Croatia
A 2011 survey revealed that 78% of Croatians claim knowledge of at least one foreign language. According to a survey ordered by the European Commission in 2005, 49% of Croatians speak English as the second language, 34% speak German, 14% speak Italian, and 10% speak French. Russian is spoken by 4% each, and 2% of Croatians speak Spanish. However, there are large municipalities that have minority languages that include substantial populations that speak these languages. An odd-majority of Slovenes (59%) have a certain level of knowledge of Croatian. The country is a part of various language-based international associations most notably the European Union Language Association.
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.
