra rivers, it persisted in ancient (medieval) contact with Chakavian dialects.
Croats of Serbia
The 1910 Austro-Hungarian census also showed large differences in the numbers of those who considered themselves Bunjevci and Šokci, and those who considered themselves Croats. According to the census, in the city of Subotica there were only 39 citizens who declared Croatian as their native language, while 33,390 citizens were listed as speakers of "other languages" (most of them declared Bunjevac as their native language). In the city of Sombor, 83 citizens declared Croatian language, while 6,289 citizens were listed as speakers of "other languages" (mostly Bunjevac). In the municipality of Apatin, 44 citizens declared Croatian and 7,191 declared "other languages" (mostly Bunjevac, Šokac and Gypsy).
