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.
Serbian language in Croatia
The Law on Use of Languages and Scripts of National Minorities provides for a mandatory co-official use of minority languages in municipalities of Croatia with at least one third of members of ethnic minoritiy. Municipalities Dvor, Gvozd, Jagodnjak, Šodolovci, Borovo, Trpinja, Markušica, Negoslavci, Biskupija, Ervenik, Kistanje, Gračac, Udbina, Vrbovsko, Donji Kukuruzari, Erdut and Vukovar, according to the provisions of law, are obliged to grant equal co-official use of Serbian language and Serbian Cyrillic alphabet. Law enforcement is facing great resistance in the part of the majority population, most notably in the case of Vukovar where it led to 2013 Anti-Cyrillic protests in Croatia.
