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.
Languages of Slovenia
The population of Slovenia has become more diverse in regard to its language through recent decades but is still relatively homogenous — Slovene was in 2002 the first language of 87.8% of the inhabitants. It was followed by Croatian (2.8%), Serbian (1.6%) and so-called Serbo-Croatian (1.6%). Italian and Hungarian language, protected by the Constitution of Slovenia, had lower numbers of native speakers.
