Demographics of Bosnia and Herzegovina
All standard varieties are based on the Ijekavian varieties of the Shtokavian dialect (non-standard spoken varieties including, beside Ijekavian, also Ikavian Shtokavian). Serbian and Bosnian are written in both Latin and Cyrillic (the latter predominantly using the Latin script), whereas Croatian is written only in Latin alphabet. There are also some speakers of Italian, German, Turkish and Ladino. Yugoslav Sign Language is used with Croatian and Serbian variants.
