Croatian language
Standard Croatian is the official language of the Republic of Croatia and, along with Standard Bosnian and Standard Serbian, one of three official languages of Bosnia and Herzegovina. It is also official in the regions of Burgenland (Austria), Molise (Italy) and Vojvodina (Serbia). Additionally, it has co-official status alongside Romanian in the communes of Carașova and Lupac, Romania. In these localities, Croats or Krashovani make up the majority of the population, and education, signage and access to public administration and the justice system are provided in Croatian, alongside Romanian.
Serbo-Croatian
Croatian is spoken by roughly 4.8 million, including some 575,000 in Bosnia and Herzegovina. A small Croatian minority that lives in Italy, known as Molise Croats, have somewhat preserved traces of the Croatian language. In Croatia, 170,000, mostly Italians and Hungarians, use it as a second language.
