Demographics of Croatia
Croatian replaced Latin as the official language of the Croatian government in 1847. The Croatian lect is generally viewed as one of the three standard varieties of the Shtokavian dialect of Serbo-Croatian, a South Slavic language. Croatian is written using the Latin alphabet and there are three major dialects spoken on the territory of Croatia, with the Shtokavian idiom used as the literary standard. The Chakavian and Kajkavian dialects are distinguished by their lexicon, phonology, and syntax.
Italian language in Croatia
In the past the language had a much larger population than it does now: the Italian (Venetian speaking) population constituted (according to the Italian linguist Bartoli) nearly one third of Dalmatians in the second half of the 18th century. According to the Austrian census it had decreased from 22% in 1816 to 12.5% in 1853, down to a mere 2.9% in 1910.
